1.2.2 The Shareholders’ rights and obligations as Shareholders shall be regulated by the provisions of this Annex. No other provision of this Code shall apply to the regulation of the rights and obligations of Shareholders in their capacity as Shareholders.

1.2.3 It is acknowledged that on the Mandatory Ownership Transfer Date, the initial Mandated Parties became the Shareholders in BSCCo.

1.2.4 The Board may, in its discretion, refuse to register the transfer of a Share to an Eligible Party, or to allot a Share to an Eligible Party.

1.3 New Shareholders

1.3.1 Other than in respect of the initial Mandated Parties that became Shareholders in BSCCo on the Mandatory Ownership Transfer Date, as soon as possible after being directed to do so by the Authority or the Secretary of State (or, where relevant, nominated pursuant to a Licence), each Mandated Party will apply to become a Shareholder. Any Mandated Party from time to time that is not a Shareholder shall apply to become a Shareholder. Upon any such application, BSCCo shall either:

(a) procure the transfer to such Mandated Party of one Share then held by a nominee in accordance with paragraph 1.4; or

(b) allot to such Mandated Party one Share,

and shall register the transfer of such Share.

1.3.2 Where BSCCo has agreed, under paragraph 1.2, to register the transfer of a Share, or approved the allotment of a Share, to an Eligible Party, BSCCo shall either:

(a) procure the transfer to such Eligible Party of one Share then held by a nominee in accordance with paragraph 1.4; or

(b) allot to such Eligible Party one Share.

1.3.3 Save in the case of any nominee for the purposes of paragraphs 1.4.4 and 1.4.5:

(a) no person who is not a Mandated Party or an Eligible Party may at any time become a Shareholder; and

(b) no Mandated Party or Eligible Party shall hold more than one Share at any time,

and the Directors shall refuse to allot and/or to register any transfer of a Share that would result in a breach of this paragraph 1.3.3.

1.3.4 For the purposes of paragraphs 1.3.1(b) and 1.3.2(b) the Shareholders agree that, where no Shares are otherwise available for issue, they will exercise the voting rights attaching to their Shares to procure that all necessary steps are taken to create and/or authorise the issue of further Shares.

1.3.5 The price for each Share transferred or allotted under this Annex shall be £1.00, and:

(a) such amount shall be payable to the transferor on demand; and

(b) no premium may be paid in respect of the Shares.

1.4 Transfers, revocations and returns of Shares

1.4.1 An Eligible Party may transfer its Share to the BSCCo Nominee under this paragraph at any time.

1.4.2 A transfer of a Share by a Mandatory Party shall be permitted where, in respect of that Share and to the extent permitted by the relevant Licence, the Mandatory Licensee:

(a) delegates responsibility for holding that Share to another Party; or

(b) changes the Party to whom it has delegated responsibility for holding that Share,

in which case the Party to whom that Share has been transferred shall notify BSCCo and BSCCo shall (unless directed otherwise by the Authority) register the transfer of such Share.

1.4.3 A Shareholder must transfer its Share to the BSCCo Nominee under this paragraph (and BSCCo may give notice to that effect) where:

(a) that Shareholder ceases to be a Party;

(b) for a Mandated Party:

(i) where the Mandated Party is a Mandatory Licensee, the Licence has been surrendered or revoked;

(ii) where the Mandated Party holds the Share as a result of a delegation by a Mandatory Licensee, the Licence of that Mandatory Licensee has been surrendered or revoked; or

(iii) (unless the Secretary of State or Authority has accepted otherwise) where the Secretary of State or Authority suspends or revokes the direction that requires such Party, or (where such Party holds the Share as a result of a delegation by a Mandatory Licensee) that Mandatory Licensee, to hold a Share;

1.4.4 A Retiring Shareholder shall pay up all amounts which remain unpaid on any Share held by it (and BSCCo may give notice to that effect). The Retiring Shareholder will transfer its Shares at par to the BSCCo Nominee who will hold the Shares. The BSCCo Nominee will be selected by the Directors. All costs and expenses of such transfer shall be for the account of the Retiring Shareholder. BSCCo shall (unless directed otherwise by the Authority) ensure that the BSCCo Nominee is registered as the holder of any Shares transferred to it under this paragraph.

1.4.5 If a Retiring Shareholder fails or refuses to transfer any Shares in accordance with its obligations under paragraph 1.4.4, the Retiring Shareholder irrevocably appoints any Director as its agent to execute and deliver a transfer of the Shares from the Retiring Shareholder to the BSCCo Nominee. BSCCo may accept the consideration for the transfer (subject to the Retiring Shareholder paying-up all amounts which remain unpaid on any Share) and hold it on trust for the Retiring Shareholder, which acceptance shall be a good discharge to the BSCCo Nominee, and may set off such amounts against the costs and expenses of the transfer. The Directors shall cause the BSCCo Nominee to be registered as the holder of such Share and, following the registration of the transfer, the validity of the proceedings shall not be questioned by BSCCo, any Party or any Shareholder.

1.4.6 The BSCCo Nominee referred to in paragraphs 1.4.4 and 1.4.5 shall hold Shares transferred to it until such time as it is directed by the Directors to transfer them (or some of them) in accordance with paragraph 1.3 and for such period (and only for such period) as the BSCCo Nominee holds any Shares, all rights attaching to the Share shall be suspended, including the matters referred to in paragraph 1.5.4.

1.5 Further undertakings of Shareholders

1.5.1 No Shareholder shall:

(a) pledge, mortgage (whether by way of fixed or floating charge) or otherwise encumber its legal or beneficial interest in its Shares; or

(d) agree, whether or not subject to any condition precedent or subsequent, to do any of the foregoing.

1.5.2 Each Shareholder acknowledges and agrees that BSCCo will have complete independence from its Shareholders in its operations and undertakes not to take any action which obstructs or interferes with, or seeks to obstruct or interfere with, the carrying out of by BSCCo of its role, powers, functions and activities under the Code provided that this paragraph shall not:

(a) restrict the exercise of Shareholder rights in order to comply with the requirements of this Annex; or

(b) restrict the exercise by a Party that is also a Shareholder of its rights in its capacity as a Party under the Code.

1.5.3 The Shareholders shall at all times exercise their rights, and take all available steps, as Shareholders, and shall only exercise any such right or take any such step, so as to give effect to the provisions of the Code as to the matters set out in paragraph 1.5.4.

(a) the amendment of the Articles of Association of BSCCo so that they are in any modified form from time to time pursuant to Section C2.1.2;

(d) any other act of or in relation to BSCCo which can, or under any Legal Requirement must, be done by a vote or resolution or other assent of the Shareholders.

(a) the convening of an annual or extraordinary general meeting of BSCCo;

(b) the waiving of notice or agreeing to short notice of such meeting;

1.6 No obligation to finance

1.6.1 The Parties acknowledge that BSCCo has been established as a company limited by shares and consequently, in accordance with Section 3 of the Companies Act 2006, the liability of each Shareholder, in its capacity as Shareholder, is limited to the amount, if any, unpaid on the Shares held by that Shareholder.

1.6.2 Without prejudice to the obligations on Parties generally under Section D, the Shareholders, in their capacity as Shareholders, shall have no liability or obligation to provide any finance or financial support to BSCCo or any Subsidiary of BSCCo and shall have no liability or obligation to other Parties as Shareholders.

1.7 Winding-up of BSCCo

1.7.1 The principles which are to apply in the event of the winding-up of BSCCo are that, so far as is lawful:

(a) the assets and resources of BSCCo should be transferred (for value or otherwise as may be lawful) to any successor under the Code to BSCCo;

(b) subject to paragraph (c), and after payment or settlement of all liabilities of BSCCo, any amount which would otherwise be available for distribution to the Shareholders should be paid to Trading Parties in their Annual Funding Shares or such other proportions as the Authority may decide;

(c) the Shareholders shall be entitled to be paid out of any such amount as is referred to in paragraph (b) the amount of any taxation for which they may be liable in connection with such winding up and/or the giving effect to such principles;

and BSCCo, the Shareholders and the other Parties shall take such steps as are available and lawful to secure that these principles are given effect.

1.8 Legal Requirements relating to Shareholders

1.8.1 This paragraph 1.8 applies in the event that:

(a) any steps taken by BSCCo or a Subsidiary of BSCCo (or which might be taken); and/or

(b) any steps that a Shareholder is required to take as a consequence of being a Shareholder (including any step required under paragraph 1.3.4 or 1.5.3 of this Annex),

results in, or could result in, that Shareholder, or an Affiliate of that Shareholder, being in breach of, or being required to take action under or make a payment under, or incurring a liability under, a Legal Requirement (or being or doing so in the absence of a notification to or approval of a Competent Authority) (any such step being a "relevant step" for the purposes of this paragraph 1.8).

1.8.2 Such Shareholder may from time to time notify to BSCCo particular Legal Requirements, applying to that Shareholder or its Affiliates, which the Shareholder reasonably considers may fall within paragraph 1.8.1, provided that the Shareholder shall at the same time provide such details of such Legal Requirement as are reasonably necessary to enable BSCCo to determine whether any step which it might take, or which a Shareholder might be required to take, would be a relevant step in relation to such Legal Requirement.

1.8.3 Where the Shareholder has for the time being notified BSCCo of a particular Legal Requirement pursuant to paragraph 1.8.2, BSCCo will take all reasonable measures to ensure that it and its Subsidiaries do not take any relevant step, or require the Shareholder to take a relevant step, in relation to that Legal Requirement unless:

(a) BSCCo has first notified and consulted with the Shareholder in relation to such step, and

(b) either the Shareholder has approved the taking of such step or BSCCo is required to take such step for the purposes of discharging its functions and responsibilities under the Code (but subject always to any Code Modification made following a proposal by any person entitled to do so) or in order to comply with a Legal Requirement.

1.8.4 For the purposes of this paragraph 1.8:

(a) Legal Requirement shall be construed:

(i) as including a requirement of any stock exchange in any country or of the Panel on Takeovers and Mergers or any body in any country having equivalent functions to those of that panel where compliance with the requirements of such body is customary; and

(ii) in accordance with paragraph (b);

(b) Competent Authority shall be construed as though the reference to the United Kingdom in the definition thereof included any country or state to the jurisdiction of which the Shareholder or any of its Affiliates is subject by reason of having a presence in such country or state.

1.9 Taxation and other payments

1.9.1 BSCCo covenants to pay to each Shareholder an amount equal to any liability to corporation tax on chargeable gains for which BSCCo or any of its Subsidiaries is primarily liable for which that Shareholder or any of its Subsidiaries is liable for which any of them would not have been liable but for being treated as being or having been a member of the same group as BSCCo or any of its Subsidiaries for the purposes of corporation tax on chargeable gains.

1.9.2 Each Shareholder covenants to pay to BSCCo an amount equal to any liability for corporation tax on chargeable gains for which that Shareholder or any of its Subsidiaries is primarily liable for which BSCCo or any of its Subsidiaries is liable but for which it would not have been liable but for being treated as being or having been a member of the same group as that Shareholder for the purposes of corporation tax on chargeable gains.

1.10 Conflict with Articles

1.10.1 In the event of any ambiguity created by or discrepancy between the provisions of this Annex and the Articles, it is the intention that the provisions of this Annex shall prevail and accordingly the Shareholders shall exercise all voting and other rights and powers available to them so as to give effect to the provisions of this Annex and shall further, if necessary, procure any required amendment to the Articles to ensure any such ambiguity or discrepancy is resolved.

1.11 Further Assurance

1.11.1 Each Shareholder shall co-operate with the other Shareholders and execute and deliver to the other Shareholders such other instruments and documents and take such other actions as may be reasonably requested from time to time in order to give effect to this Annex.

1.12 Expenses

1.1.4 Nothing in this Section D applies in relation to Trading Charges.

1.2 Funding Shares

(e) subject to paragraphs 1.2.2, 1.2.3 and 1.2.4, the "Annual Funding Share" of a Trading Party is the sum of its General Funding Shares for the twelve consecutive months ending with and including that month, divided by the sum for all Trading Parties of their General Funding Shares for such twelve months;

(f) "Funding Shares" means Main Funding Shares, SVA (Production) Funding Shares, General Funding Shares, Annual Funding Shares and (where applicable in accordance with paragraph 1.3) Default Funding Shares.

1.2.2 A reference in any provision of the Code to the General Funding Share or Annual Funding Share (in relation to any month) of a Trading Party on a "default basis", in the context of one or more other Trading Parties being in default of a payment obligation under the Code, is to such General Funding Shares or Annual Funding Shares determined, as provided in Part 4 of Annex D-1, so as to disregard the participation of the Trading Party(ies) in default.

1.2.3 Subject to paragraph 1.2.4, for the purposes of paragraph 1.2.1(e) a Trading Party shall be treated as having a General Funding Share of zero for any month for which no General Funding Share was determined for that Trading Party.

1.2.4 In relation to any month which is less than twelve months after the Go-live Date, the number of months referred to in paragraph 1.2.1(e) shall be the number of whole months from the Go-live Date to and including that month.

1.3 Default Funding Shares

1.3.1 For the purposes of this Section D:

(a) a Trading Party is a "defaulting party" in relation to a BSC Year (a "default" BSC Year) where:

(i) the Trading Party failed to pay any amount by way of BSCCo Charges (for which that Party was liable) accruing in respect of the default BSC Year, and

(ii) such unpaid amount was recognised by BSCCo as a bad debt and included in BSC Costs pursuant to paragraph 2.1.1(a)(ii) in relation to the default BSC Year;

(b) in relation to every month in a default BSC Year (irrespective of the month in which any defaulting party failed or first failed to make payment), the "Default Funding Share" (FSD_pm) of each Trading Party which was not a defaulting party in that year is its General Funding Share determined on a default basis in relation to all defaulting parties.

1.4 Determination of Funding Shares

1.4.1 BSCCo will:

(a) determine periodically in accordance with paragraph 4 each Trading Party’s Main Funding Share, SVA (Production) Funding Share and General Funding Share, Annual Funding Share and (where applicable) Default Funding Share for each month; and

(b) notify all such Funding Shares to all Trading Parties in the statement provided under paragraph 4.5.1(b).

1.4.2 Annual Funding Shares determined in relation to any month in accordance with paragraph 4:

(a) shall be final and binding on Trading Parties, notwithstanding that (in accordance with paragraph 4.3) they are based on estimated data (used in the determination of General Funding Shares) for certain months; and

(b) shall not be subject to any subsequent adjustment or reconciliation upon actual data becoming available or upon any subsequent redetermination of General Funding Shares.

1.4.3 Each Party shall, upon request of BSCCo, provide to BSCCo any information reasonably requested by it for the purposes of determining Trading Parties' various Funding Shares.

1.4.4 So far as data derived in Volume Allocation is used in the determination of any Funding Shares:

(a) such data shall be that derived from the Initial Volume Allocation Runs for Settlement Days in the relevant month, which shall be final and binding for the purposes of such determination;

(b) no adjustment or reconciliation shall be made in respect of or by reference to any Reconciliation Volume Allocation Run or data derived therefrom, or otherwise as a result of the resolution of any Trading Dispute relating to such data.

1.4.5 If:

(a) at the time at which a Trading Party first raised a Trading Dispute in accordance with Section W, such Party notified the Panel that the Party wishes this paragraph 1.4.5 to apply; and

(b) following resolution of the Trading Dispute (or as the case may be the making of an arbitral award) and the carrying out of a Reconciliation Volume Allocation Run, the Panel in its sole discretion considers that such resolution or award amounts to an exceptional circumstance which justifies making an adjustment in respect of the Volume Allocation data used in determining Funding Shares,

then the Panel may require BSCCo to redetermine Funding Shares (for all or any particular purposes of the Code) accordingly, and to make the consequential adjustments in respect of the amounts paid or payable by Trading Parties by way of BSCCo Charges.

2.4.2 Each Party further undertakes that it will not act in any way prejudicial to such agreement, including acting on the basis of, assuming, seeking or making any application or request to any tax authority for, any conflicting treatment.

(iii) "Monthly Production-Charging SVA Costs" (MPSC_m) is 1/12 of Annual Production-Charging SVA Costs;

(e) "Monthly Default Costs" (MDC_m) is 1/12 of Annual Default Costs.

4.2 Liability in Funding Shares

4.2.1 For each month in any BSC Year, each Trading Party shall be liable to BSCCo for:

(a) its Main Funding Share for that month of the Monthly Net Main Costs;

(b) not used;

(d) its Default Funding Share of the Monthly Default Costs.

4.2.2 Amounts for which Trading Parties are liable pursuant to paragraph 4.2.1 shall be invoiced in accordance with the further provisions of this paragraph 4.

4.3 Invoicing, estimation and reconciliation

4.3.1 In relation to each month (the "invoice month") of each BSC Year, BSCCo shall determine:

(a) the amounts of:

(i) Monthly Net Main Costs,

(ii) Monthly Consumption-Charging Net SVA Costs,

(iii) Monthly Production-Charging SVA Costs,

(iv) Monthly Default Costs (if any)

for the invoice month and each preceding month in that year, consistent with the prevailing Annual Budget, and based on its prevailing estimate of Annual Net Main Costs, Annual Production-Charging SVA Costs and Annual Default Costs for the year;

(b) for each Trading Party, in relation to the invoice month and each preceding month in that BSC Year:

(i) the Main Funding Shares, SVA (Production) Funding Shares and (where applicable) Default Funding Shares of such Party; and

(ii) the amounts for which such Party is liable by way of Specified Charges;

(i) on the basis of paragraphs (a) and (b), the aggregate amounts for which such Party is liable in such BSC Year, up to and including the invoice month, by way of BSCCo Charges;

(ii) the aggregate amount (if any) already paid or payable by each Party by way of BSCCo Charges in such BSC Year, up to and including the month preceding the invoice month;

(iii) the amount of the difference (whether positive or negative) between the amounts in paragraphs (i) and (ii).

4.3.2 BSCCo’s determinations under paragraph 4.3.1 shall be made:

(a) as at 1000 hours on the fifteenth Business Day of the month preceding (or if BSCCo has so notified Parties, the second month preceding) the invoice month, subject to paragraph 4.5.2 (and as soon as is practicable after that time and in any event no later than the last Business Day of that month);

(b) on the basis of actual data available to it at the time referred to in paragraph (a), and otherwise on the basis of BSCCo’s estimates of the relevant data; and accordingly actual data received by BSCCo after such time will not be taken into account until the following month.

4.3.3 BSCCo shall prepare and from time to time revise, and make available to the Panel and to Parties, a statement of the principles and methods by which it makes estimates under paragraph 4.3.2(b), but it is acknowledged that such principles and methods will not be applicable in all cases, and in the absence of any such applicable principle or method BSCCo will make such estimates as appear to it to be reasonable.

4.3.4 Subject to paragraph 4.3.5, the amount to be invoiced by BSCCo to each Trading Party each month by way of BSCCo Charges shall be the amount determined pursuant to paragraph 4.3.1(c)(iii) (which amount shall be payable by or to the Trading Party according to whether it is positive or negative).

4.3.5 Where for any Trading Party in relation to any month the magnitude of the amount referred to in paragraph 4.3.4 is less than the minimum invoice amount, no amount shall be invoiced to that Party by way of BSCCo Charges in respect of that month (but without prejudice to the determinations made pursuant to paragraph 4.3.1 in the following month); and for the purposes of this Section D the "minimum invoice amount" shall be such amount as the Panel shall from time to time determine, and shall initially be five hundred pounds sterling (£500).

4.3.6 No interest shall accrue on or be taken into account in the determination of any amounts under paragraph 4.3.1 or upon reconciliation under paragraphs 4.4 or 8.

4.3.7 Notwithstanding paragraph 4.3.1, BSCCo shall apply the formula set out in Annex D-4 for the purposes of determining the amount to be invoiced each month to each Trading Party by way of BSCCo Charges, and in the event of any conflict between this paragraph 4 and that Annex, that Annex shall prevail.

4.3.8 Where upon the application of BSCCo the Panel accepts that a substantial proportion of BSC Costs are or are likely to be incurred on a significantly uneven basis over the course of a BSC Year, and the Annual Budget indicates such basis by specifying the factors (approved by the Panel) referred to in paragraph (b):

(a) for the purposes of its determinations under paragraph 4.3.1 (except pursuant to paragraph 4.4), BSCCo may, with the approval of the Panel, adjust the basis of determining Monthly Net Main Costs and Monthly Net SVA Costs, by recognising the expected profile of such expenditure in accordance with paragraph (b);

(b) such profile will be recognised by applying factors (as approved by the Panel) other than 1/12 in relation to all or certain months for the purposes of paragraph 4.1(d);

(c) BSCCo will inform Trading Parties of such factors (and the month(s) to which each such factor applies) as soon as they have been approved by the Panel; but

(d) Trading Parties' General Funding Shares shall be determined pursuant to Annex D-1 disregarding the recognition of such expected profile (and on the basis of factors of 1/12 in paragraph 4.1(d).

4.4 Reconciliation

4.4.1 In relation to each BSC Year, BSCCo shall, not later than twenty-eight days after publication of its audited accounts for that year, make a final determination and adjustment in respect of the amounts payable by each Trading Party way of BSCCo Charges.

4.4.2 Such determination and adjustment shall be made in accordance with paragraph 4.3 except that:

(a) BSCCo shall use only actual data and shall not (unless any actual data remains unavailable to it at the time of such determination) use estimated data;

(b) paragraph 4.3.4 (providing for a minimum invoiced amount) shall not apply;

(d) paragraph 4.4.8 shall also apply in respect of MHHS Implementation Management Monthly Charges.

4.4.3 BSCCo shall invoice to Trading Parties the amounts determined to be payable pursuant to paragraph 4.4.1 by way of final reconciliation and adjustment in respect of BSCCo Charges payable by Trading Parties in the relevant BSC Year.

4.4.4 Subject only to paragraph 4.4.5, BSCCo’s determination of BSCCo Charges in a BSC Year under paragraph 4.4.1 shall be final and binding, and no further adjustment shall be made (and accordingly any subsequent adjustment in respect of BSC Costs in the BSC Year shall be taken into account in the BSC Costs for the BSC Year in which such adjustment is identified and made).

4.4.5 If, after the final determination under paragraph 4.4.1, the Panel determines that there are exceptional circumstances which justify an adjustment in respect of an extraordinary error in the determination of, or in data used in the determination of, any Funding Shares under that paragraph, the Panel may in its discretion direct, and Trading Parties shall be bound by, and BSCCo shall give effect to, such adjustment in respect of BSCCo Charges (payable by and to Trading Parties) in that BSC Year as appears to the Panel to be appropriate.

4.4.6 It is acknowledged that any BSC Costs referred to in Section H1.7 may, if the Panel decides it is appropriate to do so, be apportioned (on such basis as the Panel shall so decide) over the period from the Go-live Date to the BSC Year in which they are incurred, and in such case the Panel may direct that BSCCo shall redetermine (on such basis of approximation as the Panel may approve) each Trading Party's liability for BSCCo Charges over such period, and each Trading Party shall be bound by such direction and determination and shall be liable to make adjustment payments in respect of BSCCo Charges accordingly.

4.4.7 In respect of Modification Proposal P396:

(a) for the purposes of this paragraph 4.4.7, the "P396 Reconciliation Date" shall be the later of:

(i) the day next following the date on which the Authority issued a notice of modification to the National Grid Electricity System Operator Limited in respect of Modification Proposal P396; or

(ii) the first day of the BSC Year during which the date on which the implementation of Approved Modification P396 takes place (the "P396 Implementation Date");

(b) as soon as practically possible after the P396 Implementation Date, BSCCo shall determine, in accordance with paragraph (c), an adjustment to the amounts paid to or payable by each Party by way of BSCCo Charges;

(i) the amounts already paid to or payable by each Party by way of BSCCo Charges in relation to the period commencing on the P396 Reconciliation Date and ending on day immediately prior to the P396 Implementation Date; and

(ii) the amounts that would have been payable by each Party over the same period had Modification Proposal P396 been in effect from the P396 Reconciliation Date;

(d) BSCCo shall send an invoice to Parties in respect of the reconciliation amounts determined pursuant to paragraph 4.4.7(c) (and where such amounts are not included in an invoice to be sent to Parties pursuant to paragraph 4.5.1 then, in respect of such invoice, the provisions of paragraph 4.5 shall apply mutatis mutandis);

(e) subject to paragraph 4.4.5, BSCCo’s determination of the reconciliation amounts shall be final and binding.

4.4.8 As part of the reconciliation determined under this paragraph 4.4, BSCCo shall:

recalculate the charge rate for the MHHS Implementation Management Monthly Charge set for the previous BSC Year but, for the purposes of such recalculation, shall use the actual MHHS Programme Costs incurred by BSCCo during that BSC Year; and
report, to the Panel, the revised charge rate for the MHHS Implementation Management Monthly Charge together with the outcome of the reconciliation calculated under paragraph 4.4.8(a).

4.5 Invoicing

4.5.1 In respect of each month, not less than five Business Days after making its determination for that month under paragraph 4.3.2, BSCCo shall send to each Trading Party:

(a) an invoice in respect of the amounts accruing in respect of BSCCo Charges in the following month (or where paragraph 4.5.2 applies, accruing in the relevant prior month), setting out:

(i) the net amount determined as payable by or to the Trading Party in pursuant to paragraph 4.3.1(c)(iii);

(ii) applicable VAT in respect of supplies to which the invoice relates;

(iii) the invoice due date in accordance with paragraph 4.5.3;

(b) a statement showing the basis of calculation (pursuant to paragraph 4.3) of the amounts under paragraph (a).

4.5.2 Where BSCCo has sufficient working capital available to it (pursuant to any permitted borrowing in accordance with Section C3.4.3(a)), BSCCo may decide, after consultation with the Panel, to invoice BSCCo Charges (to all Parties) up to three months in arrears.

4.5.3 Following the final determination by BSCCo in respect of the preceding BSC Year in accordance with paragraph 4.4, BSCCo shall send to each Trading Party an invoice and statement setting out the matters specified in paragraph 4.5.1.

4.5.4 The due date of each invoice for BSCCo Charges shall be the tenth Business Day after the date of receipt of the invoice.

4.5.5 Where the right of a Defaulting Party to receive payment has been suspended under Section H3.2.2(h):

(a) no amount becoming due and payable (pursuant to this Section D or Annex S-1) to such Defaulting Party shall be paid by BSCCo to such Defaulting Party (or to any person to whom the Defaulting Party may have assigned or transferred any of its rights pursuant to the Code);

(b) no interest shall run or be payable in respect of any such unpaid amount;

(c) BSCCo (but not the Defaulting Party) may set off, from and against such unpaid amount, any amount subsequently becoming payable (pursuant to this Section D or Annex S-1) by such Defaulting Party.

(a) that the Performance Assurance Board may delegate to BSCCo the invoicing and administration of payment of Supplier charges (and any associated amounts in respect of VAT) on behalf of Suppliers and qualifying Trading Parties under Annex S-1,

(b) in such case, that BSCCo may combine the invoicing and administration of payment of BSCCo Charges (on its own behalf) and Supplier charges under Annex S-1, and may submit a single invoice to each Party and require and make or receive a single payment in respect such amounts; and subject to paragraph 4.6.2 each Party authorises BSCCo to do so, notwithstanding any contrary provisions as to the basis (including any express or implied trust) on which such amounts are to be held by the Performance Assurance Board pursuant to Annex S-1.

4.6.2 Where pursuant to paragraph 4.6.1:

(a) BSCCo receives any amount which includes any payment from any Supplier of any amount under Annex S-1, and

(b) BSCCo does not on the same day make payment of the corresponding amount payable to the qualifying Trading Parties entitled thereto pursuant to Annex S-1 (or has not given credit for such corresponding amount in determining the net amount invoiced pursuant to paragraph 4.6.1 to such qualifying Trading Parties)

then BSCCo shall promptly upon receipt of such amount segregate that part of such amount which is referable to the payment from the Supplier pursuant to Annex S-1 into an account separate from that in which amounts paid in respect of BSCCo Charges are held (but without prejudice to paragraph 4.1.12 of Annex S-1).

+ ½ * {^CΣ⁺_(non-I) (QCE_iaj) + ^CΣ^-_(non-I) (-QCE_iaj)} / Σ_p {^CΣ⁺ _(non-I) (QCE_iaj) + ^CΣ^-_(non-I) (-QCE_iaj)}

where:

^PΣ⁺_(non-I)represents, for the Production Energy Account a belonging to Party p, a sum over each Settlement Period in month m and each BM Unit that is not an Interconnector BM Unit, where the Trading Unit to which the BM Unit belongs is delivering in the Settlement Period j.

^PΣ_(non-I)represents, for the Production Energy Account a belonging to Party p, a sum over each Settlement Period in month m and each BM Unit that is not an Interconnector BM Unit, where the Trading Unit to which the BM Unit belongs is offtaking in the Settlement Period j.

^CΣ⁺_(non-I)represents, for the Consumption Energy Account a belonging to Party p, a sum over each Settlement Period in month m and each BM Unit that is not an Interconnector BM Unit, where the Trading Unit to which the BM Unit belongs is delivering in the Settlement Period j.

^CΣ^-_(non-I)represents, for the Consumption Energy Account a belonging to Party p, a sum over each Settlement Period in month m and each BM Unit that is not an Interconnector BM Unit, where the Trading Unit to which the BM Unit belongs is offtaking in the Settlement Period j.

where:

TSC_pm = the aggregate amount payable by a Trading Party by way of Specified BSC Charges in respect of month m;

MNMC_m = Monthly Net Main Costs relating to month m

FSM_pm = Main Funding Share for Trading Party p relating to month m

MPSC_m= Monthly Production-Charging SVA Costs relating to month m

FSPS_pm = SVA (Production) Funding Share for Trading Party p relating to month m

MDC_m = Monthly Default Costs relating to month m

FSD_pm = Default Funding Share for Trading Party p relating to month m

Σ_m = the sum over all of the months of the BSC Year up to and including month m;

Σ_m-1= the sum over all of the months of the BSC Year up to and including the month preceding month m;

Σ_m(1) = the number of months of the BSC Year up to and including month m;

1.2 In accordance with Section D4.3 the data used for the calculation will be estimated data where actual data is not available; and values of monthly BSC Costs (of different types) will be determined in accordance with Section D4.3.8 where that paragraph applies.

2. Reconciliation

2.1 For the purposes of the reconciliation pursuant to Section D4.4 the amount (P_p) payable by each Trading Party p by way of final reconciliation and adjustment is determined as follows:

P_p = Σ_m(TSC_pm) +Σ_m (MNMC_m) * Σ_m(FSM_pm) / 12 +Σ_m(MPSC_m) * Σ_m(FSPS_pm) / 12 +Σ_m(MDC_m) * Σ_m(FSD_pm) / 12 - Σ_m(P_pm)

where

Σ_m = the sum over all of the months of the BSC Year

all other terms have the meanings in paragraph 1.

2.2 In accordance with Section D4.4.2 the data used for the calculation will be actual data (unless not then available); and Section D4.3.8 shall not apply in relation to the determination of values of monthly BSC Costs (of different types).

1.6 Interpretation of Code

1.6.1 The Code sets out or describes certain functions of BSC Agents as obligations of those Agents (to be reflected in the terms of BSC Agent Contracts in accordance with paragraph 2.1.3), but it is acknowledged that (as BSC Agents are not party to the Framework Agreement) the Code does not of itself directly impose obligations on any person appointed as BSC Agent.

1.6.2 The failure of a BSC Agent to perform and discharge any of its functions as provided for in the Code shall not affect the rights and obligations of the Parties in respect of Settlement under the Code (so far as such rights and obligations are capable of being construed and determined notwithstanding such failure), but subject to the express provisions of the Code as to:

(a) the effect of Volume Allocation Runs and Settlement Runs (as provided in Section U2.6);

(b) the resolution of Trading Disputes;

(c) the consequences of an incorrect determination that a Trading Party is in Credit Default (as provided in Section M); and

2.1 General

2.1.1 It shall be the responsibility of BSCCo to ensure that there is at all times a person appointed as BSC Agent for the purposes of providing all of the services under each BSC Service Description.

2.1.2 BSCCo shall, subject to and in accordance with the further provisions of this Section E:

(a) select the person to be appointed as each BSC Agent;

(b) enter into (or accept an assignment or novation of) a contract with each person appointed as a BSC Agent;

(g) upon expiry or termination of a BSC Agent Contract, extend or renew the contract or (in accordance with paragraphs (a) and (b)) select and appoint a different person as the BSC Agent.

2.1.3 Without prejudice to anything contained in a BSC Service Description, (and subject to the application of the change management procedures in that contract upon any Code Modification or change to a Code Subsidiary Document, and subject to paragraph 2.1.4):

(a) subject to paragraph 1.5, that the BSC Agent undertake all of the functions and responsibilities described:

(i) in the Code, and

(ii) any Code Subsidiary Document

as being functions and responsibilities of that BSC Agent (or which have been allocated to that BSC Agent pursuant to paragraphs 1.2.6 and 1.5);

(b) each BSC Agent Contract shall require the BSC Agent to:

(i) undertake the functions and responsibilities described in the Code as being functions and responsibilities applicable to BSC Agents generally; and

(ii) to the extent (if any) to which the Code provides any standard for or requirement as to the quality of such performance, that the BSC Agent performs its functions and responsibilities in accordance with such standard or requirement.

2.1.4 If a person proposed to be appointed as BSC Agent does not agree to enter into a BSC Agent Contract whose terms comply with paragraph 2.1.3, or seeks to introduce into a proposed BSC Agent Contract a term which in BSCCo’s reasonable opinion would qualify any such standard or requirement as is referred to in paragraph 2.1.3(b)(ii):

(a) BSCCo shall not enter into such BSC Agent Contract with such person without approval of the Panel;

(b) the Panel shall consult with Parties if and to the extent it considers appropriate (having regard to the significance of the matter to which the prospective BSC Agent objects) before giving such approval; and the Panel shall, where it considers it appropriate, deal with the matter as a modification to the relevant BSC Service Description;

(c) the Panel shall not in any event give such approval where the prospective BSC Agent objects to any material term of the proposed BSC Agent Contract included to comply with paragraph 2.1.3(a)(i).

2.1.5 Subject to paragraph 1.2.3, a single BSC Agent Contract may relate to services to be provided (by the person entering into such contract) in the capacity of more than one BSC Agent.

2.1.6 In accordance with Section C7.1.1, a BSC Agent Contract may be entered into by a Subsidiary of BSCCo (other than the BSC Clearer, save that this shall not prevent the BSC Clearer from being a party to a contract with the FAA).

2.1.7 Not used.

2.1.8 Nothing in this paragraph 2.1 requires that a BSC Agent Contract should prevent the relevant BSC Agent from sub-contracting the provision of any of the services to be provided thereunder, but without prejudice to paragraph 2.3.4.

2.2.2 Without prejudice to the generality of paragraph 2.1.2(c), BSCCo shall:

(a) if under a BSC Service Description the BSC Agent may be required to provide on an ad-hoc or non-routine basis any service to or for the benefit of a Party individually (rather than Parties or any class of Parties collectively), order the provision of that service in accordance with the reasonable requests of any such Party but subject to that Party's compliance with any relevant procedural requirements, and account for the costs of ordering that service in accordance with any applicable provisions of Section D;

(b) where it is aware of circumstances in which such right or remedy has arisen, but only with the approval of the Panel and subject to recovery (from the individual Party or otherwise) of its costs of so doing on such basis as the Panel may decide, take reasonable steps to enforce any provision of a BSC Agent Contract which provides any right or remedy for or for the benefit of a Party individually (rather than Parties or any class of Parties collectively), keep that Party reasonably informed as to the steps being taken for such enforcement, and account to that Party for any amount recovered pursuant to such enforcement.

2.2.3 Nothing in paragraph 2.2.2 shall prevent a Party from ordering the provision of any service (under a BSC Agent Contract) directly from a BSC Agent in a case in which BSCCo has with the Panel's approval made arrangements with the BSC Agent under which:

(a) Parties (or Parties of any class) may directly order such services; and

(b) all of the charges of the BSC Agent referable to the provision of such service are to be met directly by (or charged as Specified BSC Charges to) the Party ordering the service.

2.2.4 BSCCo shall consult with the Panel before:

(a) commencing any proceedings or arbitration against a BSC Agent under a BSC Agent Contract, or

(b) agreeing a settlement in respect of any proceedings or arbitration (whether brought by BSCCo or the BSC Agent) or any claim by BSCCo or the BSC Agent which might otherwise lead to such proceedings or arbitration, or

and where the amount subject to such proceedings or arbitration or of such claim exceeds (or in BSCCo's reasonable opinion is likely to exceed) such threshold amount as the Panel may from time to time specify for the purposes of this paragraph 2.2.4, BSCCo shall obtain the approval of the Panel before doing any of the foregoing.

2.2.5 BSCCo shall:

(a) inform the Panel of any proceedings or arbitration commenced or threatened by a BSC Agent against BSCCo; and

(b) without prejudice to paragraph 2.2.4, keep the Panel informed as to the progress of and any settlement of any proceedings or arbitration with a BSC Agent (whether commenced by BSCCo or the BSC Agent);

(c) inform the Panel of any substantial and abnormal occurrences in or circumstances affecting the performance of any BSC Agent Contract.

2.2.6 BSCCo shall:

(a) in discussion with the Panel, establish and from time to time amend arrangements for reporting periodically to the Panel in respect of the management of each BSC Agent Contract and the performance of each BSC Agent thereunder;

(b) report to the Panel in accordance with such procedures and arrangements.

2.3 Contract Principles

2.3.1 BSCCo shall, in consultation with the Panel or any Panel Committee established for the purpose, establish and from time to time review and amend, a statement of the principles ("Contract Principles") by which BSCCo is to be guided in setting or agreeing the terms of BSC Agent Contracts or any amendments thereto.

2.3.2 Particular Contract Principles may apply in relation to one, some or all of the contracts entered or to be entered into with BSC Agents.

2.3.3 The Contract Principles shall be consistent with the objectives in Section B1.2.1, with Good Industry Practice and with the further requirements of the Code, and shall include principles as to at least the following matters:

(a) consistent with paragraph 2.4.1(a), the capacity of BSCCo (whether as principal, trustee or agent for the benefit of all or certain Parties, or otherwise) in entering into the contract, and the extent to which the Contracts (Rights of Third Parties) Act 1999 is to apply for the benefit of all or certain Parties;

(b) the principles and methods of pricing of services under the contract;

(d) the extent to which the BSC Agent is to be relieved from liability for breach resulting from circumstances beyond its reasonable control;

(e) the extent to which the terms of the contract, and information concerning the BSC Agent's performance, may be freely disclosed by BSCCo to Parties;

(f) the ownership of Intellectual Property Rights in materials produced by the BSC Agent pursuant to the contract;

(g) where a single person acts in the capacity of more than one BSC Agent, the extent to which the processes and systems employed by that person in each capacity are to be separated or capable of separation from each other;

(h) principles to apply where the BSC Agent sub-contracts performance of its obligations, and the extent (if any) to which the contract should restrict the ability of the BSC Agent to do so.

2.3.4 In setting or agreeing the terms of BSC Agent Contracts or any amendments thereto, BSCCo will seek to apply the applicable Contract Principles, and will obtain the consent of the Panel before knowingly departing in any material respect from the applicable Contract Principles.

2.4 Contract requirements

2.4.1 Each BSC Agent Contract shall contain terms which:

(a) give effect to the principle that Trading Parties should have the benefit of the main obligations of the BSC Agent under the contract, whether:

(i) by express provision to that effect in the contract, in which case the contract shall not contain provisions which would restrict the application of the Contracts (Rights of Third Parties) Act 1999 in relation to the relevant terms of the contract, but subject to paragraph 3.2.4;

(ii) by virtue of BSCCo entering into such contract (inter alia) as trustee for or agent for the benefit of Trading Parties;

or otherwise, save that, following BSCCo’s request to the Panel, the Panel may determine in its absolute discretion to approve the exclusion of the provisions of paragraph 2.4.1(a) (i) and (ii) above. The Panel:

(iii) shall, where it deems necessary, undertake a prior consultation with Parties; and

(iv) shall, where it has given an approval under this paragraph, determine the extent to which paragraphs 3.3.1, 3.3.2 and 3.3.4 should apply in respect of that BSC Agent and BSC Agent Contract, and may exclude any part of those paragraphs as a condition of its approval;

(b) provide that such contract may be assigned or novated, without consent of the BSC Agent, to any company acting as successor to BSCCo (and having no lesser financial standing than BSCCo) for the purposes of the Code;

(c) provide that the BSC Agent shall not make claims under or in respect of breaches of the BSC Agent Contract against any Party other than BSCCo; and

(d) reflect the requirement in paragraph 3.2.1;

(e) where such contract includes the supply of services in support of Permissible Activities pursuant to Sections C10 or C11:

(i) prevent the BSC Agent from terminating any part of a BSC Agent Contract that relates to the performance of BSC Agent services as a result solely of any breach by BSCCo of provisions relating to the supply of services by the BSC Agent in respect of Permissible Activities; and

(ii) to the fullest extent permitted by law, restrict BSCCo’s liability to the BSC Agent for any claim in damages or any other claim of a financial nature relating solely to the supply of services by the BSC Agent in support of Permissible Activities to the amounts payable under that BSC Agent Contract for those services.

2.5 Scottish Trading Arrangements

2.5.1 This paragraph 2.5 applies in relation to any BSC Agent Contract where under the terms of such contract the BSC Agent grants any licence to or otherwise confers any rights on BSCCo (for itself or for the benefit of Parties or otherwise) in respect of Intellectual Property Rights ("relevant IPRs") of the BSC Agent.

2.5.2 The BSC Agent Contract shall provide that, upon the request of the Authority, the BSC Agent will grant an equivalent licence or confer equivalent rights, or that BSCCo may grant a sub-licence or otherwise confer equivalent rights, in or to the relevant IPRs, to a designated person (for itself or for the benefit of Scottish Trading Parties) for the approved purposes in Scotland, on terms (as to payment, duration and otherwise) approved by the Authority.

2.5.3 For the purposes of paragraph 2.5.2:

(a) "Scottish Trading Parties" are persons who participate (in capacities equivalent to the capacity of any Party or class of Party under the Code) in any such arrangements as are described in Section F2.12;

(b) a designated person is a person designated by the Authority as fulfilling, in relation to such arrangements, a role equivalent to that of the BSC Agent or BSCCo;

(c) approved purposes are purposes in relation to such arrangements equivalent to the purposes for which the relevant IPRs are used in connection with the arrangements provided for in the Code.

2.6 Termination of BSC Agent Contracts

2.6.1 If BSCCo proposes:

(a) to exercise any right or take any other steps to terminate a BSC Agent Contract before its expiry;

(b) where BSCCo is aware that any such right has arisen, to waive such right;

(d) not, upon the expiry of a BSC Agent Contract, to extend or renew the contract

BSCCo shall so notify the Panel, and provide an explanation of its reasons for its proposal.

2.6.2 Where the exercise of a right or the taking of steps to terminate a BSC Agent Contract would, or (in BSCCo’s view, after taking legal advice) might, result in BSCCo being liable:

(a) to pay any amount (by way of fixed compensation or damages, or increases in fees or charges, or otherwise) which would not have been payable but for the exercise of such right or the taking of such steps, and/or

(b) to pay or continue to pay fees, charges or other amounts under the contract in respect of any period after the effective cessation of the provision of services thereunder

in an aggregate amount exceeding such threshold amount as the Panel may from time to time specify for the purposes of this paragraph 2.6.2, BSCCo shall not exercise such right or take such steps without the approval of the Panel.

2.7 Appointment of BSC Agents

2.7.1 Before commencing the procurement of a BSC Agent Contract, BSCCo will prepare, in discussion with the Panel, and obtain the Panel’s approval of a statement ("Procurement Approach Statement") of the approach to be adopted by BSCCo in the procurement and the criteria (consistent with the applicable Contract Principles) to be applied in competitively selecting the person to whom the contract will be awarded.

2.7.2 The Panel may (and if BSCCo so wishes, will) establish as a Panel Committee, or appoint a Panel Member as an observer, and set terms of reference (consistent with this paragraph 2.7) for, a committee ("Procurement Committee") or observer ("Procurement Observer") to advise BSCCo in connection with the conduct of the procurement and the award of the contract.

2.7.3 BSCCo shall:

(a) not vary the Procurement Approach without the approval of the Panel;

(b) conduct the procurement in accordance with the Procurement Approach Statement, and in particular award the contract in accordance with the criteria in the statement;

(c) where the Panel has established a Procurement Committee or appointed an Procurement Observer, keep the committee or observer informed of the conduct and progress of the procurement (generally and by reference to the Procurement Approach Statement), and consult with and seek the advice of the committee or observer, at intervals (including before and awarding the contract) and otherwise in accordance with the committee’s or observer’s terms of reference; and

(d) report to the Panel and (if appointed) Procurement Committee in respect of the outcome of the procurement and the award of the contract.

2.7.4 Without prejudice to any Legal Requirement, BSCCo shall not enter into a BSC Agent Contract except in compliance with this paragraph 2.7.

2.7.5 It is acknowledged that:

(a) pursuant to its obligations under Section C12.12, BSCCo appointed service providers to build new SVAA BSC Agent Systems that will, as part of MHHS Implementation transition activities, replace the legacy SVAA BSC Agent System (the "relevant service providers");

(b) it will reduce the risk to MHHS Implementation for the relevant service providers to deliver, during the MHHS Implementation transition period, the SVAA BSC Agent Services that have been implemented pursuant to MHHS Implementation (the "new SVAA BSC Agent Services"); and

(c) accordingly, and notwithstanding the provisions of this paragraph 2.7, it would be beneficial for the BSC Agent Contracts relating to new SVAA BSC Agent Services to be awarded to the relevant service providers.

2.7.6 Pursuant to paragraph 2.7.5, BSCCo may, with the prior approval of the Panel, directly award (without a competitive procurement) the initial BSC Agent Contracts relating to the new SVAA BSC Agent Services provided that such BSC Agent Contracts shall have a duration of no longer than 24 months following the completion of the MHHS Implementation transition (described as "M15" in the MHHS Implementation Timetable).

3. RELATIONSHIP BETWEEN PARTIES, BSCCO AND BSC AGENTS

3.1 General

3.1.1 The provisions of this paragraph 3 apply, inter alia, and the Parties agree that such provisions are desirable and appropriate, for the purposes of enabling BSCCo to conclude contracts with BSC Agents on reasonable terms and on an efficient basis, and ensuring that such contracts can be managed and enforced by BSCCo on a co-ordinated basis and in the interests of Parties collectively.

3.2 Status of BSC Agents

3.2.1 Unless expressly otherwise provided in the Code, a BSC Agent shall not, and BSCCo shall not authorise a BSC Agent to, act as agent for or make any commitment or incur any liability binding on any Party.

3.2.2 The rights and obligations of a BSC Agent shall be set out in the relevant BSC Agent Contract and nothing in the Code or any Code Subsidiary Document shall confer any rights or entitlements on any BSC Agent.

3.2.3 Without prejudice to the generality of Section H9.4, the Parties (including BSCCo and the BSC Clearer) do not intend:

(a) that any BSC Agent (or any agent, contractor or servant of a BSC Agent) shall have any rights, benefits, entitlements or privileges under the Code or any Code Subsidiary Document; and nothing in the Code or any Code Subsidiary Document shall be construed as conferring or purporting to confer any such right, benefit, entitlement or privilege on any such person; or

(b) that any term of the Code or any Code Subsidiary Document shall be enforceable by any BSC Agent (or any agent, contractor or servant of a BSC Agent) solely by virtue of the Contracts (Rights of Third Parties) Act 1999.

3.2.4 Each Party agrees that, in any case where by virtue of the Contracts (Rights of Third Parties) Act 1999 any term of a BSC Agent Contract is enforceable by or for the benefit of that Party, the consent of such Party shall not be required (and the BSC Agent Contract may provide that such consent is not required) to an amendment, variation or rescission of that BSC Agent Contract.

3.3 Role of BSCCo in contracting with BSC Agents

3.3.1 Where, whether by virtue of the application of the Contracts (Rights of Third Parties) Act 1999, or of BSCCo being party to any BSC Agent Contract as trustee for any Parties or agent (as to the benefit of such contract) for any Parties, or otherwise, any Party or Parties have any right, claim or entitlement against a BSC Agent pursuant to or in relation to any BSC Agent Contract:

(a) each Party hereby appoints and authorises BSCCo to act as its exclusive agent for the purposes of enforcing all rights, claims or entitlements which such Party may have pursuant to or in relation to any BSC Agent Contract, and agrees that BSCCo shall exclusively have the conduct of any proceedings in connection therewith, but subject to paragraphs 2.2.2(b) and 2.2.4;

(b) each Party agrees and undertakes with BSCCo and each other Party, and authorises BSCCo to commit as its agent and on its behalf to the BSC Agent, that such Party will not itself enforce or seek to enforce or take any action with a view to the enforcement of any such rights, claims or entitlements.

