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

for so long as the same person acts as both the BMRA and SAA, or both the BMRA and the ECVAA (as the case may be), the NETSO shall be treated as having sent such data to both of them if it has sent the data to one of them.

7. MANIFEST ERRORS

7.1 Meaning of Manifest Error

7.1.1 For the purposes of this Section Q:

(a) there is a "Manifest Error" in a Bid-Offer Pair or an Acceptance where and only where:

(i) in relation to a Bid-Offer Pair, there was a Manifest Error on the part of the Lead Party of a BM Unit in the Offer Price and/or the Bid Price associated with a Bid-Offer Pair relating to that BM Unit which has been accepted by the NETSO;

(ii) in relation to an Acceptance and one or more of the Bids or Offers thereby accepted, the acceptance of such Bid(s) or Offer(s) was a Manifest Error on the part of the NETSO;

(b) for the purposes of paragraph (a) an error will be considered manifest only where it is self-evidently an error;

(i) an "Error Bid-Offer Pair" is the Bid-Offer Pair referred to in paragraph (a)(i) or (as the case may be) a Bid-Offer Pair which included one of the accepted Bid(s) or Offer(s) referred to in paragraph (a)(ii);

(ii) the "relevant" Acceptance is the Acceptance by which the Error Bid-Offer Pair(s) were accepted, and references to the Bid-Offer Acceptance Time shall be construed accordingly;

(iii) the "relevant" Settlement Period is the Settlement Period to which the Error Bid-Offer Pair relates;

(iv) references to the Lead Party are to the Lead Party of the BM Unit for