3.3.2 Each Party agrees and undertakes that BSCCo may contract with a BSC Agent on the basis that such Party waives and will not make or seek to enforce any claim in tort (including negligence, but not including any claim for fraud or in respect of liability for death or personal injury resulting from the BSC Agent's negligence) against any BSC Agent in relation to any BSC Agent Contract or any act or omission of the BSC Agent pursuant to or in relation to the BSC Agent Contract; provided that (without prejudice to paragraph 3.3.1) this shall not limit any such claim of a Party in a case in which a BSC Agent Contract is not made on such basis.

3.3.3 Where, under any provision of the Code, any Party or Parties expressly agree or undertake:

(a) to confer any permission, consent, approval, licence or right upon any BSC Agent, including without limitation in relation to access to or inspection of premises or Plant or Apparatus, or access to or the provision, use, copying or disclosure of any data, document or information; or

(b) (in accordance with paragraph 3.3.2 or pursuant to any other provision of the Code) to waive or release any BSC Agent from any possible liability (in tort including negligence or otherwise) to or claim by that Party or Parties

then BSCCo may confer, and is hereby authorised to act as agent of and on behalf of that Party or Parties in entering into the BSC Agent Contract for the purposes of conferring (subject to the express provisions of the Code in relation thereto) that permission, consent, approval, licence or right or waiver or release upon the BSC Agent (but in relation to paragraph (a), only for the purposes contemplated by the Code and subject to any restrictions or procedures provided for in or under the Code in relation thereto).

3.3.4 Each Party acknowledges that BSCCo may agree to indemnify a BSC Agent against any breach by the Party of its agreements and undertakings in paragraphs 3.3.1(b), 3.3.2 and 3.3.3; and each Party shall indemnify BSCCo in respect of any loss, liability, damages, costs (including legal costs), expenses, claims and proceedings which BSCCo may suffer or reasonably incur (pursuant to such indemnity or otherwise) by reason of any breach by that Party of its agreements and undertakings in paragraphs 3.3.1(b), 3.3.2 and 3.3.3.

3.3.5 Without prejudice to paragraph 3.3.1, but subject to the provisions of this Section E, where BSCCo is party to a BSC Agent Contract as agent for any Parties, BSCCo is hereby authorised by each Party as its exclusive agent to exercise any right, take any step and do any other thing pursuant to such BSC Agent Contract necessary or in BSCCo's opinion appropriate for the purposes of carrying out its functions (in accordance with this Section E) in respect of such BSC Agent Contract; provided that BSCCo is not thereby authorised to make any commitment or incur any liability on behalf of and in the name of such Party except with the Party's consent or in accordance with any express provision of the Code.

3.3.6 The authorities (to act as agent on behalf of Parties) conferred on BSCCo in this paragraph 3.3 are unconditional and irrevocable.

3.3.7 Without prejudice to paragraph 2.2.2(b), where BSCCo obtains or recovers any amount by way of damages or otherwise from a BSC Agent in respect of a breach of the BSC Agent Contract, and the Panel (on the application of any Party or otherwise) determines that it would be inequitable for all Trading Parties to benefit (by reason of such amount being applied to reduce BSC Costs in accordance with Section D4.1.1(a)(ii)) therefrom in their Main Funding Shares, the Panel may direct that such amount shall be applied in payment to Parties or particular Parties in such proportions as the Panel may determine, and BSCCo shall make such adjustments (in respect of BSCCo Charges or otherwise, and including where necessary not applying such amount to reduce BSC Costs) as shall be appropriate to give effect to the Panel's determination.

(a) assigns fully, irrevocably and unconditionally any and all present and future rights, IPRs or moral rights it may have in such proposal (as regards use or application in Great Britain and Offshore) to BSCCo and each Proposer acknowledges and agrees that any such rights, IPRs and moral rights shall vest in BSCCo unconditionally; and

(b) warrants that, to the best of its knowledge, information and belief, no other person has asserted to the Proposer that such person has any IPRs or moral rights or rights of confidence in such proposal.

2.1.12 Subject to paragraphs 2.2.3(b)(iii), 2.5.9(c), 2.9.4A, 2.7A.9, 2.1.10A, 5.3.1(b) and 8.3, a Proposer may:

(a) withdraw their Modification Proposal on notice to the Modification Secretary at any time prior to the final evaluation by the Workgroup (in accordance with its terms of reference and working practices) of that Modification Proposal and, subject to paragraph 2.1.12B, any Modification Proposal so withdrawn shall lapse; or

(b) vary their Modification Proposal on notice (which may be given verbally) to the chair of the Workgroup at any time prior to the final evaluation by the Workgroup (in accordance with its terms of reference and working practices) of that Modification Proposal provided that such varied Modification Proposal:

(i) shall address the same issue or defect originally identified by the Proposer in their Modification Proposal; and

(ii) shall be deemed to be the Proposer’s Modification Proposal.

2.1.12A Subject to paragraph 2.1.10A, 5.3.1(b), 5.3.1A(a) and 8.3, the Panel may (but shall not be obliged to) require a Modification Proposal to be withdrawn at any time if, in the Panel’s opinion, the Proposer of that Modification Proposal is deliberately and persistently disrupting or frustrating the work of the Workgroup and that Modification Proposal shall be deemed to have been so withdrawn. In the event that a Modification Proposal is so withdrawn, the provisions of paragraphs 2.1.12B and 2.1.12C shall apply in respect of that Modification Proposal.

2.1.12B In relation to each Modification Proposal that has been withdrawn pursuant to paragraph 2.1.12(a) or 2.1.12A (other than Urgent Modification Proposals and Modification Proposals withdrawn following a Backstop Direction in accordance with paragraph 5.3B.1 in respect of which this paragraph shall not apply):

(a) the Modification Secretary shall promptly notify the persons referred to in paragraph 2.1.10(a);

(b) subject to paragraph 2.1.12B(d), such withdrawn Modification Proposal shall remain open to be adopted, in accordance with paragraph 2.1.12B(c) for a period commencing at 1200 hours on the first Business Day after the date of the Modification Secretary’s notice and ending at 1200 hours on the fifth Business Day thereafter;

(c) any of the persons referred to in paragraph 2.1.1 may (subject to paragraph 2.1.12B(e) and, if applicable, the circumstances set out in paragraph 2.1.1(d)) adopt the withdrawn Modification Proposal by notifying the Modification Secretary during the period set out in paragraph 2.1.12B(b) in which case:

(i) the adopted Modification Proposal shall continue through the Modification Procedures from the point at which it was withdrawn; and

(ii) the Proposer of the adopted Modification Proposal shall be entitled, pursuant to paragraph 2.4.5(a), to appoint a member of the Workgroup who shall replace any member appointed by the Proposer of the withdrawn Modification Proposal;

(d) the Modification Proposal shall be adopted by the person whose notice is first received by the Modification Secretary in accordance with paragraph 2.1.12B; and

(e) where a Modification Proposal has been withdrawn in accordance with paragraphs 2.1.12(a) or 2.1.12A, neither the Proposer of that Modification Proposal, nor any Affiliate of the Proposer that falls within the categories listed in paragraph 2.1.1, shall be entitled to adopt that Modification Proposal.

2.1.12C In relation to each Modification Proposal that has been withdrawn pursuant to paragraph 2.1.12(a), 2.1.12A, 5.3B.1, or withdrawn and subsequently adopted pursuant to paragraph 2.1.12B, the Modification Secretary shall promptly:

(a) revise the Modification Register; and

(b) notify the persons referred to in paragraph 2.1.10(a).

2.1.12D The changes effected by Modification Proposal P247 (in respect of paragraphs 1.3.5(a), 2.1.11, 2.1.12, 2.1.12A, 2.1.12B, 2.1.12C, 2.1.12D, 2.2.3(b)(iii), 2.2.11, 2.3.2(c), 2.4.5(a), 2.4.5C, 2.4.6, 2.4.9, 2.4.9A, 2.5.9(c), 2.9.4A, paragraph 1(a) of Annex F-1 and the definition of Proposer in Section X) shall only be effective in respect of any Modification Proposal raised, pursuant to paragraph 2.1.1, after the Relevant Implementation Date.

2.1.13 The provisions of Section B4 shall apply in relation to the convening and conduct of Panel meetings for the purposes of Modification Business.

2.1.14 Where there is a proposal made by the Panel to modify the Code pursuant to either paragraph 2.1.1(d) or Section G1.5, then the initial written assessment for that proposal may be presented at the same Panel meeting at which that proposal is made and the provisions of paragraph 2.2 shall apply.

2.1A Modification Proposals Submitted by Third Party Proposers

2.1A.1 An application by a person to be designated as a Third Party Proposer (such person being a "Third Party Applicant") shall be submitted in writing in accordance with BSCP40, and shall contain the following in relation to such request:

(a) a modification proposal that complies with paragraph 2.1.2;

(b) the rationale of the Third Party Applicant for requesting designation as an Third Party Proposer (including information on what other steps, if any, have been taken by the Third Party Applicant to have the Code issue or defect addressed);

(d) a letter agreement substantially in the form set out in BSCP40.

2.1A.2 If an application under 2.1A.1 fails in any material respect to comply with the requirements of that paragraph then the Modification Secretary may refuse to accept such application and the provisions of paragraph 2.1.3 shall apply mutatis mutandis in respect of such refused application.

2.1A.3 The Panel:

(a) subject to paragraphs 2.1A.3(b) and (c), shall consider a proposal made by a Third Party Applicant in accordance with this Section F;

(b) before designating a person as an Third Party Proposer, may conduct such consultation with Parties and interested third parties as it considers necessary; and

(c) may refuse to accept an application for designation as a Third Party Proposer in which case the Modification Secretary shall furnish the Third Party Applicant with the Panel’s reasons for such refusal.

2.1A.4 Subject to paragraphs 2.1A.5 and 2.1A.6, an application by a Third Party Applicant to be designated as a Third Party Proposer made pursuant to paragraph 2.1A.1 and not refused pursuant to paragraph to 2.1A.2 or 2.1A.3 shall be processed as a Modification Proposal as further provided in this paragraph 2 and:

(a) for the purposes of this Section F, the Third Party Proposer shall be the Proposer; and

(b) the Modification Secretary shall promptly notify the persons referred to in paragraph 2.1.10(a) that such application has been accepted by the Panel.

2.1A.5 Where a Third Party Applicant disagrees with a decision of the Panel not to designate them as a Third Party Proposer then such person may appeal the decision of the Panel to the Authority and the Panel shall give effect to any direction of the Authority arising from such appeal.

2.1A.6 Where a Party disagrees with the decision of the Panel to designate a person as a Third Party Proposer then such Party may appeal the decision of the Panel to the Authority.

2.1A.7 In respect of an appeal made under paragraph 2.1A.6:

(a) such appeal must be commenced by submitting to the Authority an outline of the objections to the designation by no later than fifteen Business Days after the date of the notice pursuant to paragraph 2.1A.4(b);

(b) the Party making such appeal shall promptly notify the Modification Secretary and the Modification Secretary shall, as soon as reasonably practical after it becomes aware of an appeal, notify each of the persons referred to in paragraph 2.1.1;

(c) the proposal shall continue to be processed as a Modification Proposal in accordance with this paragraph 2 pending the outcome of the appeal; and

(d) if such appeal is successful then the Modification Proposal shall be nullified provided that:

(i) if any subsequent modification proposal is accepted by the Panel that has, in the opinion of the Panel, substantially the same effect as a nullified Modification Proposal then the Panel shall have due regard to any assessment, analysis and consultations already undertaken in respect of the nullified Modification Proposal when determining which procedure or phase the proposal should be submitted to and the timetable to be followed in progressing such proposal; and

(ii) for the avoidance of doubt, a nullified Modification proposal shall not be a withdrawn Modification Proposal or a Rejected Modification Proposal.

2.1A.8 The Panel shall keep under review the volume of Modification Proposals being proposed by Third Party Proposers, the costs incurred by BSCCo in the administration of such Modification Procedures and the costs incurred by BSCCo in supporting Workgroups involved in the consideration of issues pursuant to paragraph 2.4.23 which have been raised by interested third parties pursuant to BSCP40 and:

(a) shall publish its findings on the BSC Website where it determines that there has been a material increase in volume and cost;

(b) may decide to propose a modification to the Code in order to address the findings of a review published by it pursuant to this paragraph.

2.2 Panel Proceedings

2.2.1 The provisions of this paragraph 2.2 are subject to paragraph 2.9.

2.2.2 The Proposer's representative shall attend the Panel meeting at which their Modification Proposal is first to be considered and the Panel may invite the Proposer's representative to present their Modification Proposal to the Panel.

2.2.3 In relation to each new Modification Proposal, the Panel shall determine:

(a) whether to amalgamate the Modification Proposal with any other Modification Proposal in accordance with paragraph 2.3;

(b) whether to:

(i) submit the Modification Proposal to the Definition Procedure pursuant to paragraph 2.5; or

(ii) submit the Modification Proposal to the Assessment Procedure pursuant to paragraph 2.6; or

(iii) proceed directly to the Report Phase pursuant to paragraph 2.7 (in which case the Proposer’s right to withdraw or vary their Modification Proposal shall lapse);

(c) where the Modification Proposal is to be submitted to the Definition Procedure or the Assessment Procedure pursuant to paragraph (b):

(i) the composition or identity and terms of reference of the Workgroup in accordance with the provisions of paragraph 2.4;

(ii) subject to paragraphs 2.2.8 and 2.2.9, the priority to be accorded to the Modification Proposal (as compared with other Pending Modification Proposals) and the timetable to apply for completion of the relevant procedure; and

(d) where the Modification Proposal is to proceed directly to the Report Phase pursuant to paragraph (b):

(i) whether the draft Modification Report shall contain a recommendation of the Panel to make the Proposed Modification;

(ii) the proposed Implementation Date for implementation, subject to the consent of the Authority, of the Proposed Modification (whether or not the Panel recommends the making of such Proposed Modification); and

(iii) whether (and the extent to which) the Modification Proposal will amend or supplement the EBGL Article 18 terms and conditions in which case:

(A) such Modification Proposal shall also constitute a proposal to amend or supplement the EBGL Article 18 terms and conditions for the purposes of Article 6(3) of the Guideline on Electricity Balancing; and

(B) even though such Modification Proposal may not have been raised by the NETSO, the NETSO hereby agrees that it shall constitute a proposal to amend the EBGL Article 18 terms and conditions but such agreement shall not fetter or restrict the NETSO’s rights under the Modification Procedures to express its views on that Modification Proposal.

2.2.4 For the avoidance of doubt, it is expected that the Panel would usually proceed directly to the Report Phase pursuant to paragraph 2.2.3(b)(iii) where the Modification Proposal is of a minor or inconsequential nature and/or where the recommendation which the Panel should make to the Authority in relation to such Modification Proposal would generally be considered to be self-evident.

2.2.5 If the Panel considers that there is insufficient information available to it to enable it to take a decision referred to in paragraph 2.2.3 in respect of a particular Modification Proposal, the Panel may in exceptional circumstances and having regard always to the requirements of paragraph 1.2.2 defer consideration of the relevant issue until the next succeeding Panel meeting provided that, in so doing, the Panel shall prescribe the steps which need to be taken (by the Modification Secretary, BSCCo or otherwise) to enable the Panel to decide the matter at such subsequent meeting (including completion, where necessary, of an initial assessment by BSCCo pursuant to paragraph 2.1.8).

2.2.6 If the Panel determines that a Modification Proposal is to be submitted to the Definition Procedure or the Assessment Procedure pursuant to paragraph 2.2.3, the Modification Secretary shall send a notice to that effect to each of the persons listed in paragraph 2.1.10(a) and shall invite them to provide comments to the Workgroup in respect of such Modification Proposal.

2.2.7 At each Panel meeting, the Panel shall consider in turn and vote (if appropriate) on any Modification Business which is outstanding at that time (including any new Modification Proposals, the report of any Workgroup and any draft Modification Reports).

2.2.8 In setting the timetable referred to in paragraph 2.2.3(c)(ii), the Panel shall exercise its discretion such that, in respect of each Modification Proposal, a Modification Report may be submitted to the Authority as soon after the Modification Proposal is made as is consistent with the proper definition and/or assessment and evaluation of such Modification Proposal, taking due account of its complexity, importance and urgency.

2.2.9 Without prejudice to paragraph 2.2.8, the Panel shall set the timetable referred to in paragraph 2.2.3(c)(ii) such that:

(a) in respect of a Definition Procedure, it is no longer than two months; and

(b) in respect of an Assessment Procedure, it is no longer than three months

unless the particular circumstances of the Modification Proposal (taking due account of its complexity, importance and urgency) justify an extension of such timetable (and provided that the Authority has not issued a contrary direction in accordance with paragraph 1.4.3 in respect thereof).

2.2.10 Having regard to the complexity, importance and urgency of particular Modification Proposals, the Panel may determine the priority of Modification Proposals and may (subject to paragraph 1.4.3) adjust the relevant modification timetable for each Modification Proposal accordingly.

2.2.11 The Panel may decide at any time to stop a Definition Procedure and/or an Assessment Procedure and proceed, in either case, directly to the Report Phase, in which case the Proposer’s right to withdraw or vary their Modification Proposal shall lapse.

2.3 Amalgamation

2.3.1 Subject to paragraph 1.4.3, the Panel may decide at any time to amalgamate a Modification Proposal with one or more other Modification Proposals where the subject-matter of such Modification Proposals is sufficiently proximate to justify amalgamation on the grounds of efficiency and/or where such Modification Proposals are logically dependent on each other.

2.3.2 Where Modification Proposals are amalgamated pursuant to paragraph 2.3.1:

(a) such Modification Proposals shall be treated as a single Modification Proposal;

(b) references in this Section F to a Modification Proposal shall include and apply to a group of two or more Modification Proposals so amalgamated;

(c) without prejudice to each Proposer’s right to withdraw their Modification Proposal prior to the amalgamation of their Modification Proposal, the Proposers of each such Modification Proposal shall co-operate in deciding which of them is to be the Proposer of the amalgamated Modification Proposal and, in default of agreement, the Panel shall nominate one of the Proposers for that purpose; and

(d) the Panel shall establish such arrangements as it considers appropriate for the evaluation of the amalgamated Modification Proposals.

2.4 Establishment of Workgroups

2.4.1 A Workgroup may be a group established in order to carry out a Definition Procedure pursuant to paragraph 2.5 or a group established in order to carry out an Assessment Procedure pursuant to paragraph 2.6.

2.4.2 Where the Panel decides to submit a Modification Proposal to the Definition Procedure or the Assessment Procedure, the Panel shall establish a Workgroup (or designate an existing Workgroup) to carry out such Procedure in accordance with the provisions of this paragraph 2.4.

2.4.3 A single Workgroup may be responsible for the definition and/or assessment of more than one Modification Proposal at the same time and the Panel may establish one or more Workgroups on a standing basis to carry out definition and assessment of Modification Proposals (which may from time to time be submitted) whose subject-matter falls into a particular area or areas.

2.4.4 A Workgroup shall comprise at least five members selected by the Panel for their relevant experience and/or expertise in the areas forming the subject-matter of the Modification Proposal(s) to be considered by such Workgroup, and in the case of a standing Workgroup, forming the subject matter of the issues determined by the Panel under the terms of reference for that standing Workgroup (and the Panel shall ensure, as far as possible, that an appropriate cross-section of experience, interests and expertise is represented on such Workgroup).

2.4.5 In addition to the members appointed by the Panel pursuant to paragraph 2.4.4:

(a) the Proposer shall be entitled to appoint its representative as a member of the Workgroup which is to consider the Proposer's Modification Proposal (and who, in the case of a standing Workgroup, shall be a member for the purposes of that Modification Proposal only);

(b) the NETSO shall be entitled to appoint one member of any Workgroup (unless the NETSO is the Proposer, in which case paragraph (a) applies); and

(c) unless the Panel otherwise determines, the Panel shall appoint at least one additional member of each Workgroup who shall be an employee of BSCCo, and BSCCo shall make appropriately qualified BSCCo staff available for this purpose.

2.4.5A If, and only if, the Panel is of the view that a particular Modification Proposal may impact upon the STC, the Panel may invite the STC Committee to appoint a representative to become a member of any Workgroup formed to carry out a Definition Procedure or Assessment Procedure in relation to such a Modification Proposal.

2.4.5B In the event that the STC Committee appoints a representative to become a member of a Workgroup:

(a) the membership of such representative shall not become effective until the representative has complied with paragraph 2.4.6; and

(b) such representative as a member of the Workgroup shall act in accordance with paragraphs 2.4.9 and 2.4.14 and shall be subject to all the other provisions of the Code applicable to a member of a Workgroup.

2.4.5C A Proposer may, pursuant to paragraph 2.4.5(a), appoint a representative of BSCCo as a member of the Workgroup (provided that BSCCo shall act as an impartial representative of the Proposer’s views and shall not act as an advocate of the Modification Proposal and, where the Workgroup’s terms of reference provide for voting, BSCCo shall not have voting rights when appointed in such capacity). If the Proposer appoints a representative of BSCCo as a member of Workgroup, the Proposer shall not have the right to vary their Modification Proposal pursuant to paragraph 2.1.12(b).

2.4.6 Prior to establishing the composition of a Workgroup:

(a) each proposed member of the Workgroup shall be required to confirm to the Panel that they will be available as required throughout the relevant Definition Procedure or Assessment Procedure (or, in the case of a standing Workgroup, during such period as the Panel may specify) to attend Workgroup meetings and to carry out work to be undertaken outside those meetings as necessary; and

(b) with the exception of a member appointed pursuant to paragraph 2.4.5(a), where the proposed member is employed, they shall provide to the Modification Secretary a letter from their employer agreeing that they may act as a member of a Workgroup, and that the requirements of paragraph 2.4.9 shall prevail over their duties as an employee.

2.4.7 The Panel shall appoint one of the members of a Workgroup to act as chair of the Workgroup, and the Panel may change the chair of a Workgroup from time to time as it sees fit.

2.4.8 A Workgroup shall not be a Panel Committee for the purposes of Section B5.

2.4.9 A member of a Workgroup shall act impartially and, subject to paragraph 2.4.9A, shall not be representative of a particular person or class of persons (and, accordingly, no member shall agree to follow or be bound by the instructions of any person or body, other than the Panel pursuant to this Section F, in the exercise of their functions as a member of a Workgroup).

2.4.9A The restrictions in paragraph 2.4.9 on a member of a Workgroup not being representative of a particular person or class of persons shall not apply to a member appointed pursuant to paragraph 2.4.5(a) insofar as that member shall be entitled to represent the views of the Proposer.

2.4.10 The Panel may add further members to a Workgroup at any time.

2.4.11 The Panel may (but shall not be obliged to) replace any member of a Workgroup appointed pursuant to paragraph 2.4.4 at any time if, in the Panel’s opinion, such member is unwilling or unable for whatever reason to fulfil that function and/or is deliberately and persistently disrupting or frustrating the work of the Workgroup.

2.4.12 The Panel shall determine the terms of reference of each Workgroup (which in the case of a standing Workgroup may include standing terms of reference as well as specific terms of reference for any particular Modification Proposal) and may change those terms of reference from time to time as it sees fit.

2.4.13 The terms of reference of a Workgroup shall include provision in respect of (among other things) the following matters:

(a) those areas of a Workgroup's powers or activities which require the prior approval of the Panel;

(b) the seeking of instructions, clarification or guidance from the Panel;

(c) in the case of a standing Workgroup, the area(s) of subject-matter of Modification Proposals for which the Group may be designated under paragraph 2.4.3; and

(d) in the case of a standing Workgroup, authorise the Group from time to time to consider (outwith the context of any particular submitted Modification Proposal) issues generally related to the relevant area(s) of subject-matter, designated to the Group by the Panel under 2.4.13(c).

2.4.14 Each Workgroup (and each member of a Workgroup) shall:

(a) act in accordance with its terms of reference as determined (and, if applicable, changed) pursuant to paragraph 2.4.12;

(b) have due regard to the objectives referred to in paragraph 1.2.2 (as if references to the Panel were references to the Workgroup); and

(c) if a Workgroup is unable to reach agreement on any matter, the report of the Workgroup shall instead include a summary of the views of the members of the Workgroup.

2.4.15 In addition to any staff made available to act as members of a Workgroup pursuant to paragraph 2.4.5, BSCCo shall provide such staff, facilities and support to each Workgroup (including the engagement of external consultants and advisers) as such Workgroup may reasonably require to assist with the administration and operation of the business of such Workgroup provided that any material expenditure (as determined by the Panel in respect of a particular Workgroup) shall require the prior approval of the Panel (in consultation with BSCCo).

2.4.16 The Modification Secretary (or their deputy) shall act as secretary to each Workgroup meeting.

2.4.17 The Modification Secretary shall notify the Authority in advance of all Workgroup meetings and a representative of the Authority may attend and speak at any such meeting (provided that any observations such representative may make shall not be taken to bind the Authority in any way in relation to the Modification Proposal being discussed).

2.4.18 Subject to paragraph 2.4.19, any meeting of a Workgroup shall be open to attendance by a representative of any Party and any other person entitled to receive notice of Modification Proposals under paragraph 2.1.10; and any person so attending such a meeting may speak if invited to do so by the chair of the meeting, but (if the Group’s terms of reference provide for voting) shall not vote at the meeting.

2.4.19 Paragraph 2.4.18 shall not apply:

(a) in the case of a meeting held by telephone conference; or

(b) where it is impractical in the opinion of the chair of the meeting to hold the meeting in open session;

2.4.20 Subject to the provisions of this paragraph 2.4 and unless otherwise determined by the Panel, a Workgroup shall develop and adopt its own internal working procedures for the conduct of its business and shall provide a copy of such procedures to the Modification Secretary in respect of each Modification Proposal for which it is responsible.

2.4.21 The Modification Secretary shall ensure that details of the composition, terms of reference, timetable of meetings and internal working procedures of each Workgroup are published on the BSC Website.

2.4.22 Without prejudice to paragraph 2.7.8, each report prepared by a Workgroup under this Section F shall be addressed and furnished to the Panel and none of the facts, opinions or statements contained in such report may be relied upon by any other person.

2.4.23 With a view to facilitating consideration of whether to propose modifications of the Code and how to frame such proposals, BSCCo may convene, in accordance with BSCP40, a group to consider generally issues relating to the Code, its application or implementation, or any manner in which the Code might be modified provided that, save as specified in BSCP40, neither the views of the group nor anything done by it in relation to such an issue shall have any consequence or significance in relation to the Code or its implementation or operation.

2.5 Definition Procedure

2.5.1 The provisions of this paragraph 2.5 shall apply if the Panel decides to submit a Modification Proposal to the Definition Procedure pursuant to paragraph 2.2.

2.5.2 The purpose of the Definition Procedure is to define the issues raised by a Modification Proposal in sufficient detail to enable the Panel to determine which of the options set out in paragraph 2.5.9 is the most appropriate in all the circumstances.

(a) an assessment of the issues raised by the Modification Proposal with supporting information and data to explain the effect of such issues by reference to the Applicable BSC Objective(s) and a summary of such assessment;

(b) an analysis of and the views and rationale of the Workgroup as to whether (and, if so, to what extent) the issues raised by the Modification Proposal warrant further assessment and evaluation in accordance with paragraph 2.6;

(c) a detailed summary of the representations made by Parties and interested third parties during the consultation undertaken by the Workgroup (pursuant to paragraph 2.2.6 and, where applicable, paragraph 2.5.5(b)) and the comments and views of the Workgroup in respect thereof;

(d) a summary of any analysis prepared by the NETSO and the comments and views of the Workgroup in respect thereof;

(e) a summary of any analysis prepared by relevant BSC Agents and the comments and views of the Workgroup in respect thereof;

2.5.9 Following completion of the Workgroup's report pursuant to paragraph 2.5.7, the Panel shall consider the Workgroup's report at the next following Panel meeting and shall determine whether to:

(a) refer the Modification Proposal back to the Workgroup for further analysis (in which case, the Panel shall determine the timetable and terms of reference to apply in relation to such further analysis);

(b) submit the Modification Proposal to the Assessment Procedure pursuant to paragraph 2.6; or

(c) proceed directly to the Report Phase pursuant to paragraph 2.7 (in which case the Proposer’s right to withdraw or vary their Modification Proposal shall lapse),

and, in the case of paragraphs (a) or (b), the Panel may instruct the Panel Secretary to initiate a further process of consultation (in accordance with the terms of reference determined by the Panel).

2.6 Assessment Procedure

2.6.1 The provisions of this paragraph 2.6 shall apply if the Panel decides to submit a Modification Proposal to the Assessment Procedure pursuant to paragraph 2.2, 2.5.9(b) or 7.3.4(c).

2.6.2 The purpose of the Assessment Procedure is to evaluate whether the Proposed Modification identified in a Modification Proposal better facilitates achievement of the Applicable BSC Objective(s) and whether any alternative modification would, as compared with the Proposed Modification, better facilitate achievement of the Applicable BSC Objective(s) in relation to the issue or defect identified in the Modification Proposal.

2.6.2A Where a Proposed Modification and any Alternative Modification are likely to have a material impact on greenhouse gas emissions then the evaluation pursuant to paragraph 2.6.2, in respect of the Applicable BSC Objective(s), shall include an assessment of the quantifiable impact of the Proposed Modification and any Alternative Modification on greenhouse gas emissions and such assessment shall be conducted in accordance with the guidance (on the treatment of carbon costs and evaluation of greenhouse gas emissions) that may be issued by the Authority from time to time.

2.6.3 The Panel shall establish or designate a Workgroup and shall determine its terms of reference in accordance with the provisions of paragraph 2.4.

2.6.4 The Workgroup shall:

(a) evaluate the Modification Proposal for the purpose set out in paragraph 2.6.2;

(b) where appropriate, develop an alternative proposed modification (the "Alternative Modification") which, as compared with the Proposed Modification, would better facilitate achievement of the Applicable BSC Objective(s);

(i) whether, and the extent to which, the Modification Proposal will amend the EBGL Article 18 terms and conditions; and

(ii) where the Workgroup considers that a Modification Proposal may amend the EBGL Article 18 terms and conditions, the impact of those amendments on the EBGL Objectives; and

(d) prepare a report for the Panel (in accordance with the timetable determined by the Panel pursuant to paragraph 2.2 or 2.5.9(b)) which shall set out, in relation to the Proposed Modification and any Alternative Modification, the matters referred to in Annex F-1, to the extent applicable to the proposal in question.

2.11.8 The Panel shall apply to the Authority for an extension to the Implementation Date if it becomes aware of any circumstance which is likely to cause a delay in the implementation of an Approved Modification.

2.11.9 The Panel may, after consultation with the persons listed in paragraph 2.1.10(a), apply to the Authority (providing copies of the representations made in such consultation) to bring forward the Implementation Date if the Panel is reasonably satisfied that an Approved Modification is capable of being implemented sooner than the current Implementation Date and is of the opinion that its implementation should be so brought forward.

2.11.10 Where a Relevant Challenge is made and the Panel considers the Implementation Date or a "Proposed Implementation Date" (as defined in paragraph 2.11.15) relating to a Modification Proposal is or may no longer be appropriate or may expire prior to a determination made in relation to the Relevant Challenge, the Panel shall consult with the persons listed in paragraph 2.1.10(a) as to the following:

(a) whether a Conditional Implementation Date in replacement of the current Implementation Date or Proposed Implementation Date is appropriate or advisable as a result of the Relevant Challenge; and

(b) (if the Panel considers it appropriate) whether the Conditional Implementation Date should replace the current Implementation Date or Proposed Implementation Date subject to the condition precedent that it shall be effective only if the determination of the relevant appeal or judicial review is received on or before (or not received after) a specified date.

2.11.11 After undertaking a consultation pursuant to paragraph 2.11.10 the Panel may recommend to the Authority a Conditional Implementation Date which is subject to the condition precedent that it shall be effective only if the determination in the relevant appeal or judicial review is received on or before (or not received after) a specified date.

(b) Proposed Implementation Date set out in any Modification Report relating to the relevant Modification Proposal.

2.11.14 Where the Panel considers that:

(b) a Relevant Challenge;

the Party must submit written notice of such application and/or Relevant Challenge to the Modification Secretary no later than five Business Days from the date such application and/or Relevant Challenge is made.

2.11.19 Following the completion of a consultation held pursuant to paragraph 2.11.18, the Panel shall recommend a revised proposed Implementation Date to the Authority.

2.11.20 If the Authority decides to accept the Panel’s recommendation pursuant to paragraph 2.11.19 the Authority shall notify the Panel of its decision and the revised proposed Implementation Date so accepted shall, for the purposes of the Code, be deemed to have replaced the proposed Implementation Date specified in the relevant Modification Report.

2.11.21 In respect of any consultation held pursuant to paragraph 2.11.18, the Panel may in addition consult on any matters relating to the relevant Modification Report which in the Panel’s opinion have materially changed since the relevant Modification Report was submitted to the Authority in accordance with paragraph 2.7.6 and where it does so, the Panel shall report on such matters as part of its recommendation in accordance with paragraph 2.11.19.

2.11.22 In respect of an Approved Self-Governance Modification Proposal that was comprised in a cross code change package, the provisions of this paragraph 2.11 relating to the Authority’s power to revise proposed Implementation Dates shall apply to the Panel mutatis mutandis.

SECTION G: CONTINGENCIES

1. GENERAL

1.1 Provisions in Code

1.1.1 This Section G sets out or refers to provisions of the Code which are to apply in certain contingencies, and related provisions.

1.1.2 The following provisions of the Code address the possibility of certain emergencies and other unusual or unexpected events of various kinds:

(a) Section P5, which addresses circumstances in which the ECVAA may be unable to receive Energy Contract Volume Notifications and Metered Volume Reallocation Notifications;

(b) Section Q7, which addresses the possibility of manifest errors in the submission or acceptance of Bids and Offers;

(d) paragraph 3, which addresses System Restoration Periods; and

(e) paragraph 4, which applies where the Secretary of State exercises certain emergency powers.

1.1.3 For the avoidance of doubt, paragraph 1.1.2 is not intended to be an exclusive list of provisions of the Code which address failures or delays or other abnormalities in the implementation of the Code.

1.1.4 The provisions of the Code referred to in paragraph 1.1.2 are "Contingency Provisions".

1.1.5 Paragraph 5 sets out arrangements for giving effect to the recovery of Exceptional Costs pursuant to the Fuel Security Code.

1.1.6 Paragraph 6 sets out arrangements for validating that Trading Charges relating to Network Gas Supply Emergency Acceptances are consistent with the Network Gas Supply Emergency Adjustment Principles, and where appropriate amending data relating to those Network Gas Supply Emergency Acceptances better to reflect those principles.

1.2 Exclusion of reconciliation

1.2.1 Where, pursuant to any Contingency Provision, any entitlement or liability by way of Ad-hoc Trading Charge is to be determined in relation to any Settlement Day:

(a) the amount of such Ad-hoc Trading Charge shall be determined on the basis of data derived from the Initial Settlement Run (or if any Reconciliation Settlement Run has already been carried out at the time at which the amount of such charge is to be determined, the latest such Reconciliation Settlement Run);

(b) unless the Panel expressly otherwise decides, no adjustment or reconciliation shall be made in the determination of such Ad-hoc Trading Charge upon or as a result of the later carrying out of any Reconciliation Settlement Run or other adjustment of any such data;

(c) the Ad-hoc Trading Charge itself will have arisen outside any Settlement Run and accordingly shall be excluded from account (in both paragraphs (a) and (b) of Section N6.4) by the FAA in carrying out any reconciliation under that Section.

1.3 Party Daily Reallocation Proportions

1.3.1 For the purposes of the Code, in relation to any Trading Party and any Settlement Day, the "Party Daily Reallocation Proportion" is the proportion determined as:

RCRC_p / Σ_p RCRC_p

where Σ_p represents the sum over all Trading Parties.

1.3.2 It is acknowledged that in certain circumstances the value of Party Daily Reallocation Proportion for a Trading Party might be negative, in which case any reference (in any Contingency Provision) to a liability of that Trading Party as to its Party Daily Reallocation Proportion of any amount shall be construed as an entitlement.

1.3.3 In accordance with paragraph 1.2.1, in the application of any Contingency Provision the Party Daily Reallocation Proportions shall be determined by reference to values of Daily Party Residual Settlement Cashflow determined in the Settlement Run (excluding the Interim Information Settlement Run) last carried out for the relevant Settlement Day before such proportions are to be determined, and shall not (unless the Panel decides otherwise) subsequently be revised.

1.4 Application of Contingency Provisions

1.4.1 For the avoidance of doubt, the Contingency Provisions shall apply (in accordance with their terms) only in relation to Settlement Periods commencing on or after the Go-live Date, but an event or circumstance giving rise to the application or operation of such provisions may occur or prevail before or on or after the Go-live Date.

1.5 Review of emergency arrangements

1.5.1 If at any time the Secretary of State announces an intention to carry out a review of arrangements which apply or may apply in anticipation of or following the exercise of any of the Secretary of State’s powers under Sections 34 and 35 of the Act, Section 96 of the Act, and sections 1 to 4 of the Energy Act 1976 (including the arrangements provided for in the Fuel Security Code) the provisions of this paragraph 1.5 shall apply.

1.5.2 BSCCo shall participate (as and to the extent requested by or on behalf of the Secretary of State) in any review of the type referred to in paragraph 1.5.1.

1.5.3 Following any review of the type referred to in paragraph 1.5.1 (or during such review if so requested by the Secretary of State), the Panel shall propose a modification of the Code (including the provisions in paragraph 4) which in the opinion of the Panel, on the recommendation of BSCCo, and after consultation with the Secretary of State and the Authority, is appropriate to support and/or to reflect any modifications of the arrangements referred to in that paragraph (including any modifications of the Fuel Security Code), or any new such arrangements, which may be made or established (by or on behalf of or at the behest of the Secretary of State) in consequence of such review.

1.5.4 Where the Panel has proposed a modification of the Code under paragraph 1.5.3, the Panel shall take steps, in consultation with the Authority, to coordinate the application (in relation to such proposal) of the procedures in Section F with other steps taken in consequence of such review for the consideration of modifications to (or establishment of) arrangements referred to in paragraph 1.5.3.

2. AVOIDABLE COSTS

2.1 General

2.1.1 This paragraph 2 applies for the purposes of determining Avoidable Costs (which are used in the calculation of compensation claims for certain Contingency Provisions) in relation to a BM Unit and:

(a) such changes ("relevant changes") in Exports and/or Imports of that BM Unit during a Settlement Period as are specified in or determined pursuant to the relevant Contingency Provision; or

(b) where paragraph 3 (System Restoration) applies, a BM Unit that is the subject of a system restoration instruction (as defined in paragraph 3.3.1C) whether or not relevant changes occur.

2.1.2 Where any such Contingency Provision applies, the Panel shall determine, in its opinion, what is the amount of the net costs of operating the BM Unit which would not have been incurred but for:

(a) the relevant changes in Exports and/or Imports: or

(b) a system restoration instruction.

2.1.3 For the purposes of the Code, the "Avoidable Costs" shall be the amount determined by the Panel under paragraph 2.1.2 (which may for the avoidance of doubt be a negative amount, in a case where net costs were saved or revenues earned).

2.1.4 In determining what are the costs of operating a BM Unit and what such costs would not have been incurred (as provided in paragraph 2.1.2), the Panel shall have regard to the following:

(a) costs include lost revenues, and costs saved include revenues earned;

(b) in the case of a BM Unit comprising premises of a Customer, the costs which are to be counted are the costs incurred by the Customer;

(i) costs directly incurred in the operation of the Plant and Apparatus comprised in the BM Unit;

(ii) costs which were reasonably and prudently incurred, and incurred pursuant to commitments reasonably and prudently made; and

(iii) costs the amount of which would be expected to differ according to whether there occurred the relevant changes in Exports and/or Imports or changes in operation to comply with a system restoration instruction in the relevant Settlement Period alone;

(d) costs include costs (incurred or saved) of consumption of electricity or fuel;

(e) the following costs are not to be counted:

(i) costs or losses in respect of damage to property (including Plant or Apparatus) or death or injury to persons;

(ii) insurance premia; and

(iii) financing costs and overhead costs;

(f) amounts payable (other than by way of rebate of payment for supply), under any contract or otherwise, by way of compensation for loss of supply or otherwise in consequence of relevant changes in Exports and/or Imports, by the Lead Party to the person referred to in paragraph (b), are to be disregarded; and

(g) amounts payable or receivable under the Code in respect of Trading Charges or BSCCo Charges are to be disregarded. 2.2 Procedures2.2.1 Where under any Contingency Provision the amount of Avoidable Costs is to be determined for any Settlement Period or Periods:

(a) the Lead Party shall prepare, consistently with the principles in paragraphs 2.1.3 and 2.1.4, and submit to BSCCo its estimate (for each such Settlement Period) of the net costs of operating the BM Unit which would not have been incurred:

(i) that the Network Gas Supply Imbalance Adjustment Volume (QNGSIAij) for each BM Unit ‘i' and Settlement Period ‘j’ is equal to the total volume of Active Energy that:

(1) prior to the Bid-Offer Acceptance Time of the Network Gas Supply Emergency Acceptance the relevant Lead Party or Subsidiary Party intended (or can reasonably be inferred to have intended) should be generated using Generating Unit(s) contained within BM Unit ‘i’;

(2) could not be generated by those Generating Unit(s) as a result of the Network Gas Supply Emergency Acceptance; and

(3) was subject to agreement(s) that are consistent with the requirements of paragraph 6.1.4, and for which:

(a) prior to the Bid-Offer Acceptance Time of the Network Gas Supply Acceptance the relevant Lead Party or Subsidiary Party agreed with the counterparty the volume of energy to be transferred in relation to Settlement Period ‘j’,; and/or

(ii) that the Network Gas Supply Total Bid Payment (TNGSB_i) payable by the Lead Party equals the net saving in Avoidable Costs as a result of the Acceptance;

(b) determine whether the Trading Charges relating to each Network Gas Supply Emergency Acceptance could be made more consistent with the Network Gas Supply Emergency Adjustment Principles by amending data as follows for purposes of Settlement:

(h) other provisions defining the legal and contractual relationship between the Parties.

1.2 Internal structure

1.2.1 The Code comprises:

(a) each of the Sections; and

(b) any Annex attached to a Section; and

1.2.3 The Code also refers to and creates obligations in respect of Code Subsidiary Documents.

(e) Data Catalogues;

(f) Communication Requirements Documents

(g) the Reporting Catalogue; and

(h) the LFM Specification.

1.2.5 Subject to Section L3.2, a reference in the Code or in any Code Subsidiary Document to a Code Subsidiary Document shall be to the version of that Code Subsidiary Document then in force, unless the context otherwise requires.

1.2.6 Code Subsidiary Documents shall have binding effect for the purposes of the Code.

1.2.7 Subject to paragraph 1.2.8:

(a) each Party and each BSC Agent shall comply with (and each Party shall ensure that its Party Agents comply with) each of the Code Subsidiary Documents in force from time to time (whether or not such Code Subsidiary Document is expressly identified or referred to in, or in a particular Section of, the Code) to the extent such Code Subsidiary Document is applicable to such Party, BSC Agent or Party Agent;

(b) without prejudice to paragraph 1.5 and other than in Section A, Section F, Section H and Section X (including Annex X-1 and Annex X-2) references in the Code to the Code shall be interpreted to include all relevant Code Subsidiary Documents, unless the context otherwise requires; and

1.2.8 The provisions of paragraph 1.2.7 shall not apply to the BSC Service Descriptions (but without prejudice to any obligations of BSC Agents under the BSC Agent Contracts).

1.3 Establishment of Code Subsidiary Documents

1.3.1 The Code Subsidiary Documents in force as at the Code Effective Date shall be those listed in the Implementation Scheme and they shall be deemed to be adopted by the Panel, for the purposes of the Code, as at the Code Effective Date (subject to the provisions of the Implementation Scheme).

1.3.2 BSCCo shall:

(a) maintain an up-to-date list of the Code Subsidiary Documents, indicating the version number of each Code Subsidiary Document then in force (and the version numbers of previous versions) together with the date with effect from which each such version applies or applied;

(b) make a copy of such list available to any person on request; and

(c) maintain a library of all past and current versions of each Code Subsidiary Document (including, in the case of Codes of Practice, the versions referred to in Section L3.2.3).

1.3.3 Existing Code Subsidiary Documents may be modified and new Code Subsidiary Documents may be created in accordance with Section F3.

1.4 Access to Code

1.4.1 BSCCo shall provide a copy of the Code and of any Code Subsidiary Document to any person on request, subject (other than in the case of the Authority) to payment by such person of an amount (as approved by the Panel from time to time) not exceeding the reasonable costs of BSCCo in making and providing such copy.

1.4.2 In complying with paragraph 1.4.1 (and without prejudice to the requirements of that paragraph), BSCCo shall, and shall be entitled to, take such steps as it considers appropriate to protect the IPRs which BSCCo holds in such documents pursuant to paragraph 4.7.

1.4.3 Notwithstanding paragraph 1.4.1, BSCCo may, with the prior approval of the Panel, refuse to provide a copy of any Code Subsidiary Document (or part of it) to a third party or to third parties generally (or may make the provision thereof subject to conditions) to the extent only and for the period that the provision of such Code Subsidiary Document (or part of it) to such third party or parties would, in the opinion of BSCCo, substantially prejudice the interests of all Parties collectively or classes of Parties collectively.

1.4.4 Where, with the approval of the Panel, BSCCo determines that a Code Subsidiary Document (or part of it) should not be made available to a third party or to third parties generally pursuant to paragraph 1.4.3, BSCCo shall notify Parties and the Authority accordingly.

1.4.5 Subject to any existing confidentiality obligation, each other Party shall be free to disclose the Code or any Code Subsidiary Document to any third party to the extent that BSCCo would be entitled to make such document(s) available to that third party pursuant to this paragraph 1.4 and subject to compliance with any steps BSCCo may prescribe under paragraph 1.4.2, provided always that, where BSCCo refuses to provide a copy of a Code Subsidiary Document to a third party or third parties pursuant to paragraph 1.4.3, such Party shall not disclose that Code Subsidiary Document to such third party or parties.

1.5 Precedence

1.5.1 In the event of any conflict between the provisions of the Code and:

(a) the provisions of any Code Subsidiary Document;

(b) the Code Administration Code of Practice Principles; and/or

(c) the provisions of any other document established or adopted under and pursuant to the Code or any Code Subsidiary Document,

the provisions of the Code shall prevail.

1.5.2 In the event of any conflict between the provisions of one type of Code Subsidiary Document and another, or between the provisions of one Code Subsidiary Document and another:

(a) the Codes of Practice shall take precedence over all other types of Code Subsidiary Document;

(b) subject to paragraph (a), the Panel shall determine which provision is to take precedence pending modification of the Code Subsidiary Document(s),

and the Panel shall take steps in accordance with Section F3 to remove such conflict.

1.5.3 In the event of any conflict between the provisions of a Code Subsidiary Document and the provisions of any other document established or adopted under and pursuant to the Code or any Code Subsidiary Document, the provisions of the Code Subsidiary Document shall prevail.

1.5.4 The provisions of this paragraph 1.5 shall be subject to any express provision to the contrary in the Code.

1.5.5 Not used.

1.6 Relationship with other documents

1.6.1 In the event of any conflict between the provisions of the Retail Energy Code and the provisions of the Code, no Party shall be liable hereunder or under the Retail Energy Code as a result of complying with its obligations under the Code or under the Retail Energy Code provided that each Party shall take such steps within its power as may be necessary, subject to and in accordance with the provisions of the Code and the Retail Energy Code relating to modifications, to resolve such conflict as soon as possible.

1.6.1A Notwithstanding paragraph 1.6.1, the Parties acknowledge that, depending on the nature of the conflict between the Retail Energy Code and the Code, it may not be practicable or desirable for individual Parties to comply with differing and conflicting obligations and, in that event, the Panel and the REC Code Manager, with the approval of the Authority, may determine which provisions are to prevail pending modification of the Retail Energy Code and/or the Code to remove such conflict.

1.6.2 In the event of any conflict between the provisions of the Grid Code and the provisions of the Code, no Party shall be liable hereunder or under the Grid Code as a result of complying with its obligations under the Code or under the Grid Code provided that each Party shall take such steps within its power as may be necessary, subject to and in accordance with the provisions of the Code and the Grid Code relating to modifications, to resolve such conflict as soon as possible.

1.6.3 Notwithstanding paragraph 1.6.2, the Parties acknowledge that, depending on the nature of the conflict between the Grid Code and the Code, it may not be practicable or desirable for individual Parties to comply with differing and conflicting obligations and, in that event, the Panel and the NETSO, with the approval of the Authority, may determine which provisions are to prevail pending modification of the Grid Code and/or the Code to remove such conflict.

1.6.4 For the avoidance of doubt, a conflict for the purposes of this paragraph 1.6 arises where compliance with the requirements of one document would necessarily (but for the provisions of this paragraph 1.6) result in a breach of the other document and, accordingly, the existence of an additional or supplementary requirement under one or other document in relation to matters forming the subject of both documents does not, of itself, constitute a conflict for the purposes of this paragraph 1.6.

1.6.5 In this paragraph 1.6, references to the Code include each of the Code Subsidiary Documents.

1.6.6 BSCCo shall inform the Panel and the NETSO as soon as reasonably practicable where it becomes aware of any conflict or material inconsistency between the Code and another applicable Industry Code.

1.7 IPR Litigation Requirements Document

1.7.1 With reference to the arrangements described or referred to in the IPR Litigation Requirements document referred to in Section A2.2.5, it is agreed that those arrangements shall take effect in accordance with their terms; and Parties shall be bound by the effect of those arrangements; and the Panel and BSCCo shall have and discharge their respective powers, functions and responsibilities set out in and in accordance with those arrangements; and all costs, expenses and liabilities incurred by BSCCo in connection with or pursuant to those arrangements shall (subject as provided therein) be BSC Costs.

2.2.4 The obligations in paragraph 2.2.1 shall not apply to any person who becomes a Party after the date notified by the Secretary of State to the Panel for the purposes of this paragraph 2.2.4 provided that such person shall be bound by the effect of the provisions of the Implementation Scheme and the Scheme Subsidiary Documents (and any steps taken or arrangements made thereunder) as they apply to or affect the Code or any Code Subsidiary Documents (and the rights and obligations of the Parties thereunder) to the extent such provisions, steps or arrangements have an effect beyond that date.

(i) upon termination or expiry of the Processing in connection with which the BSC Processor Processes the Relevant BSC Personal Data, destroy the Relevant BSC Personal Data that is within its possession or control (including where subcontracted to a third party), save that this requirement shall not apply to the extent that the Processor: (i) is required by a Legal Requirement to retain the Relevant BSC Personal Data in which instance the Processor shall become a BSC Controller of such data; and/or (ii) continues to process the Relevant BSC Personal Data for other lawful purposes (either as a Controller or as a Processor on behalf of other Controllers); and

(j) permit any person appointed or approved by the Panel to audit compliance with this paragraph 4.9 and make available, on request, all information reasonably necessary to demonstrate such compliance.

4.9.5 Each BSC Processor shall ensure that its sub-processors, in respect of the Relevant BSC Personal Data, are subject to written contractual obligations in respect of the Processing of that Relevant BSC Personal Data which are substantially the same as the Processor obligations under the Code.

4.9.6 Each BSC Controller hereby gives each BSC Processor general authorisation to engage sub-processors from time to time as deemed necessary by that BSC Processor to fulfil functions required by the Code. Each BSC Controller hereby confirms that it does not object to the engagement of any sub-processors engaged in accordance with this paragraph at any time. Where a sub-processor is appointed (including changes to appointed sub-processors) in accordance with this paragraph, the BSC Processor shall maintain a list of sub-processors (including details of the processing it performs or will perform) and provide such list of then current sub-processors, from time to time, to the Panel (on behalf of the BSC Controllers collectively) and publish that list on the BSC Website.

4.9.7 Notwithstanding such general consent to appointment of sub-processors under paragraph 4.9.6, the Panel (acting on behalf of the BSC Controllers collectively), may object to the appointment of a sub-processor on reasonable grounds relating to the protection of Relevant BSC Personal Data. In the case of such an objection, the BSC Processor will either not appoint the sub-processor or, if already appointed, terminate the sub-processor's services (either immediately if the sub-processor has caused a breach of any of the BSC Processor obligations under this paragraph 4.9 or otherwise within a reasonable timescale of the Panel’s objection, without resulting in a lack of continuity of BSCCo’s obligations under this Code).

4.9.8 Each BSC Processor shall not transfer or process the Relevant BSC Personal Data outside the United Kingdom and European Economic Area unless the BSC Processor has taken such measures as are necessary to ensure the transfer is in compliance with Data Protection Legislation, which may include transferring the Relevant BSC Personal Data to a recipient:

(a) in a country that the Secretary of State has decided provides adequate protection for Personal Data;

(b) that has achieved binding corporate rules authorisation in accordance with Data Protection Legislation; or

(c) with whom it has that has executed relevant standard contractual clauses adopted or approved by the Secretary of State or otherwise permitted by the Data Protection Legislation and in respect of which it has carried out an adequate transfer risk assessment and provided a copy of such assessment to the BSC Controller on request.

4.9A Data Protection – Further Provisions

4.9A.1 It is acknowledged and agreed that BSCCo may need to Process Relevant BSC Personal Data in order to perform its performance assurance obligations, role and functions under the Code. It is further acknowledged and agreed that for such purposes, BSCCo is acting as a BSC Controller in respect of any Relevant BSC Personal Data that it Processes and accordingly paragraph 4.8 applies.

4.9A.2 Other than as required under the Code, BSCCo may only Process Relevant BSC Personal Data (including sharing Relevant BSC Personal Data with a third party controller) where:

(a) that third party is required or permitted to Process Relevant BSC Personal Data pursuant to a Legal Requirement or the terms of a Nominated Agreement or Industry Code;

(b) the basis and terms on which that third party may Process the Relevant BSC Personal Data are specified in, or pursuant to, such Legal Requirement, Nominated Agreement or Industry Code;

(c) BSCCo has entered into data sharing agreements with that third party on terms that, amongst other things, complies with Data Protection Legislation and limits any uses of the Relevant BSC Personal Datato that which is necessary for the purposes of the Code or the purposes of the relevant Legal Requirement, Nominated Agreement or Industry Code.

SECTION M: CREDIT COVER AND CREDIT DEFAULT

1. GENERAL

1.1 Introduction

1.1.1 This Section sets out:

(a) the basis on which Energy Indebtedness of an Imbalance Party will be calculated;

(b) the basis on which Imbalance Parties may provide Credit Cover in respect of their Energy Indebtedness;

(d) circumstances which will constitute Credit Default in relation to an Imbalance Party, and the consequences of such Credit Default;

(e) arrangements for payment of compensation to Imbalance Parties in certain circumstances where errors have been made in calculations under this Section M.

1.2 Energy Indebtedness

1.2.1 For the purposes of the Code:

(a) in relation to a Settlement Period j the "Energy Indebtedness" (EI_pj, in MWh) of an Imbalance Party p shall be the algebraic sum of:

(i) the algebraic sum of Actual Energy Indebtedness for Imbalance Party p for those Settlement Days d within the twenty nine day period for which (at the Submission Deadline for Settlement Period j), the Submission Deadline has passed for the first Settlement Period of the Settlement Day following that on which the Settlement Calendar specifies that the Interim Information Settlement Run for Settlement Day d is to take place (but excluding those days for which, as a result of a delay in the Interim Information Settlement Run in accordance with Section T1.4, the ECVAA does not receive the Interim Information Settlement Run data from the SAA by the Submission Deadline for the first Settlement Period of the Settlement Day containing Settlement Period j);

(ii) the algebraic sum of Metered Energy Indebtedness for Imbalance Party p in relation to those Settlement Days d within the twenty nine day period for which paragraph 1.2.1(a)(i) does not apply, and for which (at the Submission Deadline for Settlement Period j), the Submission Deadline has passed for the first Settlement Period of the Settlement Day following that on which the Settlement Calendar specifies that the Credit Cover Volume Allocation Run for Settlement Day d is to take place; and

(iii) the algebraic sum of Credit Assessment Energy Indebtedness for Imbalance Party p in relation to that Settlement Period and all prior Settlement Periods in days falling within the twenty nine day period for which neither paragraphs 1.2.1(a)(i) or 1.2.1(a)(ii) applies;

(b) a reference to an Imbalance Party's Energy Indebtedness at any time is to its Energy Indebtedness in relation to the latest Settlement Period for which the Submission Deadline occurred before such time;

(c) in relation to a Settlement Period, the twenty nine day period means the period of twenty nine Settlement Days expiring on (and including) the Settlement Day which includes that Settlement Period;

(d) for the purposes of paragraph 1.2.1(a)(i), where (by the Submission Deadline for the first Settlement Period of the Settlement Day containing the Settlement Period j), the ECVAA has not received the Interim Information Settlement Run data from the SAA in accordance with Section T5.3.5 for any Settlement Day d within the twenty nine day period to which paragraph 1.2.1(a)(i) applies (other than as a result of a delay in the Interim Information Settlement Run in accordance with Section T1.4), the ECVAA shall use the Metered Energy Indebtedness for the Settlement Periods in that Settlement Day d but without prejudice to paragraph 4;

(e) for the purposes of paragraph 1.2.1(a)(ii), where (by the Submission Deadline for the first Settlement Period of the Settlement Day containing the Settlement Period j), the ECVAA has not received the Credit Cover Volume Allocation Run data from the CDCA in accordance with Section R5.7.1(d) for any Settlement Day d within the twenty nine day period to which paragraph 1.2.1(a)(ii) applies, the ECVAA shall use the Credit Assessment Energy Indebtedness for the Settlement Periods in that Settlement Day d but without prejudice to paragraph 4;

(f) in relation to an Imbalance Party and Settlement Day, where BSCCo:

(i) is aware that the ECVAA has not received relevant Interim Information Settlement Run data from the SAA in accordance with Section T5.3.5; or

(ii) is aware that the ECVAA has not received relevant Credit Cover Volume Allocation Run data from the CDCA in accordance with Section R5.7.1(d); or

(iii) has substantial evidence or other reasons to believe that the data to be derived from the Initial Settlement Run for that Imbalance Party and that Settlement Day are likely to be significantly different (in the context of that particular Imbalance Party) from the corresponding Interim Information Settlement Run data received by the ECVAA from the SAA in accordance with Section T5.3.5; or

(iv) has substantial evidence or other reasons to believe that the data to be derived from the Initial Volume Allocation Run for that Imbalance Party and that Settlement Day are likely to be significantly different (in the context of that particular Imbalance Party) from the corresponding Credit Cover Volume Allocation Run data received from the CDCA in accordance with Section R5.7.1(d);

the absence of such data or the likelihood of such a significant difference (as the case may be) may, if BSCCo so decides and to the extent that it materially affects matters, constitute a material doubt for the purposes of paragraph 3.4.3(a); and

(g) where an Imbalance Party elects to submit, to BSCCo, such evidence as is referred to in paragraph 1.2.1(f), BSCCo must review that evidence as soon as practicable after receiving it, but must verify any opinion formed in relation to such evidence as soon as practicable after receiving a level 1 default notice (in accordance with paragraph 3.2.1(a)(ii)) in relation to that Imbalance Party.

1.2.2 For the purposes of paragraph 1.2.1, the Credit Assessment Energy Indebtedness (CEI_pj, in MWh) of a Trading Party p in relation to a Settlement Period shall be determined as follows:

(a) the Imbalance Party shall give notice to that effect to the ECVAA;

(b) the ECVAA shall determine and notify to the FAA and the Imbalance Party, on the first Business Day after the expiry of the waiting period, the minimum eligible amount;

(c) the Imbalance Party may, not later than the second Business Day following the ECVAA's notification under paragraph (b), by notice to the FAA request, and the FAA on behalf of the BSC Clearer shall consent to:

(i) a reduction in the amount of a Letter of Credit or Approved Insurance Product provided by the Imbalance Party, and/or

(ii) a withdrawal of cash deposited by the Imbalance Party

provided that the amount of the Imbalance Party's Credit Cover following such reduction and/or withdrawal is not less than the minimum eligible amount and that that Imbalance Party is not in default of any obligation to make a payment to the BSC Clearer and (subject to paragraph 2.3.1(A) and 2.3A) is not a Defaulting Party (as defined in Section H3).

2.3.1A Where at any time an Imbalance Party:

(a) is in Default solely by virtue of Section H 3.1.1(g); and

(b) has given a Withdrawal Notice pursuant to Section A5.1 which remains effective; and

(c) is not prevented from withdrawing from the Code or ceasing to be a party to the Framework Agreement by virtue of Section A5.1.3,

then such Imbalance Party shall not be precluded from being entitled to:

(1) a reduction in the amount of a Letter of Credit or an Approved Insurance Product provided by it; and/or

(2) a withdrawal of cash deposited by it.

2.3.2 For the purposes of paragraph 2.3.1:

(a) the "waiting period" is the period of ten Settlement Days commencing with the Settlement Day on which the Imbalance Party's notice under paragraph 2.3.1(a) was received by the ECVAA;

(b) the "minimum eligible amount" is the lowest amount for which the Imbalance Party's Credit Cover Percentage, if it were redetermined for each Settlement Period in the waiting period on the assumption that the Imbalance Party's Credit Cover were equal to that amount, would be not greater than seventy five (75) per cent (%) in relation to any such Settlement Period.

2.3.3 If at any time:

(a) the ECVAA has given to an Imbalance Party a level 1 default notice which was not cancelled pursuant to paragraph 3.2.4, or notified an Imbalance Party that it is in Credit Default;

(b) following such notice or notification the Imbalance Party provided additional Credit Cover; and

(c) after the Imbalance Party provided additional Credit Cover, the ECVAA established that, or it is determined pursuant to Section W that, the level 1 default notice should not have been given or that the Imbalance Party was not in Credit Default.

then paragraph 2.3.4 shall apply.

2.3.4 In the circumstances described in paragraph 2.3.3:

(a) the Imbalance Party may reduce the amount of its Credit Cover, by an amount not exceeding the amount of the additional Credit Cover provided by it as referred to in paragraph 2.3.3(b), in accordance with paragraph 2.3, but on the basis that:

(i) the waiting period is a period of one Settlement Day;

(ii) the figure of eighty (80) per cent (%) is substituted for seventy five (75) per cent (%) in paragraph 2.3.2(b);

(b) except as provided in paragraph 4, the Imbalance Party shall have no other claim or remedy for having so provided additional Credit Cover.

2.3A Reduction of Credit Cover for Non-Supplier Trading Party

2.3A.1 Where a Non-Supplier Trading Party or a Virtual Lead Party which is in Default solely by virtue of Section H 3.1.1(g) wishes to reduce the amount of its Credit Cover it shall make a submission in writing.

2.3A.2 Following a request submitted in accordance with paragraph 2.3A.1, at the next Panel meeting following confirmation by BSCCo that the Non-Supplier Trading Party or a Virtual Lead Party meets the conditions set out in paragraph 2.3A.5 the Panel shall consider and take a decision as to whether there is any reason why the Non-Supplier Trading Party or a Virtual Lead Party should not be entitled to:

(a) a reduction in the amount of a Letter of Credit or Approved Insurance Product provided by the Non-Supplier Trading Party or a Virtual Lead Party; and/or

(b) a withdrawal of cash deposited by the Non-Supplier Trading Party or a Virtual Lead Party.

2.3A.3 At the time the Panel makes its decision:

(a) the amount of the Non-Supplier Trading Party or a Virtual Lead Party's Credit Cover following such reduction and/or withdrawal shall be the amount calculated in accordance with paragraph 2.3A.6; and

(b) the Non-Supplier Trading Party is a Trading Party or a Virtual Lead Party which is in Default solely by virtue of Section H.3.1.1(g); and

2.3A.4 If the Panel considers that there is insufficient information available to it to enable it to take the decision referred to in paragraph 2.3A.2 in respect of a request by the Non-Supplier Trading Party or a Virtual Lead Party for a reduction in Credit Cover then the Panel may defer consideration of the request until the next succeeding Panel meeting provided that, in so doing, the Panel shall prescribe the steps which need to be taken (by BSCCo, the Non Supplier Trading Party, Virtual Lead Party or otherwise) to enable the Panel to decide the matter at such subsequent meeting.

2.3A.5 In accordance with paragraph 2.3A.2 the Non-Supplier Trading Party or a Virtual Lead Party must meet each of the following conditions:

(a) at the date it gives notice pursuant to paragraph 2.3A.1:

(i) there are no Energy Contract Volume Notifications or Metered Volume Reallocation Notifications in force, in respect of which the Trading Party is a Contract Trading Party, relating to Settlement Periods after that date and containing Energy Contract Volume Data or Metered Volume Reallocation Data with non-zero values; and

(ii) the Non-Supplier Trading Party has terminated all ECVNA Authorisations and MVRNA Authorisations made under its authority;

and

(b) the Non-Supplier Trading Party or a Virtual Lead Party shall have paid any and all Trading Charges payable up to or on the Payment Date; and

(c) the Non-Supplier Trading Party or a Virtual Lead Party shall have paid any and all BSC Charges payable up to the date that it gives notice pursuant to paragraph 2.3A.1 in accordance with Section D Annex D4 and D5; and

(d) the Non-Supplier Trading Party or a Virtual Lead Party shall have completed de-registration (in accordance with Section K and BSCP15) from ownership of any BM Units for which it was registered by the date it gives notice pursuant to paragraph 2.3A.1; and

(e) the Non-Supplier Trading Party or a Virtual Lead Party shall have an Energy Indebtedness of zero or less than zero continuously over the period of thirty days immediately preceding to the giving of notice pursuant to paragraph 2.3A.1.

2.3A.6 Any reduction in or withdrawal of Credit Cover in relation to paragraph 2.3A shall be made in accordance with the following sum:

The amount of Credit Required (CR, in £) required by a Non-Supplier Trading Party or a Virtual Lead Party shall be calculated as follows:

_{$\sum_{x \in (1,2,3, F)} NRxSP * \frac{\sum_{Rx (j)} max ({RxC}_{j}, 0)}{RxSP}$}

where:

RxSP is the count of all Settlement Periods falling any time up to a year before the date on which the Non-Supplier Trading Party or a Virtual Lead Party in question ceased trading for which the Rx Reconciliation Run has been performed or if this number is less than 1440 (thirty days) then 1440.

ΣRx(j) represents summation over all Settlement Periods falling within a year before the date on which the Non-Supplier Trading Party or a Virtual Lead Party in question ceased trading for which the Rx Reconciliation Run has been performed or if the number of Settlement Periods in this sum is less than 1440, then the summation over the last 1440 Settlement Periods for which the Rx Reconciliation Run has been performed.

RxCj represents the Reconciliation Charges (as defined in Section N6.4.3) payable by the Non-Supplier Trading Party or a Virtual Lead Party (summed across its accounts) due to the Rx Reconciliation Run in the relevant Settlement Period.

NRxSP represents the count of all Settlement Periods up to and including the date on which the Non-Supplier Trading Party or a Virtual Lead Party ceased trading for which the Rx Reconciliation Run has not been performed.

For the purposes of paragraph2.3A the date that the Non-Supplier Trading Party or a Virtual Lead Party ceased trading shall be the earliest date on which there are no Energy Contract Volume Notifications or Metered Volume Reallocation Notifications in force in respect of which the Non-Supplier Trading Party or a Virtual Lead Party is a Contract Trading Party and there is no credited Energy in either the Production or Consumption Account of such Non-Supplier Trading Party or a Virtual Lead Party.

2.3A.7 For the purposes of paragraph 2.3A a Non-Supplier Trading Party shall be a Trading Party which is not:

(a) a Supplier; or

(b) a Subsidiary Party in a Metered Volume Reallocation Notification where the Lead Party in the Metered Volume Reallocation Notification was a Supplier where the percentage value is greater than zero;

and in all cases this shall have been the case for any Settlement Day for which a Final Reconciliation Settlement Run has not been performed.

2.3A.8 For the avoidance of doubt, paragraph 2.3.3 applies in connection with this paragraph 2.3A.

2.4 Determination of Energy Credit Cover

2.4.1 An Imbalance Party's "Energy Credit Cover" (ECC_p) at any time is the amount (in MWh) determined as:

CC_p / CAP

where:

CC_p is the amount of the Imbalance Party's Credit Cover at that time;

CAP is the Credit Assessment Price prevailing at such time.

2.4.2 The FAA shall:

(a) monitor the amount of each Imbalance Party's Credit Cover;

(b) determine in accordance with paragraph 2.4.1 the amount from time to time of each Imbalance Party's Energy Credit Cover;

(i) on the day on which that Party becomes an Imbalance Party; and

(ii) upon each occasion on which the amount of such Energy Credit Cover changes, as soon as reasonably practicable after becoming aware of the change.

2.4.3 For the purposes of this Section M, a reference to the amount of an Imbalance Party's Energy Credit Cover is to the amount most recently notified by the FAA to the ECVAA under paragraph 2.4.2(c) (or to an amount of zero if no such amount has been so notified).

2.4.4 For the purposes of paragraph 4, the time at which (upon a change as referred to in paragraph 2.4.2(c)(ii)) the correct amount of an Imbalance Party's Energy Credit Cover should be notified by the FAA to the ECVAA, shall be 17:00 hours on the Business Day after the change occurred, or such earlier time as the correct amount was actually so notified.

3. CREDIT DEFAULT STATUS

3.1 General

3.1.1 In relation to any Settlement Period, an Imbalance Party's "Credit Cover Percentage" (CCP_pj, %) is:

(a) where ECC_p does not equal zero:

CCP_pj = (EI_pj / ECC_p) * 100

(b) where ECC_p equals zero:

then,

if EI_pj = 0, then CCP_pj = 0

if EI_pj > 0, then CCP_pj = + 1000

if EI_pj < 0, then CCP_pj = - 1000

where

EI_pj is the Imbalance Party's Energy Indebtedness in relation to that Settlement Period;

ECC_p is the amount of the Imbalance Party's Energy Credit Cover most recently notified by the FAA under paragraph 2.4.2(c).

3.1.2 In relation to a Settlement Period, an Imbalance Party's Credit Cover Percentage "becomes" greater, or not greater, than a specified percentage where:

(a) such Credit Cover Percentage in relation to that Settlement Period is greater, or (as the case may be) not greater, than that percentage, and

(b) the Imbalance Party's Credit Cover Percentage in relation to the preceding Settlement Period was not greater, or (as the case may be) was greater, than that percentage.

3.1.3 Where under this Section M:

(a) the ECVAA is required or entitled to take any step in relation to any Settlement Period in which an Imbalance Party's Credit Cover Percentage becomes greater, or not greater, or less, than a specified percentage, and

(b) the ECVAA does not (within the time required under this Section M) take that step in relation to that Settlement Period

nothing in this Section M shall prevent the ECVAA from taking that step in relation to any later Settlement Period in relation to which that Imbalance Party's Credit Cover Percentage remains greater, or (as the case may be) not greater, or less, than the specified percentage.

3.1.4 The ECVAA will:

(a) for each Settlement Period, as soon as practicable after the Submission Deadline, determine the Credit Cover Percentage for each Imbalance Party; and

(b) for each Settlement Day, as soon as reasonably practicable after the end of the Settlement Day, notify each Imbalance Party of its Credit Cover Percentage as calculated in respect of the last Settlement Period in that Settlement Day.

3.2 Level 1 Credit Default

3.2.1 If in relation to any Settlement Period an Imbalance Party's Credit Cover Percentage, as determined by the ECVAA, becomes greater than eighty (80) per cent (%):

(a) the ECVAA shall, as soon as possible after the Submission Deadline:

(i) give notice ("level 1 default notice") to the Imbalance Party to that effect (in addition to the notification under paragraph 3.1.4); and

(ii) submit a copy of such notice to BSCCo; and

(b) the Imbalance Party may, at any time before the expiry of the Query Period, give notice ("default query notice") to the ECVAA that it considers that its Credit Cover Percentage has been determined erroneously, and may provide information supporting its view.

3.2.2 In relation to any level 1 default notice, the "Query Period" is the period commencing at the Submission Deadline for the Settlement Period in relation to which the ECVAA determines that the Imbalance Party's Credit Cover Percentage becomes greater than eighty (80) per cent (%) and ending after the shortest duration to include:

(a) twenty four hours; and

(b) five consecutive hours occurring during Business Hours in a single Business Day

after the time at which the level 1 default notice is treated as received by the Imbalance Party (in accordance with Section O).

3.2.3 If an Imbalance Party gives a default query notice to the ECVAA:

(a) the ECVAA shall, before the expiry of the Query Period, review its determination of the Imbalance Party's Credit Cover Percentage and if the Imbalance Party so requests, shall discuss the same by telephone with a representative of the Imbalance Party;

(b) if requested by the ECVAA, the Imbalance Party shall provide further information and explanation in support of its view that the ECVAA's determination of the Credit Cover Percentage was erroneous;

(c) at the expiry of the Query Period (and whether or not any consensus has been reached between the ECVAA and the Imbalance Party as to the matters notified by the Imbalance Party), the ECVAA will redetermine the Imbalance Party's Credit Cover Percentage for the relevant Settlement Period (and for the avoidance of doubt, such redetermination may be the same as its original determination), and will give notice to the Imbalance Party of the Credit Cover Percentage as redetermined;

(d) the ECVAA will correct its determination of the Imbalance Party's Credit Cover Percentage for any subsequent Settlement Period, so far as such determination is shown to be erroneous by reference to (or to the matters taken into account in) the ECVAA's redetermination under paragraph (c).

3.2.4 If the redetermined Credit Cover Percentage under paragraph 3.2.3(c) is not greater than eighty (80) per cent (%) the level 1 default notice will be deemed to be cancelled and no further action taken under this paragraph 3.2 in relation to Energy Indebtedness in the relevant Settlement Period (but without prejudice to the application of this paragraph 3.2 in relation to any later Settlement Period).

3.2.5 If the redetermined Credit Cover Percentage under paragraph 3.2.3(c) is greater than eighty (80) per cent (%), or if no default query notice was given, the Imbalance Party shall secure that its Credit Cover Percentage becomes not greater than seventy five (75) per cent (%) in relation to at least one Settlement Period in the period (the "Level 1 Credit Default Cure Period"):

(a) commencing on the expiry of the Query Period, and

(b) expiring at 2400 hours on the first Business Day after the day in which the Query Period expires.

3.2.6 At the end of the Level 1 Credit Default Cure Period, if the Credit Cover Percentage (as determined by the ECVAA in relation to each Settlement Period) was greater than seventy five (75) per cent (%) in relation to every Settlement Period in the Level 1 Credit Default Cure Period, then subject to an authorisation notice being in force in relation to that Imbalance Party pursuant to paragraph 3.4 (or if later, with effect from such notice being given):

(a) the Trading Party shall be in "Level 1 Credit Default";

(b) the ECVAA shall (as soon as reasonably practicable following the expiry of the Level 1 Default Cure Period) notify the Imbalance Party that it is in Level 1 Credit Default and post on the BMRS or the BSC Website a Level 1 Credit Default statement in relation to the Imbalance Party.

3.2.7 The Imbalance Party will cease to be in Level 1 Credit Default with effect from the Submission Deadline for the next Settlement Period (if any) in relation to which the Imbalance Party's Credit Cover Percentage becomes not greater than seventy five (75) per cent (%); and as soon as practicable after the Submission Deadline for that Settlement Period the ECVAA will cancel the Level 1 Credit Default statement on the BMRS or (as the case may be) the BSC Website.

3.3 Level 2 Credit Default

3.3.1 If, in relation to any Settlement Period (period J), an Imbalance Party's Credit Cover Percentage as determined by the ECVAA becomes greater than ninety (90) per cent (%), irrespective of whether or not Settlement Period J falls in a Query Period or a Level 1 Credit Default Cure Period (in accordance with paragraph 3.2), then subject to an authorisation notice being in force in relation to that Imbalance Party pursuant to paragraph 3.4 (or if later, with effect from such notice being given):

(a) the Imbalance Party shall be in "Level 2 Credit Default";

(b) the ECVAA shall, as soon as reasonably practicable after the Submission Deadline for Settlement Period J, notify the Imbalance Party that it is in Level 2 Credit Default and post a Level 2 Credit Default statement on the BMRS or the BSC Website in relation to the Imbalance Party.

3.3.2 The Imbalance Party will cease to be in Level 2 Credit Default with effect from the Submission Deadline for the next Settlement Period (if any) in relation to which the Imbalance Party's Credit Cover Percentage becomes not greater than ninety (90) per cent (%); and as soon as practicable after the Submission Deadline for that Settlement Period the ECVAA will cancel the Level 2 Credit Default statement on the BMRS or the BSC Website.

3.3.3 Where an Imbalance Party is in Level 2 Credit Default:

(a) for the purposes of the provisions of Section P as to the refusal and rejection of Energy Contract Volume Notifications and Metered Volume Reallocation Notifications, subject to paragraph 3.3.5:

(i) the "Credit Default Refusal Period" is the period from the Submission Deadline for Settlement Period J+4 until the Submission Deadline for the Settlement Period after the first subsequent Settlement Period in relation to which the Credit Cover Percentage for the Imbalance Party becomes not greater than ninety (90) per cent (%);

(ii) the "Credit Default Rejection Period" is the period from the Submission Deadline for Settlement Period J+4 until the Submission Deadline for the third Settlement Period after the first subsequent Settlement Period in relation to which the Credit Cover Percentage for the Imbalance Party becomes not greater than ninety (90) per cent (%);

(b) as soon as reasonably practicable after the Submission Deadline for Settlement Period J, the ECVAA will post on the BMRS or (as the case may be) the BSC Website a notice of the start of the Credit Default Rejection Period in relation to the Imbalance Party (but a failure to post such notice will have no effect in relation to the start of the Credit Default Rejection Period).

3.3.4 For the purposes of paragraph 3.3.3, a relevant Query Period is the Query Period in relation to any Settlement Period, not later than Settlement Period J, for which the Imbalance Party had given a default query notice.

3.3.5 The following provisions apply for the purposes of addressing delays in the completion of credit checking (and references in the Code to Credit Default Refusal Periods and Credit Default Rejection Periods shall be construed accordingly):

(a) a Credit Default Refusal Period and a Credit Default Rejection Period shall not commence if credit checking for Settlement Period J is not completed by the half-hour deadline, but without prejudice to paragraph 3.1.3;

(b) a Credit Default Refusal Period excludes the period from the Submission Deadline for Settlement Period J until credit checking for that Settlement Period is completed;

(c) a Credit Default Refusal Period excludes the period (if any) from completion of credit checking for the Submission Deadline for the first subsequent Settlement Period referred to in paragraph 3.3.3(a)(i) until the half-hour deadline;

(d) if a Credit Default Refusal Period has commenced and credit checking for any Settlement Period has not been completed by the half-hour deadline, the Credit Default Refusal Period shall be suspended (and accordingly exclude the period) from the time at which the ECVAA determines that credit checking has not been completed by the half-hour deadline, until such time as credit checking for a Settlement Period is completed by the half-hour deadline;

(e) if a Credit Default Rejection Period has commenced and credit checking for any Settlement Period (the "relevant" Settlement Period) has not been completed by the half-hour deadline, the Submission Deadline for the third Settlement Period after the relevant Settlement Period shall be considered (for the purposes of the Code including Sections P2.5.2 and P3.5.2) not to fall within the Credit Default Rejection Period.

3.3.6 For the purposes of paragraph 3.3.5, in relation to each Settlement Period:

(a) completion of credit checking means the time (determined by the ECVAA) at which the ECVAA completes the determination, for each Imbalance Party, of Credit Cover Percentage pursuant to paragraph 3.1.4(a); and references to credit checking being completed shall be construed accordingly;

(b) references to a case in which credit checking is not completed by the half-hour deadline include a case where the ECVAA has earlier determined that it will be unable to complete credit checking by that deadline;

(c) if requested by BSCCo in relation to any Settlement Period, the ECVAA will inform BSCCo of the time of completion of credit checking;

(d) the half-hour deadline means the time of the Submission Deadline for the following Settlement Period.

3.3.7 Without prejudice to paragraph 3.1.3, where an Imbalance Party has not been treated as in Level 2 Credit Default in relation to a Settlement Period, irrespective of any error made by the ECVAA in the application of the provisions of this Section M, no Party may raise a Trading Dispute to the effect that the Imbalance Party should have been treated as being in Credit Default or that a Credit Default Refusal Period or Credit Default Rejection Period should have commenced in relation to the Imbalance Party.

3.3.8 Not used.

3.3.9 Not used.

3.3.10 Not used.

3.3.11 If in relation to any Settlement Period an Imbalance Party's Credit Cover Percentage, as determined by the ECVAA, becomes greater than one hundred (100) per cent (%) the ECVAA shall as soon as reasonably practicable after the Submission Deadline:

(a) give a notice to the Imbalance Party which states that Imbalance Party's Credit Cover Percentage and alerts it to the provisions of Section H3.1.1(c); and

(b) submit a copy of such notice to BSCCo.

3.3.12 For the avoidance of doubt:

(a) the application of paragraph 3.3.11 to an Imbalance Party in relation to a Settlement Period shall not have the affect of excluding the application of any other relevant paragraph of Section M in relation to that Imbalance Party in that Settlement Period; and

(b) any failure or delay by the ECVAA to give a notice required by paragraph 3.3.11 shall not be taken into account for the purposes of determining the expiry of any of the time periods specified in Section H3.1.1(c).

3.4 Authorisation by BSCCo

3.4.1 In accordance with paragraphs 3.2.6 and 3.3.1, an Imbalance Party will not be in Credit Default unless:

(a) BSCCo has given to the ECVAA an authorisation notice in relation to that Imbalance Party; and

(b) the authorisation notice remains in force.

3.4.2 For the purposes of this Section M, an "authorisation notice" is a notice authorising the ECVAA, at any time while the notice is in force, to take the steps referred to in paragraph 3.2.6(b) and 3.3.1(b) in relation to an Imbalance Party.

3.4.3 Subject to paragraph 3.4.3A, where the ECVAA submits to BSCCo a copy of a level 1 default notice under paragraph 3.2.1 in relation to an Imbalance Party:

(a) BSCCo shall promptly upon the earlier of:

(i) the expiry of the Query Period during which the relevant Imbalance Party's Credit Cover Percentage becomes greater than ninety (90) percent (%);

(ii) the expiry of the Submission Deadline for Settlement Period J falling within a Level 1 Credit Default Cure Period during which the relevant Imbalance Party's Credit Cover Percentage becomes greater than ninety (90) per cent (%);

(iii) not used; or

(iv) the expiry of a Level 1 Credit Default Cure Period during which the relevant Imbalance Party's Credit Cover Percentage becomes not greater than ninety (90) per cent (%),

give an authorisation notice to the ECVAA unless:

(1) BSCCo has been notified by the ECVAA that in the ECVAA's opinion there is, or

(2) BSCCo otherwise has substantial evidence that, or other reasons to believe that, there is

(in accordance with paragraph 1.2.1(e) and the prevailing principles or guidance established by the Panel in accordance with paragraph 1.7) a material doubt as to whether, at the time, the systems and processes used by the ECVAA are giving correct determinations of the values of Credit Cover Percentage for that Imbalance Party;

(b) subject to paragraph (c), BSCCo shall not be required to make any enquiry of the Imbalance Party or any other person (but in accordance with paragraph 1.2.1(f) will take into account any information already provided by the Imbalance Party which is relevant to the matter in paragraph (a));

(i) BSCCo shall investigate the matter; and

(ii) if at any time it concludes that there is not (or no longer is) any material doubt as to the matter in paragraph (a), BSCCo shall promptly give the authorisation notice.

3.4.3A BSCCo shall not give an authorisation notice to the ECVAA in relation to an Imbalance Party under paragraph 3.4.3 if:

(a) Section G4 applies to that Imbalance Party; and

(b) that Imbalance Party’s Credit Cover Percentage is greater than eighty (80) per cent (%) as a direct result of it being subject to a direction given by the Secretary of State or action taken on behalf of His Majesty’s Government.

3.4.3B If paragraph 3.4.3A applies:

(a) BSCCo shall investigate the matter; and

(b) if at any time it concludes that the fact that the Imbalance Party’s Credit Cover is greater than eighty (80) per cent (%) is not (or no longer is) the direct result of a direction from the Secretary of State or action taken on behalf of His Majesty’s Government, BSCCo shall promptly give the authorisation notice under paragraph 3.4.3(a).

3.4.3C BSCCo shall not give an authorisation notice to the ECVAA in relation to an Imbalance Party under paragraph 3.4.3(a) if:

(a) that Imbalance Party is the Lead Party or Subsidiary Party of a BM Unit to which Section G6 applies; and

(b) that Imbalance Party’s Credit Cover Percentage is greater than eighty (80) per-cent (%) as a direct result of the BM Unit being subject to a Network Gas Supply Emergency Acceptance.

3.4.3D If paragraph 3.4.3C applies:

(a) BSCCo shall investigate the matter; and

(b) if at any time it concludes that the Imbalance Party’s Credit Cover being greater than eighty (80) percent (%) is not (or no longer is) the direct result of a Network Gas Supply Emergency Acceptance, BSCCo shall promptly give the authorisation notice under paragraph 3.4.3(a).

3.4.4 An authorisation notice shall remain in force until such time as:

(a) it is established or determined (as provided in paragraph 3.5.1) that the Credit Cover Percentage of Imbalance Party was not and has not since become greater than eighty (80) percent (%); or

(b) the ECVAA notifies BSCCo that the Imbalance Party's Credit Cover Percentage has become lower than seventy five (75) percent (%) for any Settlement Period after the authorisation notice was given; or

(c) BSCCo in its discretion determines that (as a result of the passage of time, or because of any other matter of which notice has been given to BSCCo) the authorisation notice should lapse, and gives notice to that effect to the ECVAA.

3.4.5 For the avoidance of doubt, paragraph 3.4.3 is without prejudice to the ability of a Party to raise a Trading Dispute in respect of any step taken or determination made by BSCCo or the ECVAA pursuant to this Section M.

3.4.6 Notwithstanding any other provision of this Section M, BSCCo shall and shall be treated as having refused to give to the ECVAA any authorisation notice in relation to the Replacement Supplier in respect of any Settlement Period for which the Submission Deadline falls within the first fourteen days after the Appointment Day for such Replacement Supplier (counting the Appointment Day itself for these purposes).

3.5 Result of Trading Dispute, etc

3.5.1 If at any time a Imbalance Party has been treated as in Credit Default, and it is established or pursuant to the resolution of a Trading Dispute determined that (by reason of such Imbalance Party's Credit Cover Percentage having been erroneously determined or otherwise) such Imbalance Party should not have been so treated:

(a) with effect as soon as practicable following the resolution of such Trading Dispute, BSCCo will post a notice on the BMRS or the BSC Website or both, referring to the relevant notices of Credit Default and stating that the Imbalance Party should not have been in Credit Default;

(b) the ECVAA shall take account of such determination in the further application (in relation to Settlement Periods after such resolution) of this Section M in respect of that Imbalance Party;

(c) the determination that the Imbalance Party should not have been treated as in Credit Default shall not affect or prejudice:

(i) the treatment (as refused or rejected) of any Energy Contract Volume Notifications or Metered Volume Reallocation Notifications which were treated as refused during the relevant Credit Default Refusal Period or treated as rejected during the relevant Credit Default Refusal Period, and no adjustment or reconciliation shall be made in respect thereof;

(ii) any other step taken under the Code while the Party was treated as in Credit Default,

but subject thereto, the Imbalance Party shall be treated for the purpose of the Code as never having been in Credit Default;

(d) the Imbalance Party shall have no other right or remedy in respect thereof except as described in paragraph (a) and (b) and pursuant to paragraph 4 where applicable.

3.6 BMRS and BSC Website

3.6.1 Provisions of this Section M requiring any statement or notice to be posted or cancelled on the BMRS or the BSC Website shall be subject to the provisions of Section V4.

4. CREDIT COVER ERRORS AND COMPENSATION

4.1 Introduction

4.1.1 If an Imbalance Party's Credit Cover Percentage is incorrectly determined and as a result a level 1 default notice was given to the Imbalance Party and/or the Imbalance Party was in Credit Default, the Imbalance Party shall be entitled to be paid compensation ("Credit Cover Error Compensation") subject to and in accordance with the further provisions of this paragraph 4.

4.1.2 Any Credit Cover Error Compensation paid to an Imbalance Party pursuant to this paragraph 4 shall be paid by BSCCo and accordingly shall be a BSC Cost; provided that BSCCo shall not be required to include any amount in respect of such compensation in the Annual Budget or to revise the Annual Budget if any such compensation becomes payable.

4.1.3 The provisions of this paragraph 4 are independent of any provision of a BSC Agent Contract pursuant to which any amount may be payable (by way of damages, liquidated damages, service credit or otherwise) in respect of the circumstances resulting in a Credit Cover Error; and it is acknowledged and agreed that any such amount will be paid to BSCCo and will accordingly reduce BSC Costs.

4.1.4 For the purposes of this paragraph 4:

(a) there is a "Credit Cover Error" where the Credit Cover Percentage determined (in the application of paragraph 3) for an Imbalance Party in respect of any Settlement Period was incorrect, and as a result (in relation to that or any earlier Settlement Period) a level 1 default notice was given to the Imbalance Party or the Imbalance Party was in Level 2 Credit Default;

(b) in relation to a Credit Cover Error

(i) the "first error" Settlement Period is the first Settlement Period in relation to which the Credit Cover Error occurred (in other words, for which the incorrect Credit Cover Percentage was determined as described in paragraph (a));

(ii) the "Credit Cover Error Period" is the period commencing on the earlier of:

(1) in relation to the first error Settlement Period, the expiry of the Query Period (the "error" Query Period) , and

(2) where as a result of the Credit Cover Error the Imbalance Party was determined to be in Level 2 Credit Default, the start of the Credit Default Rejection Period

and continuing until the first Settlement Period (after the Credit Cover Error has been corrected) for which the Imbalance Party's Credit Cover Percentage Energy is determined (in the application of paragraph 3) without such error.

4.2 Credit Cover Error Compensation

4.2.1 The amount of Credit Cover Error Compensation (CCEC_p, in £) payable to an Imbalance Party in respect of a Credit Cover Error shall be determined as follows:

CCEC_p = Σ_j max (ECA_pj, ECB_pj, 0)

where:

Σ_j is summation over all Settlement Periods falling within the Credit Cover Error Period;

ECA_pj is the Credit Cover Error Interest Amount, determined in accordance with paragraph 4.2.2;

ECB_pj is the Credit Cover Error Imbalance Amount, determined in accordance with paragraph 4.2.3.

4.2.2 For a Settlement Period within the Credit Cover Error Period, ECA_pj shall be determined as follows:

ECA_pj = {0.02 / (365 * 48)} * CAP * {( EEI_pj / 0.8 ) – max (IECC_p, ( EI_pj / 0.8 ))}

where:

EEI_pj (Erroneous Energy Indebtedness) is an amount (in £), determined as:

(i) (ECC_p * CCP_pj), or

(ii) if ECC_p is zero, EI_pj

in respect of the first error Settlement Period, as incorrectly determined or redetermined (on the basis of the Credit Cover Error) in the application of paragraph 3 as at the expiry of the error Query Period;

IECC_p (Initial Energy Credit Cover) is the correct amount of the Imbalance Party's Energy Credit Cover as at the Submission Deadline for the first error Settlement Period;

EI_pj is the Imbalance Party's Energy Indebtedness for Settlement Period j, as correctly determined after the Credit Cover Error was corrected.

4.2.3 For a Settlement Period within the Credit Cover Error Period, ECB_pj shall be determined as follows:

ECB_pj = (SBP_j – SSP_j) * Σ_a min (REJ_aj, QAEI_aj) * FLAG_pj

where:

Σ_j is summation over both Energy Accounts of the Imbalance Party;

REJ_aj (Credit Cover Error Rejection Volume) is the volume (in MWh) determined for Energy Account a of the Imbalance Party as the sum of:

(i) the sum of the Energy Contract Volume Data specified in Energy Contract Volume Notifications for which the Imbalance Party holds the Energy (From) Account less the sum of Energy Contract Volume Data specified in Energy Contract Volume Notifications for which the Imbalance Party holds the Energy (To) Account,

(ii) the aggregate of the Metered Volume Reallocation Fixed Data, and the aggregate amount determined in accordance with paragraph 4.2.5 in respect of Metered Volume Reallocation Percentage Data, which was the subject of Metered Volume Reallocation Notifications;

which (pursuant to Section P2.5.2 or P3.5.2) were treated as rejected and ineffective in respect of Settlement Period j by reason of there being a Credit Default Rejection Period in respect of the Imbalance Party;

FLAG_pj shall have the value 1 if the condition in paragraph 4.2.4 is satisfied and otherwise the value zero.

4.2.4 The condition (in relation to Settlement Period j) is that, if the Imbalance Party's Credit Cover Percentage had been correctly determined (with the Credit Cover Error corrected), but otherwise assuming that all steps and notifications (by the ECVAA and BSCCo) under paragraphs 3.3 and 3.4 had been taken in accordance with that paragraph, Settlement Period j would not have fallen within a Credit Default Rejection Period.

4.2.5 The value of REJ_aj (so far as relating to Metered Volume Reallocation Percentage Data) shall be determined:

(a) by reference to the formula in Section T4.5.1 by which Credited Energy Volume is determined, but assuming a value of one for the term TLM_ij and disregarding the term QMFR_iaj in that formula; and

(b) by reference to BM Unit Metered Volumes as determined in the Volume Allocation Run (for the Settlement Period j) most recently carried out before the date upon which the Imbalance Party submits its claim under paragraph 4.3.1(a).

4.3 Procedures

4.3.1 A Imbalance Party shall not be entitled to be paid Credit Cover Error Compensation:

(a) unless the Imbalance Party has submitted a claim for such compensation to BSCCo, within a period of three months after the Settlement Day in which the first error Settlement Period fell, setting out the amount which the Imbalance Party considers to be so payable and the basis on which the Imbalance Party has calculated such amount;

(b) if the amount which would be payable by way of Credit Cover Error Compensation (determined for the whole of the Credit Error Period) is less than one thousand pounds sterling (£1,000).

4.3.2 BSCCo shall determine and make payment of the amount payable by way of Credit Cover Error Compensation to an Imbalance Party as soon as reasonably practicable after the Imbalance Party submits its claim under paragraph 4.3.1(a).

4.3.3 The ECVAA shall provide all such assistance and information as BSCCo may reasonably require to enable it to determine any amount payable by way of Credit Cover Error Compensation.

SECTION N: CLEARING, INVOICING & PAYMENT

1. INTRODUCTION

1.1 General

1.1.1 This Section N sets out:

(a) the means by which the BSC Clearer will receive from, or pay to, each Payment Party an amount in respect of Trading Charges and Reconciliation Charges on each Payment Date;

(b) data requirements of, and procedures to be followed by, the FAA in order to determine and notify to Payment Parties the amounts payable by them in respect of Trading Charges and Reconciliation Charges;

(c) procedures for the FAA and Payment Parties to facilitate and make payments in respect of Trading Charges and Reconciliation Charges;

(d) the obligations of Payment Parties and the BSC Clearer to make payments in respect of Trading Charges and Reconciliation Charges, and consequences of any of them failing to make such payment; and

(e) the basis on which amounts paid in respect of Trading Charges and Reconciliation Charges, and on which Credit Cover provided in accordance with Section M, will be held by the BSC Clearer.

1.1.2 For the avoidance of doubt, this Section N applies in relation to Trading Charges, Reconciliation Charges and other payments due from Parties pursuant to this Section N only and not to any BSCCo Charges or other payments due from Parties pursuant to the Code.

2. CLEARING ARRANGEMENTS

2.1 General

2.1.1 In this paragraph 2:

(a) references to a Party are to an Imbalance Party or the NETSO and do not include the BSC Clearer; and

(b) references to a Defaulting Party are to a Party in relation to whom:

(i) a Default within Section H3.1.1 (g) has occurred;

(ii) a notice within Section H3.2.1(f) has been received by the FAA on behalf of the BSC Clearer; or

(iii) a Default within Section H3.1.1 (h) has occurred.

2.2 The BSC Clearer as counter party to each Party

2.2.1 Each Party shall be entitled to receive from the BSC Clearer (and not from any other Party), and shall be obliged to pay to the BSC Clearer (and not to any other Party), amounts (pursuant to the Code) in respect of Trading Charges and Reconciliation Charges (determined pursuant to paragraphs 2.8.2 and 6.4.2 and including Ad-hoc Trading Charges in accordance with paragraph 6.9.1(b)) and the BSC Clearer shall be correspondingly obliged and entitled.

2.2.2 The BSC Clearer’s obligations to pay amounts in respect of Trading Charges and Reconciliation Charges (determined pursuant to paragraphs 2.8.2 and 6.4.2 and including Ad-hoc Trading Charges in accordance with paragraph 6.9.1(b)) shall be subject to the provisions of paragraphs 2.4 to 2.7 (inclusive).

2.3 Determination of payments for Trading Charges

2.3.1 The obligation to pay an amount in respect of Trading Charges for a Settlement Day shall be calculated in accordance with Section T so that there is one obligation to pay an amount (if any) in respect of those Trading Charges.

2.4 Payment netting

2.4.1 If, on any Business Day, amounts in respect of Trading Charges (determined in accordance with paragraph 2.3 and, where applicable, paragraph 6.10), amounts in respect of Reconciliation Charges (determined in accordance with paragraphs 2.8.2 and 6.4.2 and including Ad-hoc Trading Charges in accordance with paragraph 6.9.1(b)) and amounts in respect of interest (determined in accordance with paragraph 4.6.3) would otherwise be payable by each of a Party and the BSC Clearer to the other, then the obligations to make payment of such amounts will automatically be cancelled and replaced by a single obligation upon the Party or the BSC Clearer (as the case may be) who would have had to pay the larger aggregate amount to pay the net amount (if any) to the other.

2.5 Conditions for payment by the BSC Clearer

2.5.1 Subject to paragraph 2.5.2 and 2.5.6, a Party shall be entitled to payment from the BSC Clearer on a Business Day if, and only if, on that Business Day there is no Amount in Default (as defined in paragraph 9.1(a)) due and payable by that Party to the BSC Clearer and not paid or recovered (within the meaning of paragraph 9.3.1) and so long as an Amount in Default, or any part of it, remains owing to the BSC Clearer, that Party will not request, demand or claim to be entitled to payment by the BSC Clearer.

2.5.2 Subject to paragraph 2.5.4 and paragraph 2.5.5 as the case may be, a Defaulting Party shall be entitled to payment from the BSC Clearer if, and only if, all amounts, liabilities and other obligations due, owing, incurred or payable by that Defaulting Party to the BSC Clearer, whether those liabilities or obligations are actual or contingent, present or future, joint or several (including, without limitation, all interest (after as well as before judgment) and expenses) have been paid or recovered and until that time the Defaulting Party will not request, demand or claim to be entitled to payment by the BSC Clearer.

2.5.3 The FAA on behalf of the BSC Clearer shall credit to the Reserve Account amounts due and payable to a Defaulting Party which:

(a) are unpaid pursuant to paragraph 2.5.1 and are not set off under paragraph 2.6; or

(b) are unpaid pursuant to paragraph 2.5.6,

and while any such amount is credited to the Reserve Account, it shall form part of the relevant Party’s Credit Cover and may be applied by the FAA on behalf of the BSC Clearer in accordance with this Section N.

2.5.4 Where at any time a Defaulting Party:

(i) is in Default solely by virtue of Section H3.1.1 (g);

(ii) has given a Withdrawal Notice pursuant to Section A5.1 that continues to be effective; and

(iii) is not prevented from withdrawing from the Code or from ceasing to be a Party to the Framework Agreement by virtue of Section A5.1.3;

then references to amounts, liabilities and other obligations of such Defaulting Party in paragraph 2.5.2 shall not include amounts, liabilities and obligations of a contingent nature.

2.5.5 Where at any time the Panel has determined in accordance with section M2.3A that an Imbalance Party is entitled to:

(a) a reduction in the amount of a Letter of Credit provided by the Imbalance Party, and/or

(b) a withdrawal of cash deposited by the Imbalance Party

then references to amounts, liabilities and other obligations of such Imbalance Party in paragraph 2.5.2 shall not include amounts, liabilities and obligations of a contingent nature.

2.5.6 Where the right of a Defaulting Party to receive payment has been suspended under Section H3.2.2(h), no amount becoming due and payable (pursuant to this Section N) to such Defaulting Party shall be paid by the BSC Clearer to such Defaulting Party (or to any person to whom the Defaulting Party may have assigned or transferred any of its rights pursuant to the Code).

2.6 Set-off

2.6.1 If on any Business Day an amount is due and would but for paragraph 2.5 have been payable from the BSC Clearer to a Party, but before that Business Day there was due from that Party an Amount in Default (as defined in paragraph 9.1(a)) which has not been paid or recovered (within the meaning of paragraph 9.3.1) then notwithstanding paragraph 2.5, the amount owing by the BSC Clearer shall be automatically and unconditionally set off against the Amount(s) in Default.

2.6.2 If in respect of any Non-paying BSC Debtor there is more than one Amount in Default, then any amount due and payable from the BSC Clearer shall be set off against the Amounts in Default in the order in which they originally became due and payable.

2.7 Liability of the BSC Clearer

2.7.1 The liability of the BSC Clearer to make payments on a Business Day under the Code shall be limited so that the aggregate of such payments (excluding the amount (if any) by which each such payment has been increased on account of VAT) does not exceed the aggregate amount of payments (excluding the amount (if any) by which each such payment has been increased on account of VAT) that has been paid to or recovered (within the meaning of paragraph 9.3.1) by the BSC Clearer:

(a) from Parties (including by way of realisation of Credit Cover in accordance with paragraph 9), in respect of that Business Day; and

(b) by way of a Drawing, but only where this Section N provides for such a Drawing to be made, and without prejudice to the further payment obligations of Parties arising following any such Drawing;

and each Party irrevocably and unconditionally releases the BSC Clearer from any other liability in respect of that Business Day other than as provided in this paragraph 2.7.1 and paragraph 2.7.2(b).

2.7.2 Where in relation to any Business Day, the aggregate amount that the BSC Clearer pays to Parties is less than the amount to which those Parties would, but for the operation of paragraph 2.7.1, have been entitled:

(a) the provisions of paragraph 9 shall apply; and

(b) if and to the extent that, after the required time on the Business Day, the BSC Clearer is paid and recovers (within the meaning of paragraph 9.3.1) amounts from any BSC Debtor, the BSC Clearer shall to the extent of such receipts make payments (to certain Parties and/or the BSC Banker) in accordance with the provisions of paragraph 9.

2.7.3 Any amounts in respect of VAT that the BSC Clearer is required to pay to Parties on a Business Day under the Code shall be funded:

(a) by amounts that it receives in respect of VAT from Parties under the Code on that Business Day; and

(b) by way of a Drawing, but:

(i) only where this Section N provides for such a Drawing to be made;

(ii) without prejudice to the further payment obligations of Parties arising following any such Drawing; and

(iii) only to the extent that the amount of such a Drawing represents the part of the Amount in Default that is attributable to VAT;

and where such amounts are insufficient BSCCo shall, in advance in accordance with paragraph 7.1.4 or, where such amount is insufficient due to the occurrence of an Amount in Default, as soon as reasonably practicable, fund the excess provided that the BSC Clearer shall only be required to pay that excess as and when it receives such funding from BSCCo.

2.8 Trading Disputes

2.8.1 For the avoidance of doubt, nothing in this paragraph 2 shall prevent a Party from raising Trading Disputes.

2.8.2 It is acknowledged and agreed that, where any dispute or difference arises under the Code as to any amount paid or payable by any Party by way of Trading Charge:

(a) where such dispute or difference is resolved, any necessary payments or adjustments required in order to give effect to such resolution (including any arbitral award) shall be effected (and may be given full effect) by way of Reconciliation Settlement Run, giving rise to new Reconciliation Charges, or by way of Ad-hoc Trading Charges under paragraph 6.9.1(a)(ii); and

(b) it is not necessary (in order to enable such dispute or difference to be resolved) for the BSC Clearer to participate in any Trading Dispute under Section W, or to be party to any arbitration pursuant to Section H7;

and accordingly no Party shall commence any proceedings against the BSC Clearer in relation to any such dispute or difference or seek to join or involve the BSC Clearer in any such proceedings.

2.8.3 If, notwithstanding paragraph 2.8.2, a Party commences proceedings against the BSC Clearer:

(a) all costs of the BSC Clearer shall be paid by BSCCo; and

(b) any award against the BSC Clearer shall be paid by BSCCo unless the terms of the award are to the effect that other Parties should pay or be liable for the award in which case such other Parties shall indemnify the BSC Clearer accordingly.

2.9 Assignment

2.9.1 Subject to the provisions of paragraphs 2.4 to 2.7 (inclusive), nothing in this paragraph 2 shall prevent Parties from assigning by way of security only any or all of their rights to receive from the BSC Clearer amounts determined in accordance with this paragraph 2 or in accordance with any other provision of this Section N.

(ii) the Initial Notification Date;

for each such Settlement Day in the next following BSC Year, and

4. BANKING ARRANGEMENTS

4.1 Establishment of Accounts

4.1.1 The FAA shall establish and operate on behalf of the BSC Clearer the following accounts (each a "BSC Account") in the name of the BSC Clearer:

(a) a Clearing Account with the BSC Banker to and from which all payments determined in accordance with this Section N are to be made;

(e) any other account that the FAA (with the prior written consent of BSCCo) considers desirable to enable the BSC Clearer to perform any obligations imposed on it by this Section N.

For the avoidance of doubt the Clearing Account and Collection Account referred to in 4.1.1(a) and 4.1.1 (b) above can be one and same account.

4.1.2 The FAA shall also establish on behalf of the BSC Clearer the means by which to facilitate and manage the transfer of Reserve Account monies between the Reserve Account and an Investment Account(s).

4.2. Funds Transfer Agreement

4.2.1 Not later than the date required by paragraph 4.2.3, the BSC Clearer and the FAA shall enter into a funds transfer agreement, in a form approved by the Panel, with a bank (the "BSC Banker") approved by the Panel, which shall set out the accounts opened in the name of the BSC Clearer and the basis on which the FAA shall operate them.

4.6 Reserve Account

4.6.1 Where an Imbalance Party provides Credit Cover by delivering cash (as contemplated by Section M) that Cash Cover shall be:

(a) credited to the Reserve Account (an account in the name of the BSC Clearer);

(b) the absolute property of the BSC Clearer (and the relevant Imbalance Party shall have no beneficial or other interest in the Cash Cover); and

(c) a limited recourse loan to the BSC Clearer which is repayable only in the circumstances set out in paragraph 4.6.3 and subject to the provisions of this Section N.

4.6.2 The purpose of the Cash Cover is to ensure that, on a continuing basis and for so long as the Imbalance Party is not a Discontinuing Party, the BSC Clearer is a debtor to the relevant Imbalance Party and in calculating the amounts due either from the BSC Clearer to the Imbalance Party or from the Imbalance Party to the BSC Clearer in accordance with this Section N, the amount of the Cash Cover shall be ignored.

4.6.3 The FAA on behalf of the BSC Clearer shall pay or repay the following amounts at the times indicated from the Reserve Account to each Payment Party:

(a) (subject to paragraph 4.6.6) quarterly the amount of interest referred to in paragraph 4.6.4;

4.6.4 The amount of interest is:

(a) an amount equal to interest from time to time received which is proportionate to the amount of monies deposited by the Payment Party from time to time in the Reserve Account; and

(b) credited to the Reserve Account and not subsequently withdrawn, repaid or set off in accordance with this Section N.

4.6.5 The BSC Clearer’s obligation to repay amounts under this paragraph 4.6 shall be subject to the provisions of paragraphs 2.4 to 2.6 (inclusive).

4.6.6 While any interest is credited to the Reserve Account, it shall be deemed to form part of the relevant Party’s Credit Cover for the purposes of this Section N only (and not for the purposes of Section M2.1.3 or any other section of the Code) and may be applied by the FAA on behalf of the BSC Clearer in accordance with this Section N.

4.6.7 Each Payment Party waives any right and agrees not to make any claim it might otherwise have to set off against any obligation owing to the BSC Clearer any claims such Payment Party may have to repayment of moneys paid to the BSC Clearer and credited to the Reserve Account.

4.9.1 The BSC Clearer shall enter into a facility agreement, in a form approved by the Panel, with the BSC Banker pursuant to which the BSC Banker shall make available to the BSC Clearer not later than the date required by paragraph 4.9.2 a facility of a maximum aggregate principal amount outstanding of four million pounds sterling (£4,000,000) or such other amount (but subject to a maximum amount of ten million pounds sterling (£10,000,000)) approved by the Panel from time to time for the purpose set out in paragraph 4.9.3 below.

4.9.2 If an existing Credit Facility will not be extended or renewed, the required date shall be upon the expiry of that Credit Facility.

4.9.3 The purpose of the Credit Facility is to cover banking and payment errors and short-term payment defaults and to minimise the need to use Credit Cover provided by Payment Parties in accordance with this Section N and the Credit Facility shall not be used for any other purpose.

4.9.4 All fees and expenses properly due from the BSC Clearer to the BSC Banker (including any additional amounts payable to the BSC Banker under the terms of the Credit Facility which the FAA on behalf of the BSC Clearer has not been able to pay after acting in accordance with paragraph 9) shall be paid by BSCCo on behalf of the BSC Clearer on the date the fees or expenses are payable to the BSC Banker.

4.9.5 The FAA on behalf of the BSC Clearer shall notify BSCCo and all Payment Parties of, and any changes in, the interest rate notified by the BSC Banker under the Credit Facility to it from time to time.

4.9.6 The FAA on behalf of the BSC Clearer shall:

(a) notify BSCCo forthwith on:

(i) becoming aware of any circumstances which may lead to the BSC Banker withdrawing the Credit Facility;

(ii) receiving a written demand from the BSC Banker as a result of which the Credit Facility ceases to become available;

(iii) receiving notice from the BSC Banker that it requires any additional amount to be paid to it as a result of any change in circumstances or any increased costs; and

5. TAXATION

5.1 Tax Agreements

5.1.1 Each Payment Party agrees that it will be bound by any agreement made (whether before or after the entry into force of the Code) between the BSC Clearer (or BSCCo on its behalf) and any tax authority as to the treatment for taxation purposes of obligations to pay amounts (pursuant to the Code) in respect of Trading Charges between the BSC Clearer and any Payment Party.

5.1.2 Each Payment Party further undertakes that it will not act in any way prejudicial to such agreement, including acting on the basis of, assuming, seeking or making any application or request to any tax authority for, any conflicting treatment.

5.1.3 BSCCo on behalf of the BSC Clearer shall ensure that details of each such agreement as is referred to in this paragraph 5.1 are provided to each Payment Party upon its becoming a Party and upon any change in such agreement.

5.2 Withholdings on account of taxation

5.2.1 The FAA on behalf of the BSC Clearer and any BSC Debtor shall deduct from all payments made by or through it under this Section N any deductions (including withholdings) as are required by law and any such agreement as is referred to in paragraph 5.1.

5.2.2 Such deduction shall be the minimum amount required by law and any such agreement as is referred to in paragraph 5.1.

5.2.3 If any such deductions are made, the FAA on behalf of the BSC Clearer or the relevant BSC Debtor (as the case may be) shall take such further actions as are required by law and any such agreement as is referred to in paragraph 5.1, including making payments and returns to the tax authorities and promptly issuing certificates.

5.3 Taxation of BSC Clearer

5.3.1 Subject to this paragraph 5, if at any time and for any reason the BSC Clearer has an obligation to account for any taxation to any taxation authority, where it has no equivalent credit then available to it but the FAA reasonably believes that such a credit will be receivable from such taxation authority in the future, the FAA on behalf of the BSC Clearer shall borrow the required amount from BSCCo, and BSCCo shall lend such amount, on such terms (if any) as BSCCo may decide, and the FAA on behalf of the BSC Clearer shall repay that amount upon receipt of the equivalent credit from the taxation authority.

5.4 Value Added Tax

5.4.1 Each Party shall, for the purposes of enabling the BSC Clearer to charge and pay the correct amounts in respect of VAT and of enabling BSCCo to account for the correct amounts of VAT, notify BSCCo in accordance with BSCP301 such information about that Party relating to VAT as BSCCo requests.

5.4.2 Each Party shall notify BSCCo (in accordance with BSCP301) as soon as it has actual knowledge that any information which it has given to BSCCo in accordance with paragraph 5.4.1 may change, will change or has changed.

5.4.3 The BSC Clearer, BSCCo and the Parties shall and shall be entitled to charge amounts in respect of VAT in accordance with any agreement referred to in paragraph 5.1.1, on the following basis, subject to paragraph 5.4.4:

(i) if a Party has not notified BSCCo to the contrary in accordance with paragraphs 5.4.1 or 5.4.2, that the address (the "Relevant VAT Address") of such Party's relevant business or fixed establishment (within the meaning of Part 3 of The Value Added Tax (Place of Supply of Goods) Order 2004 as amended by The Value Added Tax (Miscellaneous Amendments and Revocations) (EU Exit) Regulations 2019is in the United Kingdom;

(ii) if a Party has not notified BSCCo to the contrary in accordance with paragraphs 5.4.1 or 5.4.2, that such Party has not been issued with an individual identification number by the Member State where its Relevant VAT Address is located; and

(iii) if a Party has notified BSCCo in accordance with either paragraphs 5.4.1 and 5.4.2, that the information contained in the latest such notification is correct.

5.4.4 If in a particular case BSCCo and/or the BSC Clearer reasonably believe that any of the assumptions referred to in paragraphs 5.4.3(i), (ii) or (iii) is incorrect, they shall be entitled but not obliged to charge amounts in respect of VAT on the basis of that belief.

5.4.5 If, in relation to a payment made to BSC Clearer or BSCCo by a Party, that payment has not been increased on account of VAT, for reasons including but not limited to that Party's Relevant VAT Address not being located in the United Kingdom or the Isle of Man, that Party shall (by way of increasing that payment but subject to paragraph 5.4.7) indemnify BSCCo and BSC Clearer in respect of:

(a) any VAT (including interest and penalties) which BSCCo or BSC Clearer becomes liable to pay; and

(b) any reduction in the amount of VAT which BSCCo or BSC Clearer is entitled to recover;

arising because that payment constituted the consideration for a taxable or deemed taxable supply (as such terms are used in the Value Added Tax Act 1994 ("VATA 1994")).

5.4.6 If, in relation to a payment made to a Party by BSC Clearer or BSCCo, that payment has been increased on account of VAT, for reasons including but not limited to that Party's Relevant VAT Address being located in the United Kingdom or the Isle of Man, that Party shall (subject to paragraph 5.4.7) indemnify BSCCo to the extent that BSCCo and BSC Clearer are not entitled to a credit for input tax for the increased part of that payment because that payment did not constitute the consideration for a taxable or deemed taxable supply (as such terms are used in VATA 1994).

5.4.7 Paragraphs 5.4.5 and 5.4.6 shall not apply to the extent that BSC Clearer or BSCCo has been compensated by, in the case of paragraph 5.4.5, an increase to the relevant payment, or, in the case of paragraph 5.4.6, a rebate of the relevant payment.

5.4.8 Any part of the Code providing that an amount that is payable should be increased by an amount in respect of VAT, or should otherwise be paid with an amount attributable to VAT or in respect of VAT, shall not apply to amounts constituting consideration for a taxable or deemed taxable supply (as such terms are used in VATA 1994) where the VAT is payable by the recipient of that supply (or any person that is treated as the recipient in accordance with any agreement referred to in paragraph 5.1.1) by way of the reverse charge mechanism.

5.4.9 The FAA shall retain and, on request, grant BSCCo access to the following documents for such period as may be required by law:

(a) sufficient information to allow it to comply with its obligations under applicable VAT legislation; and

(b) copies of all VAT invoices (or other documents that H.M. Customs & Excise have agreed to treat as VAT invoices) for taxable or deemed taxable supplies (as such terms are used in VATA 1994) made to BSCCo.

6. CALCULATION OF PAYMENTS

6.1 Settlement Runs

6.1.1 In relation to each Settlement Day, following each Settlement Run, the information referred to in paragraphs 6.1.2 to 6.1.4 (inclusive) concerning Trading Charges in respect of Settlement Periods in that Settlement Day is to be submitted in accordance with any timings specified in BSCP301 on the relevant Notification Date by the SAA to the FAA.

6.1.2 The following information is to be submitted in relation to each Settlement Run:

(a) the Settlement Day; and

(b) whether the Settlement Run is an Initial Settlement Run, Timetabled Reconciliation Settlement Run or Post-Final Settlement Run.

6.1.3 The following information (subject to paragraph 6.1.5) is to be submitted for each Imbalance Party:

(a) the identity of the Imbalance Party;

(b) the amount (exclusive of VAT) calculated for the Settlement Day in respect of each of the following Trading Charges separately:

(i) the Daily Party BM Unit Cashflow;

(ii) the Daily Party Non-Delivery Charge;

(iii) the Daily Party Energy Imbalance Cashflow;

(iv) the Daily Party Information Imbalance Charges;

(v) the Daily Party Residual Settlement Cashflow;

(vi) the Daily Party RR Instruction Deviation Cashflow;

(vii) the Daily Party RR Cashflow;

(viii) the Daily Virtual Lead Party Compensation Cashflow; and

(ix) the Daily Supplier Compensation Cashflow.

(c) the net credit or debit amount (exclusive of VAT) for the Settlement Day for all Trading Charges under paragraph (b) for that Imbalance Party.

6.1.4 The following information (subject to paragraph 6.1.5) is to be submitted in relation to the NETSO: the Daily System Operator Cashflow which shall be a single credit or debit amount (exclusive of VAT) for the Settlement Day.

6.1.5 In relation to any Reconciliation Settlement Run, the amounts referred to in paragraphs 6.1.3 and 6.1.4 are to be determined as though it were the first Settlement Run to be carried out in relation to the relevant Settlement Day, and so disregarding any payments which may on any prior Payment Date have been paid or payable in respect of the relevant Settlement Day.

6.1.6 For the purposes of this Section N, in relation to any Settlement Day and Notification Date, the amount (in relation to an Imbalance Party) under paragraph 6.1.3(c) and the amount (in relation to the NETSO) under paragraph 6.1.4 is the "Trading Charges Amount".

6.2 Validation by FAA

6.2.1 Upon receipt of the information supplied by the SAA, the FAA shall determine whether, on the basis of such information:

(a) the aggregate of the debit Trading Charges Amounts (excluding any amounts attributable to VAT) for all Payment Parties for the relevant Settlement Day (the "total debits") is equal to

(b) the aggregate of the credit Trading Charges Amounts (excluding any amounts attributable to VAT) for all Payment Parties for the relevant Settlement Day (the "total credits").

6.2.2 If the difference between the total debits and the total credits is less than the amount stipulated in sterling in accordance with BSCP301 , such information is "valid".

6.2.3 If the information is valid and there is a difference between the total debits and the total credits, the FAA shall account for such difference by adjusting the Daily Party Residual Settlement Cashflow and the Trading Charges Amount for the Imbalance Party with the largest absolute Trading Charges Amount for the relevant Settlement Day by the amount of such difference and references to "Trading Charges Amounts" in paragraphs 6.4, 6.5, and 7 below are to Trading Charges Amounts so adjusted.

6.3 Rectification of errors

6.3.1 If the FAA determines that the information provided by the SAA is not valid in accordance with paragraph 6.2, it shall as soon as possible notify the SAA accordingly, but if the FAA has not so notified the SAA by the close of business on the Notification Date, the SAA may assume that FAA has determined that the information is valid in accordance with paragraph 6.2.

6.3.2 Upon receiving a notice under paragraph 6.3.1, the SAA will use its best endeavours promptly to provide corrected information as may be necessary for the FAA to determine whether the corrected information is valid and to enable it to issue Invoices in accordance with paragraph 7.

6.4 Reconciliation

6.4.1 Upon receipt of the information supplied by the SAA in a Reconciliation Settlement Run, the FAA shall calculate, on the basis of such information, for each Payment Party, the difference (if any) between:

(a) the debit or credit Trading Charges Amount calculated in that Reconciliation Settlement Run for that Payment Party;

and

(b) either:

(i) the debit or credit Trading Charges Amount calculated for that Payment Party in the Initial Settlement Run for the same Settlement Day; or

(ii) (if a Reconciliation Settlement Run has already been carried out in respect of that Settlement Day) the debit or credit Trading Charges Amount calculated for that Payment Party in the most recent Reconciliation Settlement Run previously carried out for that Settlement Day (other than a Reconciliation Settlement Run not used to calculate Reconciliation Charges in accordance with paragraph 6.6.3).

6.4.2 Subject to paragraph 5, each Payment Party shall following each Reconciliation Settlement Run be liable to pay to, or (as the case may be) entitled to receive from, the BSC Clearer an amount calculated as being:

(a) the amount of the difference determined under paragraph 6.4.1; plus

(b) interest, calculated on a compound basis in accordance with paragraph 6.4.2A ("the interest amount") on the amount of such difference.

6.4.2A The interest amount shall be calculated in respect of the period from (and including) the Payment Date relating to the Initial Settlement Run to (but not including) the relevant Reconciliation Payment Date by applying the Base Rate:

(a) as prevailing at 00:00 hours on the relevant day on a daily basis to the amount of such compounded difference up to (but not including) the Invoice Date; and

(b) as prevailing at 00:00 hours on the Invoice Date on a daily basis to the amount of such compounded difference up to (but not including) the relevant Reconciliation Payment Date.

6.4.3 The amount determined, for a Payment Party and Reconciliation Settlement Run, pursuant to paragraph 6.4.2 shall be a "Reconciliation Charge".

6.4.4 It is hereby acknowledged and agreed that the obligations of Payment Parties and the BSC Clearer under paragraphs 2.8.2 (a) and 6.4.2 are new obligations to pay an amount by way of Trading Charge and not an adjustment or amendment of any existing obligation and those obligations are subject to the provisions of paragraphs 2.4 to 2.7 (inclusive).

6.5 Amounts in Invoices

6.5.1 If the information supplied by the SAA is valid, the amounts to be incorporated in Invoices in accordance with paragraph 7.1:

(a) in relation to an Initial Settlement Run, shall be the Trading Charges Amounts; and

(b) in relation to a Reconciliation Settlement Run, shall be the Reconciliation Charges

together with an amount in respect of applicable VAT on the amount payable.

6.6 Postponed Payments

6.6.1 If no information is received by the FAA in respect of a Settlement Run on a Notification Date or for any reason it is not possible, after application of paragraph 6.3, for the FAA to determine by the close of business on the Notification Date the amounts to be incorporated in the Invoices:

(a) the Payment Date shall be postponed so that it falls on the second Business Day (or such later day as the Panel shall from time to time decide upon request of the FAA) after the day on which the FAA receives and/or validates the information provided by the SAA pursuant to paragraph 6.2;

(b) the FAA shall inform the Panel, BSCCo, the SAA and each Payment Party:

(i) upon the Notification Date, of such postponement; and

(ii) promptly upon validating such information, of the postponed Payment Date;

(c) such postponed date shall be a "Postponed Payment Date", and a reference to a Payment Date in this Section N shall, unless the context otherwise requires, include a Postponed Payment Date.

6.6.2 In the case of an Initial Settlement Run only, if the Postponed Payment Date falls more than one week after the original Payment Date:

(a) each BSC Debtor shall pay to the BSC Clearer; and

(b) each BSC Creditor shall receive from the BSC Clearer

(but subject to paragraphs 2.4 to 2.7 (inclusive)) interest calculated on a compound basis in accordance with paragraph 6.6.2A.

6.6.2A For the purposes of paragraph 6.6.2, interest shall be calculated on the amount shown in the Invoice in respect of the period from (and including) the originally scheduled Payment Date to (but not including) the Postponed Payment Date by applying the Base Rate:

(a) as prevailing at 00:00 hours on the relevant day on a daily compounded basis up to (but not including) the Invoice Date for the Postponed Payment Date; and

(b) as prevailing at 00:00 on the Invoice Date for the Postponed Payment Date on a daily compounded basis up to (but not including) the Postponed Payment Date.

6.6.3 In the case of a Timetabled Reconciliation Settlement Run, other than a Final Reconciliation Settlement Run:

(a) the Panel may at any time after receiving a notice under paragraph 6.6.1(b)(i), but not after the FAA has given a notice under paragraph 6.6.1(b)(ii), determine and instruct the FAA that Reconciliation Charges will not be determined and payable by reference to that Reconciliation Settlement Run;

(b) if the Panel makes such a determination:

(i) the FAA shall promptly notify all Payment Parties and the SAA of the Panel’s determination; and

(ii) there shall be no Postponed Settlement Date;

but without prejudice to the determination of Reconciliation Charges by reference to the next following Timetabled Reconciliation Settlement Run for the relevant Settlement Day.

6.6.4 Where in accordance with Section T5.4 BSCCo submits to the FAA data and information estimated by the Panel:

(a) the FAA shall determine the amounts to be incorporated in Invoice on the basis of such data and information (and this paragraph 6 shall apply as though such data and information were information supplied by the SAA under paragraph 6.1);

(b) the Postponed Payment Date shall accordingly be established in accordance with paragraph 6.6.1(a) by reference to the day on which the FAA receives the data estimated by the Panel.

6.7 Payment by BSC Debtors, the BSC Clearer and BSCCo

8.4 Excess payments

8.4.1 If on the Business Day following any Payment Date the FAA receives from a BSC Debtor a payment in excess of the amount notified to that BSC Debtor pursuant to paragraph 7.1 in respect of that Payment Date, or amounts greater than the amounts notified pursuant to paragraph 7.1. 5 have been credited to the Clearing Account, the FAA shall use its reasonable endeavours to ascertain the nature of the excess payment, to calculate the entitlement to such payment and to instruct the BSC Banker that day to credit the relevant BSC Debtor's Settlement Account or (if so requested by the BSC Debtor) the Reserve Account or such other account authorised by BSCCo. The timings of the FAA’s actions pursuant to this paragraph 8.4.1 shall be as stipulated in BSCP301.

8.4.2 Any Payment Party who instructs its bank to make a payment in excess of the amount owing by that Payment Party on any Payment Date shall simultaneously with giving such instructions advise the FAA in writing of the amount of the excess payment providing a description of what that Payment Party considers the excess payment relates to.

(i) the amount (if any) which would be required to be drawn on the Credit Facility in order to enable full payment to be made of the amounts due to BSC Creditors;

(ii) whether, and if so the amount (“possible shortfall amount”) by which, the amount in paragraph (i) exceeds the amount then remaining available to make a Drawing;

8.5.2 Subject to paragraph 8.5.4, as soon as practicable and not later than 16.00 hours on the Payment Date the FAA shall arrange for the remittance from the Clearing Account to the relevant Settlement Accounts maintained by the BSC Creditors of the aggregate of amounts determined by the FAA to be available for payment to BSC Creditors and, if required, arrange for the transfer of amounts from the Reserve Account or (subject to paragraph 8.5.3) the Borrowing Account to the Clearing Account or vice versa.

8.5.3 Subject to paragraph 8.5.4, any differences between the amount of the FAA’s estimate under paragraph 8.5.1(a) and the aggregate amount actually credited to the Collection Account in accordance with paragraph 8.1 on the Payment Date shall be addressed by way of adjustment (later on the Payment Date) to the amount of any Drawing, and the FAA shall arrange for such adjustment to be made in respect of the transfer of any amount from the Borrowing Account to the Clearing Account or vice versa.

8.6 Prohibition on transfers

8.6.1 The FAA shall not at any time instruct the BSC Banker to transfer any sum from a BSC Account to another account (not being a BSC Account) unless that account is a Settlement Account or (in the case of erroneous payments to the BSC Clearer) with the authority of BSCCo and the relevant Payment Party concerned.

8.6.2 Notwithstanding paragraph 8.6.1, the FAA may instruct the BSC Banker to transfer monies between the Reserve Account and an Investment Account.

(a) an "Amount in Default" is all or any part of any amount due and payable from a BSC Debtor to the BSC Clearer which is not remitted to the Collection Account by 23.59 hours on the relevant Payment Date and, at any time thereafter, together with interest payable by that Non-paying BSC Debtor pursuant to paragraph 9.4 and less any amounts paid or recovered (as defined in paragraph 9.3.1) in respect thereof at that time;

(b) a "Drawing" is a drawing on the Credit Facility by the FAA on behalf of the BSC Clearer and includes interest and banking charges charged to the BSC Clearer by the BSC Banker from time to time;

(d) the "VAT Element" means, in respect of any payment, part of that payment equal to the VAT that is chargeable on the taxable supply or deemed taxable supply for which the payment constitutes the consideration; and

(e) the "VAT Exclusive Element" means, in respect of any payment, part of that payment equal to that payment less the VAT Element of that payment.

9.2 Affected Date

9.2.1 Paragraph 9.2.2 shall apply if, on any Payment Date (such date, in respect of the Settlement Day to which it relates, the "Affected Date"), the FAA has been notified by a Settlement Bank or it otherwise has reason to believe there will be an Amount in Default in respect of any BSC Debtor (the "Non-paying BSC Debtor").

9.2.2 Where this paragraph 9.2.2 applies, subject to paragraphs 8.5.4 and 9.2.5, the FAA shall, on behalf of the BSC Clearer, act in accordance with the following provisions (or whichever of them shall apply) in the order in which they appear, until the FAA is satisfied that the Clearing Account will clear to zero not later than the close of business on the Affected Date:

(a) if a Credit Facility is available to the BSC Clearer, the FAA shall make a Drawing by debiting the Borrowing Account and crediting the Clearing Account with a sum being the lesser of the Amount in Default and the amount available for drawing under the Credit Facility;

(b) if the FAA is satisfied that any Cash Cover provided by the Non-paying BSC Debtor will be paid into the Clearing Account in sufficient time to ensure that that Cash Cover can be applied to the Amount in Default by close of business on the Affected Date, the FAA shall debit the Reserve Account and credit the Clearing Account with a sum being the lesser of the Amount in Default (to the extent that it will not be covered by the amount borrowed by application of paragraph (a)) and that Cash Cover;

(c) if the FAA is satisfied that the proceeds of a call under the Letter(s) of Credit supplied by the Non-paying BSC Debtor will be paid into the Clearing Account in sufficient time to ensure that those proceeds can be applied to the Amount in Default by close of business on the Affected Date, the FAA shall make a call under the Letter of Credit(s) in a sum not exceeding the lesser of the Amount in Default (to the extent it will not be covered by the application of paragraph (a) or recovered by the application of paragraph (b)) and the available amount of such Letter(s) of Credit and the FAA shall cause the proceeds of such call to be paid into the Clearing Account; and

(d) if and to the extent that, notwithstanding application of the foregoing measures, it is not possible to credit an amount in cleared funds equal to the Amount in Default to the Clearing Account by close of business on the Affected Date, the FAA shall:

(i) on behalf of the BSC Clearer, reduce the VAT Exclusive Elements of the payments by the BSC Clearer to all BSC Creditors in proportion to the VAT Exclusive Element of the amounts payable to them by the BSC Clearer on and in respect of the Affected Date by an aggregate amount equal to the amount necessary to cover the VAT Exclusive Element of the Amount in Default (to the extent it will not be covered by the application of paragraph (a) or recovered by the application of paragraphs (b) or (c));

(ii) determine and pay the appropriate VAT Elements (if any) of the payments by the BSC Clearer to all BSC Creditors accordingly; and

(iii) (subject to paragraph 2.7) account for such reduction in the Ledger Accounts as amounts due and owing by the BSC Clearer to each BSC Creditor (a "Shortfall Creditor") whose payments were so reduced; and

(e) notify BSCCo and (in the case of action under paragraph (b) or (c)) the Non-paying BSC Debtor as soon as reasonably practicable of the action taken.

9.2.3 For the purposes of this paragraph 9, the amount of the reduction pursuant to paragraph 9.2.2(d) plus interest at the Default Interest Rate from time to time in respect of each Shortfall Creditor is a "Shortfall Amount".

9.2.4 It is acknowledged for the avoidance of doubt that the FAA may (for the purposes of paragraph 9.2.1) have reason to believe, before a given Payment Date, that there will on that Payment Date be an Amount in Default in respect of a BSC Debtor; and in such case the FAA may (if it is feasible to do so) take steps before such date to implement paragraph 9.2.2(b) or (c) on that date.

9.2.5 Where there is an Amount in Default on a Payment Date in respect of a BSC Debtor which is a Defaulting Party, the order in which the FAA shall act in accordance with the provisions (or whichever of them shall apply) of the sub-paragraphs of paragraph 9.2.2 shall be as follows: (b), (c), (a), (d) (and references therein to the application of prior paragraphs shall be construed accordingly).

9.3 Amount in Default

9.3.1 For the purposes of this Section N, an Amount in Default shall be "paid or recovered" on any Business Day, only if, and to the extent that:

(a) an amount has been paid to the BSC Clearer on that Business Day and applied by the FAA on behalf of the BSC Clearer to that Amount in Default; or

(b) it has been recovered from the Non-paying BSC Debtor on that Business Day by operation of set-off pursuant to paragraph 2.6; or

(c) it has been recovered from the Non-paying BSC Debtor on that Business Day by applying its Cash Cover or the proceeds of its Letter of Credit in accordance with this paragraph 9.

9.3.2 Any amount received from a Non-paying BSC Debtor shall be applied by the FAA on behalf of the BSC Clearer in or towards Amounts in Default payable by the Non-paying BSC Debtor to the BSC Clearer on each successive Payment Date in respect of which there is an outstanding default, with the longest outstanding default being settled first, and where a day is a Payment Date for more than one Settlement Day, with the default in respect of the earliest Settlement Day being settled first.

9.3.3 As soon as any portion of an Amount in Default (whether attributable to principal or interest) is paid or recovered, the FAA on behalf of the BSC Clearer shall:

(a) first, apply the proceeds to the Drawing;

(b) secondly, apply the VAT Exclusive Element of any remaining proceeds to (and in proportion to) the VAT Exclusive Elements of the Shortfall Amounts or the Default Share Amounts (in accordance with paragraph 9.6.8 below) in relation to that Amount in Default; and

(c) determine and pay the amount of VAT (if any) attributable to amounts paid pursuant to paragraph 9.3.3(b) accordingly.

9.3.4 Consistent with paragraph 9.3.3, for the purposes of determining amounts payable pursuant to paragraphs 9.5.2 and 9.5.3, references in those paragraphs to certain amounts shall be construed as follows:

(a) in the context of the payment or recovery of all or part of an Amount in Default from a Non-paying BSC Debtor (including payment or recovery by debiting the Reserve Account or making a call under a Letter of Credit), such references are to both the VAT Element and the VAT Exclusive Element of that amount;

(b) in the context of the application of an amount so paid or recovered (including application by way of crediting the Borrowing Account, or payment to Shortfall Creditors):

(i) such references are to the VAT Exclusive Element of that amount;

(ii) the amount of VAT (if any) attributable to amounts so applied shall be separately determined.

9.4 Interest

9.4.1 Each Non-paying BSC Debtor shall pay to the account of the BSC Clearer interest from time to time (after as well as before judgment) calculated on a compound basis by applying the prevailing Default Interest Rate on a daily basis to the part of the Amount in Default (as compounded) not covered by a Drawing from the due date up to (but not including) the day of its payment or recovery from the Non-paying Debtor.

(a) debit the Reserve Account with a sum being the lesser of the Amount in Default (including interest at the Default Interest Rate) and that Non-paying BSC Debtor’s Cash Cover and credit the Settlement Accounts (and the ledger accounts) of the Shortfall Creditors with that sum, in proportion to their respective Shortfall Amounts; and

(b) if, after the application of paragraph (a), there remains any Shortfall Amounts:

(i) make a call under the Non-paying BSC Debtor’s Letter of Credit in a sum not exceeding the lesser of the Amount in Default (including interest due pursuant to paragraph 9.4) and the available amount of such Letter(s) of Credit; and

(ii) cause the proceeds of such call to be paid forthwith into the Reserve Account.

9.5.3 On the next Business Day following receipt of such proceeds under a Letter of Credit in accordance with paragraph 9.5.2 (b), the FAA shall pay on behalf of the BSC Clearer such amounts as have been credited to the Reserve Account to the Shortfall Creditors in full or (as the case may be) in proportion to their respective Shortfall Amounts, except where paragraph 9.6.8 applies.

(a) the Non-paying BSC Debtor has provided Cash Cover but for any reason the Reserve Account has not yet been debited in accordance with paragraph 9.5.2(a) or 9.6.2(a), and/or

(b) the Non-paying BSC Debtor has provided Letter(s) of Credit, the FAA has (in accordance with paragraph 9.5.2(b) or 9.6.2(b)) made call(s) thereon which have not yet been paid, but the FAA has no reason to believe such call(s) will not be paid; and

(c) the sum of the available amount of such Cash Cover and/or (otherwise uncalled) amounts of such Letter(s) of Credit subject to such call is sufficient to enable the outstanding Amount in Default to be paid or recovered,

the FAA, with the approval of BSCCo, may defer acting in accordance with paragraph 9.6.4 for a period not exceeding three Business Days; and accordingly where this paragraph 9.6.3A applies the reference in paragraph 9.6.3 to D+2 shall be a reference to such later day as the FAA shall determine, not being later than five Business Days after the Affected Date.

9.6.3B Where:

(a) the Non-paying BSC Debtor has received an Invoice in respect of a Notification Date which is also a Quarter Date pursuant to paragraph 7.1.5(b); and

(b) the aggregate amount payable in respect of that Invoice is less than the Invoice Threshold Limit,

the FAA, with approval of BSCCo, may defer acting in accordance with paragraph 9.6.4 for a period not exceeding thirteen Business Days; and accordingly where this paragraph 9.6.3B applies the reference in paragraph 9.6.3 to D+2 shall be a reference to such later day as the FAA shall determine, not being later than fifteen Business Days after the Affected Date.

9.6.4 Where this paragraph 9.6.4 applies, the FAA shall:

(a) determine the VAT Exclusive Element of the Amount in Default (including all interest accrued thereon) which has not been paid or recovered;

(b) determine for each Payment Party other than Virtual Lead Parties and the Non-paying BSC Debtor the amount (the "Default Share Amount") of that Payment Party’s Annual Funding Share (on a default basis, for the month in which the Affected Date fell) of that VAT Exclusive Element of the Amount in Default;

(c) in good time (in accordance with BSCP301) for the relevant Payment Parties to give instructions for payments to be effected on the Default Payment Date, despatch to BSCCo and each Payment Party other than the Non-paying BSC Debtor an Invoice showing the amount or amounts (as applicable to that Payment Party) determined under paragraph 9.6.5 below increased to take VAT into account; and

(d) notify BSCCo, the Panel and each Payment Party.

9.6.5 The amounts are:

(a) for each Payment Party, the Default Share Amount; and

(b) for each Shortfall Creditor:

(i) the VAT Exclusive Element of the outstanding Shortfall Amount (including interest applied at the Default Interest Rate for each day on a compounded basis from and including the Affected Date to, but excluding, the Default Payment Date (as defined below)); and

(ii) the difference between the amounts under paragraph (a) and paragraph (b)(i).

9.6.6 Each Payment Party shall be liable to pay or (where the amount under paragraph 9.6.5(b)(i) is greater than the amount under paragraph 9.6.5(a)) entitled to receive the amount set out in the relevant Invoice calculated in accordance with paragraph 9.6.5 (a) or if applicable, paragraph 9.6.5(b)(ii), on the second Business Day (the "Default Payment Date") after the date of the Invoice and any payment made by a Payment Party to the BSC Clearer in accordance with this paragraph is a limited recourse loan on which interest is payable and which is repayable only to the extent set out in paragraph 9.6.8.

9.6.7 The provisions of paragraphs 8 and 9 shall apply to the making of payments under paragraph 9.6.6 and Payment Parties who fail to pay the amount in the Invoice by the Default Payment Date shall be Non-paying BSC Debtors.

9.6.8 If, after despatching Invoices under paragraph 9.6.4(c):

(a) any portion of the Amount in Default attributable to principal is paid or recovered, the FAA on behalf of the BSC Clearer shall distribute the VAT Exclusive Element (increased by an amount in respect of VAT if applicable) of such amounts to Payment Parties in their Annual Funding Shares (as referred to in paragraph 9.6.4(b)); or

(b) any portion of the Amount in Default attributable to interest is paid or recovered, the FAA on behalf of the BSC Clearer shall distribute such amounts to Payment Parties in their Annual Funding Shares (as referred to in paragraph 9.6.4(b)).

9.6.9 To the extent that the VAT Element of amounts received by the BSC Clearer (net of the VAT Element of amounts paid by the BSC Clearer) in respect of an Amount in Default under paragraph 9.6.6 are insufficient to repay that part of the Drawing (if any) representing the part of that Amount of Default that is attributable to VAT, BSCCo shall pay an amount equal to the excess into the Credit Facility.

9.6.10 Notwithstanding anything to the contrary herein, this paragraph shall apply if, on any Notification Date:

(a) any BSC Debtor is a Defaulting Party; and

(b) the FAA is reasonably satisfied that:

(i) the Credit Cover provided by that Defaulting Party will be insufficient to settle the Amount in Default (including interest due on that sum) of that Defaulting Party; and

(ii) there is no prospect of the Defaulting Party being in a position to settle any Amount in Default (including interest due on that sum) by the Payment Date

then, the FAA may, with the approval of BSCCo, on the basis that it is in the best interests of all BSC Parties not to incur Credit Facility interest in relation to the Amount in Default, immediately apply section 9.6.4 without needing to consider or follow the normal process set out in 9.5 , 9.6.1, 9.6.2, 9.6.2A and 9.6.3.

9.7 No liability

9.7.1 The BSC Clearer shall have no liability in respect of any Shortfall Amount or Default Share Amount in accordance with this paragraph 9, save to the extent that the Amount in Default (including interest) is paid or recovered.

SECTION P: ENERGY CONTRACT VOLUMES AND METERED VOLUME REALLOCATIONS

1. GENERAL

1.1 Introduction

1.1.1 This Section P sets out:

(a) the basis on which persons may be authorised by Contract Trading Parties to notify Energy Contract Volume Data and Metered Volume Reallocation Data:

(b) the basis on which Energy Contract Volume Data and Metered Volume Reallocation Data:

(i) may be notified on behalf of Contract Trading Parties and validated;

(ii) not used;

(iii) may be treated as refused or rejected in certain cases of Credit Default; and

(iv) will be aggregated in order to be taken into account in Settlement.

1.2 Authorisations - general

1.2.1 Energy Contract Volume Data and Metered Volume Reallocation Data may only be notified by an Energy Contract Volume Notification Agent and a Metered Volume Reallocation Notification Agent respectively in accordance with the provisions of this Section P and Section J.

1.2.2 A Contract Trading Party:

(a) shall not include in any ECVNA Authorisation or MVRNA Authorisation any qualification of or condition as to the authority of the relevant Energy Contract Volume Notification Agent or Metered Volume Reallocation Notification Agent, other than:

(i) the effective period; and

(ii) in the case of an ECVNA Authorisation submitted after the Relevant Implementation Date of Modification Proposal P309, an authorisation to submit only Replacement Energy Contract Volume Notifications or only Additional Energy Contract Volume Notifications under that ECVNA Authorisation;

(b) shall for the purposes of the Code be bound by, and may not challenge or dispute under or for the purposes of the Code:

(i) any Energy Contract Volume Notification or Metered Volume Reallocation Notification submitted by any Energy Contract Volume Notification Agent or Metered Volume Reallocation Notification Agent; and

(ii) any omission or failure to submit any Energy Contract Volume Notification or Metered Volume Reallocation Notification by any Energy Contract Volume Notification Agent or Metered Volume Reallocation Notification Agent

which has been authorised by that Contract Trading Party and whose authorisation remains effective at the relevant time in accordance with this Section P.

1.2.3 An ECVNA Authorisation or MVRNA Authorisation authorises the submission, while it is effective, of Energy Contract Volume Notifications or (as the case may be) Metered Volume Reallocation Notifications, irrespective of the period for which any such notification is to be in force; and accordingly such a notification will be and remain in force notwithstanding that the corresponding authorisation may cease to be effective.

1.2.4 Energy Contract Volume Notifications and Metered Volume Reallocation Notifications shall not be in force with respect to any Settlement Period for which, the Submission Deadline is before the time at which such notification is received (in accordance with Section O) by the Energy Contract Volume Aggregation Agent but subject to paragraphs 2.3.10, 3.3.10 and 5.

1.2.5 In respect of Clock Change Days for which Energy Contract Volume Notifications or Metered Volume Reallocation Notifications are submitted which do not take account of the Clock Change, the Energy Contract Volume Aggregation Agent will apply defaulting rules such as to ignore values submitted in respect of the third and fourth Settlement Periods of that Settlement Day (for a short Clock Change Day) and to repeat values submitted in respect of the third and fourth Settlement Periods of that Settlement Day (for a long Clock Change Day), or such other or supplementary defaulting rules as may be approved from time to time by the Panel and notified by BSCCo to Trading Parties and the NETSO.

1.3 Further provisions

1.3.1 An ECVNA Authorisation or MVRNA Authorisation shall be effective for the period commencing on the later of:

(a) the effective date specified in such authorisation, and

(b) the day following that on which the ECVAA gives notice of confirmation thereof pursuant to this Section P;

and ending on the last day, if specified, of its effectiveness, or otherwise continuing until such authorisation is terminated.

1.3.2 Unless it is not valid (pursuant to paragraph 2.3.4 or 3.3.4) or treated as refused (pursuant to paragraph 2.5.1 or 3.5.1), an Energy Contract Volume Notification or Metered Volume Reallocation Notification shall be in force (subject to paragraphs 1.2.4, 2.5.2 and 3.5.2) in respect of each Settlement Day within the period commencing on its Effective-from Date and ending on its Effective-to Date (if any) or otherwise continuing until and unless replaced pursuant to paragraph 2.3.5(a) or 3.3.5(a).

1.3.3 For the avoidance of doubt, the information that an Energy Contract Volume Notification or Metered Volume Reallocation Notification is not valid or is (pursuant to paragraph 2.5.1 or 3.5.1) treated as refused, may be given to the Relevant Contract Parties (pursuant to Section V) after its Effective-from Date but without prejudice to paragraphs 2.3.10 and 3.3.10.

1.3.4 Energy Contract Volume Data may have a positive or a negative value.

1.3.5 In relation to any ECVNA Authorisation or Energy Contract Volume Notification:

(a) subject to paragraph 1.4, the "Relevant Contract Parties" are the two Contract Trading Parties by whom the two Energy Contract Volume Notification Agents are to be appointed or (as the case may be) on whose behalf Energy Contract Volumes are notified;

(b) the "Energy (To) Account" is the Energy Account (of one Relevant Contract Party) to which Energy Contract Volume(s) are to be credited or from which Energy Contract Volume(s) are to be nullified;

(c) the "Energy (From) Account" is the Energy Account (of the other Relevant Contract Party) from which Energy Contract Volume(s) are to be debited or from which Energy Contract Volume(s) are to be nullified;

and accordingly where the Energy Contract Volume Data is positive an Energy Contract Volume Notification has the effect of transferring the relevant Energy Contract Volume from the Energy (From) Account of one Relevant Contract Party to the Energy (To) Account of the other Relevant Contract Party.

1.4 Single Relevant Contract Party

1.4.1 An ECVNA Authorisation and Energy Contract Volume Notifications may be submitted on behalf of a single Trading Party in the capacity of both Relevant Contract Parties, who may (by such a notification) transfer Energy Contract Volume(s) from one of its Energy Accounts to the other.

1.4.2 Any provisions of the Code which refer to both, or two, Relevant Contract Parties, or to either Relevant Contract Party, or which otherwise imply that there must be two Relevant Contract Parties, shall be construed so as to give effect to this paragraph 1.4.

1.5 Single Energy Contract Notification Agent or Single Metered Volume Reallocation Notification Agent

1.5.1 Where the same person is appointed as an Energy Contract Volume Notification Agent by each of the Relevant Contract Parties by an ECVNA Authorisation, the Energy Contract Volume Notification Agent so appointed shall submit Energy Contract Volume Notifications on behalf of each of the Relevant Contract Parties.

1.5.2 Where the same person is appointed as a Metered Volume Reallocation Notification Agent by each of the Lead Party and the Subsidiary Party by an MVRNA Authorisation, the Metered Volume Reallocation Notification Agent so appointed shall submit Metered Volume Reallocation Notifications on behalf of each of the Lead Party and the Subsidiary Party.

1.5.3 Any provisions of the Code which refer to both, or two, Energy Contract Volume Notification Agents or both, or two, Metered Volume Reallocation Notification Agents, or to either Energy Contract Volume Notification Agent or either Metered Volume Reallocation Notification Agent, or which otherwise imply that there must be two Energy Contract Volume Notification Agents or two Metered Volume Reallocation Notification Agents, shall be construed so as to give effect to this paragraph 1.5.

1.6 Suspension of contract volume notification

1.6.1 Where, for the purposes of any Contingency Provisions, the notification of contract volumes is to be suspended in relation to any Settlement Period:

(a) no Energy Contract Volume Notification shall be taken into account in Settlement as to any Energy Contract Volume Data which relates to that Settlement Period, and accordingly the Account Bilateral Contract Volume shall be zero for all Energy Accounts;

(b) no Metered Volume Reallocation Notification shall be taken into account in Settlement as to any Metered Volume Reallocation Data which relates to that Settlement Period, and accordingly the Metered Volume Fixed Reallocation and the Metered Volume Percentage Reallocation shall be zero for all BM Units and Subsidiary Energy Accounts;

(c) subject to any other provision of the Code relating to Level 2 Credit Default, when (in accordance with the relevant Contingency Provisions) the notification of contract volumes ceases to be suspended, the provisions of this Section P shall apply by reference to all Volume Notifications then in force.

2. ENERGY CONTRACT VOLUMES

then the further ECVNA Authorisation shall, upon and with effect from its becoming effective, replace the first ECVNA Authorisation which shall then cease to be effective.

2.2.4 Where at any time an ECVNA Authorisation ceases to be effective, the Energy Contract Volume Aggregation Agent shall issue a notification to that effect to the Relevant Contract Parties and the Energy Contract Volume Notification Agents in accordance with BSCP71.

2.2.5 Where an ECVNA Authorisation (the "successor" such authorisation) is submitted which:

(a) satisfies the requirements in paragraph 2.2.3(b), except that it specifies a different Energy Contract Volume Notification Agent for either of the Relevant Contract Parties from that for the first authorisation (referred to in paragraph 2.2.3(a)), and

(b) states that it is to replace the first authorisation.

then the successor ECVNA Authorisation shall, upon and with effect from its becoming effective, replace the first ECVNA Authorisation which shall then cease to be effective, and the Energy Contract Volume Notification Agents under the successor ECVNA Authorisation shall be considered to be the same as that under the first for the purposes of paragraph 2.3.5.

2.3 Energy Contract Volume Notifications

2.3.1 Energy Contract Volume Data may be notified by way of an Energy Contract Volume Notification submitted by an Energy Contract Volume Notification Agent.

2.3.1A An Energy Contract Volume Notification shall be one or more of the following types:

(a) an Additional Energy Contract Volume Notification;

(b) an Initial Energy Contract Volume Notification;

2.3.2 An Energy Contract Volume Notification:

(a) shall specify:

(i) the ECVNA Authorisation under which it is given (thereby identifying the Energy (From) Account and the Energy (To) Account),

(ii) the Energy Contract Volume Notification Agent,

(iii) the first Settlement Day on which it is intended to be in force (the "Effective-from Date"), and

(iv) for each Settlement Period, a quantity of Active Energy (expressed in MWh);

(b) shall be submitted in accordance with and subject to BSCP71; and

(i) subject to paragraph 2.3.4(d)(i), that it is to replace, in accordance with paragraph 2.3.5(a), a previous Energy Contract Volume Notification identified (by the ECVN identifier provided for in BSCP71) in such notification; and/or

(ii) the last Settlement Day on which it is to be in force (the "Effective-to Date"), failing which it is to be in force until and unless replaced in accordance with paragraph 2.3.5(a).

2.3.3 Where an Energy Contract Volume Notification is to be in force for more than one Settlement Day, the Energy Contract Volume Data for a given Settlement Period (considered as a period in any day) shall be the same for that period in each Settlement Day for which it is in force.

2.3.4 An Energy Contract Volume Notification shall be valid (but without prejudice to paragraph 1.2.4) if and only if it is made in accordance with BSCP71 and:

(a) there is an effective ECVNA Authorisation with respect to the Energy (From) Account, Energy (To) Account, and the Energy Contract Volume Notification Agent submitting the Energy Contract Volume Notification;

(b) the Energy Contract Volume Notification is submitted within the period of effectiveness of such ECVNA Authorisation;

(c) the Energy Contract Volume for each Settlement Period is a number in MWh, positive or negative, with no more than three digits after the decimal point, and between –99,999.999 and 99,999.999; provided that (subject to paragraph 1.2.5) where in relation to a Settlement Period no value for Energy Contract Volume is specified, a value of zero shall be deemed to be specified; and

(d) where the Energy Contract Volume Notification:

(i) is a Replacement Energy Contract Volume Notification, the relevant ECVNA Authorisation authorises the Energy Contract Volume Notification Agent to submit Replacement Energy Contract Volume Notifications;

(ii) is an Additional Energy Contract Volume Notification, the relevant ECVNA Authorisation authorises the Energy Contract Volume Notification Agent to submit Additional Energy Contract Volume Notifications.

2.3.4A For the purpose of paragraph 2.3.4(d):

(a) the references to an ECVNA Authorisation shall include any change to such authorisation pursuant to an effective Authorisation Change; and

(b) an ECVNA Authorisation validated prior to the Implementation Date of Modification Proposal P309 shall be deemed to authorise an Energy Contract Volume Notification Agent to submit Replacement Energy Contract Volume Notifications or Additional Energy Contract Volume Notifications except to the extent that the Relevant Contract Parties have changed the authority of the Energy Contract Volume Notification Agent in accordance with an Authorisation Change.

2.3.4B For the avoidance of doubt, any authorisation to submit:

(a) only Replacement Energy Contract Volume Notifications; or

(b) only Additional Energy Contract Volume Notifications; or

as specified in an ECVNA Authorisation, shall not affect the ability to submit, or validity of, an Initial Energy Contract Volume Notification and paragraph 2.3.4(d) shall not apply to such notification.

2.3.5 Where a valid (in accordance with paragraph 2.3.4):

(a) Replacement Energy Contract Volume Notification is submitted then, with effect from the Effective-from Date of the Replacement Energy Contract Volume Notification (or, if later, the first Settlement Period from which it is in force pursuant to paragraph 1.2.4), the Replacement Energy Contract Volume Notification shall replace the earlier valid Energy Contract Volume Notification and, the earlier valid Energy Contract Volume Notification shall cease to be in force (or if it is not yet in force, shall not come into force), irrespective of whether the Effective-from Date of the earlier valid Energy Contract Volume Notification falls before or after the Effective-to Date of the Replacement Energy Contract Volume Notification;

(b) Additional Energy Contract Volume Notification is submitted, the Additional Energy Contract Volume Notification shall be additional to the earlier valid Energy Contract Volume Notification, and the earlier valid Energy Contract Volume Notification shall (subject to any other provision of this Section P) remain in (or, as the case may be, come into) force.

(b) determine whether such Energy Contract Volume Notification is to be treated as refused in accordance with paragraph 2.5.1.

2.3.8 Subject to paragraph 2.3.11, the ECVAA will inform the Relevant Contract Parties and the relevant Energy Contract Volume Notification Agent if it does not validate an Energy Contract Volume Notification submitted to it pursuant to this paragraph 2.3.

2.3.9 If:

(a) an Energy Contract Volume Notification Agent submits an Energy Contract Volume Notification (the "original" such notification) which is not valid as provided in paragraph 2.3.4, and

(b) the ECVAA does not so inform the relevant Energy Contract Volume Notification Agent pursuant to paragraph 2.3.8 within 20 minutes after the Energy Contract Volume Notification was received,

then (subject to paragraph 2.3.11) paragraph 2.3.10 shall apply.

2.3.10 In the circumstances in paragraph 2.3.9:

(a) the Energy Contract Volume Notification may be:

(i) amended but only so as to correct those matters which gave rise to the invalidity as provided in paragraph 2.3.4, and

(ii) resubmitted (as so amended) by that Energy Contract Volume Notification Agent at any time not later than the end of the Business Day next following:

(1) the day on which the ECVAA did inform the Energy Contract Volume Notification Agent pursuant to paragraph 2.3.8, or

(2) in the absence of the ECVAA so informing the Energy Contract Volume Notification Agent, Gate Closure for the first Settlement Period for which the Energy Contract Volume Notification would (if valid, and in accordance with paragraph 1.2.4 where applicable) have been taken into account in Settlement; and

(b) the resubmitted Energy Contract Volume Notification:

(i) shall be deemed (for the purposes of the Code) to have been received at the time at which the original such notification was received; and

(ii) if valid in accordance with paragraph 2.3.4, shall, notwithstanding it may be submitted after Gate Closure for any such Settlement Period, be in force and (subject to paragraph 2.5) effective for the Settlement Periods for which the original Energy Contract Volume Notification would (consistent with paragraph 1.2.4) have been in force.

2.3.11 To the extent that a Relevant Contract Party or Energy Contract Volume Notification Agent has requested the ECVAA not to give the information in paragraph 2.3.8, paragraphs 2.3.8, 2.3.9 and 2.3.10 shall not apply in relation to that Party or Agent.

2.4 Not used

2.5 Refusal and rejection for credit reasons

2.5.1 Where either of the Relevant Contract Parties is in Level 2 Credit Default in accordance with Section M3, a relevant Energy Contract Volume Notification which is submitted during the Credit Default Refusal Period will be treated as refused and will not become effective.

2.5.2 Where:

(a) a relevant Energy Contract Volume Notification is in force; and

(b) either of the Relevant Contract Parties is in Level 2 Credit Default in accordance with Section M3.

such Energy Contract Volume Notification will be treated as rejected, and will have no effect, as to Energy Contract Volume Data which relate to relevant Settlement Period(s) (as defined in paragraph 2.5.3) for which Gate Closure falls within the Credit Default Rejection Period.

2.5.3 For the purposes of this paragraph 2.5, a relevant Energy Contract Volume Notification is one which, if in force and not treated as rejected in relation to a Settlement Period (a "relevant" Settlement Period) would have the effect in relation to that Settlement Period of increasing the Energy Indebtedness (in accordance with Section M1.2) of the Party in Level 2 Credit Default.

2.6 Energy Contract Volume

2.6.1 For each Settlement Day or (pursuant to paragraph 1.2.4 or 2.5.2) part thereof for which an Energy Contract Volume Notification is in force and not treated as rejected pursuant to paragraph 2.5.2, for each matched Settlement Period specified in that Energy Contract Volume Notification, the Energy Contract Volume ECQ_zabj shall be the Energy Contract Volume Data specified (for that matched Settlement Period) in the Energy Contract Volume Notification.

2.6.2 Wherever the term ECQ_zabj (or the term 'ECQ' with first and fourth subscripts 'z' and 'j' and second and third subscripts representing Energy Accounts) is used in the Code, the second subscript represents the Energy (From) Account and the third subscript represents the Energy (To) Account, so that (in this example) the term ECQ_zabj means an Energy Contract Volume pursuant to an Energy Contract Volume Notification for which Energy Account 'a' is the Energy (From) Account and Energy Account 'b' is the Energy (To) Account.

3. METERED VOLUME REALLOCATIONS

3.1 Submission of MVRNA Authorisation

3.1.1 Metered Volume Reallocation Notification Agents may be appointed by a MVRNA Authorisation, given by the Lead Party (for the BM Unit to which it relates) and the Subsidiary Party by whom such persons are to be appointed, and submitted to the Energy Contract Volume Aggregation Agent.

then the further MVRNA Authorisation shall, upon and with effect from its becoming effective, replace the first MVRNA Authorisation which shall then cease to be effective.

3.2.4 Where at any time a MVRNA Authorisation ceases to be effective, the Energy Contract Volume Aggregation Agent shall issue a notification to that effect to the Lead Party, Subsidiary Party and Metered Volume Reallocation Notification Agents in accordance with BSCP71.

3.2.5 Where an MVRNA Authorisation (the "successor" such authorisation) is submitted which:

(a) satisfies the requirements in paragraph 3.2.3(b), except that it specifies a different Metered Volume Reallocation Notification Agent for either the Lead Party or the Subsidiary Party from that for the first authorisation (referred to in paragraph 3.2.3(a)), and

(b) states that it is to replace the first authorisation

then the successor MVRNA Authorisation shall, upon and with effect from its becoming effective, replace the first MVRNA Authorisation which shall then cease to be effective, and the Metered Volume Reallocation Notification Agents under the successor MVRNA Authorisation shall be considered to be the same as that under the first for the purposes of paragraph 3.3.5.

3.3 Metered Volume Reallocation Notifications

3.3.1 Metered Volume Reallocation Data may be notified by way of a Metered Volume Reallocation Notification submitted by a Metered Volume Reallocation Notification Agent.

3.3.2 A Metered Volume Reallocation Notification:

(a) shall specify:

(i) the MVRNA Authorisation under which it is given (thereby identifying the BM Unit, the Lead and Subsidiary Parties, and the Subsidiary Energy Account to which it relates);

(ii) the Metered Volume Reallocation Notification Agent,

(iii) the first Settlement Day on which it is intended to be in force (the "Effective-from Date"), and

(iv) for each Settlement Period, a quantity of Active Energy and a percentage (either of which may be zero) in accordance with paragraph 3.6.1;

(b) shall be submitted in accordance with and subject to BSCP71; and

(i) that it is to replace, in accordance with paragraph 3.3.5(a), a previous Metered Volume Reallocation Notification identified (by the MVRN identifier provided for in BSCP71) in such notification; and/or

(ii) the last Settlement Day on which it is to be in force (the "Effective-to Date"), failing which it is to be in force until and unless replaced in accordance with paragraph 3.3.5(a).

3.3.3 Where a Metered Volume Reallocation Notification is to be in force for more than one Settlement Day, the Metered Volume Reallocation Data for a given Settlement Period (considered as a period in any day) shall be the same for that period in each Settlement Day for which it is in force.

3.3.4 A Metered Volume Reallocation Notification shall be valid (but without prejudice to paragraph 1.2.4) if and only if it is made in accordance with BSCP71 and:

(a) there is an effective MVRNA Authorisation with respect to the BM Unit, Subsidiary Energy Account, and Metered Volume Reallocation Notification Agent submitting the Metered Volume Reallocation Notification;

(b) the Metered Volume Reallocation Notification is submitted within the period of effectiveness of such MVRNA Authorisation; and

3.3.5 Where a valid Metered Volume Reallocation Notification (the "second" such notification) is submitted for which the relevant Metered Volume Reallocation Notification Agent, BM Unit and Subsidiary Energy Account are the same as those for an earlier-submitted Metered Volume Reallocation Notification (the "first" such notification):

(a) if the second notification specifies (pursuant to paragraph 3.3.2(c)(i)) that it is to replace the first notification, and either

(i) the Effective-from Date of the second notification is the same as or prior to the Effective-to Date of the first notification; or

(ii) the first notification has no Effective-to Date;

then, with effect from the Effective-from Date of the second notification (or, if later, the first Settlement Period from which it is in force pursuant to paragraph 1.2.4), the second notification shall replace the first notification and the first notification shall cease to be in force (or if it is not yet in force, shall not come into force), irrespective of whether the Effective-from Date of the first notification falls before or after the Effective-to Date of the second notification;

(b) otherwise, the second notification shall be additional to the first, and the first notification shall (subject to any other provision of this Section P) remain in (or, as the case may be, come into) force.

3.3.6 Subject to paragraph 3.3.10, a Metered Volume Reallocation Notification may not be amended or varied other than pursuant to paragraph 3.3.5(a).

3.3.7 The Energy Contract Volume Aggregation Agent shall:

(a) validate (as to compliance with the requirements in paragraph 3.3.4) each Metered Volume Reallocation Notification submitted to it pursuant to this paragraph 3.3; and

(b) determine whether such Metered Volume Reallocation Notification is to be treated as refused in accordance with paragraph 3.5.1.

3.3.8 Subject to paragraph 3.3.11, the ECVAA will inform the Lead and Subsidiary Parties and the relevant Metered Volume Reallocation Notification Agent if it does not validate a Metered Volume Reallocation Notification submitted to it pursuant to this paragraph 3.3.

3.3.9 If:

(a) a Metered Volume Reallocation Notification Agent submits a Metered Volume Reallocation Notification (the "original" such notification) which is not valid as provided in paragraph 3.3.4, and

(b) the ECVAA does not so inform the relevant Metered Volume Reallocation Notification Agent pursuant to paragraph 3.3.8 within 20 minutes after the Metered Volume Reallocation Notification was received,

then (subject to paragraph 3.3.11) paragraph 3.3.10 shall apply.

3.3.10 In the circumstances in paragraph 3.3.9:

(a) the Metered Volume Reallocation Notification may be:

(i) amended but only so as to correct those matters which gave rise to the invalidity as provided in paragraph 3.3.4, and

(ii) resubmitted (as so amended) by that Metered Volume Reallocation Notification Agent at any time not later than the end of the Business Day next following:

(1) the day on which the ECVAA did inform the Metered Volume Reallocation Notification Agent pursuant to paragraph 3.3.8, or

(2) in the absence of the ECVAA so informing the Metered Volume Reallocation Notification Agent, Gate Closure for the first Settlement Period for which the Metered Volume Reallocation Notification would (if valid, and in accordance with paragraph 1.2.4 where applicable) have been taken into account in Settlement; and

(b) the resubmitted Metered Volume Reallocation Notification:

(i) shall be deemed (for the purposes of the Code) to have been received at the time at which the original such notification was received; and

(ii) if valid in accordance with paragraph 3.3.4, shall, notwithstanding it may be submitted after Gate Closure for any such Settlement Period, be in force and (subject to paragraph 3.5) effective for Settlement Periods for which the original Metered Volume Reallocation Notification would (consistent with paragraph 1.2.4) have been in force.

3.3.11 To the extent that a Lead or Subsidiary Party or Metered Volume Reallocation Notification Agent has requested the ECVAA not to give the information in paragraph 3.3.8, paragraphs 3.3.8, 3.3.9 and 3.3.10 shall not apply in relation to that Party or Agent.

3.4 Not Used

3.5 Refusal and rejection for credit reasons

3.5.1 Where either the Lead Party or the Subsidiary Party is in Level 2 Credit Default in accordance with Section M3, a relevant Metered Volume Reallocation Notification which is submitted during the Credit Default Refusal Period will be treated as refused and will not become effective.

3.5.2 Where:

(a) a relevant Metered Volume Reallocation Notification is in force; and

(b) either the Lead Party or the Subsidiary Party is in Level 2 Credit Default in accordance with Section M3.

such Metered Volume Reallocation Notification will be treated as rejected, and will have no effect, as to Metered Volume Reallocation Data which relate to relevant Settlement Period(s) (as defined in paragraph 3.5.3) for which Gate Closure falls within the Credit Default Rejection Period.

3.5.3 For the purposes of this paragraph 3.5, a relevant Metered Volume Reallocation Notification is one which, if in force, and not treated as rejected in relation to a Settlement Period (a "relevant" Settlement Period), would have the effect in relation to that Settlement Period of increasing the Energy Indebtedness (in accordance with Section M1.2) of the Party in Level 2 Credit Default.

3.6 Metered Volume Reallocation Data

3.6.1 A Metered Volume Reallocation Notification shall specify for each Settlement Period:

(a) a MWh value, with no more than three digits after the decimal point, between –99,999.999 and 99,999.999; and

(b) a percentage value, non-negative, with no more than five digits after the decimal point and not exceeding 100;

but for the avoidance of doubt any such data may have zero values; and (subject to paragraph 1.2.5) where in relation to a Settlement Period no value for such data is specified, a value of zero shall be deemed to be specified.

3.6.2 In relation to the Subsidiary Energy Account (‘a’), for each Settlement Day or (pursuant to paragraph 1.2.4 or 3.5.2) part thereof for which a Metered Volume Reallocation Notification is in force and not treated as rejected pursuant to paragraph 3.5.2, for each matched Settlement Period specified in that Metered Volume Reallocation Notification:

(a) the Metered Volume Reallocation Fixed Data specified pursuant to paragraph 3.6.1(a) shall be "QMFR_ziaj";

(b) the Metered Volume Reallocation Percentage Data specified pursuant to paragraph 3.6.1(b) shall be "QMPR_ziaj";

4. AGGREGATION

4.1 Aggregation of Energy Contract Volumes

4.1.1 For each Energy Account and each Settlement Period, the Account Bilateral Contract Volume QABC_aj shall be determined according to the following formula:

QABC_aj = Σ_{b, z} ECQ_zabj – Σ_b,z ECQ_zbaj

where:

(a) the summations on z extend to all Energy Contract Volume Notifications in force, and

(b) the summations on b extend to all Energy Accounts of all Contract Trading Parties.

4.2 Exclusion of certain Metered Volume Reallocations

4.2.1 Where, in relation to any BM Unit and any Settlement Period, the sum (the ‘aggregate percentage data’ or "APD") of all values of QMPR_ziaj for all Metered Volume Reallocation Notifications and all Energy Accounts exceeds 100, values of that term:

(a) in the inverse of the chronological order in which the Metered Volume Reallocation Notifications were submitted (so that the data in the most recently submitted shall be the first to be disregarded), and

(b) until the value of APD (determined excluding the disregarded values of QMPR_ziaj) is not greater than 100,

shall be disregarded and shall not take effect for Settlement as to that Settlement Period.

4.3 Aggregation of Metered Volume Reallocations

4.3.1 For each BM Unit i, Subsidiary Energy Account a, and Settlement Period j, the Metered Volume Fixed Reallocation (QMFR_iaj) and Metered Volume Percentage Reallocation (QMPR_iaj) shall be determined as follows:

QMFR_iaj = Σ_z QMFR_ziaj

QMPR_iaj = Σ_z QMPR_ziaj

where in each case the summation on z extends to all Metered Volume Reallocation Notifications in force.

4.4 Determination and submission of aggregated data

4.4.1 The Energy Contract Volume Aggregation Agent shall:

(a) determine, for each Settlement Period, Metered Volume Fixed Reallocations, Metered Volume Percentage Reallocations and Account Bilateral Contract Volumes; and

(b) no later than the Business Day following the Settlement Day, submit such Metered Volume Fixed Reallocations, Metered Volume Percentage Reallocations and Account Bilateral Contract Volume data to the SAA.

4.4.2 Where, following the resolution of a Trading Dispute (but not for the avoidance of doubt in the circumstances described in Section M3.5), any adjustment or other change is to be made in any of the data referred to in paragraph 4.4.1 in relation to a Settlement Day, the ECVAA shall:

(a) make such adjustment or other change, and

(b) resubmit such data (as so adjusted or changed) to the SAA not later than the time required for such data to be taken into account in the next following Reconciliation Settlement Run (whether or not a Timetabled Reconciliation Settlement Run) for the relevant Settlement Day.

4.4.3 The ECVAA shall submit to BSCCo each month such data concerning Metered Volume Fixed Reallocations, Metered Volume Percentage Reallocations and Account Bilateral Contract Volumes as BSCCo requires to enable it to make the calculations required under Section D.

4A NULLIFICATION OF VOLUME NOTIFICATIONS

4A.1 Submission of a Volume Notification Nullification Request

4A.1.1 A request to nullify Energy Contract Volume Notifications and Metered Volume Reallocation Notifications may be submitted in accordance with this paragraph 4A to the ECVAA by either Contract Trading Party to whom the notifications relate (a "Volume Notification Nullification Request" (VNNR)).

4A.1.2 A VNNR must:

(a) specify:

(i) where Energy Contract Volume Notifications are in force between the relevant Contract Trading Parties, the Energy (From) Account and Energy (To) Account; and

(ii) where Metered Volume Reallocation Notifications in force between the relevant Contract Trading Parties, the Lead Energy Account and Subsidiary Energy Account,

in relation to which all notified volumes are to be nullified;

(b) specify the intended first effective Settlement Day and Settlement Period (the "Nullification Effective Period"); and

4A.2 Validity of a VNNR

4A.2.1 A VNNR shall be valid if and only if:

(a) it is made in accordance with paragraph 4A.1; and

(b) all ECVNA Authorisations and MVRNA Authorisations between the accounts specified in accordance with paragraph 4A.1.2(a), have been terminated in accordance with paragraphs 2.2 and 3.2 (as applicable).

4A.2.2 The ECVAA shall, in accordance with BSCP71, assess the validity of each VNNR.

4A.2.3 For the avoidance of doubt, a VNNR subsequently submitted in relation to the accounts specified in accordance with paragraph 4A.1.2(a) will replace the first Confirmed VNNR unless the VNNR specifies a later Nullification Effective Period or is invalid.

4A.3 Amendment of a VNNR

4A.3.1 Where there is an error in a submitted VNNR, the Contract Trading Party which submitted the VNNR may amend and re-submit the VNNR so as to rectify such error at any time prior to the ECVAA issuing a Volume Notification Nullification Confirmation Report ("VNNCR") in respect of the original VNNR pursuant to paragraph 4A.4.

4A.3.2 Where a VNNR is re-submitted in accordance with 4A.3.1, the time of receipt of a VNNR for the purposes of paragraph 4A.4 shall be the time of receipt of the last VNNR re-submitted in accordance with paragraph 4A.3.1.

4A.4 ECVAA confirmation

4A.4.1 The ECVAA shall issue a VNNCR:

(a) if valid receipt of a VNNR occurs between 0900 hours and 1600 hours (inclusive) on a Business Day, within one hour of such valid receipt; or

(b) if valid receipt of a VNNR occurs between 1600 hours and 1700 hours on a Business Day, within a period of 60 successive minutes where each minute falls during a Business Day. Such period shall commence on valid receipt of a VNNR and end during the first hour of the next Business Day; or in all other cases

4A.4.2 For the purposes of this paragraph 4A.4, references to a Business Day shall mean the period between 0900 hours and 1700 hours (inclusive) on a Business Day.

4A.4.3 At the time of issue of the VNNCR, the VNNR becomes the Confirmed VNNR.

4A.4.4 If the Confirmed VNNR is:

(a) not valid, the VNNCR shall be issued only to the Contract Trading Party which submitted the Confirmed VNNR and shall state the reason(s) why it is not valid;

(b) valid:

(i) the VNNCR shall be issued to both Contract Trading Parties to whom the Confirmed VNNR relates;

(ii) the VNNCR shall state the Valid Nullification Effective Period; and

(iii) the ECVAA shall commence nullification of all Energy Contract Volumes and Metered Volume Reallocations between the accounts specified in accordance with paragraph 4A.1.2(a), with effect from the Valid Nullification Effective Period.

4A.5 Notification of completion of process

4A.5.1 The ECVAA shall, in accordance with BSCP71, provide confirmation to both Contract Trading Parties to whom the Confirmed VNNR relates upon completion of the nullifications detailed in 4A.4.4(b).

5. FAILURES OF THE ECVAA SYSTEM

5.1 Introduction

5.1.1 For the purposes of this Section P:

(a) "Volume Notification" means an Energy Contract Volume Notification and/or a Metered Volume Reallocation Notification, and "Volume Notification Agent" means an Energy Contract Volume Notification Agent and/or a Metered Volume Reallocation Notification Agent;

(b) the "ECVAA System" is the BSC Agent System of the ECVAA, which for the avoidance of doubt does not include hardware or software forming part of any relevant Communications Medium;

(c) an "ECVAA System Failure" is a failure or breakdown of the ECVAA System which has the effect that the ECVAA is unable to receive Volume Notifications submitted to it by all or any Volume Notification Agents, and/or (as the case may be) to send within 20 minutes after such receipt confirmations of such receipt to all or any such agents;

(d) the reference in paragraph (c) to the ECVAA sending confirmations of receipt of Volume Notifications is without prejudice to the provisions of the Communications Requirements Document as to the deemed receipt of such notifications;

(e) for the avoidance of doubt, no failure or breakdown of any Party System or any communications link not forming part of the ECVAA System shall be counted as an ECVAA System Failure;

(f) in relation to an ECVAA System Failure:

(i) the "system failure time" is the start of the ECVAA System Failure, or such earlier time as BSCCo may determine as being appropriate for the purposes described in paragraph (g) and notify to the ECVAA, Contract Trading Parties and Volume Notification Agents;

(ii) the "resubmission deadline" is the end of the Business Day following the day on which the ECVAA notified BSCCo (in accordance with paragraph 5.2.1(c)(i)) that the ECVAA System Failure has ended, or such earlier time (not being earlier than such failure ended) or later time as BSCCo may determine as being appropriate for the purposes described in paragraph (g) and notify to the ECVAA, Contract Trading Parties and Volume Notification Agents;

(g) the purposes referred to in paragraph (f) are to enable Contract Trading Parties and their Volume Notification Agents to take steps to put themselves, so far as is practicable, in the position as respects the submission of Volume Notifications which they would have been had the ECVAA System Failure not occurred.

5.2 Consequences of ECVAA System Failure

5.2.1 Where an ECVAA System Failure occurs:

(a) the ECVAA shall as soon as possible notify BSCCo of the failure and the time at which it started;

(b) the ECVAA and BSCCo shall each use all reasonable efforts as soon as practicable to notify all Contract Trading Parties and Volume Notification Agents of the failure and the time at which it started;

(i) the ECVAA shall notify BSCCo, Contract Trading Parties and Volume Notification Agents that the failure has ended;

(ii) BSCCo will notify Contract Trading Parties and Volume Notification Agents that Volume Notifications may be submitted or resubmitted in accordance with paragraph 5.2.2.

5.2.2 Where an ECVAA System Failure has occurred, commencing at the end of such failure, and until the resubmission deadline, Volume Notifications may be submitted or resubmitted to the ECVAA in relation to any Settlement Period for which Gate Closure falls after the system failure time and before the resubmission deadline.

5.2.3 Where an ECVAA System Failure affects the ability of the ECVAA to receive and/or confirm receipt of Volume Notifications (as described in paragraph 5.1.1(c)) from or to some but not all Volume Notification Agents:

(a) the ECVAA shall inform BSCCo which Volume Notification Agents are so affected, and references in paragraph 5.2.1 to Volume Notification Agents shall only be to those agents so affected;

(b) paragraph 5.2.2 shall apply only in relation to the affected Volume Notification Agents.

5.2.4 Any Volume Notification submitted or resubmitted in accordance with paragraph 5.2.2 shall specify the details (as provided in paragraph 2.3.2 or 3.3.2) which were or would (pursuant to commitments made before Gate Closure for any Settlement Period to which such notification relates) have been specified in such notification if it had been submitted before Gate Closure for any Settlement Period to which it relates (and if any question arises in relation to this paragraph 5.2.4, such question shall be decided by the Panel whose decision shall be final and binding on all Parties).

5.2.5 For the avoidance of doubt the existence of an ECVAA System Failure which is known to BSCCo shall constitute a material doubt as referred to in Section M3.4.3(a) in relation to all Trading Parties, except (in relation to a particular Trading Party) in a case where BSCCo is aware that such Party has not appointed any of the Volume Notification Agents affected thereby.

5.2.6 If any Contract Trading Party or Volume Notification Agent considers that:

(a) an ECVAA System Failure has occurred which has not been notified under paragraph 5.2.1(b), or

(b) the ECVAA has given notice under paragraph 5.2.1(c)(i) at a time at which the ECVAA System Failure has not ended, or

(c) (in the case of such an agent, where paragraph 5.2.3 applies) that it was not but should have been informed that it is affected as described in that paragraph;

such Party or agent may so notify BSCCo, as soon as reasonably practicable and in any event not later than the end of the Business Day following the day on which the Party or agent considers that the ECVAA System Failure occurred, or (in a case in paragraph (b)) after the day on which the ECVAA gave notice as therein mentioned.

5.2.7 Upon any Party or Volume Notification Agent giving notification to BSCCo in accordance with paragraph 5.2.6:

(a) BSCCo shall:

(i) notify the ECVAA,

(ii) promptly investigate the matter, and

(iii) determine whether an ECVAA System Failure occurred, or whether the failure had ended, or whether such agent was affected, each as referred to in paragraph 5.2.6;

(b) the ECVAA and upon request any Party or Notification Agent shall provide reasonable assistance to BSCCo in such investigation;

(d) BSCCo's determination of such matters shall be final and binding for the purposes of this paragraph 5.2;

(e) where BSCCo determines that an ECVAA System Failure has occurred, BSCCo may determine and notify the resubmission deadline at any time at which it appears to BSCCo that the ECVAA System Failure has ended.

5.3 ECVAA System Withdrawal

5.3.1 Where:

(a) there occurs or has occurred any partial ECVAA System Failure (that is, such a failure affecting some but not all Volume Notification Agents, and/or affecting only the ability of the ECVAA to receive or its ability to confirm receipt (as described in paragraph 5.1.1(c)) of Volume Notifications) and/or any failure or breakdown of the ECVAA System affecting the ability of the ECVAA to provide information of invalidity of Volume Notifications within the timescales contemplated in paragraph 2.3.9(b) and 3.3.9(b), and

(b) the ECVAA or BSCCo determines (in its reasonable opinion) that, in order to minimise disruption to the smooth and efficient implementation of Contract Trading Parties' operations under this Section P and of Settlement, it is necessary:

(i) to withdraw the ECVAA System from operation in order to remedy such failure or breakdown and/or to implement the provisions of paragraph 5.2 (in the case of an ECVAA System Failure giving rise to the application of such provisions); and

(ii) to do so earlier than might otherwise be done by way of planned BSC Agent downtime in accordance with the Communications Requirement Document

then the ECVAA shall withdraw the ECVAA System from operation, for the purposes of remedying the failure or breakdown and/or implementing the provisions of paragraph 5.2.

5.3.2 Where the ECVAA withdraws the ECVAA System from operation pursuant to paragraph 5.3.1:

(a) the ECVAA shall, not later than the time of such withdrawal, give notice thereof to BSCCo specifying the time of such withdrawal;

(b) the ECVAA shall restore the ECVAA System to operation as soon as reasonably practicable, having regard to the purposes (described in paragraph 5.3.1(b)) for which it was withdrawn from operation;

(c) in order to enable Volume Notifications to be submitted to the ECVAA in respect of the period of withdrawal, paragraphs 5.1.1(f) and 5.2 (excluding paragraphs 5.2.1(a), 5.2.3, 5.2.6 and 5.2.7) shall apply as if references in those paragraphs:

(i) to the ECVAA System Failure (or the start of such failure) were to the withdrawal from operation of the ECVAA System;

(ii) to the end of the ECVAA System Failure were to the restoration to operation of the ECVAA System.

1.2 Interpretation

1.2.1 In this Section Q:

(a) at or in relation to a particular time and in relation to a particular data item, "prevailing" means most recently received by the NETSO in accordance with the Grid Code (and not invalidated thereunder) prior to that time or, in the absence of any such receipt and/or during a period of Outage, determined (where applicable) by the NETSO in accordance with the Grid Code;

(b) subject to paragraph 1.2.4, references to a "relevant BM Unit" are to a BM Unit in respect of which the Lead Party wishes to submit Bid-Offer Pairs or a Replacement Reserve Bid from time to time under the Code;

(c) an "Outage" means any withdrawal by the NETSO (for maintenance or otherwise), breakdown or failure of any electronic data communications systems by which the NETSO receives and accesses communications made by Lead Parties, where such withdrawal, breakdown or failure has (and for so long as it has) the effect that all Lead Parties are unable to submit Physical Notifications, Bid-Offer Data, Replacement reserve Bid Data or the NETSO is unable to receive or access such data submitted by all Lead Parties;

(d) references to the period of Outage shall be to the period commencing at the time when such Outage first occurs and ending at the time when the NETSO’s ability to receive and access Physical Notifications, Bid-Offer Data and Replacement Reserve Bid Data is restored.

1.2.2 In respect of the submission of data and the making of other communications under this Section Q:

(a) where a Party (other than the NETSO) or the NETSO is entitled or obliged to submit data items to, or otherwise to communicate with, the NETSO or such a Party (respectively) in accordance with the Grid Code, such submission or communication shall be:

(i) in accordance with the communications requirements; and

(ii) subject to the rules as to when and whether data or communications are treated as received,

set out in the Grid Code;

(b) the NETSO shall ensure that it has appropriate systems and processes in place for the purposes of receiving and responding to the data items to be submitted by Lead Parties, and otherwise communicating with Lead Parties, pursuant to or as contemplated by this Section Q; and

(c) where the NETSO is entitled or obliged to submit data items to a BSC Agent, such submission shall be subject to and in accordance with the provisions of Section O.

1.2.3 For the avoidance of doubt:

(a) the Final Physical Notification Data, the Bid-Offer Data and the Acceptance Data submitted by the NETSO pursuant to this Section Q shall be converted into point values by the SAA and the BMRA in accordance with the provisions of Section T and Section V respectively; and

(b) the Final Physical Notification Data submitted by the NETSO pursuant to this Section Q shall be converted into point values by the ECVAA in accordance with the provisions of this Section Q.

1.2.4 From the first occasion on which the Lead Party submits any Bid-Offer Pair in respect of a BM Unit, by virtue of arrangements (for the determination of default data) applying under the Grid Code, the BM Unit will be and at all times continue to be a relevant BM Unit, unless the Lead Party takes any such steps as may be available in accordance with the Grid Code to discontinue the application of such default data arrangements.

1.2.5 The NETSO shall notify BSCCo (as soon as reasonably practicable after the information is available):

(a) of any notice given by the NETSO to Users under the Grid Code that an Outage is to occur and of the period of notice given;

(b) of the time when an Outage occurs;

1.3 Data submission by the NETSO

1.3.1 Where under this Section Q the NETSO is required to send particular data to:

(a) both the BMRA and SAA; or

(b) both the BMRA and the ECVAA

8.1.3 If any dispute arises in connection with this paragraph 8 as to the time of commencement of an Outage, or the period of such an Outage, the Panel shall determine the matter in dispute after consultation with the NETSO and the Party raising the dispute, and the Panel's determination shall be final and binding for the purposes of this paragraph 8.

8.2 Claim for compensation following unplanned outage

8.2.1 Subject to the provisions of the Code, following an outage compensation period, a Party which:

(a) is the Lead Party of any BM Unit(s); and

(b) considers:

(i) it suffered (consistent with the matters set out in paragraph 8.2.5) a material loss, which it could not reasonably have avoided, as a result of its inability to submit Physical Notifications during an outage compensation period; or

(ii) where a Metered Volume Reallocation Notification(s) is in force for any BM Unit(s), that collectively it and all Subsidiary Parties in relation to any BM Unit ("relevant" Subsidiary Parties for the purposes of this paragraph 8) suffered (consistent with the matters set out in paragraph 8.2.5) a net material loss, which could not reasonably have been avoided, as a result of its inability to submit Physical Notifications during an outage compensation period,

may, within the period of ten Business Days after the end of the compensation outage period, submit to BSCCo a claim for payment of compensation to be determined in accordance with this paragraph 8.2.

8.2.1A The Party shall, at the time at which it submits a claim under paragraph 8.2.1:

(a) provide a statement and explanation of the basis on which it considers that it has or it and all relevant Subsidiary Parties have suffered such a loss as is referred to in paragraph 8.2.1; and

8.2.4 Where the Panel determines (in accordance with paragraph 8.2.2) to consider the Party's claim, the Panel shall determine, in its opinion, the amount of the loss:

(a) which was suffered by the Party and any relevant Subsidiary Party; and

(b) which the Party and any relevant Subsidiary Party could not reasonably have avoided,

as a result of the Party's inability to submit or resubmit Physical Notifications during the outage compensation period.

8.2.5 In determining the amount (if any) of the loss suffered by a Party and any relevant Subsidiary Party, and whether and the extent to which the Party and any relevant Subsidiary Party could reasonably have avoided such loss, the Panel shall have regard to the following:

(a) whether and the extent to which, in the opinion of the Panel, the net financial position of the Party together with all relevant Subsidiary Parties, in respect of Trading Charges, was worse than the net financial position of the Party together with all relevant Subsidiary Parties, in respect of Trading Charges and Avoidable Costs, would have been if the Party had been able to submit or resubmit Physical Notifications during the outage compensation period; where Avoidable Costs refers to Avoidable Costs which would have been incurred in respect of changes which would (if the Party had so been able) have occurred in Exports and/or Imports of the BM Units of which the Party is Lead Party; and

(b) whether and the extent to which, in the opinion of the Panel, the Party acted reasonably and prudently in making commitments which resulted in notification of Energy Contract Volumes relating to relevant Settlement Periods, and otherwise in its operations under the Grid Code and the Code;

and the Panel shall disregard costs and losses (including in respect of amounts payable in respect of such commitments as are referred to in paragraph (b)) other than those referred to in paragraph (a).

SECTION R: COLLECTION AND AGGREGATION OF METER DATA FROM CVA METERING SYSTEMS

1. INTRODUCTION

1.1 General

1.1.1 This Section R provides for the determination of Metered Volumes for the purposes of Central Volume Allocation in respect of:

(a) BM Units other than Interconnector BM Units, Supplier BM Units and Secondary BM Units (in this Section R, "relevant" BM Units);

(b) Interconnectors;

(d) GSP Groups;

(collectively referred to as "Volume Allocation Units" for the purposes of this Section R).

1.1.2 This Section R accordingly sets out:

(a) the basis on which data registered in CRS and Meter Technical Details will be submitted to and validated by the CDCA;

(b) requirements for Parties to prepare Aggregation Rules and submit such rules to the CDCA, and for the validation of such rules;

(c) the basis on which Line Loss Factors will be submitted to CDCA for CVA Metering Systems connected to Distribution Systems; and

(d) the basis on which the CDCA will collect and validate or (where necessary) estimate metered data from Metering Systems, aggregate such data to determine Metered Volumes, and submit such Metered Volumes to the SAA and/or SVAA.

1.1.3 This Section R applies only in relation to CVA Metering Systems (and references in this Section R to Metering Systems shall be construed accordingly).

1.1.4 Paragraph 7 of this Section R provides for the determination of BM Unit Metered Volumes in respect of Interconnector BM Units (other than those for which an Interconnector Error Administrator is Lead Party); and further references to BM Units in paragraphs 1 to 6 do not include Interconnector BM Units.

1.2 Metered Volumes

1.2.1 For the purposes of this Section R, in relation to a Volume Allocation Unit and a Settlement Period, the "Metered Volume" is the net aggregate volume of Active Energy, determined as at the Transmission System Boundary, which flowed in that Settlement Period to or from that Volume Allocation Unit.

1.3 Settlement Calendar

1.3.1 The CDCA shall undertake its duties under this Section R as to the collection, validation, estimation and aggregation of metered data, and the submission of such data to certain Parties and other BSC Agents, in accordance with BSCP01 and the prevailing Settlement Calendar.

1.4 Requirements for data collection

1.4.1 The CDCA shall collect or procure the collection of metered data (as required by paragraph 5) available from Outstations either by means of remote interrogation or by means of manual on-site interrogation.

1.4.2 The CDCA shall be responsible for the operation and maintenance of Communications Equipment (other than modems or equivalent exchange links) after it has been installed by the Registrant in accordance with Section L; and for the purposes of remote interrogation the CDCA shall enter into, manage and monitor contracts or other arrangements to provide for the maintenance of all communication links which form part of such Communications Equipment.

1.4.3 In the event of any fault or failure of any communication link or any error or omission in such data or all necessary data not being available from Outstations the CDCA shall collect or procure the collection of such data by manual on-site interrogation.

1.4.4 The CDCA shall cease to be required to maintain communications links in respect of Metering Equipment if, and with effect from the date when, the Metering System ceases to be registered in CMRS.

1.4.5 The CDCA shall be responsible for the installation and maintenance of central collector stations.

1.4.6 Communications Equipment need not be dedicated exclusively to the provision of data to the CDCA for the purposes of Central Volume Allocation, provided that any other use shall not interfere at any time with the operation of the Central Volume Allocation processes.

1.4.7 The CDCA shall comply (without charge to the Registrant) with any reasonable request by the Registrant to provide access to Communications Equipment to the Registrant and to other persons nominated by the Registrant (including for the purposes of complying with the Registrant's obligations under Section L5.2).

1.5 Objective of CDCA

1.5.1 The CDCA shall carry out its functions under this Section R with the objective of ensuring that all exports and imports at CVA Boundary Points and Systems Connection Points are properly and accurately taken into account and allocated to the responsible Party in Central Volume Allocation.

1.6 Interpretation

1.6.1 For the purposes of this Section R:

(a) "metered data" means data, relating to a flow (by way of import or export) of Active Energy or Reactive Energy, derived from any meter register of any Metering System;

(b) where the context admits, a reference to metered data shall include estimated data;

(d) "reactive energy metered data" is metered data relating to a flow of Reactive Energy;

(e) unless the context otherwise requires, references to metered data are to active energy metered data only; and

(f) "import" and "export" shall be construed as including (in addition to Import and Export in accordance with Section K) a flow of electricity at a Systems Connection Point to or from a given System.

1.6.2 No provision of this Section R (including without limitation paragraphs 1.5 and 3.1.4(a)(iii)) shall be construed as requiring anything to be done which could not be done without the existence of Aggregation Rules specifying data or operations beyond what is permitted to be specified in accordance with paragraph 3.3.1.

2. REGISTRATION AND TECHNICAL DETAILS

2.1 Registration Data

2.1.1 Data registered in CRS will be submitted by the CRA to the CDCA pursuant to Section K6.

2.1.2 The CDCA shall:

(a) validate (as to completeness and form) registration data submitted to it by the CRA;

(b) record and maintain such validated data; and

(c) where the CRA fails to submit any registration data to the CDCA, or any registration data which is submitted fails validation, so inform the CRA and request the CRA to submit or correct and submit the registration data.

2.2 Meter Technical Details

2.2.1 Meter Technical Details for each CVA Metering System will be submitted to the CDCA by the Registrant in accordance with BSCP20 and pursuant to Section L2.4.1(c).

2.2.2 The CDCA shall:

(a) validate (as to completeness and form) Meter Technical Details submitted to it;

(b) record and maintain in CMRS such validated data; and

(c) where the Registrant fails to submit any Meter Technical Details to the CDCA, or any Meter Technical Details which are submitted fail validation, so inform the Registrant and request the Registrant to submit or correct and submit the Meter Technical Details.

3. AGGREGATION RULES

3.1 General

3.1.1 For the purposes of the Code "Aggregation Rules" relating to a Volume Allocation Unit are rules by reference to which import or export active energy metered data collected from Outstations relating to meter registers of one or more Metering Systems are to be aggregated so as to provide, in relation to any Settlement Period, the Metered Volume for that Volume Allocation Unit for the purposes of Settlement.

3.1.2 For the purposes of this Section R, references to the "aggregation" of metered data are to the application to such data of any one or more of the arithmetic operations referred to in paragraph 3.3.1(b) (and 'aggregate' and 'aggregated' shall be construed accordingly).

3.1.3 Aggregation Rules must comply with the applicable requirements and criteria in paragraph 3.3.

3.1.4 Where under this Section R a Party is required to prepare and submit to the CDCA any Aggregation Rules in relation to any Volume Allocation Unit:

(a) the Party shall prepare such rules:

7.1 General

7.1.1 This paragraph 7 sets out the basis on which (subject to paragraph 7.1.2) BM Unit Metered Volumes will be determined for each Interconnector BM Unit in respect of each Interconnector.

7.1.2 BM Unit Metered Volumes for the Interconnector BM Units for which the Interconnector Error Administrator is Lead Party will be determined (inter alia, using the Interconnector Metered Volume) in accordance with Section T4.1 and not this paragraph 7, and accordingly:

(a) references in this paragraph 7 to Interconnector BM Units do not include the Interconnector BM Units of which the relevant Interconnector Error Administrator (in that capacity) is Lead Party;

(b) the Interconnector Metered Volume (determined under paragraph 5) is not used for the purposes of this paragraph 7.

7.1.3 For the purposes of this paragraph 7:

(a) the "Interconnector Scheduled Transfer" for each Interconnector in relation to a Settlement Period is the Active Energy flow, scheduled for all Interconnector Users (and not exceeding the physical capability of the Interconnector as from time to time determined under the relevant Interconnection Agreements), across the Interconnector (as a whole), as established pursuant to the relevant Interconnection Agreements between the Interconnected System Operator and the Externally Interconnected System Operator, stated as at the Transmission System Boundary, in the form of a schedule expressed as MW values for the spot times at the start and end of, and other spot times within, the Settlement Period;

(b) after Gate Closure in relation to any Settlement Period, the Interconnector Scheduled Transfer is to be adjusted to reflect:

(i) any failure or derating of the physical capability of the Interconnector (as determined under the relevant Interconnection Agreements), and any subsequent uprating of the physical capability of the Interconnector provided that the uprated capability does not exceed the Interconnector Scheduled Transfer established at Gate Closure;

(ii) the acceptance by the NETSO of any Offer or Bid submitted by an Interconnector User in respect of an Interconnector BM Unit;

(iii) any event occurring in relation to an External System, to the extent so provided in the relevant Interconnection Agreements, as notified to the Interconnector Administrator; or

(iv) in relation to an Interconnector, the results of Single Intraday Coupling provided that such adjustment shall be made following the Intraday Cross-Zonal Gate Closure Time for the relevant Settlement Period,

but shall not otherwise be adjusted;

(c) the "final" Interconnector Scheduled Transfer in relation to a Settlement Period is the Interconnector Scheduled Transfer prevailing at the end of that Settlement Period;

(d) for each Interconnector BM Unit:

(i) the "Expected Transfer" in relation to a Settlement Period is a schedule of expected Active Energy flows, stated as at the Transmission System Boundary, expressed as MW values for the spot times at the start and end of, and other spot times within, the Settlement Period;

(ii) in the case of a Production BM Unit, the Expected Transfer shall relate only to Exports;

(iii) in the case of a Consumption BM Unit, the Expected Transfer shall relate only to Imports.

(e) for the purposes of an Interconnector Scheduled Transfer and an Expected Transfer, MW values are to be specified at particular spot times during (and including the start and end of) the relevant Settlement Period, and MW values at other spot times shall be established by linear interpolation.

7.1.4 For any Interconnector:

(a) the sum of the Expected Transfers (for any spot time in the relevant Settlement Period) for all Interconnector BM Units shall be equal to the Interconnector Scheduled Transfer for that spot time;

(b) wherever the Interconnector Administrator is to determine or adjust Expected Transfers, the Interconnector Administrator shall adjust the MW values in the Expected Transfers (by reference to capacity entitlements under and/or other applicable provisions of the relevant Interconnection Agreements) as required to ensure that paragraph (a) is satisfied.

7.1.5 In any case where Section H3.2.2(c) applies in relation to an Interconnector User, that Interconnector User shall be treated as having a zero Expected Transfer and the Expected Transfers for other Interconnector Users shall be determined (consistent with paragraph 7.1.4(a)) on that basis.

7.1.6 Without prejudice to Section U1.2, each Interconnector User shall ensure that all information provided pursuant to this paragraph 7 to the Interconnector Administrator is true, accurate and complete.

7.2.1 The Interconnected System Operator shall send or procure that there is sent to the Interconnector Administrator the Interconnector Scheduled Transfer prevailing at Gate Closure.

7.2.2 The Interconnector User for each Interconnector BM Unit shall send or procure that there is sent, no later than Gate Closure, to the Interconnector Administrator a copy of the Physical Notification prevailing at Gate Closure for each Settlement Period (and may do so by providing copies of Physical Notifications and changes thereto submitted at times before Gate Closure).

7.2.3 The Interconnector Administrator shall determine the Expected Transfer for each Interconnector BM Unit at Gate Closure, by reference to (and so that the MW values in the Expected Transfer are derived from) the Physical Notification prevailing at Gate Closure, subject to paragraph 7.1.4.

7.3 Adjustments after Gate Closure

7.3.1 Following Gate Closure and until the end of the Settlement Period:

(a) promptly upon any revision thereto, the Interconnected System Operator shall send or procure that there is sent to the Interconnector Administrator the revised Interconnector Scheduled Transfer;

(b) where the Interconnector Administrator is so notified of a revision to the Interconnector Scheduled Transfer, the Interconnector Administrator shall adjust the Expected Transfer(s) accordingly and consistent with paragraph 7.1.4, provided that:

(i) in the case of a revision to the Interconnector Scheduled Transfer under paragraph 7.1.3(b)(ii), only the Expected Transfer of the Interconnector User which submitted the Bid or Offer therein referred to shall be so adjusted;

(ii) in the case of a revision to the Interconnector Scheduled Transfer under paragraph 7.1.3(b)(iii), the Expected Transfer to be adjusted shall be that of the Interconnector User as determined and notified to the Interconnector Administrator in accordance with the applicable provisions of the relevant Interconnection Agreement;

(iii) in the case of a revision to the Interconnector Scheduled Transfer under paragraph 7.1.3(b)(iv), the Expected Transfer to be adjusted to reflect the results of Single Intraday Coupling shall be that of the Interconnector User as determined and notified to the Interconnector Administrator in accordance with the applicable provisions of the relevant Interconnection Agreement;

and the Non Half Hourly Data Collector shall recalculate the Fraction of Yearly Consumption upon receipt of any updated information in relation to any relevant Demand Disconnection Daily Profile Coefficients.

4.3.3A Each Supplier shall ensure that, in respect of each Settlement Day "T", each GSP Group "H" and each valid combination of Profile Class "P" and Time Pattern Regime within Standard Settlement Configuration "R", the relevant Non Half Hourly Data Collector responsible for a Metering System "K" shall determine a Demand Disconnection Daily Profile Coefficient (DDDPC_HPKRT) as:

DDDPC_HPKRT = Σ_j (PPCC_HPRj * (M_Kj / SPD))

where M_Kj shall be set to zero for any MSID notified under Section S9.3.1.

4.3.4 Each Supplier shall ensure that a value of Annualised Advance shall be determined from each Meter Advance by the relevant Non Half Hourly Data Collector responsible for each such Supplier’s metered Metering System "K" for each Settlement Register within such Metering System according to the following formula:

if FYC_KR ≠ 0 then:

AA_KR = MADV_KR / FYC_KR

where MADV_KR is the Meter Advance obtained by the relevant Non Half Hourly Data Collector for the same Meter Advance Period as employed in the determination of the Fraction of Yearly Consumption pursuant to paragraph 4.3.3;

but if FYC_KR = 0 then

AA_KR = 0

and the Effective From Settlement Date for each such value of Annualised Advance shall be the date of the first Settlement Day in the Meter Advance Period and the Effective To Settlement Date for each such value of Annualised Advance shall be the date of the last Settlement Day in the Meter Advance Period. Such values so determined shall replace any previous Annualised Advance, Effective From Settlement Date and Effective To Settlement Date determined for such Settlement Days.

4.3.5 NOT USED.

4.3.6 Each Supplier shall ensure that for each of its metered Metering Systems "K", a value for the Estimated Annual Consumption (EAC_KR) shall be determined by the relevant Non Half Hourly Data Collector responsible for such Metering System for each Settlement Register according to the formulae set out in paragraph 4.3.7.

4.3.7 For the purposes of this paragraph 4.3.7 the Previous Estimated Annual Consumption (PEAC_KR) shall be defined as the effective value of EAC_KR for each Settlement Day in the Meter Advance Period which applies before a new value is determined in accordance with this paragraph. An Annualised Advance Adjustment Factor (AAAF_KR) and a new Estimated Annual Consumption shall be determined as follows using the value of Annualised Advance determined pursuant to paragraph 4.3.4:

(a) AAAF_KR = max (0, min ((FYC_KR * SPAR), 1.0)); and

(b) EAC_KR = AAAF_KR * AA_KR + (1 - AAAF_KR) * PEAC_KR

where SPAR is the value of the Smoothing Parameter set from time to time by the Panel applicable on the last Settlement Day of the Meter Advance Period. The Effective From Settlement Date for each such value of Estimated Annual Consumption shall be the date of the Settlement Day following the last Settlement Day of the Meter Advance Period and shall replace any previous Estimated Annual Consumption effective on such Settlement Days.

4.3.8 Each Supplier shall ensure that for each of its metered Metering Systems "K" the Non Half Hourly Data Collector responsible for such Metering System shall provide the Annualised Advance and Effective From Settlement Date and Effective To Settlement Date, Estimated Annual Consumption and Effective From Settlement Date for each Settlement Register determined pursuant to paragraphs 4.3.4 and 4.3.7 to the relevant Non Half Hourly Data Aggregator responsible for such Metering System.

4.3.9 In the case where the Profile Class "P" of a metered Metering System "K" changes and the Settlement Day from which the change of Profile Class is effective does not fall in a Meter Advance Period, the Supplier responsible for such Metering System shall ensure that the Non Half Hourly Data Collector responsible for such Metering System shall for each Settlement Register provide (without adjustment) the initial value of Estimated Annual Consumption provided pursuant to paragraph 4.3.2(a) and its Effective From Settlement Date to the relevant Non Half Hourly Data Aggregator responsible for such Metering System. Such value shall on the Settlement Days it is effective replace the previous Estimated Annual Consumption effective on such Settlement Days. Once a Meter Advance has been calculated such that such change of Profile Class falls within such Meter Advance Period, the provisions of paragraph 4.3.10 shall apply to such Meter Advance.

4.3.10 In the case where the Profile Class "P" of a metered Metering System "K" changes and the date of the Settlement Day from which the new Profile Class takes effect falls in a Meter Advance Period, then the Supplier responsible for such Metering System shall ensure that the Non Half Hourly Data Collector responsible for such Metering System shall:

(a) determine the value of Annualised Advance for each Settlement Register pursuant to the provisions of paragraphs 4.3.3 to 4.3.4 (inclusive);

(b) not determine a value of Estimated Annual Consumption for any Settlement Register within such Metering System "K" and shall not set such value of Estimated Annual Consumption to zero;

(c) provide the value of Annualised Advance so calculated together with its Effective From Settlement Date and Effective To Settlement Date and send unadjusted the initial value of Estimated Annual Consumption provided pursuant to paragraph 4.3.2(a) and its Effective From Settlement Date to the relevant Non Half Hourly Data Aggregator responsible for such Metering System.

4.3.11 In the case where a metered Metering System "K" is a new Metering System for which a Meter Advance has not yet been calculated the Supplier responsible for such Metering System shall ensure that the Non Half Hourly Data Collector responsible for such Metering System shall set the value of Estimated Annual Consumption to be equal to the value of initial Estimated Annual Consumption provided by such Supplier pursuant to paragraph 4.3.2(a) for each Settlement Register and that such Non Half Hourly Data Collector shall pass such value unadjusted to the relevant Non Half Hourly Data Aggregator responsible for such Metering System. The Effective From Settlement Date for such Estimated Annual Consumption shall be the Settlement Day on which such Metering System is first energised, as determined from data provided by the relevant SMRA by reference to its Supplier Meter Registration Service system. The Supplier shall ensure that the relevant Non Half Hourly Data Collector shall not determine a value of Annualised Advance for such Settlement Register and shall not set the value of Annualised Advance to zero until a Meter Advance has been calculated. Once a Meter Advance has been calculated for such new metered Metering System, the provisions of paragraphs 4.3.3 to 4.3.8 (inclusive) shall apply.

4.3.12 In the case where for a metered Metering System "K" the physical meter changes or, as the case may be, is reconfigured, concurrently with a change to the associated Standard Settlement Configuration "C" and there is a Meter Advance Period ending on the Settlement Day before the physical meter changes or, as the case may be, is reconfigured, the Supplier responsible for such Metering System shall ensure that the Non Half Hourly Data Collector responsible for such Metering System shall determine the values of Annualised Advance and Estimated Annual Consumption for each old Settlement Register pursuant to paragraphs 4.3.3 to 4.3.7 (inclusive) and shall provide the Annualised Advance data together with its Effective From Settlement Date and Effective To Settlement Date for such old Settlement Register and, unadjusted, the initial Estimated Annual Consumption together with its Effective From Settlement Date provided by such Supplier pursuant to paragraph 4.3.2(a) for each new Settlement Register to the relevant Non Half Hourly Data Aggregator responsible for such Metering System. Such Non Half Hourly Data Collector shall not be obliged, however, to provide the Estimated Annual Consumption for the old Settlement Register determined pursuant to paragraph 4.3.7 to the relevant Non Half Hourly Data Aggregator responsible for such Metering System.

4.3.13 The provisions of this paragraph 4.3.13 shall apply in the case where there is a Meter Advance Period ending on the Settlement Day before there is a change of Supplier for a metered Metering System "K" and the metered Metering System "K" is not subject to half hourly metering on the Settlement Day of the change of Supplier. For this purpose a Meter Advance Period shall end, or as the case may be, shall be deemed to end on such Settlement Day before the change of Supplier in accordance with BSCP504. In this case:

(a) the old Supplier shall ensure that its Non Half Hourly Data Collector responsible for such Metering System shall:

(i) in accordance with BSCP504 and on request from the new Supplier’s Non Half Hourly Data Collector provide the Estimated Annual Consumption for each Settlement Register for such Metering System effective on such Settlement Day to the new Supplier's Non Half Hourly Data Collector responsible for such Metering System;

(ii) determine the values of Annualised Advance and Estimated Annual Consumption for each Settlement Register for such Metering System pursuant to paragraphs 4.3.3 to 4.3.7 (inclusive); and

4.3.13A The circumstances referred to in paragraph 4.3.13(c) are that the quantity of energy in respect of the Metering System is recorded by, and available from, a Meter:

(a) serviced by the DCC; or

(b) which has been installed in compliance with the Smart Metering Equipment Technical Specifications and the new Supplier and the old Supplier agree that the process in paragraph 4.3.13(c) shall apply.

4.3.14 The provisions of this paragraph 4.3.14 shall apply in the case where there is a Meter Advance Period ending on the Settlement Day before there is a change of Supplier for a metered Metering System "K", and the metered Metering System "K" is subject to half hourly metering on the Settlement Day of the change of Supplier. For this purpose a Meter Advance Period shall end, or as the case may be, shall be deemed to end on the Settlement Day before the change of Supplier in accordance with BSCP504. In this case, the old Supplier shall ensure that its Non Half Hourly Data Collector responsible for such Metering System shall:

(a) determine the values of Annualised Advance and Estimated Annual Consumption for each Settlement Register for such Metering System pursuant to paragraphs 4.3.3 to 4.3.7 (inclusive); and

(b) provide the value of Annualised Advance for each Settlement Register together with its Effective From Settlement Date and Effective To Settlement Date determined pursuant to paragraph (a) above, which values shall be attributable to the old Supplier, to the old Supplier's relevant Non Half Hourly Data Aggregators responsible for such Metering System.

4.3.15 Each Supplier shall ensure that for any metered Metering System "K" for which it is responsible and for which BSCP504 provides that a Deemed Meter Advance must or could be calculated for a Deemed Meter Advance Period such Deemed Meter Advance may (where BSCP504 provides that it may) and shall (where BSCP504 provides it must) be calculated for each Settlement Register in accordance with the following formulae:

(a) Where BSCP504 provides that the Deemed Meter Advance shall be calculated using an Estimated Annual Consumption:

DMA_{KR =} ∑_T (DPC_HPRT*EAC_KR)

where:

Σ_T DPC_HPRT is the sum of the individual Daily Profile Coefficients appropriate to the GSP Group, Time Pattern Regime, Standard Settlement Configuration and Profile Class applying to the Metering System on each Settlement Day in the applicable Deemed Meter Advance Period as set out in BSCP504.

(b) Where BSCP504 provides that the Deemed Meter Advance shall be calculated using an Annualised Advance:

DMA_KR = ∑_T(DPC_HPRT * AA_KR)

where:

Σ_TDPC_HPRT is the sum of the individual Daily Profile Coefficients appropriate to the GSP Group, Time Pattern Regime, Standard Settlement Configuration and Profile Class applying to the Metering System on each Settlement Day in the applicable Deemed Meter Advance Period as set out in BSCP504.

4.3.16 Where a Deemed Meter Advance has been calculated, each Supplier responsible for a metered Metering System "K" shall ensure that the relevant Non Half Hourly Data Collector responsible for such Metering System shall:

(a) determine values of Annualised Advance and Estimated Annual Consumption for each Settlement Register pursuant to paragraphs 4.3.3 to 4.3.7 (inclusive) using the value of Deemed Meter Advance determined pursuant to paragraph 4.3.15 in place of the value of Meter Advance and substituting the Meter Advance Period with the applicable Deemed Meter Advance Period as described in BSCP504; and

4.3.17 Where a Meter Advance has been calculated in accordance with BSCP504 and this has resulted in a new value of Estimated Annual Consumption which is not consistent with the last valid Estimated Annual Consumption or Annualised Advance, as the case may be, then in the circumstances set out in BSCP504, paragraph 4.3.7(b) shall not apply and the Non Half Hourly Data Collector shall apply a value of Estimated Annual Consumption which is representative of the most likely rate of generation or demand for that Metering System or, where this is not available, a value of initial Estimated Annual Consumption (EAC_KR). The Effective From Settlement Date of the value of Estimated Annual Consumption or initial Estimated Annual Consumption described above shall be the day following the end of the Meter Advance Period or Deemed Meter Advance Period, as the case may be.

4.3.18 Each Supplier shall ensure that each of its Non Half Hourly Data Collectors shall in respect of such Supplier's Unmetered Supplies for which such Non Half Hourly Data Collector is responsible and which are not subject to Equivalent Metering set the values of Estimated Annual Consumption to be those defined in the relevant Unmetered Supply Certificate and shall, in accordance with BSCP520, pass such value unadjusted to the relevant Non Half Hourly Data Aggregator responsible for such Unmetered Supply together with the Effective From Settlement Dates of such Estimated Annual Consumption.

4.3.19 Subject to paragraph 4.3.21, each Supplier which treats or intends to treat a metered Metering System "K" for which it is responsible as Long Term Vacant shall instruct (in the manner and form required by BSCP504), and ensure that, its Non Half Hourly Data Collector responsible for such metered Metering System "K" calculates a Metered Advance in accordance with the provisions of paragraph 4.3.2 or (where no relevant Metered Data is available) calculates a Deemed Metered Advance in accordance with the provisions of paragraphs 4.3.15 to 4.3.16, and an Estimated Annual Consumption (EAC_KR) for each Settlement Register (calculated according to the formulae set out in paragraph 4.3.7), and thereafter for all future calculations replace the Estimated Annual Consumption (EAC_KR) with an Estimated Annual Consumption (EAC_KR) of zero value.

4.3.20 For the purposes of paragraph 4.3.19, the Effective From Settlement Date for the use of an Estimated Annual Consumption (EAC_KR) of zero value shall be the earlier of:

(a) the date of the first visit referred to in Section S2.8.3 (a) in respect of which the appropriate notification referred to in Section S2.8.3(b) was given to the Supplier that no access to the metered Metering System "K" had been obtained by the relevant Non Half Hourly Data Collector; or

(b) if the Supplier receives notification from an owner and/or occupier of a property on which the metered Metering System "K" is situated that electricity is or will no longer be consumed on the property, the last date on which electricity is consumed on that property (which shall be treated for the purposes of this paragraph 4.3.20 as the "last consumption date"), provided that:

6. PROFILE COEFFICIENTS

6.1 Making of determinations

6.1.1 The determinations in this paragraph 6 shall be carried out by the SVAA in respect of Metering Systems and in respect of each Settlement Day for which it is required to make such determinations and which Settlement Day occurs on or after the Go-live Date.

6.1.2 The SVAA shall ensure that processes are put in place which ensure that values of Alternative Average Fraction of Yearly Consumption (AAFYC_HPR) notified to the SVAA in accordance with BSCP509 are input promptly into the Supplier Volume Allocation System.

6.2 Derivation of Settlement Register switching times for each Teleswitch Time Pattern Regime

6.2.1 The SVAA shall identify each Teleswitch Time Pattern Regime which is associated with one or more Standard Settlement Configurations of which at least one of such Standard Settlement Configurations:

(a) defines a teleswitched metering configuration; and

(b) is assigned to a Teleswitch Group.

6.2.2 For the purpose of carrying out the processes set out in this paragraph 6.2 which require the use of Teleswitch Contact Interval Data, the SVAA shall employ those Teleswitch Contact Interval Data which:

(a) have been received by the SVAA pursuant to paragraph 5.2.3; and

(b) are in respect of the UTC Days which start or end at spot times which fall within the Settlement Day then being processed.

6.2.3 If:

(a) the SVAA has not received Teleswitch Contact Interval Data pursuant to paragraph 5.2.3 in respect of one or more of the UTC Days identified pursuant to paragraph 6.2.2 by the time specified in BSCP508; or

(b) the SVAA has received the data specified in paragraph (a) by the time specified in BSCP508 but such data does not include Teleswitch Contact Interval Data in respect of each Teleswitch Group,

then the matters required to be determined under this paragraph 6.2 for the Settlement Day being processed shall be determined by reference to such default data as BSCP508 requires to be employed for such purpose.

6.2.4 In respect of each Teleswitch Time Pattern Regime identified pursuant to paragraph 6.2.1 within each Teleswitch Group, the SVAA shall employ the Teleswitch Register Rules and Teleswitch Contact Rules in respect of such Teleswitch Time Pattern Regime (which have been notified to the SVAA by each Supplier required to so notify pursuant to paragraph 5.1.1) to determine the set of Teleswitch Intervals associated with such Teleswitch Time Pattern Regime for the Settlement Day being processed as follows:

(a) by reference to the Teleswitch Contact Interval Data in respect of the Teleswitch Group being processed and the UTC Days identified pursuant to paragraph 6.2.2, the SVAA shall:

(i) determine the state of each of the Teleswitch Contacts associated with any such Teleswitch Contact Rule at the start of such Settlement Day; and

(ii) identify each following spot time of the Settlement Day at which any of such Teleswitch Contacts associated with any such Teleswitch Contact Rule change state;

(b) in respect of the spot time that is the start of Settlement Day and each spot time identified pursuant to paragraph (a), the SVAA shall, in chronological order of such spot times:

(i) determine whether each such Teleswitch Contact Rule is satisfied for the period (the "contact period") commencing with such spot time and ending at the earlier of the next following spot time identified pursuant to paragraph (a) and the end of such Settlement Day;

(ii) determine whether each such Teleswitch Register Rule is satisfied for the contact period commencing with such spot time by reference to the results of the determination pursuant to paragraph (i) for the associated Teleswitch Contact Rules;

(iii) (A) if any of such Teleswitch Register Rules is satisfied, determine that the Settlement Register associated with such Teleswitch Time Pattern Regime is recording metered consumption for the contact period; or

(B) if none of such Teleswitch Register Rules is satisfied, determine that the Settlement Register associated with such Teleswitch Time Pattern Regime is not recording metered consumption for the contact period;

(iv) if:

(A) the associated Settlement Register commences to record metered consumption at such spot time; or

(B) such spot time is the start of the Settlement Day and such Settlement Register is determined pursuant to this paragraph as recording metered consumption for the contact period commencing at such spot time,

determine that such spot time is an Unadjusted Interval Start Time but, in any other case, such spot time shall not be an Unadjusted Interval Start Time; and

(v) if:

(A) the associated Settlement Register ceases to record metered consumption at such spot time; or

(B) such spot time is the end of the Settlement Day and such Settlement Register is determined pursuant to this paragraph as recording metered consumption for the contact period ending at such spot time;

determine that such spot time is an Unadjusted Interval End Time but, in any other case, such spot time shall not be an Unadjusted Interval End Time; and

(c) the SVAA shall determine each Teleswitch Interval in such Settlement Day as a period starting at an Unadjusted Interval Start Time and ending at the next following Unadjusted Interval End Time.

6.3 Derivation of time pattern data

6.3.1 The SVAA shall carry out the process set out in this paragraph 6.3:

(a) for each Teleswitch Time Pattern Regime in respect of which Teleswitch Intervals have been determined pursuant to paragraph 6.2 in respect of such Settlement Day; and

(b) for each Time Pattern Regime in respect of which Clock Intervals have been received by the SVAA pursuant to paragraph 5.1.1 and which apply in respect of the Settlement Day then being processed.

6.3.2 The SVAA shall update each Time Pattern Regime identified pursuant to paragraph 6.3.1 to take account of the associated Teleswitch Intervals or, as the case may be, Clock Intervals that apply in respect of the Settlement Day then being processed.

6.4 Rounding of Time Pattern data

6.4.1 In respect of each Standard Settlement Configuration, the SVAA shall calculate a set of Adjusted Intervals pursuant to this paragraph 6.4, where subscript "(ai)" refers to a particular Adjusted Interval, subscript "X" refers to a Time Pattern Regime and subscript "R" refers to the combination of such a Time Pattern Regime and such Standard Settlement Configuration. The determinations set out in paragraphs 6.4.2 to 6.4.11 (inclusive) shall be carried out by the SVAA in the sequential order set out in such paragraphs. The determinations set out in paragraphs 6.4.2 to 6.4.6 (inclusive) shall be carried out in respect of a Specimen Settlement Day related to the Settlement Day then being processed and, if required pursuant to such paragraphs, the next following Specimen Settlement Day related to the Settlement Day then being processed.

6.4.2 The SVAA shall:

(a) identify all Time Pattern Regimes associated with the Standard Settlement Configuration being processed;

(b) in respect of each such Time Pattern Regime determine each Unadjusted Interval Start Time (UIST_X(ai)) as the time identified by reference to such Time Pattern Regime at which Settlement Registers associated with the Time Pattern Regime commence to record Metered Data and if such Settlement Registers are identified as recording Metered Data at the start of the Settlement Day, the start of the Settlement Day shall also be identified as an Unadjusted Interval Start Time;

(c) for each Unadjusted Interval Start Time determined in respect of a Time Pattern Regime pursuant to paragraph (b) determine an associated Unadjusted Interval End Time (UIET_X(ai)) as the earlier of:

(i) the next following time, identified by reference to such Time Pattern Regime, at which the Settlement Registers associated with the Time Pattern Regime cease to record Metered Data; and

(ii) the end of the Settlement Day; and

(d) each such period beginning at an Unadjusted Interval Start Time and ending at its associated Unadjusted Interval End Time shall be known as an "Unadjusted Interval".

6.4.3 The SVAA shall identify each spot time of the Settlement Day at which an Unadjusted Interval Start Time or an Unadjusted Interval End Time occurs for one or more of the Time Pattern Regimes associated with the Standard Settlement Configuration being processed.

6.4.4 The SVAA shall in respect of each spot time identified pursuant to paragraph 6.4.3 carry out the determinations set out in this paragraph 6.4.4 save in the case where such spot time occurs at the start of a Settlement Period or, as the case may be, at the end of the Settlement Day being processed, in which case the provisions of paragraph 6.4.6 shall apply. The determinations set out in this paragraph 6.4.4 or, as the case may require, paragraph 6.4.6 shall be carried out for each such spot time in turn in chronological order of the occurrence of all such spot times associated with the Standard Settlement Configuration being processed. For the purposes of this paragraph 6.4.4 the Settlement Period within which the spot time under consideration falls shall be denoted as Settlement Period "J":

(a) the Rounded-Up Spot Time associated with the spot time under consideration shall be determined to be the spot time at the start of the next following Settlement Period "J+1";

(b) the Rounded-Down Spot Time associated with the spot time under consideration shall be determined as the start of the Settlement Period "J";

(c) the Unrounded Duration (UD_X(ai)) of each Unadjusted Interval starting or ending at the spot time under consideration shall be determined as the time duration in minutes between its Unadjusted Interval Start Time and its associated Unadjusted Interval End Time. For the avoidance of doubt, the Unadjusted Interval End Time shall be later than the Unadjusted Interval Start Time, and this determination shall therefore result in a value of the Unrounded Duration which is a positive number of minutes;

(d) the Rounded-Up Duration (RUD_R(ai)) of each Unadjusted Interval starting or ending at the spot time under consideration shall be determined as follows:

(i) if the Unadjusted Interval ends at such spot time, the Rounded-Up Duration of such Unadjusted Interval shall be the time duration in minutes between its associated Adjusted Interval Start Time as previously determined pursuant to this paragraph 6.4.4 and the Rounded-Up Spot Time associated with such spot time. In the case in which such Adjusted Interval Start Time is later in time than such Rounded-Up Spot Time the Rounded-Up Duration shall be a negative number of minutes and, in any other case, the Rounded-Up Duration shall be a positive number of minutes; or

(ii) if the Unadjusted Interval starts at such spot time, the Rounded-Up Duration of such Unadjusted Interval shall be the time duration in minutes between the Rounded-Up Spot Time associated with the spot time under consideration and the Interim Adjusted Interval End Time determined pursuant to paragraph 6.4.5. In the case in which such Rounded-Up Spot Time is later in time than such Interim Adjusted Interval End Time the Rounded-Up Duration shall be a negative number of minutes and, in any other case, the Rounded-Up Duration shall be a positive number of minutes;

(e) the Rounded-Down Duration (RDD_R(ai)) of each Unadjusted Interval starting or ending at the spot time under consideration shall be determined as follows:

(i) if the Unadjusted Interval ends at such spot time, the Rounded-Down Duration of such Unadjusted Interval shall be the time duration in minutes between its associated Adjusted Interval Start Time as previously determined pursuant to this paragraph and the Rounded-Down Spot Time associated with such spot time. In the case in which such Adjusted Interval Start Time is later in time than such Rounded-Down Spot Time the Rounded-Down Duration shall be a negative number of minutes and, in any other case, the Rounded-Down Duration shall be a positive number of minutes; or

(ii) if the Unadjusted Interval starts at such spot time, the Rounded-Down Duration of such Unadjusted Interval shall be the time duration in minutes between the Rounded-Down Spot Time associated with the spot time under consideration and the Interim Adjusted Interval End Time determined pursuant to paragraph 6.4.5. In the case in which such Rounded-Down Spot Time is later in time than such Interim Adjusted Interval End Time the Rounded-Down Duration shall be a negative number of minutes and, in any other case, the Rounded-Down Duration shall be a positive number of minutes;

(f) for every Unadjusted Interval with an Unadjusted Interval Start Time or an Unadjusted Interval End Time which falls at such spot time, a corresponding Adjusted Interval Start Time or, as the case may be, Adjusted Interval End Time shall be determined as follows. For the purpose of making such determinations each of the following paragraphs (i) to (vii) (inclusive) shall be considered in the order set out below. In considering such paragraphs the first such paragraph encountered where the condition specified in such paragraph is satisfied for such spot time shall be employed in the determination of the Adjusted Interval Start Time or, as the case may be, Adjusted Interval End Time and all of the following such paragraphs shall be ignored:

(i) if the number of such Unadjusted Intervals for which RUD_R(ai) < 0 is less than the number of such Unadjusted Intervals for which RDD_R(ai) <0, then each corresponding Adjusted Interval Start Time and Adjusted Interval End Time shall be determined to be the start time of the next following Settlement Period "J+1";

(ii) if the number of such Unadjusted Intervals for which RUD_R(ai) < 0 is greater than the number of such Unadjusted Intervals for which RDD_R(ai) < 0, then each corresponding Adjusted Interval Start Time and Adjusted Interval End Time shall be determined to be the start time of Settlement Period "J";

(iii) if the number of such Unadjusted Intervals for which RUD_R(ai) = 0 is less than the number of such Unadjusted Intervals for which RDD_R(ai) = 0, then each corresponding Adjusted Interval Start Time and Adjusted Interval End Time shall be determined to be the start time of the next following Settlement Period "J+1";

(iv) if the number of such Unadjusted Intervals for which RUD_R(ai) = 0 is greater than the number of such Unadjusted Intervals for which RDD_R(ai) = 0, then each corresponding Adjusted Interval Start Time and Adjusted Interval End Time shall be determined to be the start time of Settlement Period "J";

(v) if Σ_(ai) (RUD_R(ai) - UD_X(ai))²< Σ_(ai) (RDD_R(ai) - UD_X(ai))²

then each corresponding Adjusted Interval Start Time and Adjusted Interval End Time shall be determined to be the start time of the next following Settlement Period "J+1";

(vi) if Σ_(ai) (RUD_R(ai) - UD_X(ai))²> Σ_(ai) (RDD_R(ai) - UD_X(ai))²

then each corresponding Adjusted Interval Start Time and Adjusted Interval End Time shall be determined to be the start time of Settlement Period "J"; or

(vii) in any other case, each corresponding Adjusted Interval Start Time and Adjusted Interval End Time shall be determined to be the start time of Settlement Period "J"; and

(g) if a determination set out in paragraph (f) above in respect of a spot time results in an Adjusted Interval End Time which falls at the same spot time as the associated Adjusted Interval Start Time falls, then such Adjusted Interval End Time shall be re-determined such that it falls at the start time of the next following Settlement Period and such re-determination shall be made before the next spot time identified pursuant to paragraph 6.4.3 is processed pursuant to this paragraph.

6.4.5 Where the SVAA is required pursuant to paragraph 6.4.4 to determine an Interim Adjusted Interval End Time in respect of an Unadjusted Interval, such Interim Adjusted Interval End Time (AIET_X(ai)) shall be determined as follows:

(a) let the Settlement Period within which the relevant UIET_X(ai) falls be identified as Settlement Period J1;

(b) if the duration of the period which begins at the start of Settlement Period J1 and ends at UIET_X(ai) is less than half the Settlement Period Duration then the Interim Adjusted Interval End Time shall be set as the start time of Settlement Period J1; and

(c) if the duration of the period which begins at the start of Settlement Period J1 and ends at UIET_X(ai) is equal to half the Settlement Period Duration and the start time of Settlement Period J1 is an exact hour then the Interim Adjusted Interval End Time shall be set as the start time of Settlement Period J1;

but in any other case the Interim Adjusted Interval End Time shall be set as the start time of the next following Settlement Period (J1+1).

6.4.6 The provisions of this paragraph 6.4.6 apply in the case where a spot time identified pursuant to paragraph 6.4.4 occurs at the start of a Settlement Period or, as the case may be, the end of the Settlement Day being processed. In such case then:

(a) for any Unadjusted Interval Start Time which occurs at such spot time its associated Adjusted Interval Start Time shall be determined to be that same spot time; and

(b) for any Unadjusted Interval End Time which occurs at such spot time its associated Adjusted Interval End Time shall be determined to be that same spot time.

6.4.7 If the Time Pattern Regime is classified as being in "local time" then the Adjusted Interval Start Times and Adjusted Interval End Times associated with such Time Pattern Regime and Standard Settlement Configuration determined pursuant to paragraphs 6.4.2 to 6.4.6 (inclusive) shall be construed as being in UK local time on such Settlement Day "D" or, as the case may be, the next following Settlement Day "D + 1". For the purposes of this paragraph 6.4.7 and paragraph 6.4.9 such next following Settlement Day "D + 1" is a Replica Settlement Day related to Settlement Day "D". The following provisions shall also apply if the Settlement Day "D" then being processed is a Settlement Day on which there is a Clock Change:

(a) if there is an additional (repeated) hour or hours in such Settlement Day "D" as compared with a related Specimen Settlement Day, then any Adjusted Interval Start Time and Adjusted Interval End Time which would as a result of this operation occur at an hour spot time or, as the case may be, half hour spot time that occurs more than once in such Settlement Day shall be construed so that such Adjusted Interval Start Time or, as the case may be, Adjusted Interval End Time occurs at the first occurrence of the hour spot time or, as the case may be, half hour spot time in such Settlement Day "D"; or

(b) if there is an hour or hours fewer in such Settlement Day "D" as compared with a related Specimen Settlement Day, then each Adjusted Interval Start Time and Adjusted Interval End Time which would, if this operation were done in respect of such Specimen Settlement Day, occur at a spot time on such Specimen Settlement Day and which spot time does not exist on the Settlement Day "D", shall be adjusted so that it occurs at the first following spot time on such Settlement Day "D" which does exist.

6.4.8 If the Time Pattern Regime is classified as being in "GMT" as distinct from "local time" then the Adjusted Interval Start Times and Adjusted Interval End Times determined pursuant to paragraphs 6.4.2 to 6.4.6 (inclusive) shall be construed as being in Greenwich Mean Time. Such times shall then be converted to the corresponding UK local time on the Settlement Day "D" then being processed, taking due account of any Clock Change applying to UK local time on such Settlement Day "D". For the avoidance of doubt such adjustments may result in Adjusted Interval Start Times or Adjusted Interval End Times which fall in the next following Settlement Day "D + 1". For the purposes of this paragraph 6.4.8 and paragraph 6.4.9 such Settlement Day "D + 1" is a Replica Settlement Day related to Settlement Day "D".

6.4.9 If any Adjusted Interval Start Time or Adjusted Interval End Time determined pursuant to paragraphs 6.4.2 to 6.4.8 (inclusive) occurs at a spot time in Settlement Day "D+1", such Settlement Day being that next following the Settlement Day, "D", on which the associated Unadjusted Interval Start Time or, as the case may be, Unadjusted Interval End Time falls, such Adjusted Interval Start Time or, as the case may be, Adjusted Interval End Time shall be modified so that it occurs on Settlement Day "D" at the same spot time as it had, before such modification, occurred on Settlement Day "D+1".

6.4.10 An Adjusted Interval shall be determined as a period of time starting at and including an Adjusted Interval Start Time and ending on but not including the associated Adjusted Interval End Time save in the case where a modification has been made pursuant to paragraph 6.4.9. In such case there shall be two Adjusted Intervals as follows:

(a) a period of time starting at and including the Adjusted Interval Start Time and ending on but not including the end of the Settlement Day "D"; and

(b) a period of time starting at and including the start time of Settlement Day "D" and ending on but not including the Adjusted Interval End Time associated with such Adjusted Interval Start Time.

6.4.11 In respect of each combination of Time Pattern Regime and Standard Settlement Configuration "R", the SVAA shall determine a Period Time Pattern State Indicator (Q_Rj) for each Settlement Period as follows:

(a) if the start time of such Settlement Period falls at an Adjusted Interval Start Time or any time within an Adjusted Interval associated with such Time Pattern Regime determined pursuant to this paragraph 6.4 then:

Q_Rj = 1; and

(b) in any other case Q_Rj = 0.

6.5 Evaluation of Basic Period Profile Coefficients for each Time Pattern Regime

6.5.1 In respect of each GSP Group for each Settlement Day, the SVAA shall determine the Noon Effective Temperature (NET_H) as:

NET_H = 0.57T_HT + 0.28T_HT-1 + 0.15T_HT-2

where T_HT,T_HT-1and T_HT-2are the Grid Supply Point Group Measured Temperatures procured from the Temperature Provider pursuant to paragraph 5.2.2 for GSP Group "H" in respect of Settlement Day "D", "D-1" and "D-2" respectively and where Settlement Day "D" is the then current Settlement Day, Settlement Day "D-1" is the immediately preceding Settlement Day and Settlement Day "D-2" is the Settlement Day immediately preceding that designated as "D‑1".

6.5.2 In respect of each Settlement Day, the SVAA shall determine the Sunset Variable (S) from the Time of Sunset data provided pursuant to paragraph 5.1.6 as follows:

(a) the Sunset Time (SUNT) in respect of the Settlement Day is the time duration in minutes from the start of the Settlement Day to the time of sunset determined with reference to the Time of Sunset data;

(b) SIX_PM is the time duration in minutes from the start of the Settlement Day to 1800 hours Greenwich Mean Time on that Settlement Day; and

S = SUNT - SIX_PM.

6.5.3 In respect of each Profile "Q" of each Profile Class "P" within a GSP Group "H", the SVAA shall determine a set of Basic Period Profile Coefficients (P_HQj) as set out in paragraphs (a) to (f) (inclusive):

(a) for the purposes of this paragraph the values of MRC_Q(aa)(nn)jare the values of the Matrix of Regression Coefficients supplied for the time being and from time to time by the Profile Administrator (or by BSCCo where BSCCo provides the Profile Administration Services in accordance with Section C9) where the subscript "(nn)" represents individual values of MRC_Q(aa)(nn)j and such subscript takes values between 0 and 7 inclusive;

(b) for the avoidance of doubt and for the purpose of this paragraph 6.5 the subscript "j" represents Settlement Periods of the Settlement Day. In both of the cases (i) and (ii), the number of Settlement Periods in respect of which values of MRC_Q(aa)(nn)j are supplied by the Profile Administrator (or BSCCo where BSCCo provides the Profile Administration Services in accordance with Section C9) may not correspond to the number of Settlement Periods in the Settlement Day under consideration. In such cases the values of MRC_Q(aa)(nn)j supplied shall be employed in the determination of values of Basic Period Profile Coefficient (P_HQj) pursuant to this paragraph 6.5. Such values of Basic Period Profile Coefficient shall subsequently be allocated to specific Settlement Periods of the Settlement Day under consideration:

(i) in the case of a Baseload Profile and when there is Clock Change on the Settlement Day under consideration only, such allocation shall be made pursuant to paragraph 6.5.4; or

(ii) in the case of a Profile associated with switched load such allocation shall be made pursuant to paragraph 6.6. For the avoidance of doubt, in this case (ii) such allocation may not result in a value of Basic Period Profile Coefficient for every Settlement Period in the Settlement Day;

(c) the Regression Coefficients (RC_HQ(nn)j) shall be determined as equal to the value of those coefficients MRC_Q(aa)(nn)j which apply in respect of the relevant Profile "Q" and the Analysis Class "(aa)" which is identified by the data procured from the Profile Administrator pursuant to paragraph 5.1.4 as being relevant to the given Settlement Day and GSP Group;

(d) for the avoidance of doubt, a value of RC_HQ(nn)j shall not be determined pursuant to paragraph (c) and shall not be set to zero in respect of any Settlement Period "j" for which a value of MRC_Q(aa)(nn)j is not defined. This paragraph (d) shall also apply mutatis mutandis in respect of the determinations of values of Estimated Regional Average Demand Per Customer (y_HQj) and Basic Period Profile Coefficient pursuant to paragraphs (e) and (f);

(e) the Estimated Regional Average Demand Per Customer (y_HQj) shall be determined as:

y_HQj = RC_HQ0j+(RC_HQ1j * Mon_T )+ (RC_HQ2j * Wed_T)+ (RC_HQ3j * Thu_T)+ (RC_HQ4j * Fri_T)+ (RC_HQ5j * NET_H )+ (RC_HQ6j* S) +(RC_HQ7j * (S)²);

where Mon_T = 1 if Settlement Day "D" is a Monday or in any other case Mon_T= 0; and

Wed_T, Thu_T and Fri_T are determined mutatis mutandis to Mon_T but as if references to Settlement Day "D" were to a Wednesday, a Thursday or, as the case may be, a Friday; and

(f) in respect of each value of Estimated Regional Demand Per Customer determined pursuant to paragraph (e) a value of Basic Period Profile Coefficient (P_HQj) shall be determined as:

P_HQj= max(y_HQj / (GAAC_HQ * 2000), 0)

where GAAC_HQ is the Group Average Annual Consumption procured, for the time being and from time to time, from the Profile Administrator (or from BSCCo where BSCCo the Profile Administration Services in accordance with Section C9) pursuant to paragraph 5.1.4.

6.5.4 If the Settlement Day "D" is a Settlement Day on which there is a Clock Change then each set of Basic Period Profile Coefficients corresponding to a Profile "Q" determined pursuant to paragraph 6.5.3 shall be modified as follows, save where the Profile "Q" is a switched load Profile in which case the relevant set of Basic Period Profile Coefficients shall not be modified. In the circumstances described in this paragraph, the value of subscript "j" for each value of Basic Period Profile Coefficient determined pursuant to paragraph 6.5.3 and which is to be modified pursuant to this paragraph shall, prior to such modification only, denote the Settlement Period "j" of the related Specimen Settlement Day to which such value corresponds. The terms "lost", "fewer" and "additional" when applied to hours in the Settlement Day "D" on which there is a Clock Change shall be construed as a comparison with such Specimen Settlement Day:

(a) if there is an hour or hours fewer in the Settlement Day "D" then the relevant Basic Period Profile Coefficients in respect of the Settlement Periods corresponding to the hours lost on such Settlement Day "D" shall be deleted and each such value of the resulting reduced set of Basic Period Profile Coefficients shall be re-labelled with new values of subscript "j" in the same order as the original set so that each value of the set corresponds to a Settlement Period that exists on such Settlement Day "D" and each such Settlement Period is associated with one value of the Basic Period Profile Coefficient set;

(b) if there is an additional (repeated) hour or hours in the Settlement Day "D" then the relevant Basic Period Profile Coefficients in respect of the second occurrence of any hour or hours shall be determined by linear interpolation pursuant to paragraph 3.6 of Annex X-2 save in the circumstances described in paragraph (c) in which case the determination described there shall be performed. The resulting increased set of Basic Period Profile Coefficients shall be re-labelled with new values of subscript "j" in the same order as the original set with the insertion of the additional values of Basic Period Profile Coefficient at the appropriate point in the sequence of values to correspond to the second occurrence of any hour or hours so that each value of the set corresponds to a Settlement Period that exists on such Settlement Day "D" and each such Settlement Period is associated with one value of the Basic Period Profile Coefficient set. For this purpose each Settlement Period (including those in respect of the second occurrence of any hour or hours) on such Settlement Day "D" starting from the Settlement Period immediately preceding the second occurrence of any hour or hours to the Settlement Period immediately following such second occurrence of any hour or hours shall be labelled in chronological order with ascending equally spaced values of z_n, starting from z₀. For the purposes of paragraph 3.6 of Annex X-2:

x₀shall take the value of z₀;

x₁shall take the value of z_Nwhere N is the highest value of n;

each ascending value of x_i shall take the next ascending value of z_nstarting with z₁and ending with z_N-1, eachcorresponding to one of the Settlement Periods for which a value of Basic Period Profile Coefficient is required to be determined, and the related spot value y_ishall be the required value of such Basic Period Profile Coefficient;

y₀ shall take the value of the Basic Period Profile Coefficient for the Settlement Period labelled z₀; and

y₁ shall take the value of the Basic Period Profile Coefficient for the Settlement Period labelled z_N; or

(c) if there is an additional (repeated) hour or hours in the Settlement Day "D" and the Clock Change causing such additional hour(s) takes place at the end of the Settlement Day "D" then the relevant Basic Period Profile Coefficients in respect of the second occurrence of any hour or hours shall be determined as follows. The resulting increased set of Basic Period Profile Coefficients shall be re-labelled with new values of subscript "j" in the same manner as described in paragraph (b). For the purposes of this paragraph (c) each Settlement Period (including those in respect of the second occurrence of any hour or hours) on such Settlement Day "D" starting from the Settlement Period which immediately precedes the Settlement Period which itself immediately precedes the second occurrence of any hour or hours to the last Settlement Period of the Settlement Day "D" shall be labelled in chronological order with ascending equally spaced values of z_n; starting from z₀ . For the purposes of paragraph 3.6 of Annex X-2:

x₀shall take the value of z₀;

x₁shall take the value of z₁;

each ascending value of x_i shall take the next ascending value of z_nstarting with z₂ and ending with z_Nwhere N is the highest value of n, eachcorresponding to one of the Settlement Periods for which a value of Basic Period Profile Coefficient is required to be determined, and the related spot value y_ishall be the required value of such Basic Period Profile Coefficient;

y₀ shall take the value of the Basic Period Profile Coefficient for the Settlement Period labelled z₀; y₁ shall take the value of the Basic Period Profile Coefficient for the Settlement Period labelled z₁; and

y_i = max( y₁ + (y₁- y₀) * (i-1), 0).

6.6.7 If the set of Switched Load State Indicators (SQ_Cj) associated with the Standard Settlement Configuration and Settlement Day then being processed have values which satisfy the condition that:

Σ_j SQ_Cj > 47

then the SVAA shall determine a Modified Switched Load State Indicator (SQNEW_Cj) for each Settlement Period of such Settlement Day as follows:

(a) for the purposes of this paragraph the SVAA shall label each such Settlement Period in the chronological order of such Settlement Periods for which the condition that SQ_Cj= 1 is true with ascending integer values of "J" commencing with a value of J = 1 but shall not so label any Settlement Period for which such condition is not true;

(b) for each Settlement Period "j" which is labelled with a value of "J" pursuant to paragraph (a) and where such value is greater than forty-seven, then:

SQNEW_Cj = SQ_Cj

6.6.11 The SVAA shall determine the On Period Duration (OD_C) as:

OD_C = Σ_jSQNEW_Cj

6.6.12 The SVAA shall identify the Longest Off Period as the longest period of contiguous Settlement Periods in the Settlement Day being processed for which the condition that SQNEW_Cj = 0 for each such Settlement Period "j" is true, provided that:

(a) if for both the first Settlement Period and the last Settlement Period of the Settlement Day being processed the condition SQNEW_Cj = 0 is true for both such Settlement Periods, then:

(i) if for every Settlement Period of such Settlement Day the condition SQNEW_Cj = 0 is true the SVAA shall not determine Normal Register Profile Coefficients or Low Register Coefficients pursuant to this paragraph for the combination of Profile Class, Standard Settlement Configuration, GSP Group and Settlement Day then being processed; or

(ii) in any other case, for the purposes of identifying the Longest Off Period, the two periods identified as follows shall be considered as a single period of contiguous Settlement Periods in such Settlement Day for which the condition that SQNEW_Cj = 0 for each such Settlement Period "j" is true:

(B) the period commencing at the start of the last Settlement Period "j" of such Settlement Day for which SQNEW_Cj =0 and SQNEW_Cj-1 = 1 and ending at the end of such Settlement Day;

(b) if there is no Settlement Period "j" of such Settlement Day for which SQNEW_Cj = 0, the SVAA shall identify that there is no Longest Off Period and shall perform the actions specified in paragraph 6.6.14 (a); and

(c) if there are two or more separate periods of equal duration each of which would, if that other period or, as the case may be, those other periods of equal duration did not exist, satisfy the condition to be the Longest Off Period pursuant to this paragraph, the SVAA shall identify that there is no unique Longest Off Period and shall identify the Longest On Period pursuant to paragraph 6.6.13.

6.6.13 In the case in which paragraph 6.6.12(c) applies, the SVAA shall identify the Longest On Period as the longest period of contiguous Settlement Periods in the Settlement Day being processed for which the condition that SQNEW_Cj = 1 for each such Settlement Period "j" is true, provided that if there are two or more separate periods of equal duration each of which would, if that other period or, as the case may be, those other periods of equal duration did not exist, satisfy the condition to be the Longest On Period pursuant to this paragraph, the SVAA shall identify the last such period in chronological order of such periods as the Longest On Period.

6.6.14 In respect of each Standard Settlement Configuration "C" identified pursuant to paragraph 6.6.1, the SVAA shall label those Settlement Periods of the Settlement Day for which SQNEW_Cj has a value of 1 as follows:

(a) if the SVAA has identified pursuant to paragraph 6.6.12(b) that there is no Longest Off Period, the SVAA shall label the first Settlement Period of such Settlement Day as J=1 and then shall label the subsequent Settlement Periods in that Settlement Day in ascending chronological order with ascending integer values of J so that each Settlement Period of the Settlement Day for which SQNEW_Cj = 1 is labelled with a unique value J;

(b) if the Longest Off Period identified pursuant to paragraph 6.6.12 comprises the two periods specified in paragraph 6.6.12(a)(ii), the SVAA shall label the first Settlement Period of the Settlement Day for which SQNEW_Cj = 1 as J=1 and then shall label the subsequent Settlement Periods in that Settlement Day for which SQNEW_Cj = 1 in ascending chronological order with ascending integer values of J so that each Settlement Period of the Settlement Day for which SQNEW_Cj = 1 is labelled with a unique value J;

1.4.2 Subject to paragraphs 1.4.6, if by the time the SAA is to carry out the Interim Information Settlement Run complete and valid data have not been received by the SAA in accordance with paragraph 1.3 in respect of the relevant Settlement Day, then:

(a) where the invalid or missing data are not, in the SAA's opinion, a significant proportion of the data required to carry out the Interim Information Settlement Run in respect of that Settlement Day, the SAA shall inform BSCCo and shall input default data (in accordance with BSCP01) for the purposes of producing the Interim Information Settlement Run;

(b) where the invalid or missing data are, in the SAA's opinion, a significant proportion of the data required to carry out the Interim Information Settlement Run in respect of that Settlement Day:

(i) if the SAA considers that the invalid data will be corrected and re-submitted or the missing data will be submitted by the end of the next following Business Day, the SAA shall inform BSCCo and shall delay the Interim Information Settlement Run until such data is corrected and re-submitted or submitted (as the case may be);

(ii) if:

(2) in the case of paragraph (i) above, the SAA does not receive such data by the end of the next following Business Day,

the SAA shall inform BSCCo and BSCCo shall determine whether default data should be substituted for the invalid or missing data (in accordance with BSCP01) for the purposes of producing the Interim Information Settlement Run or whether production of the Interim Information Settlement Run should be delayed for a specified period in order that complete and valid data may be obtained by the SAA;

(c) the SAA shall continue to request the person responsible for submitting such data to resubmit and/or correct the data.

1.4.3 For the purposes of paragraph 1.4.2, "significant" shall be interpreted having regard to the purpose for which the Interim Information Settlement Run is produced, namely to provide a reasonably accurate reflection of what is expected to be contained in the Initial Settlement Run in respect of the relevant Settlement Day (taking into account the fact that the Interim Information Settlement Run does not include any data in respect of Supplier Volume Allocation).

1.4.4 Paragraph 1.4.2 shall not apply to data in respect of Supplier Volume Allocation.

1.4.5 Subject to paragraphs 1.4.6 and 1.4.7, if at any time from the Business Day prior to the day on which the SAA is to carry out the Initial Settlement Run the SAA forms the view that it does not expect to receive substantially complete and valid data in accordance with paragraph 1.3 in respect of the relevant Settlement Day in time to carry out such Settlement Run in accordance with the Settlement Calendar, then:

(a) the SAA shall inform BSCCo; and

(b) BSCCo shall determine whether default data should be substituted for the invalid or missing data (in accordance with BSCP01) for the purposes of producing the Initial Settlement Run or whether production of the Initial Settlement Run should be delayed for a specified period in order that complete and valid data may be obtained by the SAA.

1.4.6 Where and for so long as any of paragraphs (a), (b), (c) or (d) of Section K5.4.6 applies in respect of an Interconnector, all BM Unit Metered Volumes for the Interconnector BM Units of each Interconnector User for that Interconnector (whether or not any such volumes are submitted under paragraph 1.3.5) shall be set to zero.

1.5.2 The Market Index Definition Statement shall contain the following:

(a) nomination of the particular entity or entities (each a "Market Index Data Provider") which shall be responsible for making available Market Index Data in respect of each Settlement Period for the purposes of paragraph 4.4;

(b) full definition of the particular data and methodology to be used by the Market Index Data Provider(s) in determining the Market Index Data for each Settlement Period (including, where applicable, identification of the particular products, period of trading and any relevant weighting to be applied); and

(c) definition and determination, for the purposes of paragraph 4.3A.1, of a minimum liquidity requirement per Settlement Period (expressed in MWh) in respect of each Market Index Data Provider individually (in each case, an "Individual Liquidity Threshold") which, for the avoidance of doubt, may be zero in any case and may vary in any case according to the Settlement Period and/or the Settlement Day or otherwise.

1.5.3 The principles referred to in paragraph 1.5.1 are:

(a) the Market Index Data is to be used in Settlement to calculate a price (expressed in £/MWh) in respect of each Settlement Period (in accordance with paragraphs 4.4.2(b) and 4.4.3(b)) which reflects the price of wholesale electricity in Great Britain for delivery in respect of that Settlement Period in the short term market, in circumstances where the levels of liquidity in the market during that period and in respect thereof are not exceptionally low;

(b) for the purposes of paragraph 1.5.3(a):

(i) 'reflects' means 'provides a reasonable reflection of';

(ii) references to the 'market' are to the market in general and not to any particular market or particular type of market (organised or otherwise);

(iii) 'short term' is to be taken as meaning, in respect of a Settlement Period, a period of hours or days immediately prior to the Submission Deadline but in any event no more than three Business Days prior to the Submission Deadline;

(iv) 'delivery' refers to transactions where the intended method of performance is by way of submission of Energy Contract Volume Notifications or Metered Volume Reallocation Notifications; and

(v) the price of wholesale electricity for delivery in respect of a Settlement Period may include the price for a block of Settlement Periods which include that Settlement Period, provided the block comprises no more than twenty four hours in total.

1.5.4 The Panel shall review the Market Index Definition Statement:

(a) from time to time, and in any event at least once every twelve months; and/or

(b) if any change in circumstances occurs or is expected to occur which affects or is likely to affect in any material way the provision of Market Index Data by a Market Index Data Provider; and/or

(c) where necessary in order to give full and timely effect to any relevant Approved Modification by the Implementation Date for that Approved Modification,

by reference to the principles set out in paragraph 1.5.3, and shall make such revisions to the Market Index Definition Statement as may be determined by it and approved by the Authority following such review.

1.5.5 In establishing and reviewing the Market Index Definition Statement, the Panel shall:

(a) investigate what data exists and is available in respect of the market referred to in paragraph 1.5.3;

(b) consult with Parties and other interested parties in connection with the Market Index Definition Statement and have due regard to any representations made and not withdrawn during such consultations;

1.5.6 Where a revised Market Index Definition Statement is approved by the Authority:

(a) such revised Market Index Definition Statement shall be effective from such date as the Panel shall determine with the approval of the Authority (and shall apply in respect of Settlement Days from that date); and

(b) the Panel Secretary shall give notice of such date to each Party, the SAA and the BMRA.

1.5.7 BSCCo shall ensure that a copy of the Market Index Definition Statement (as revised from time to time) is:

(a) sent to each Party, the SAA and the BMRA; and

(b) published, and made available on request to any person.

1.5.8 For the purposes of this paragraph 1.5, the "commencement date" is the Settlement Day with effect from which, pursuant to paragraphs 4.4.2(b) and 4.4.3(b), Market Index Price and Market Index Volume data is first to be applied in determining energy imbalance prices for the purposes of Settlement.

1.6 Provision of Market Index Data

1.6.1 The Market Index Data to be provided by each Market Index Data Provider in respect of each Settlement Period shall comprise for that Settlement Period:

(a) a volume expressed in MWh; and

(b) a price expressed in £/MWh,

in each case determined in accordance with the Market Index Definition Statement.

1.6.2 For each Settlement Period, each Market Index Data Provider will determine its Market Index Data in accordance with the Market Index Definition Statement and submit such data to:

(a) the BMRA, such as to be received by the BMRA no later than the end of the Settlement Period to which the data pertains;

(b) the SAA and BSCCo, by way of daily report containing the data separately for each Settlement Period in the Settlement Day to which the data pertains and such as to be received by the SAA and BSCCo no later than the end of the Business Day next following the relevant Settlement Day.

1.6.3 Without prejudice to paragraph 4.3A.1, if in respect of a Settlement Period and a Market Index Data Provider the Individual Liquidity Threshold for that Market Index Data Provider (as determined in accordance with the Market Index Definition Statement) exceeds the Market Index Volume which would otherwise have been submitted by it, the Market Index Data Provider will instead submit a Market Index Volume with a value of zero.

1.6.4 Without prejudice to any rights or remedies available to BSCCo under the Market Index Data Provider Contract, if a Market Index Data Provider is unable to determine and/or submit its Market Index Data or to do so within the timescales set out in paragraph 1.6.2, it will:

(a) inform BSCCo, the BMRA and the SAA immediately, giving details of the cause of such inability, when it expects to be able to determine and submit such data and the Settlement Periods likely to be affected;

(b) endeavour to determine and submit such data as soon as it reasonably can, in which case such data shall be taken into account in the next Settlement Run for the relevant Settlement Day after such submission.

1.6.5 In respect of any Settlement Day for which the SAA does not receive Market Index Data from a Market Index Data Provider:

(a) the provisions of paragraph 1.4, other than paragraph 1.4.1, shall not apply (and the default rules under paragraph 4.3A.1 shall apply instead); and

(b) the SAA shall inform BSCCo.

1.6.6 Without prejudice to Section W1.3.2(c)(iv), where, following the submission by a Market Index Data Provider of Market Index Data in respect of a Settlement Period in accordance with paragraph 1.6.2, a change is made to any underlying data item of the Market Index Data Provider such that the Market Index Data so submitted is no longer the data which would have been submitted by it in respect of that Settlement Period in accordance with the Market Index Definition Statement:

(a) the Market Index Data Provider will promptly:

(i) inform BSCCo of such change and its effect on the Market Index Data;

(ii) resubmit the Market Index Data for the relevant Settlement Period(s) taking account of such change; and

(b) where the Market Index Data Provider resubmits any Market Index Data as provided in paragraph (a)(ii) above, such revised Market Index Data shall be taken into account in the next Settlement Run for the relevant Settlement Day after such submission.

1.6.7 It shall be the responsibility of BSCCo to enter into a contract with each person nominated as a Market Index Data Provider for the provision of Market Index Data in accordance with this paragraph 1.6 and for these purposes:

(a) a Market Index Data Provider shall not be considered to be a 'BSC Agent' under the Code;

(b) notwithstanding paragraph 1.6.7(a), the provisions of Sections E2.1.2, E2.2.4, E2.2.5, E2.2.6, E2.4, E2.6 and Section E3 shall apply to each Market Index Data Provider Contract and to the provision of Market Index Data as if references to BSC Agent included the Market Index Data Provider and references to a BSC Agent Contract included the Market Index Data Provider Contract subject to the following:

(i) provisions in Section E2 and E3 relating to the selection and appointment of BSC Agents shall not apply (the selection and appointment of Market Index Data Provider(s) being prescribed in the Market Index Definition Statement);

(ii) references in Section E2 and E3 to BSC Service Descriptions shall be disregarded; and

(iii) the provisions of Section E3.2 apply to a Market Index Data Provider in its capacity as such and not in any other capacity which it may have under the Code.

(a) such Party shall have no rights, benefits, obligations or liability in its capacity as Market Index Data Provider to or against any other Party under the Code, but without prejudice to its rights and obligations:

(i) as Market Index Data Provider under its Market Index Data Provider Contract; and

(ii) in any other capacity under the Code;

(b) references to Party or Parties in the Code shall be construed as excluding any Market Index Data Provider (which is a Party) in its capacity as a Market Index Data Provider (but as including such person in any other capacity it may have under the Code);

(c) the provision of Market Index Data shall be made pursuant to the Market Index Data Provider Contract and not pursuant to the Code and, accordingly, such data shall not be considered relevant party data for the purposes of Section H4.6;

(d) the provision, disclosure and use of any market data relating to a Party which is used in or in connection with the determination of Market Index Data by a Market Index Data Provider shall not be considered or construed as being made pursuant to any provision of the Code.

1.6.9 Notwithstanding paragraph 1.6.7(a):

(a) Section H4.6 shall apply to Market Index Data Providers as if references to BSC Agents included Market Index Data Providers and references to BSC Agent Contracts included Market Index Data Provider Contracts;

1.7 Single imbalance price

1.7.1 Where, for the purposes of any Contingency Provisions, a single imbalance price is to apply in relation to any Settlement Period:

(a) paragraph 1.7.1A or paragraph 1.7.2 shall apply;

(b) the provisions of paragraphs 4.4.2 and 4.4.3 in relation to the determination of System Buy Price and System Sell Price shall not apply; and

(c) for all purposes of the Code, the System Buy Price and the System Sell Price for that Settlement Period shall be the same and shall have the value established in accordance with paragraphs 1.7.1A or (as applicable) 1.7.2 (and shall be deemed to have been determined under paragraph 4.4).

1.7.1A Where a single imbalance price is to apply in relation to a relevant Settlement Period for the purposes of Section G3 or Section G4, the Panel shall, subject to the approval of the Authority, determine that single imbalance price in accordance with this paragraph 1.7.1A or, where the Panel, in its opinion, considers this provision unsuitable, in accordance with paragraph 1.7.2. For the purposes of this paragraph 1.7.1A the single imbalance price shall be:

(a) subject to paragraphs (b) and (d), the mean of the System Sell Price and the System Buy Price calculated respectively for each set of corresponding Settlement Periods in the thirty whole Settlement Days immediately preceding the Settlement Day on which the System Restoration Period (as defined in Section G3.1.2(d)) or Security Period (as defined in the Fuel Security Code) commenced;

(b) the NETSO shall determine that certain Settlement Periods within the Settlement Days identified under paragraph (a) be excluded from the single imbalance price calculation if those Settlement Periods occur within a System Restoration Period or Security Period or if during those Settlement Periods emergency instructions were issued under the Grid Code;

(c) where paragraph (b) applies, the Panel shall use the System Sell Price and the System Buy Price from additional Settlement Periods to achieve a mean of 30 System Sell Prices and System Buy Prices for each corresponding Settlement Period. Such additional Settlement Periods shall be those corresponding Settlement Periods in the Settlement Day immediately preceding the Settlement Days identified in paragraph (a);

(d) where a Clock Change Day occurs in the thirty Settlement Days immediately prior to the System Restoration Period or Security Period that Settlement Day is to be excluded for the purposes of this paragraph 1.7.1A and a further Settlement Day in accordance with paragraph (e) is to be selected;

(e) where paragraph (d) applies, the Panel shall use the System Sell Price and the System Buy Price from an additional Settlement Day (immediately prior to the thirty Settlement Days referred to in paragraph (a)) to achieve a mean of 30 System Sell Prices and System Buy Prices for each corresponding Settlement Period;

(f) where a Clock Change Day occurs in a System Restoration Period or Security Period:

(i) if the Clock Change Day is short (forty six Settlement Periods) the third and fourth Settlement Periods (and thus the single imbalance price calculated in accordance with this paragraph 1.7.1A for the third and fourth Settlement Periods) shall be ignored for that Clock Change Day; and

(ii) where the Clock Change Day is long (fifty Settlement Periods) the single imbalance price calculated in accordance with this paragraph 1.7.1A for the third and fourth Settlement Periods shall be repeated for the fifth and sixth Settlement Periods of that Clock Change Day. The single imbalance price for the remaining Settlement Periods for that Clock Change Day will be the single imbalance price calculated in accordance with this paragraph 1.7.1A but (other than for the first and second Settlement Periods) for two Settlement Periods earlier (that is to say the single imbalance price calculated for Settlement Period five will apply to Settlement Period seven on a long Clock Change Day, the single imbalance price calculated for Settlement Period six will apply to Settlement Period eight and so on); and

(g) in this paragraph 1.7.1A, save for paragraph (f), "corresponding" means corresponding in sequence (that is to say, the first Settlement Period of a Settlement Day corresponds to the first Settlement Period of another Settlement Day and so on).

1.7.2 Subject to paragraph 1.7.1A, where this paragraph applies, the Panel shall determine, in its opinion, subject to the approval of the Authority, what is or would have been the market price for bulk electricity in the relevant Settlement Period; and for these purposes:

(a) bulk electricity means electricity traded under contracts which may be performed by the notification of Energy Contract Volumes in accordance with Section P;

(b) the Panel may make reference for the purposes of its determination to reported prices and price indices for bulk electricity for any Settlement Period (on any day) which the Panel considers to be comparable, and to equivalent prices and indices relating to periods prior to the Go-Live Date (making appropriate adjustments in respect of any differing treatment of transmission losses and related matters).

1.7.3 The Panel shall wherever practicable make its determination in time for such determinations to be taken into account in the Initial Settlement Run in relation to the relevant Settlement Period.

1.7.4 BSCCo shall promptly notify the Panel's determination to the SAA and to each Party.

1.8 De Minimis Acceptance Threshold

1.8.1 For the purposes of the Code the "De Minimis Acceptance Threshold" (DMAT) shall be 1 MWh or such other amount (in MWh) as the Panel may from time to time determine, after consultation with, the NETSO and Trading Parties and subject to the approval of the Authority, as the de-minimis level below which it would be appropriate to disregard accepted Bids and accepted Offers from the calculation of the energy imbalance prices.

1.8.2 Where a revised value for the De Minimis Acceptance Threshold is approved by the Authority:

(a) such revised value shall be effective from such date as the Panel shall determine with the approval of the Authority, not being less than twenty Business Days after the date of the Panel’s determination;

(b) the Panel Secretary shall promptly give notice of the revised value and its effective date to each Party, the SAA and the BMRA and shall copy such notice to the Authority;

1.16.4 BSCCo shall ensure that a copy of the Supplier Compensation Reference Price Methodology Document Methodology Document (as revised from time to time) is sent to each Party, the SAA and the BMRA.

2. ALLOCATION OF TRANSMISSION LOSSES

2.1 Delivering and Offtaking Trading Units

2.1.1 For the purpose of scaling for transmission losses, in respect of each Settlement Period,

(a) a Trading Unit is a "delivering" Trading Unit when Σ_iQM_ij > 0 and

(b) a Trading Unit is an "offtaking" Trading Unit when Σ_iQM_ij ≤ 0

where Σ_i represents the sum over all BM Units belonging to that Trading Unit.

2.2 Transmission Loss Factors

2.2.1 For the purposes of the Code, the Transmission Loss Factor and factor α shall be as follows:

(a) for each BM Unit, TLF_ij shall be determined in accordance with Annex T-2, and

(b) α = 0.45.

2.3 Determination of the Transmission Loss Multipliers

2.3.1 In respect of each Settlement Period, for each BM Unit other than Interconnector BM Units and Secondary BM Units, the Transmission Loss Multiplier shall be calculated as follows:

(a) for all BM Units belonging to Trading Units which in the Settlement Period are delivering Trading Units:

TLM_ij = 1 + TLF_ij + TLMO⁺_j

(b) for all BM Units belonging to Trading Units which in the Settlement Period are offtaking Trading Units:

TLM_ij = 1 + TLF_ij + TLMO^-_j

where:

TLMO⁺_j = – {α(Σ⁺QM_ij + Σ^-QM_ij) + Σ⁺_(non-I) (QM_ij * TLF_ij)} / Σ⁺_(non-I) QM_ij;

TLMO^-_j = {(α–1)(Σ⁺QM_ij + Σ^-QM_ij) – Σ^-_(non-I) (QM_ij * TLF_ij)} / Σ^-_(non-I) QM_ij;

Σ⁺ represents the sum over all BM Units other than Secondary BM Units belonging to Trading Units that are delivering Trading Units in the Settlement Period;

Σ^- represents the sum over all BM Units other than Secondary BM Units belonging to Trading Units that are offtaking Trading Units in the Settlement Period;

Σ⁺_(non-I)represents the sum over all BM Units other than Interconnector BM Units and Secondary BM Units belonging to Trading Units that are delivering Trading Units in the Settlement Period; and

Σ^-_(non-I)represents the sum over all BM Units other than Interconnector BM Units and Secondary BM Units belonging to Trading Units that are offtaking Trading Units in the Settlement Period.

2.3.2 In respect of each Settlement Period, for each Interconnector BM Unit, the Transmission Loss Multiplier shall be calculated as follows:

3. SETTLEMENT OF BALANCING ACTIONS

3.1 Conversion of Data Received from the NETSO

3.1.1 It is recognised that Final Physical Notification Data, Bid-Offer Pairs and Acceptance Data derived from data submitted or determined under the Grid Code (and received by the SAA from the NETSO) will contain values with associated from/to times whereas the equivalent data required for the purposes of this Section T are required to contain point values (as defined in Annex X-2).

3.1.2 Accordingly, the SAA shall convert such data received from the NETSO for the purposes of Settlement using the following conventions:

(a) in the case of Final Physical Notification Data:

(i) each value, comprising a MW 'from' level and associated 'from' time and a MW 'to' level and associated 'to' time, shall be allocated a Point Value Identification Number;

(ii) the 'to' MW level and associated 'to' time shall be a Point FPN (^fFPN_ijt) which is allocated a Point Value Identification Number of '1';

(iii) the 'from' MW level and associated 'from' time shall be a Point FPN (^fFPN_ijt) which is allocated a Point Value Identification Number of '2';

(iv) the associated time of each Point FPN with a Point Value Identification Number of 2 shall be equal to the associated time of the Point FPN with a Point Value Identification Number of 1 of the immediately preceding pair of Point FPNs;

(b) in the case of Bid-Offer Pairs:

(i) each value, comprising a MW 'from' level and associated 'from' time and a MW 'to' level and associated 'to' time, shall be allocated a Point Value Identification Number;

(ii) the 'to' MW level and associated 'to' time shall be a Point Bid-Offer Volume (^fqBOⁿ_ijt) which is allocated a Point Value Identification Number of '1';

3.1.4 It is recognised that Replacement Reserve Activation Data, GB Need Met Data and Interconnector Schedule Data derived from data submitted or determined under the Grid Code (and received by the SAA from the NETSO) will contain values with an associated Position and Replacement Reserve Auction Period Resolution Type whereas the equivalent data required for the purposes of this Section T are required to contain Quarter Hour values (as defined in Annex X-2).

3.1.5 Accordingly, the SAA shall convert such data received from the NETSO for the purposes of Settlement using the following conventions:

(a) in the case of, respectively, Replacement Reserve Activation Data, GB Need Met Data and Interconnector Schedule Data:

(i) each Position shall be equal to the duration of the Replacement Reserve Auction Period Resolution Type and have an associated Flow Direction, Replacement Reserve Activation Price and Activated Quantity;

(ii) for the purposes of the Code, each Position shall be fully comprised of Quarter Hours;

(iii) each Quarter Hour within a Position shall be allocated:

(1) a Quarter Hour 'J' expressed as an integer;

(2) a Quarter Hour Replacement Reserve Activation Price being the price associated with such Position pursuant to paragraph 3.1.5(a)(i) (where a Position is comprised of more than one Quarter Hour then each Quarter Hour in such Position shall be allocated the same Replacement Reserve Activation Price); and

(3) an Quarter Hour RR Activated Quantity associated being the Activated Quantity associated with such Position pursuant to paragraph 3.1.5(a)(i) (where a Position is comprised of more than one Quarter Hour then each Quarter Hour in such Position shall be allocated the same Activated Quantity) multiplied by 1 should the associated Flow Direction reference 'UP'; or multiplied by -1 should the associated Flow Direction reference 'DOWN';

(i) a point variable shall be created where the time t shall be set five minutes before the 'start time' of the Quarter Hour period that the Quarter Hour RR Activation relates to and the MW level shall be set equal to the Quarter Hour RR Activated Quantity for the immediately preceding Quarter Hour RR Activation that time t relates to. If no immediately preceding Quarter Hour RR Activation exists then the MW Level shall be set to zero;

(ii) a point variable shall be created where the time t shall be set five minutes after the 'start time' of the Quarter Hour period that the Quarter Hour RR Activation relates to and the MW level shall be set equal to the Quarter Hour RR Activated Quantity MW level of the Quarter Hour RR Activation;

(iii) a point variable shall be created where the time t shall be set five minutes before the 'end time' of the Quarter Hour period that the Quarter Hour RR Activation relates to and the MW level shall be set equal to the Quarter Hour RR Activated Quantity MW level of the Quarter Hour RR Activation;

(iv) a point variable shall be created where the time t shall be set five minutes after the 'end time' of the Quarter Hour period that the Quarter Hour RR Activation and the MW level shall be set equal to zero;

Part 2 - Detailed Provisions

12. CADL FLAGGING

12.1 In relation to each Acceptance, k, for a particular BM Unit, another Acceptance for the same BM Unit is "related" to Acceptance k where such other Acceptance has a Bid-Offer Acceptance Time that falls within the period:

(a) from and including the spot time at the start of the Settlement Period which falls three Settlement Periods prior to the Settlement Period in which the Bid-Offer Acceptance Time for Acceptance k falls, and

(b) to and including the spot time at the end of the Settlement Period which falls three Settlement Periods after the Settlement Period in which the Bid-Offer Acceptance Time for Acceptance k falls.

12.2 In relation to each Acceptance k, another Acceptance is "continuous" with Acceptance k if it is related to Acceptance k, and:

(a) the spot time associated with:

(i) the first Point Acceptance Volume of the Acceptance is earlier, and

(ii) the last Point Acceptance Volume of the Acceptance is not earlier

than the spot time associated with the first Point Acceptance Volume of Acceptance k; or

(b) the spot time associated with:

(i) the last Point Acceptance Volume of the Acceptance is later, and

(ii) the first Point Acceptance Volume of the Acceptance is not later than

the spot time associated with the last Point Acceptance Volume of Acceptance k; or

(c) the Acceptance is continuous (in accordance with paragraph (a) or (b)) with another Acceptance which is determined (including, for the avoidance of doubt, by virtue of this paragraph (c)) to be a continuous Acceptance in relation to Acceptance k.

12.3 In relation to each Acceptance k, for a particular BM Unit, the Continuous Acceptance Duration (CAD^k_i) shall be the duration of the period:

(a) commencing at the earliest spot time associated with:

(i) any value of Point Acceptance Volume for Acceptance k; or

(ii) any Point Acceptance Volume for any Acceptance that is a continuous Acceptance in relation to Acceptance k, and

(b) ending at the latest spot time associated with:

(i) any value of Point Acceptance Volume for Acceptance k; or

(ii) any Point Acceptance Volume for any Acceptance that is a continuous Acceptance in relation to Acceptance k.

12.4 In relation to each accepted Offer and accepted Bid in the Ranked Sets of System Actions, if (for the associated Acceptance k) CAD^k_i < CADL, then the accepted Offer or accepted Bid shall be CADL Flagged.

12.5 In relation to each Demand Control Volume, the Continuous Acceptance Duration (CAD) shall be the duration of the period:

(a) commencing at the Demand Control Event Start Point; and

(b) ending at the Demand Control Event End Point.

12.6 In relation to each Demand Control Volume in the Ranked Sets of System Actions, if CAD < CADL, then the Demand Control Volume shall be CADL Flagged.

13. ARBITRAGE TAGGING

13.1 In respect of each Settlement Period, System Actions in the De Minimis Tagged Ranked Sets of System Actions will be defined as Arbitrage Tagged in the following way.

13.2 If, for the highest priced System Sell Action, QSS^g_j (if any) which is not already an Arbitrage Tagged System Sell Action, there exists any System Buy Action QSB^w_j which is not already an Arbitrage Tagged System Buy Action for which it is true that SAP^w_j

\leq

SAP^g_j, then the following procedure will be carried out:

(a) All System Buy Actions for which SAP^w_j

\leq

SAP^g_j will be ranked in price order, lowest priced first.

(b) The set of such System Buy Actions

\{{Q S B}^{w_{1}}_{j}, {Q S B}^{w_{2}}_{j}, \dots, {Q S B}^{w_{w}}_{j}\}

is then a ranked set of System Buy Actions for all of which it is true that SAP^w_j

\leq

SAP^g_j.

\sum_{}^{v} {Q S B}^{w_{v}}_{j} \leq - {Q S S}^{g}_{j}

where

\sum_{}^{v}

is the sum over all ranked System Buy Actions up to v,

the

{Q S B}^{w_{v}}_{j}

will be defined as Arbitrage Tagged and the fraction

φ

{Q S S}^{g}_{j}

which is equal to

\sum_{}^{v} (- {Q S B}^{w_{v}}_{j})

will be defined as Arbitrage Tagged (this fraction may be one (1)).

(d) If:

\sum_{}^{v} {Q S B}^{w_{v}}_{j} \leq - {Q S S}^{g}_{j}

where Σ^vis the sum over all ranked System Buy Actions up to v,

then, if a ranked System Buy Action, v+1 exists, the fraction

γ

{Q S B}^{w_{v + 1}}_{j}

which satisfies

\sum_{}^{v} {Q S B}^{w_{v}}_{j} + γ * {Q S B}^{w_{v + 1}}_{j} = - {Q S S}^{g}_{j}

will also be defined as Arbitrage Tagged and

{Q S S}^{g}_{j}

will be defined as Arbitrage Tagged.

13.3 The process in paragraph 13.2 will then be repeated for the highest priced System Sell Action (if any) that remains not Arbitrage Tagged.

13.4 If, for the purposes of carrying out the procedure in paragraph 13.2:

(a) there are two or more System Sell Actions that are not Arbitrage Tagged, that have the same highest System Action Price, or

(b) there are two or more ranked System Buy Actions that have the same System Action Price

then one of the System Sell Actions or (as the case may be) System Buy Actions will be selected at random.

13.5 If the completed application of paragraphs 13.1 to 13.4 inclusive (the 'initial calculation') would result in there being any System Sell Action or ranked System Buy Action which:

(a) is not Arbitrage Tagged, but

(b) has the same price (other than merely by virtue of being a fraction

(1 - γ)

(1 - φ)

pursuant to the initial calculation) as a System Sell Action or (as the case may be) ranked System Buy Action which is Arbitrage Tagged,

then:

(i) all such System Sell Actions

{Q S S}^{w_{r}}_{j}

or ranked System Buy Actions

{Q S B}^{w_{r}}_{j}

(whether or not Arbitrage Tagged on the basis of the initial calculation) which have the same price are "threshold" System Actions;

(ii) no threshold System Action shall be defined as Arbitrage Tagged pursuant to the relevant provision, but instead the fraction

δ

of each threshold System Sell Action

{Q S S}^{w_{r}}_{j}

or threshold System Buy Action

{Q S B}^{w_{r}}_{j}

which satisfies the following shall be defined as Arbitrage Tagged:

δ * \sum_{}^{w_{r}} {Q S S}^{w_{r}}_{j} = \sum_{}^{w_{r'}} {Q S S}^{w_{r'}}_{j}

or (as the case may be)

δ * \sum_{}^{w_{r}} {Q S B}^{w_{r}}_{j} = \sum_{}^{w_{r'}} {Q S B}^{w_{r'}}_{j}

where

\sum_{}^{w_{r}}

is the sum over all threshold System Sell Actions or (as the case may be) threshold System Buy Actions, and

\sum_{}^{w_{r'}}

is the sum over all threshold System Sell Actions or (as the case may be) threshold System Buy Actions (including a fraction

γ

φ

) which, on the basis of the initial calculation would have been defined as Arbitrage Tagged.

14. NIV TAGGING

14.1 In respect of each Settlement Period, the Net Imbalance Volume will be determined as follows:

NIV_j = Σ_w QSB^w_j – Σ_w (-QSS^w_j)

where Σ_w is the sum over all System Actions in the Classified Ranked Sets.

14.2 In respect of each Settlement Period, System Actions in the Classified Ranked Sets will be defined as NIV Tagged in the following way.

(a) If:

\sum_{}^{w'} (- {Q S S}^{w'}_{j}) = 0

where

\sum_{}^{w'}

is the sum over System Sell Actions in the Classified Ranked Set; or

\sum_{}^{w^{*}} {Q S B}^{w^{*}}_{j} = 0

where

\sum_{}^{w^{*}}

is the sum over System Buy Actions in the Classified Ranked Set:

then no System Actions will be NIV Tagged.

Otherwise, the following procedure will be carried out.

(b) If:

\sum_{}^{w'} ({- Q S S}^{w'}_{j}) \leq \sum_{}^{w^{*}} {Q S B}^{w^{*}}_{j}

where

\sum_{}^{w'}

is the sum over the System Sell Actions and

\sum_{}^{w^{*}}

is the sum over the System Buy Actions in the Classified Ranked Sets,

then all the System Sell Actions (for all values of w’) in the Ranked Set of System Sell Actions will be defined as NIV Tagged.

\sum_{}^{w'} ({- Q S S}^{w'}_{j}) \leq \sum_{}^{w^{*}} {Q S B}^{w^{*}}_{j}

there must exist a number e and a number

φ

(which may be a fraction or zero) for which

\sum_{}^{w'} ({- Q S S}^{w'}_{j}) = \sum_{}^{w_{v > e}^{*}} {Q S B}^{w_{v_{j}}^{*}} + φ * {Q S B}^{w_{e_{j}}^{*}}

where

\sum_{}^{w'}

is the sum over all System Sell Actions and

\sum_{}^{w_{v > e}^{*}}

is the sum over those System Buy Actions for which v is greater than e.

Subject to paragraph (f), each System Buy Action numbered e+1 or higher in the Classified Ranked Set for which this is true will be defined as NIV Tagged. If

φ

is a fraction rather than zero, then the fraction

φ

of the System Buy Action numbered e will be defined as NIV Tagged.

(d) If:

Σ^w’ (-QSS^w’_j) > Σ^w*QSB^w*_j

where Σ^w’ is the sum over the System Sell Actions and Σ^w* is the sum over the System Buy Actions,

then all the System Buy Actions (for all values of w*) in the Ranked Set of System Buy Actions will be defined as NIV Tagged.

(e) Since Σ^w’ (-QSS^w’_j) > Σ^w*QSB^w*_j there must exist a number e and a number

φ

(which may be a fraction or zero) for which

\sum_{}^{w^{*}} {Q S B}^{w^{*}}_{j} = \sum_{}^{{w'}_{v > e}} ({- {Q S S}^{{w'}_{v}}}_{j}) + φ * {- Q S S}^{{w'}_{e}}_{j}

where

\sum_{}^{w^{*}}

is the sum over all System Buy Actions and

\sum_{}^{{w'}_{v > e}}

is the sum over those System Sell Actions for which v is greater than e.

Subject to paragraph (f), each System Sell Action numbered e+1 or higher in the Classified Ranked Set for which this is true will be defined as NIV Tagged. If

φ

is a fraction rather than zero, then the fraction

φ

of the System Sell Action numbered e will be defined as NIV Tagged.

(f) However, for each of paragraphs (c) and (e) (each a "relevant provision") separately, if the application of the relevant provision (the "initial calculation") would result in there being any System Action which:

(1) is not defined as NIV Tagged, but

(2) has the same price (including a NULL price) (other than merely by virtue of being a fraction (1 -

φ

) pursuant to the initial calculation) as, in the case of a System Buy Action, a System Buy Action which is NIV Tagged or, in the case of a System Sell Action, a System Sell Action which is NIV Tagged,

then:

(i) all such System Buy Actions

{Q S B}^{{w'}_{r}}_{j}

or System Sell Actions

{Q S S}^{{w'}_{r}}_{j}

(whether or not NIV Tagged on the basis of the initial calculation) which have the same price are "threshold" System Actions;

(ii) no threshold System Action shall be defined as NIV Tagged pursuant to the relevant provision, but instead the fraction

δ

of each threshold System Buy Action

{Q S B}^{{w'}_{r}}_{j}

or threshold System Sell Action

{Q S S}^{{w'}_{r}}_{j}

which satisfies the following shall be defined as NIV Tagged:

δ * \sum_{}^{{w'}_{r}} {Q S B}^{{w'}_{r}}_{j} = \sum_{}^{{w'}_{r'}} {Q S B}^{{w'}_{r'}}_{j}

or (as the case may be)

δ * \sum_{}^{{w'}_{r}} {Q S S}^{{w'}_{r}}_{j} = \sum_{}^{{w'}_{r'}} {Q S S}^{{w'}_{r'}}_{j}

where

\sum_{}^{{w'}_{r}}

is the sum over all threshold System Buy Actions or (as the case may be) threshold System Sell Actions, and

\sum_{}^{{w'}_{r'}}

is the sum over all threshold System Buy Actions or (as the case may be) threshold System Sell Actions (including a fraction

φ

thereof) which, on the basis of the initial calculation would have been defined as NIV Tagged.

15. REPLACEMENT PRICE

15.1 In respect of each Settlement Period, the Replacement Buy Price or Replacement Sell Price will be determined as follows.

15.2 If NIV is positive:

(a) if there are no Unflagged System Actions in the NIV Tagged Ranked Set, the Replacement Buy Price shall be the Market Price, unless the Market Price is undefined in which case the Replacement Buy Price shall be zero;

(b) otherwise, the Replacement Buy Price shall be determined as:

RBP_j = Σ^w' (QSB^w'_j * SAP^w'_j) / Σ^w' QSB^w'_j

where

Σ^w'is the sum over all Qualifying Unflagged System Actions in the NIV Tagged Ranked Set.

15.3 For the purposes of paragraph 15.2:

(a) if

\sum_{}^{w} {Q S B}^{w}_{j} \leq R P A R

, all Unflagged System Buy Actions in the NIV Tagged Ranked Set will be defined as Qualifying;

(b) if

\sum_{}^{w} {Q S B}^{w}_{j} > R P A R

(i) the Unflagged System Buy Actions in the NIV Tagged Ranked Set shall be ranked in price order, lowest priced first;

(ii) as

\sum_{}^{w} {Q S B}^{w}_{j} > R P A R

there must exist a number f and a number

\emptyset

(which may be a fraction or zero) for which:

R P A R = \sum_{}^{{w'}_{v > f}} {Q S B}^{{w'}_{v}}_{j} + \emptyset * ({Q S B}^{{w'}_{f}}_{j})

where

\sum_{}^{{w'}_{v > f}}

is the sum over those System Buy Actions for which v is greater than f.

(iii) each of the System Buy Actions numbered f+1 or higher in the Ranked Set of Unflagged System Buy Actions for which this is true will be defined as Qualifying. If

\emptyset

is a fraction rather than zero, then the fraction (

\emptyset

) of the System Buy Action numbered f will be defined as Qualifying.

15.4 If NIV is negative or zero:

(a) if there are no Unflagged System Actions in the NIV Tagged Ranked Set the Replacement Sell Price shall be the Market Price, unless the Market Price is undefined in which case the Replacement Sell Price shall be zero;

(b) otherwise, the Replacement Sell Price shall be determined as:

RSP_j = Σ^w' (QSS^w'_j * SAP^w'_j) / Σ^w' QSS^w'_j

where

Σ^w'is the sum over all Qualifying Unflagged System Actions in the NIV Tagged Ranked Set

15.5 For the purposes of paragraph 15.4:

(a) if Σ^w –QSS^w_j £ RPAR, all Unflagged System Sell Actions in the NIV Tagged Ranked Set will be defined as Qualifying;

(b) if Σ^w –QSS^w_j > RPAR:

(i) the Unflagged System Sell Actions in the NIV Tagged Ranked Set shall be ranked in price order, highest priced first;

(ii) as Σ^w -QSS^w_j > RPAR there must exist a number f and a number

\emptyset

(which may be a fraction or zero) for which:

R P A R = \sum_{}^{{w'}_{v > f}} - {Q S S}^{{w'}_{v}}_{j} + \emptyset * ({- Q S S}^{{w'}_{f}}_{j})

where

\sum_{}^{{w'}_{v > f}}

is the sum over those System Sell Actions for which v is greater than f;

(iii) each of the System Sell Actions numbered f+1 or higher in the Ranked Set for which this is true will be defined as Qualifying. If

\emptyset

is a fraction rather than zero, then the fraction (

\emptyset

) of the System Sell Action numbered f will be defined as Qualifying.

16. PAR TAGGING

16.1 In respect of each Settlement Period, System Actions in the Replacement-Priced Ranked Set will be defined as PAR Tagged in the following way:

(a) If:

\sum_{}^{w'} {Q S B}^{w'}_{j} \leq P A R

where

\sum_{}^{w'}

is the sum over the System Buy Actions in the Replacement-Priced Ranked Set

then none of the System Buy Actions (for all values of w') will be defined as PAR Tagged.

(b) If Σ^w' (QSB^w'_j) > PAR there must exist a number f and a number

\emptyset

(which may be a fraction or zero) for which

P A R = \sum_{}^{{w'}_{v > f}} {Q S B}^{{w'}_{v}}_{j} + \emptyset * {Q S B}^{{w'}_{f}}_{j}

where

\sum_{}^{{w'}_{v > f}}

is the sum over those System Buy Actions for which v is greater than f.

Subject to paragraph (e), each System Buy Action numbered 1 to f-1 in the Replacement-Priced Ranked Set for which this is true will be defined as PAR Tagged. If

\emptyset

is a fraction rather than zero, then the fraction

(1 - φ)

of the System Buy Action numbered f will be defined as PAR Tagged.

\sum_{}^{w'} ({- Q S S}^{w'}_{j}) \leq P A R

where

\sum_{}^{w'}

is the sum over the System Sell Actions in the Replacement-Priced Ranked Set

then none of the System Sell Actions (for all values of w') will be defined as PAR Tagged.

(d) If Σ^w' (-QSS^w'_j) > PAR there must exist a number f and a number

\emptyset

(which may be a fraction or zero) for which

P A R = \sum_{}^{{w'}_{v > f}} ({- {Q S S}^{{w'}_{v}}}_{j}) + \emptyset * (- {Q S S}^{{w'}_{f}}_{j})

where

\sum_{}^{{w'}_{v > f}}

is the sum over those System Sell Actions for which v is greater than f.

Subject to paragraph (e), each of the System Sell Actions numbered 1 to f-1 in the Replacement-Priced Ranked Set for which this is true will be defined as PAR Tagged. If

\emptyset

is a fraction rather than zero, then the fraction

(1 - φ)

of the System Sell Action numbered f will be defined as PAR Tagged.

(e) However, for each of paragraphs (b) and (d) (each a "relevant provision") separately, if the application of the relevant provision (the "initial calculation") would result in there being any System Buy Action or System Sell Action which:

(1) is not defined as PAR Tagged, but

(2) has the same price (including a NULL price) (other than merely by virtue of being a fraction

\emptyset

pursuant to the initial calculation) as a System Buy Action or (as the case may be) a System Sell Action which is PAR Tagged,

then:

(i) all such System Buy Actions

{Q S B}^{{w'}_{r}}_{j}

or System Sell Actions

{Q S S}^{{w'}_{r}}_{j}

(whether or not PAR Tagged) which have the same price are "threshold" System Actions;

(ii) no threshold System Action shall be defined PAR Tagged pursuant to the relevant provision, but instead the fraction

δ

of each threshold System Buy Action

{Q S B}^{{w'}_{r}}_{j}

or threshold System Sell Action

{Q S S}^{{w'}_{r}}_{j}

which satisfies the following shall be defined as PAR Tagged:

δ * \sum_{}^{{w'}_{r}} {Q S B}^{{w'}_{r}}_{j} = \sum_{}^{{w'}_{r'}} {Q S B}^{{w'}_{r'}}_{j}

or (as the case may be)

δ * \sum_{}^{{w'}_{r}} {Q S S}^{{w'}_{r}}_{j} = \sum_{}^{{w'}_{r'}} {Q S S}^{{w'}_{r'}}_{j}

where

\sum_{}^{{w'}_{r}}

is the sum over all threshold System Buy Actions or (as the case may be) threshold System Sell Actions, and

\sum_{}^{{w'}_{r'}}

is the sum over all threshold System Buy Actions or (as the case may be) threshold System Sell Actions (including a fraction

(1 - φ)

thereof) which, on the basis of the initial calculation would have been defined as PAR Tagged.

Annex T-2: Transmission Loss Factors

1. Introduction

1.1 This Annex T-2 sets out the basis for determining Transmission Loss Factors.

1.2 Transmission Loss Factors will be determined by the TLFA:

(a) by reference to Nodal TLFs determined by the application of the Load Flow Model in accordance with paragraph 8.2; and

(b) in accordance with the further provisions of paragraph 8.

1.3 For the purposes of this Annex T-2:

(a) a "node" is a point on an electrical network at which:

(i) a power flow on to or off the network can occur; or

1A. Transmission Loss Factors relating to the BSC Year commencing 1st April 2025

1A.1 For the purposes of this paragraph 1A:

(a) the "Current BSC Year" means the BSC Year commencing 1st April 2025;

(b) the "Preceding BSC Year" means the BSC Year commencing 1st April 2024;

(d) the "TLF verification criteria" means the criteria set out in paragraph 1A.3.

1A.2 By no later than 21 November 2025 the Panel shall determine:

(a) whether the Transmission Loss Factors applicable to the Current BSC Year comply with the TLF verification criteria; and

(b) where those Transmission Loss Factors are not in compliance with the TLF verification criteria, that the Transmission Loss Factors should be recalculated. Any such recalculation shall:

(i) give effect to the Panel’s determination under paragraph 1A.3;

(ii) otherwise be determined in accordance with this Annex T-2; and

(c) a timetable for performing the activities set out in this paragraph 1A (whether or not the Panel has determined that a recalculation is required),

and each Party and the TLFA shall comply with any such instructions and timetable determined by the Panel under this paragraph.

1A.3 The criteria referred to in paragraph 1A.2 are as follows:

(a) that the Seasonal Zonal TLF (TLFZS) values reflect the expected change in total variable losses from a marginal change in demand or generation (averaged across each Season, and across the Nodes in each Zone). The expected change is the change that might reasonably be expected (based on expectations when BSC Modification P350 was approved, and on the TLF values previously used in Settlement); and

(b) to the extent that (a) is not met, whether a recalculation using amended input data is likely to yield TLFZS values that do substantially improve compliance with (a).

1A.4 With effect from the later of 1st April 2025 or the Relevant Implementation Date of Modification P485, but subject to paragraph 1A.5, the Transmission Loss Factors to be used for the purposes of Section T2 shall be the Transmission Loss Factors determined for the Preceding BSC Year.

1A.5 Following a determination by the Panel under paragraph 1A.2 (and, where applicable, the recalculation of Transmission Loss Factors), the Transmission Loss Factors for the Current BSC Year, for the purposes of Section T2, shall be:

(a) where the Panel has determined that no recalculation of Transmission Loss Factors for the Current BSC Year is required, the Transmission Loss Factors originally determined for the Current BSC Year by the TLFA and published on the BSC Website in December 2024; or

(b) where the Panel has required the recalculation of Transmission Loss Factors, the Transmission Loss Factors that have been recalculated pursuant to paragraph 1A.2,

and such Transmission Loss Factors shall take effect from and including the first BSC Season that commences immediately following the Panel’s determination.

1A.6 The Panel’s determinations (including any recalculation of Transmission Loss Factors under paragraph 1A.2) shall, in the absence of manifest error, be final and binding on all Parties.

2. LFM Specification

2.1 The Panel shall, in consultation with the NETSO and other Parties and the Authority, establish (to form part of the BSC Service Description for the TLFA) a specification ("LFM Specification") for a load flow model for the AC Transmission System, to operate based on the data inputs specified in paragraph 8.2(f), and consistent with the requirements in paragraph 2.2.

2.2 The LFM Specification shall provide for the following assumptions and approximations to be made in the load flow model:

(a) only electrical losses associated with power flows between adjacent nodes (forming part of the network) ("Load Flow Model power flows") will be used in determining nodal TLFs; and

(b) in respect of the power flow between adjacent nodes it is assumed:

(i) there is no Reactive Power component;

(ii) the ratio of the change of power flow over a circuit to the injection of power at a given node is not dependent on the overall electrical load on the network;

(iii) the sine of the voltage phase angle is equal to the phase angle (as measured in radians); and

(iv) the power flow in a circuit is equal to the difference in the voltage phase angles across the circuit multiplied by the circuit susceptance.

3. Load Flow Model

3.1 The TLFA shall establish, and (subject to paragraph 3.2) adopt and from time to time modify, a load flow model which implements and complies with the LFM Specification.

3.2 The TLFA shall not adopt such load flow model or a modification thereof unless the model reviewer has reported to the Panel (in such terms, and as to such materiality, as the Panel may decide) that such model or modification complies with the LFM Specification and the Panel accepts such model or modification; and the TLFA shall not modify the Load Flow Model except as the Panel may instruct or agree.

3.3 The Panel shall appoint, and may from time to time reappoint or replace, an independent expert (the "model reviewer") for the following purposes:

(a) to inspect and test the Load Flow Model and report to the Panel as to the compliance of the Load Flow Model with the LFM Specification or any particular aspect of the LFM Specification:

(i) before the Load Flow Model is first used for the purposes of this Annex T-2;

(ii) upon any modification of the Load Flow Model (whether upon a change to the LFM Specification or otherwise); and

(iii) on any other occasion on which the Panel decides to obtain such a report; and

(b) to verify and report to the Trading Disputes Committee as to whether Nodal TLFs were determined in accordance with the Load Flow Model, on any occasion on which it is necessary to do so for the purposes of any Trading Dispute.

3.4 Any report produced by the model reviewer on Nodal TLFs for the Trading Disputes Committee shall be final and binding on all Parties (save in the case of fraud or manifest error) and if a Party refers a Trading Dispute to arbitration under Section W3.6, then save in the case of fraud or manifest error, the arbitrator(s) appointed in accordance with Section H7 shall not have the power to query, review or in any way revise the model reviewer's report on whether Nodal TLFs were, or were not, determined in accordance with the Load Flow Model.

3.5 BSCCo shall enter into a contract of engagement (for the term for which the model reviewer is appointed) with the model reviewer, which shall, inter alia:

(b) the TLFA shall be responsible for the payment of all fees due to the escrow agent.

3.7 The TLFA shall be required to make the Load Flow Model (and any details thereof) available to the model reviewer and the BSC Auditor (and as may be required by the arbitral tribunal in connection with any arbitration); but shall not be required to make available or disclose the Load Flow Model or details thereof to the Panel, any Panel Committee or Parties other than to BSCCo as required for the provision of the reports set out in Table 9 in Annex V-1 or in accordance with the release terms included in the escrow agreement pursuant to paragraph 3.6.

3.8 Subject to paragraph 3.4, once the Load Flow Model (or any modification thereof) has been adopted by the TLFA, Nodal TLFs which are properly determined by the Load Flow Model shall be definitive; and accordingly:

(a) (without prejudice to any question as to whether such Nodal TLFs were in fact properly determined) no Party may challenge or question on any grounds the validity of any Nodal TLF which was so determined; and

(b) any modification of the Load Flow Model shall have effect only prospectively, that is for the purposes of determining Transmission Loss Factors in respect of BSC Years for which (at the time the modification was made) Transmission Loss Factors have not already been determined in accordance with paragraph 8.

3.9 For the purposes of paragraph 3.8(a), Nodal TLFs are properly determined if they are determined by and only by the application of the Load Flow Model on the basis of data input in compliance with the further provisions of this Annex T-2.

1.4 Information required by the Panel

1.4.1 Subject to paragraph 1.4.2, each Party shall provide to the Panel, any Panel Committee and BSCCo all such data and information as the Panel may reasonably require in order to enable the Panel, such Panel Committee or BSCCo properly to carry out its functions and responsibilities under the Code.

(b) such rejection or refusal shall not be invalidated by, and the obligations and liabilities of the Party under the Code shall not be prejudiced or affected by, any failure of such BSC Agent to give such reasons; and

(c) any failure of a BSC Agent to give reasons for such rejection or refusal may not, of itself, give rise to a Trading Dispute.

(b) each relevant BSC Agent shall

retain settlement data in accordance with this paragraph 1.6, to enable such data to be provided and used for the purposes of the resolution of Trading Disputes, any related arbitration, and the carrying out of any Post-Final Settlement Run, Post-Final Volume Allocation Run or Extra-Settlement Determination.

(b) thereafter, until the date forty months after the Settlement Day to which it relates, subject to paragraph 1.6.4, in an archive or any other form (including, for the avoidance of doubt, in the form referred to in paragraph 1.6.3(a)) in which the data can be retrieved if requested within ten Business Days, sent for use in and used in carrying out an Extra-Settlement Determination as provided in the relevant Code Subsidiary Document.

1.6.4 Where the Panel (on the advice of BSCCo, the Trading Disputes Committee or otherwise) has informed Parties and relevant BSC Agents that settlement data (or particular settlement data) relating to a particular Settlement Day may be required for any of the purposes mentioned in paragraph 1.6.1 after the date specified in paragraph 1.6.3(b) then that settlement data is required to be held pursuant to paragraph 1.6.3(a) or (b) (as the case may be) until such time as the Panel notifies Parties and relevant BSC Agents that such data is no longer required to be so held.

1.6.5 The reference in Section J4.2.3 to "data" shall be construed as including settlement data.

2. SETTLEMENT

2.1 Settlement Frequency and Settlement Runs

2.1.1 For the purposes of the Code, settlement of Trading Charges (including Reconciliation Charges) in respect of a Settlement Day is to take place:

(a) on an initial basis and on each of four further occasions in accordance with the timetable established pursuant to Section N3;

(b) following a Post-Final Settlement Run, in accordance with the timetable established by the Panel pursuant to paragraph 2.2.5.

2.1.2 Without prejudice to Section T1.4, Settlement Runs and Volume Allocation Runs (for Central Volume Allocation and Supplier Volume Allocation) are to be carried out so as to meet the requirements of paragraph 2.1.1 using the latest data available.

2.1.3 Where at any time:

(a) any Reconciliation Settlement Run or Reconciliation Volume Allocation Run is to be carried out, and

(b) pursuant to any Code Modification, there has been any change since the preceding such run in any provision of the Code applicable to the carrying out of such run,

the Reconciliation Settlement Run or Reconciliation Volume Allocation Run shall be carried out by reference to the provisions of the Code prevailing as at the Settlement Day in respect of which it is to be carried out, unless the relevant Code Modification provided otherwise.

2.2 Post-Final Settlement Runs and Extra-Settlement Determinations

2.2.1 The Parties acknowledge that there may be occasions when it is necessary or appropriate:

(a) to carry out a Settlement Run (and related Volume Allocation Runs) in relation to a Settlement Day, after the Final Reconciliation Settlement Run and related Final Reconciliation Volume Allocation Run;

(b) to carry out a determination, outside Volume Allocation Runs and Settlement Runs, of Trading Charges (or adjustment and apportionment in respect thereof) in relation to a Settlement Day (whether or not after the Final Reconciliation Settlement Run and related Final Reconciliation Volume Allocation Run).

2.2.2 Subject to paragraph 2.2.2A and paragraph 2.2.4, the Trading Disputes Committee may determine following resolution of a Trading Dispute:

(a) that, after the Final Reconciliation Settlement Run and related Final Reconciliation Volume Allocation Run, a Post-Final Settlement Run should be carried out in relation to a Settlement Day or part thereof; provided that no more than one Post-Final Settlement Run may be carried out in respect of any one Settlement Day;

(b) that, at any time, an Extra-Settlement Determination should be carried out in accordance with paragraph 2.2.3 in relation to a Settlement Day or part thereof.

2.2.2A The provisions of paragraph 2.2.2 shall apply mutatis mutandis to the Panel as if the reference therein to:

(a) the Trading Disputes Committee were a reference to the Panel; and

(b) the resolution of a Trading Dispute were a reference to the award of an arbitrator or otherwise in the Panel’s discretion.

2.2.3 Subject to paragraph 2.2.3C, where an Extra-Settlement Determination is to be carried out:

(a) there shall be determined amounts

(i) by reference to the differences between the amounts of Trading Charges determined pursuant to the Extra-Settlement Determination and such amounts as determined in the Settlement Run (for the relevant Settlement Day) preceding such Extra-Settlement Determination, or

(ii) otherwise by way of adjustment and apportionment in respect of Trading Charges as the Trading Disputes Committee shall determine

which each Trading Party and the NETSO shall be entitled to be paid by or liable to pay to the BSC Clearer;

(b) such entitlements and liabilities shall be Ad-Hoc Trading Charges for the purposes of Section N6.9;

(c) the Trading Disputes Committee shall determine the method by which Trading Charges, or adjustment and apportionment in respect thereof, are to be determined;

(d) each Party and each BSC Agent shall comply with the reasonable requests of the Trading Disputes Committee in connection with such method of determination;

(e) such determination may be made on such estimated or approximate basis as the Trading Disputes Committee may decide is appropriate in the circumstances (having regard, without limitation, to whether any further Timetabled Reconciliation Settlement Run in relation to the relevant Settlement Day is to take place after the Extra-Settlement Determination);

(f) without prejudice to the generality of paragraph (e), subject to paragraph (g), unless the Final Reconciliation Settlement Run and related Final Reconciliation Volume Allocation Run for the relevant Settlement Day have already taken place, such determination may (where appropriate in the Trading Disputes Committee’s opinion) be made so that:

(i) extra-settlement amount(s), so far as being amounts payable to Trading Parties or the NETSO, are determined and payable only as to a proportion (the "interim proportion") of the amounts that would be payable on the basis of an exact determination of the relevant Trading Charge(s) in accordance with the Code; and

(ii) extra settlement amounts so far as relating to Daily Party residual Settlement Cashflow payable by Trading Parties, are determined for and payable by or to some Trading Parties only (each an "included" Trading Party)

where "extra-settlement amounts" means the amounts payable pursuant to paragraph (b) by way of Ad-Hoc Trading Charges pursuant to an Extra-Settlement Determination;

(g) where a determination is made in accordance with paragraph (f), so far as relating to Daily Party Residual Settlement Cashflow:

(i) the interim proportion shall be determined (for the relevant Extra-Settlement Determination) by the Trading Disputes Committee;

(ii) the included Trading Parties shall be selected as follows, unless the Trading Disputes Committee decides that there are exceptional circumstances which justify a different method of selection:

(1) all Trading Parties shall be ranked in order of the magnitude of RCRC_p payable to them in respect of the relevant Settlement Day, largest first;

(2) the Trading Parties to be included shall be selected in the order ranked, until such Trading Parties have been selected that:

∑^ps RCRC_p = IP * ∑^p RCRC_p

where:

RCRC_p is the Daily Party Residual Settlement Cashflow for a Trading Party for the relevant Settlement Day as determined under the Settlement Run preceding the Extra-Settlement Determination;

IP is the interim proportion;

∑^ps is the sum over all selected Trading Parties;

∑^p is the sum over all Trading Parties;

(h) each Party shall be bound by the Extra-Settlement Determination, but without prejudice to paragraph 2.6.1; and

(i) where a relevant Settlement Run in relation to a Settlement Day is carried out after an Extra-Settlement Determination has been carried out in relation to that day:

(i) each Trading Party and the NETSO shall be entitled to be paid by or liable to pay to the BSC Clearer, on or as near as practicable to the Payment Date in respect of such Settlement Run, an amount calculated as:

(1) an amount equal and opposite to the extra-settlement amount paid by or to such Party, plus

(2) interest on the amount in paragraph (1)calculated on a compound basis in accordance with paragraph 2.2.3A; and

(ii) such entitlements and liabilities shall be Ad-Hoc Trading Charges for the purposes of Section N6.9.

A relevant Settlement Run for the purposes of this paragraph 2.2.3(i) is a Settlement Run (or, where relevant, the first Settlement Run) in which the Settlement Error in respect of which the Extra – Settlement Determination was carried out has been corrected.

2.2.3A For the purposes of paragraph 2.2.3(i), interest shall be calculated in respect of the period from (and including) the date when payment of the extra-settlement amount was due to (but not including) the Payment Date in respect of the relevant Settlement Run carried out after the Extra-Settlement Determination by applying the Base Rate:

(a) as prevailing at 00:00 hours on the relevant day on a daily compounded basis up to (but not including) the Invoice Date for the payment of the relevant Settlement Run; and

(b) as prevailing at 00:00 on the Invoice Date for the payment of the relevant Settlement Run on a daily compounded basis up to (but not including) the Payment Date.

2.2.3B The Implementation Date for the application of compound interest pursuant to paragraphs 2.2.3(i) and 2.2.3A shall be the Go-live Date.

2.2.3C The provisions of paragraph 2.2.3 shall apply mutatis mutandis to the Panel where, pursuant to paragraphs 2.2.2 and 2.2.2A the Panel determines that an Extra Settlement Determination should be carried out, as if references to the Trading Disputes Committee in paragraph 2.2.3 were references to the Panel.

2.2.4 Except pursuant to Section P6.5.1(c), no Settlement Run or Volume Allocation Run shall be carried out on any date which is more than twenty eight months after the Settlement Day to which such runs relate.

2.2.5 Where the Trading Disputes Committee or the Panel (as the case may be) decides that a Post-Final Settlement Run and Post-Final Volume Allocation Runs or an Extra-Settlement Determination should be carried out:

(a) the Panel shall set, after discussion with the SAA, FAA, CDCA and SVAA (and, where applicable, the CRA, ECVAA, NETSO and/or any Interconnector Administrator and/ or any Market Index Data Provider), a timetable for the carrying out of such runs;

(b) the Notification Date for such Settlement Run shall be specified in such timetable;

(c) BSCCo shall inform all Parties and BSC Agents of the decision to carry out such runs and the timetable set by the Panel for such runs.

2.5.3 For the purposes of paragraph 2.5.2, a relevant BSC Agent or relevant Party shall not adjust or revise any settlement data after such data has first been provided or reported to Parties (including pursuant to an Interim Information Settlement Run or Interim Information Volume Allocation Run), except:

(a) where it appears to the relevant BSC Agent or relevant Party that there is a Settlement Error (as defined in Section W) and:

SECTION W: TRADING DISPUTES

1. GENERAL

1.1 Introduction

1.1.1 This Section W sets out:

(a) arrangements for the resolution of Trading Disputes under the Code;

(b) arrangements for the establishment and operation of the Trading Disputes Committee;

(d) the effect of resolution of a Trading Dispute.

1.2 Resolution of Trading Disputes

1.2.1 Subject to paragraphs 1.2.3 and 1.2.4, and save where expressly provided to the contrary under the Code, and subject to any contrary provision of the Act, any Licence, any EMR Legal Requirement or the rights, powers and duties of the Authority or the Secretary of State under the Act or any Licence, each Party hereby agrees that:

(a) all Trading Disputes shall be raised, dealt with and (subject only to paragraph 3.6) decided in accordance with this Section W;

(b) no Party may refer a Trading Dispute to arbitration in accordance with Section H7 unless the Trading Dispute has first been so raised, dealt with and decided in accordance with the provisions of this Section W.

1.2.2 Each Party hereby waives to the fullest extent possible any rights, remedies or procedures which it may have or which may be available to it for the resolution of a Trading Dispute other than as provided in paragraph 1.2.1.

1.2.3 The Panel may, on the application of the Trading Disputes Committee or (provided such application is made reasonably promptly after the relevant query, dispute or difference arose) of a Party, determine in relation to a particular query, dispute or difference which amounts to a Trading Dispute:

(a) that there are also disputed matters, connected to such query, dispute or difference, which are outside the defined scope (in paragraph 1.3) of a Trading Dispute, and

(b) as a result, that paragraph 1.2.1 shall not apply in relation to such query, dispute or difference (or, where it is practicable to do so, that the procedures provided for in this Section W shall be varied so as to be co-ordinated with the procedures for resolving such other dispute);

and where the Panel so determines, paragraph 1.2.1 shall not apply in relation to the Trading Dispute or the procedures in this Section W shall be varied in relation thereto as determined by the Panel.

1.2.4 In a case in which a Party wishes to make a Third Party Claim (as defined in Section H7.2.3, and including a case within Section H7.2.2) and the Third Party Claim amounts to a Trading Dispute, then Section H7.2.1 shall apply and paragraph 1.2.1(a) shall not apply in relation to such Trading Dispute, unless the Trading Dispute has been raised and considered at a meeting of the Trading Disputes Committee before the legal proceedings (referred to in Section H7.2.1) have been commenced.

1.2.5 No Trading Dispute may be raised in respect of an affected Settlement Period after the "Dispute Deadline" as defined in paragraph 3.2; and accordingly a Party may not after such deadline refer to arbitration any matter relating to an affected Settlement Period which would constitute a Trading Dispute (except pursuant to paragraph 3.6 where such matter has been raised as a Trading Dispute before such deadline); and each Party hereby agrees to waive any right, claim or remedy it may have, whatsoever and howsoever arising, in respect of matters which, but for this paragraph 1.2.5, would constitute a Trading Dispute in respect of such affected Settlement Period.

1.2.6 The Dispute Deadline shall not, in any event, be later than:

(a) subject to paragraphs (b) and (c), the day which is twenty months after the Settlement Day in which the affected Settlement Period occurred; or

(b) if later where the alleged Settlement Error is an error in a Post-Final Settlement Run, either:

(i) where the Trading Disputes Committee or the Panel determine that there are exceptional circumstances, the date two months after the date of the Post-Final Settlement Run in which the Settlement Error first occurred; or

(ii) otherwise, the date one month after the date of the Post-Final Settlement Run in which the Settlement Error first occurred; or

(c) if later where the alleged Settlement Error is an error in an Extra-Settlement Determination the date one month after the date of the Post-Final Settlement Run or Extra-Settlement Determination in which the Settlement Error first occurred.

1.3 Trading Disputes

1.3.1 For the purposes of the Code:

(a) subject to paragraph 1.3.2, a "Trading Dispute" is any query, difference or dispute of whatsoever nature and howsoever arising under the Code as to:

(i) the existence, nature or effect of errors in:

(1) the data and/or processes used for the purposes of Settlement (including data required under the Retail Energy Code which has, or potentially has, an impact on Settlement); or

(2) the application of the rules for Settlement (whether generally or in relation to a particular Party or class of Parties),

to the extent such errors affect or may affect the allocation and/or determination of Trading Charges or the determination and settlement of amounts payable pursuant to Section N by reference to Trading Charges;

(ii) the existence, nature or effect of errors in the data and/or processes used for the purposes of, or in the application (whether generally or in relation to a particular Party or class of Parties) of the rules as to whether and when a Trading Party is in Credit Default under, Section M;

(b) a Trading Dispute or Settlement Error may, without prejudice to paragraph 3.2.2, refer to one or more Settlement Period(s) and to Settlement Period(s) in one or more Settlement Day(s); and

(c) an "affected Settlement Period" in relation to a Trading Dispute shall mean a Settlement Period in respect of which a Settlement Error has, or is alleged to have, occurred.

1.3.2 For the purposes of paragraph 1.3.1(a):

(a) references to errors in data and/or processes or in the application of rules are to such errors or omissions as a result of which the data produced from Settlement are not those which would have been produced had the provisions of the Code (including the provisions referred to in Section G, where applicable) been followed;

(b) data includes registration or standing data and errors in data include questions as to the validity and effectiveness of registrations;

(i) any query, difference or dispute as to whether or to what extent a Party is "responsible" for Exports or Imports for the purposes of Section K;

(ii) (as provided in, and subject to, paragraph 1.7) any dispute as to the identity at any time of the Registrant in CSS of a SVA Metering System;

(iii) disputes as to the charges payable by Suppliers pursuant to Annex S-1; and

(iv) disputes relating to the underlying input data items used by a Market Index Data Provider in the determination of its Market Index Data and/or to their inclusion or otherwise for these purposes (as opposed to queries by or between Parties in relation to Settlement as to whether the Market Index Definition Statement has been followed).

1.3.3 For the avoidance of doubt, a Trading Dispute may affect one or more Parties under the Code.

1.3.4 The Panel shall determine any question or disagreement as to whether or not a query, difference or dispute is a Trading Dispute for the purposes of the Code, and the decision of the Panel shall be binding on each Party and the Trading Disputes Committee; and for the purposes hereof:

(a) any Party or the Trading Disputes Committee may refer a question as to whether or not a query, difference or dispute is a Trading Dispute for determination by the Panel in accordance with this paragraph 1.3.4; provided that no such reference may be made more than seven Business Days after a Party has given notice to BSCCo that the query, difference or dispute has been referred to arbitration under Section H7;

(b) where such a question is referred to the Panel, any relevant arbitration proceedings or proceedings of the Trading Disputes Committee shall be suspended pending determination of the question by the Panel.

1.4 Duties of BSC Agents

1.4.1 Section U sets out the circumstances in which a BSC Agent may correct a Settlement Error without the application of the procedures in this Section W relating to Trading Disputes.

1.4.2 Except as is referred to in paragraph 1.4.1, each BSC Agent shall notify BSCCo promptly if it becomes aware of any matter which would or might reasonably be expected to give rise to a Trading Dispute.

1.4.3 For the avoidance of doubt, the provisions of this Section W in relation to the resolution of Trading Disputes and the rectification (or otherwise) of Settlement Errors following such resolution are without prejudice to the rights and obligations of BSCCo and BSC Agents under the BSC Agent Contracts.

1.5 Duties of BSCCo

1.5.1 If BSCCo is informed by a BSC Agent pursuant to paragraph 1.4.2 or otherwise becomes aware of any matters which would or might reasonably be expected to give rise to a Trading Dispute, it shall:

(a) notify each affected Trading Party and the NETSO; and

(b) raise a Trading Dispute in respect thereof in accordance with paragraph 3.2.

1.5.2 For the avoidance of doubt, the requirements of paragraph 1.5.1 shall not apply:

(a) in relation to a Settlement Error in respect of which a relevant Trading Dispute has already been raised; or

(b) in relation to an affected Settlement Period, after the Dispute Deadline pursuant to paragraph 3.2.2(a).

1.5.3 Where BSCCo becomes aware of any matters which would or might reasonably be expected to give rise to a Trading Dispute under paragraph 1.5.1 then it shall also notify a CfD Counterparty and the CM Settlement Body and include in that notice:

(a) the MSID(s) (if known) relating to the applicable SVA Metering System(s) or CVA Metering System(s) impacted by that matter; and

(b) the nature of the error.

1.6 Duties of Parties

1.6.1 Each Party shall:

(a) provide, and shall procure that any Party Agent appointed by it shall provide, to BSCCo or the Disputes Secretary, in accordance with the relevant BSC Procedure(s), such data, reports and other information as may reasonably be required:

(i) by BSCCo, to enable it to assess any Trading Dispute referred to it; or

(ii) by the Trading Disputes Committee, for the purposes of fulfilling its functions set out in this Section W; and

(b) otherwise co-operate (and shall procure that its Party Agents co-operate) with BSCCo, the Disputes Secretary, the Disputes Trading Committee and relevant BSC Agent with a view to the resolution of any Trading Dispute as quickly, efficiently and accurately as reasonably possible.

1.6.2 A Party shall be entitled to withhold documentation requested from it or its Party Agent in accordance with the provisions of Section H4.10.1.

1.6.3 Each Party (including for the avoidance of doubt the NETSO in relation to matters subject to Section Q) shall take, and shall procure that its Party Agents take, such steps as are necessary or requisite to correct or give effect to the correction (in any Settlement Run or otherwise) of a Settlement Error:

(a) in accordance with the instructions of BSCCo (in accordance with paragraph 3.2.7(d)) in relation to a Trading Dispute; or

(b) in accordance with any decision of the Trading Disputes Committee or the Panel pursuant to paragraph 3 or 4 in relation to a Trading Dispute.

3.3.1A BSCCo shall prepare a report of its findings pursuant to paragraph 3.2.7(b) (and where appropriate pursuant to paragraph 3.2.7(a)) and submit such report to the Trading Disputes Committee at its next meeting.

ANNEX X-2: TECHNICAL GLOSSARY

1. GENERAL

1.1 Introduction

1.1.1 This Annex to Section X sets out:

(a) technical definitions and acronyms applicable in the Code other than in relation to Section S;

(b) technical definitions and acronyms applicable only in relation to Section S;

(c) conventions applicable to the Code, including timing conventions, the use of superscripts/subscripts with variables, summations and mathematical operators; and

(d) the method of interpolation of variables.

1.2 Use of Mathematical Operators

1.2.1 The mathematical operators and conventions employed in the formulae and other algebraic expressions contained in the Code shall be construed in accordance with the following:

(a) the symbol * requires multiplication to be effected;

(b) in respect of any data items, the symbol ∈ refers to belonging to or falling within. For example a∈p denotes those Energy Accounts 'a' that belong to Party ‘p’, and j∈D denotes those Settlement Periods ‘j’ falling within Settlement Day ‘D’;

(d) the convention |FUNC| refers to the absolute value of the expression ‘FUNC’, that is the positive value whether the value obtained is positive or negative;

(e) Where in the Code the minimum value ('min') of a set of numbers is to be selected, then for the avoidance of doubt, the value selected shall be the negative number in that set with the greatest magnitude, or in the absence of any such negative number, the positive number in that set with the lowest magnitude. Where in the Code the maximum value ('max') of a set of numbers is to be selected, then for the avoidance of doubt, the value selected shall be the positive number in that set with the greatest magnitude, or in the absence of any such positive number, the negative number in that set with the lowest magnitude.

2. TECHNICAL TERMS AND INTERPRETATION APPLYING EXCEPT IN RELATION TO SECTION S

2.1 Introduction

2.1.1 Unless the context otherwise requires the provisions of this paragraph 2 as to the use, interpretation or definition of terms, expressions, acronyms, and subscripts and summations shall apply in relation to the Code except in Section S.

2.2 Use of Subscripts and Other Expressions

2.2.1 The subscripts and superscripts employed in the formulae and other algebraic expressions contained in the Code shall bear the respective meanings set out in Table X-1.

2.3 Glossary of Terms

2.3.1 Unless the context otherwise requires, and subject as provided in Table X-2, in the Code the words, expressions and acronyms set out in Table X-2 shall bear the respective meanings therein set out.

2.3.2 Table X-3 sets out for convenience the acronyms employed in the formulae and other algebraic expressions contained in the Code in alphabetical order of acronym name.

2.4 Sign Convention - Active Energy and Active Power

2.4.1 Subject to paragraph 2.4.2, the sign convention adopted in the Code is that all variables representing Active Energy or Active Power are:

(a) positive in any Settlement Period for which they represent Active Energy or Active Power delivered on to the Total System or (at any Systems Connection Points(s)) the Transmission System; and

(b) negative in any Settlement Period for which they represent Active Energy or Active Power off-taken from the Total System or (at any Systems Connection Points(s)) the Transmission System.

2.4.2 Paragraph 2.4.1 shall not apply in relation to:

(a) GSP Group Take;

(b) Offer Non-Delivery Volume, Period BM Unit Non-Delivery Offer Volume and any other variable representing Active Energy or Active Power derived by calculation undertaken pursuant to Section T,

which shall, for the avoidance of doubt, be positive, negative or zero as determined in accordance with the algebraic determination of such variable pursuant to the Code.

2.5 Sign Convention - Cashflows

2.5.1 The sign convention adopted in the Code in relation to amounts payable in respect of Trading Charges is explained in Section T1.2.3 and T1.2.4.

2.6 Use of Summations

2.6.1 Variables being summated are indicated by the use of the indices placed in preceding or following superscript or subscript position on the summation sign Σ, for example:

(a) Σ^c FUNC^c means the sum of the values of FUNC^c over all values of c.

(b) Σ_d FUNC_d means a sum of the values of FUNC_d over all values of d.

(d) Σ_d_∈_RFUNC_d means a sum of the values of FUNC_d over values of d belonging to the set R.

2.6.2 In some instances, where the summation over a particular variable is restricted to a subset of the possible values of such a variable as in paragraph 2.6.1(d), instead adopting of the convention in that paragraph, an equivalent result is achieved by limiting the summation in context, for example:

"Σ_dFUNC_d;

Where Σ_d represents a sum over all values of d belonging to the set R."

This is equivalent to Σ_d_∈_RFUNC_d.

2.6.3 In some instances, for convenience certain summations deviate from the above conventions and are further defined in context, for example:

"Σ_dFUNC_d;

Where Σ_d represents a sum over all values of d belonging to the set R."

Again, this is equivalent to Σ_d_∈_RFUNC_d.

3. TECHNICAL TERMS AND INTERPRETATION APPLYING IN RELATION TO SECTION S

3.6.1 In Section S of the Code, unless the context otherwise requires, whenever linear interpolation is referred to, the procedures set out in paragraphs 3.6.2 to 3.6.4 shall be followed.

3.6.2 Where the relationship between two variables, x and y, is defined only for a set of related pairs of spot values, (x₁, y₁), (x₂, y₂) ... (x_n, y_n), and where a value for y, y_i, is to be calculated by linear interpolation for a value of x, x_i, which is not a spot value contained in the set of related pairs, but which lies within the range of x spanned by the set of related pairs, the following formula shall be applied:

y_i = y₀ + ((y₁ - y₀) * (x_i - x₀)/(x₁ - x₀))

where x₀ refers to the value of x in that related pair in the set of related pairs in which x is less than x_i, and where the x of the related pair is the closest x to x_i;

3.7.2 BM Unit Allocated Demand Volume shall be positive in any Settlement Period for which it represents Active Energy offtaken from the Total System and negative in any Settlement Period for which it represents Active Energy delivered to the Total System.

4. TIMING CONVENTIONS

4.1 Introduction

4.1.1 A number of variables within the Code are expressed as differing functions of time. This paragraph 4 defines the nomenclature used in such expressions.

4.1.2 Paragraphs 4.1 to 4.3 apply in relation to the Code including Section S but paragraphs 4.4 to 4.6 do not apply in relation to Section S.

4.2 Spot Time

4.2.1 Many input variables and calculated values are given for spot times within the Code.

4.2.2 Spot times are an instant in time, and have no duration.

4.3 Settlement Period Times

4.3.1 Settlement Period j starts at the spot time occurring at the beginning of the half hour and ends at the spot time occurring exactly thirty minutes later. The spot time at the beginning of one period therefore coincides with the spot time at the end of the previous period.

4.3.2 For the avoidance of doubt the first Settlement Period of a Settlement Day begins at the spot time 00:00 on the current Settlement Day (D), and ends at the spot time of 00:30 for the current Settlement Day D.

4.3A Quarter Hour Times

4.3A.1 Quarter Hours start at the spot time occurring at the beginning of the quarter hour and ends at the spot time occurring exactly fifteen minutes later. The spot time at the beginning of one Quarter Hour period therefore coincides with the spot time at the end of the previous Quarter Hour period.

4.4 Point Variables

4.4.1 Where variables are determined in relation to spot times, they are termed ‘point’ variables. The values of point variables and their associated spot times are converted (as provided in Section T3.1) from data provided by the NETSO in a different format. There is a restriction on the resolution of the pre-conversion data, such that values of point variables to which this data is converted may only be for spot times expressed in a whole number of minutes.

4.4.2 Point variables are given the subscript 't', where 't' denotes the spot time to which the point variable applies. As point variables must be submitted in a whole number of minutes, there are 31 spot times for which point data may be submitted for any Settlement Period. Up to two point variables may be submitted for a single spot time. This is to accommodate step changes in the associated variable. As the first and last spot times for any Settlement Period coincide with the adjoining Settlement Periods, only one value may be submitted for these spot times. Thus for example for the period 12:30 – 13:00, only one value of point FPN may be submitted for spot times 12:30 and 13:00 (and up to 2 values for any other spot time which is a whole number of minutes and falls within the Settlement Period).

4.4.3 Whether or not step changes are expected depends upon the variable in question. For example, as FPN Data may normally be expected to comply with dynamic parameters, step changes (especially for generation) might not normally be expected. However, a Party’s view of their operating level may change significantly from one Gate Closure to the next, and step changes may be expected at the start of a Settlement Period.

4.4.4 Where two point values are submitted for the same spot time, the Point Variable Identification Number (f) is used to determine the sequence of the two values (as explained further in paragraph 4.5.4).

4.4.5 An example of a set of Point FPN data for Settlement Period (e.g. 12:30 – 13:00) is as follows:

Spot time, t	Point ^fFPN_ijt (MW)
12:30	200
12:37	235
12:57	245
13:00	245

4.4.6 The use of the subscript j is retained to represent the fact that the spot values are being submitted for spot times that fall within a particular Settlement Period.

4.5 Interpolation of Values of Point Variables Between Spot Times Supplied

4.5.1 For certain spot variables it may be necessary to evaluate values applicable to any spot time within a Settlement Period from the discrete point variables supplied. These are:

Name	Acronym	Units	Calculated from point variable:
Acceptance Volume	qA^k_ij(t)	MW	^fqA^k_ijt
Accepted Bid Volume	qAB^kn_ij(t)	MW	^fqAB^kn_ijt
Accepted Bid-Offer Volume	qABO^kn_ij(t)	MW	^fqABO^kn_ijt
Accepted Offer Volume	qAO^kn_ij(t)	MW	^fqAO^kn_ijt
Bid-Offer Volume	qBOⁿ_ij(t)	MW	^fqBOⁿ_ijt
FPN	FPN_ij(t)	MW	^fFPN_ijt
Deemed Standard Product Shape	qDSP^J_ij(t)	MW	^fDSP^J_ijt

4.5.2 Point variables for a particular parameter are normally used to calculate an associated function that is defined for all spot times in a Settlement Period, or in the time interval between such Point Variables. Such associated functions are expressed as a function of time F(t) and are calculated by linear interpolation from the point variables.

4.5.3 Whenever linear interpolation is referred to, the procedures set out in paragraphs 4.5.4 shall be followed.

4.5.4 Where for the purposes of the Code, a function of time F(t) is to be established by linear interpolation from a set of related pairs of spot values with point identification numbers and associated spot times t (each being a whole number of minutes) the following interpretation shall apply:

(a) For a spot time t_i which is not a spot value contained in the set of related pairs, but which lies within the range of t spanned by the set of related pairs, the following formula shall be applied:

F(t_i) = ^HF_t0 + (^LF_t1 – ^HF_t0)*(t_i – t₀)/(t₁–t₀)

where

t₀refers to the value of t in that related pair in the set of related pairs in which t is less than t_i, and where the t of the related pair is the closest t to t_i.

t₁refers to the value of t in that related pair in the set of related pairs in which t is greater than t_i, and where the t of the related pair is the closest t to t_i.

^HF_t0refers to the value of ^fF_t related to t₀ with the highest value of f; and

^LF_t1 refers to the value of ^fF_t related to t₁ with the lowest value of f.

(b) For a spot time t_i that is a value of t referred to in a related pair where a single value of ^fF_t exists, the value of F(t_i) shall be set to ^fF_ti contained in that related pair.

(c) For a spot time t_i that is a value of t referred to in a related pair where two values of ^fF_t exist, the value of F(t_i) shall (subject to 4.6.1(a)) and 4.6.1(b)) below) remain undefined for that time t_i.

4.6 Evaluation of Period Variables from Supplied and Interpolated Spot Variables

4.6.1 Period Variables represent the integrated MWh value over the Settlement Period j. Period variables are evaluated as follows:

The value of the Period Variable F_j for Settlement Period j, is determined by integrating the associated function of time F(t) with respect to time across the Settlement Period.

(a) Where the spot time t_i is the first spot time of the Settlement Period, the value of F(t_i) shall be set to the value of ^HF_ti for the purposes of evaluating the integral.

(b) Where the spot time t_i is the last spot time of the Settlement Period, the value of F(t_i) shall be set to the value of ^LF_ti for the purposes of evaluating the integral.

(c) Where for one or more spot time(s) (t₁, t₂ … t_n) falling within the Settlement Period, the value of F(t_i) remains undefined because two values of ^fF_ti exist for those spot times, and the spot times are neither the first nor last spot times in the Settlement Period, the integral will be evaluated pursuant to 4.6.2.

4.6.2 The integral shall be evaluated as the sum of:

(a) the integral for the period from the first spot time of the Settlement Period to the spot time immediately preceding the first such spot time; plus

(b) the integral from the spot time immediately succeeding the last such spot time to the last spot time of the Settlement Period; plus

(c) the integrals for each of the other periods within the Settlement Period, if any, defined by the interval between the spot time immediately succeeding any such spot time and the spot time immediately preceding the next such spot time.

4.1.1 The total aggregate liability of the Performance Assurance Board, each member of such board and the Performance Assurance Administrator to an Interested Person whether in contract, tort (including negligence or breach of statutory duty) or otherwise arising directly or indirectly out of or in connection with the performance or non-performance of its functions (including the contents of any opinion or report prepared by the Performance Assurance Board or the Performance Assurance Administrator) shall in no circumstances exceed one million pounds sterling (£1,000,000) per claim or series of related claims.

4.1.2 Neither the Performance Assurance Board nor any member of such board nor the Performance Assurance Administrator shall be liable to any Interested Person for any loss of profit, loss of revenue, loss of contract, loss of goodwill or any indirect or consequential loss arising out of or in connection with the performance or non-performance of its functions.

4.2.3 The exclusions from and limitations of liability of the Performance Assurance Board and members thereof and the Performance Assurance Administrator under this Section Z are reasonable because of (amongst other matters) the likelihood that the amount of damages awardable to the Interested Person from the Performance Assurance Board or a member thereof or the Performance Assurance Administrator would otherwise be disproportionate to the charges which it makes in connection with the performance of its functions and because of the limited resources and expertise of the Performance Assurance Board and the Performance Assurance Administrator.

4.2.4 The exclusions from and limitations of liability of the Performance Assurance Board, each member of such board and the Performance Assurance Administrator under this Section Z shall be considered severally and the invalidity or unenforceability of any one paragraph shall not affect the validity or enforceability of any other paragraph.

5 PERFORMANCE ASSURANCE PROCEDURES

5.1 Settlement Risks, Performance Assurance Parties, SVA Performance Assurance Objectives and Annual Performance Assurance Timetable

5.1.1 For the purposes of the Code:

(a) a "Settlement Risk" is a risk of any failure or error in a step or process required under the Code (including in each case a risk which has materialised as an actual failure or an error) for the purpose of effecting Settlement or otherwise required in connection with Settlement in accordance with the provisions of the Code;

(b) references to the significance of a Settlement Risk are to be construed in terms of both the probability of the failure or error (referred to in paragraph 5.1.1(a)) and its impact on Settlement;

(c) a "Performance Assurance Party" is a Supplier, Virtual Lead Party, CVA Meter Operator Agent, Data Collector, Data Aggregator, Meter Administrator, Licensed Distribution System Operator, Exempt Supply Notification Agent and/or a Registrant.

(d) a Settlement Risk is "material" to a Performance Assurance Party where:

(i) there is a risk that the Performance Assurance Party may, by failing (in whole or part) to perform any obligation under the Code or any Code Subsidiary Document, cause or contribute to the occurrence of such Settlement Risk; and

(ii) the significance of the Settlement Risk is of a level which the Performance Assurance Board determines (in its opinion) to be material; and

(e) a "within-period revision" means a revision by the Performance Assurance Board of:

(i) the Risk Evaluation Methodology;

(ii) the Risk Evaluation Register; or

(iii) the Risk Operating Plan,

as applicable in relation to a Performance Assurance Operating Period after such methodology, register or plan has been adopted for such Performance Assurance Operating Period;

5.1.1A Until the Retail Code Consolidation Date, each SVA Meter Operator Agent shall continue as a Performance Assurance Party notwithstanding the implementation of the Retail Energy Code performance assurance framework. For the avoidance of doubt, upon the Retail Code Consolidation Date, each SVA Meter Operator Agent shall cease to be a Performance Assurance Party and consequently, in respect of SVA Meter Operator Agents only, the functions, duties, responsibilities and (where relevant) powers of each Performance Assurance Party, the Panel, the Performance Assurance Board, BSCCo and the Performance Assurance Administrator shall cease to have effect.

5.1.1B The Performance Assurance Board and BSCCo may make representations in relation to the timing and implementation of the Retail Code Consolidation Date.

5.1.2 A Settlement Risk may be material to a Performance Assurance Party by reason of factors or circumstances:

(a) relating to Performance Assurance Parties of a class to which the Performance Assurance Party belongs ("class materiality"); or

(b) relating to the Performance Assurance Party individually ("individual materiality").

5.1.3 All Settlement Risks which affect Central Volume Allocation shall be deemed to be significant in terms of both probability of failure and impact on Settlement.

5.1.4 In the context of Supplier Volume Allocation:

(a) the Performance Assurance Board when performing the PAB Functions under this Section Z; and

(b) the Panel when approving the Risk Evaluation Register pursuant to paragraph 5.5.4, approving the Risk Operating Plan pursuant to paragraph 5.6.3 or hearing Risk Management Determination Appeals pursuant to paragraph 6.3,

shall have regard to the following (so far as consistent with the provisions of the Code) save where to do so would, in the opinion of the Performance Assurance Board or Panel as applicable, substantially prejudice the interests of all Performance Assurance Parties collectively or a class of Performance Assurance Parties collectively:

(i) the efficient, equitable and accurate allocation of energy between Suppliers resulting from the aggregated consumption of Metering Systems for which each Supplier is responsible; and

(ii) the efficient, accurate and co-ordinated transfer of Metering Systems data by Performance Assurance Parties between Suppliers and Supplier Agents.

5.2 Annual Performance Assurance Timetable

5.2.1 The Panel shall establish and may from time to time revise an annual timetable ("Annual Performance Assurance Timetable") for the carrying out in relation to each Performance Assurance Operating Period of the procedures in paragraphs 5.4 to 5.6.

5.2.2 The Annual Performance Assurance Timetable shall be published on the BSC Website.

5.3 Performance Assurance Techniques

5.3.1 The Panel shall prepare, and may from time to time amend, a list setting out those provisions of the Code, and/or processes established pursuant to provisions of the Code, which the Panel considers can mitigate (by detecting or preventing the occurrence, or correcting the effects, of) Settlement Risks.

5.3.2 For the purposes of the Code a "Performance Assurance Technique" is the implementation of any provision or process for the time being set out in the list established by the Panel under paragraph 5.3.1.

5.3.3 The list of Performance Assurance Techniques (and any amendments to such list) shall be published on the BSC Website.

5.4 Risk Evaluation Methodology

5.4.3 The Performance Assurance Board shall, in accordance with the Annual Performance Assurance Timetable:

(a) submit a draft of the proposed Risk Evaluation Methodology to all Performance Assurance Parties and other interested persons;

(b) after considering comments received from Performance Assurance Parties and other interested persons, make such changes (if any) to the proposed Risk Evaluation Methodology which are (in its opinion) appropriate; and

and (subject to paragraph 5.6A.2) references to the Risk Evaluation Methodology are to such methodology as so approved and adopted or revised by the Performance Assurance Board pursuant to paragraph 5.4.5.

5.4.4 The Performance Assurance Board shall publish the Risk Evaluation Methodology (and any within-period revision of it) on the BSC Website.

5.4.5 The procedures in paragraph 5.4.3 shall apply in relation to a proposed within-period revision of the Risk Evaluation Methodology, except that if the Performance Assurance Board considers that the revision is not significant it need not provide a draft of the proposed revised Risk Evaluation Methodology to Performance Assurance Parties and other interested persons.

5.5 Risk Evaluation Register

5.5.1 The Performance Assurance Board shall:

(a) identify and evaluate risks which are Settlement Risks, by applying the Risk Evaluation Methodology; and

(b) prepare and maintain a document (the "Risk Evaluation Register") setting out Settlement Risks, and the significance of each such Settlement Risk.

5.5.2 The Risk Evaluation Register will identify and evaluate Settlement Risks generically (and/or by references to classes of Performance Assurance Party) rather than by reference to particular Performance Assurance Parties.

5.5.3 The Performance Assurance Board shall establish the initial Risk Evaluation Register, and thereafter review and update the Risk Evaluation Register, in accordance with paragraph 5.5.4; and may on an ad-hoc basis revise the Risk Evaluation Register in accordance with paragraph 5.5.5.

(d) adopt the Risk Evaluation Register as so changed and approved by the Panel,

and (subject to paragraph 5.6A.2) references to the Risk Evaluation Register are to such register as so approved and adopted or revised pursuant to paragraph 5.5.5.

5.5.5 Where the Performance Assurance Board proposes a within-period revision of the Risk Evaluation.

(a) identifies a further Settlement Risk or changes its definition or evaluation of an existing Settlement Risk, the approval of the Panel shall not be required for such within-period revisions, and, subject to paragraph (b), the Performance Assurance Board shall;

(i) submit a draft of the proposed Risk Evaluation Register to all Performance Assurance Parties and other interested persons;

(ii) after considering comments received from Performance Assurance Parties and other interested persons, make such changes (if any) to the proposed Risk Evaluation Register which are (in its opinion) appropriate; and

(iii) approve and adopt the Risk Evaluation Register; and

(b) if the Performance Assurance Board considers that the revision is not significant it need not provide a draft of the proposed Risk Evaluation Register to Performance Assurance Parties and other interested persons.

5.5.6 Not used.

5.5.7 The Performance Assurance Board shall publish the Risk Evaluation Register (and any within-period revision of it) on the BSC Website.

5.6 Risk Operating Plan

5.6.1 The Performance Assurance Board shall:

(a) determine what Performance Assurance Technique(s) it considers should be applied in relation to each Settlement Risk identified in the Risk Evaluation Register; and

(b) prepare a plan (the "Risk Operating Plan") setting out:

(i) such Settlement Risks and the Performance Assurance Technique(s) that it has determined should be applied to each such Settlement Risk; and

(ii) the estimated overall cost to BSCCo of implementing such Performance Assurance Technique(s) in the current Performance Assurance Operating Period.

5.6.2 The Performance Assurance Board shall establish the initial Risk Operating Plan, and thereafter review and update the Risk Operating Plan, in accordance with paragraph 5.6.3 and may on a within-period basis review and update the Risk Operating Plan in accordance with paragraph 5.6.4.
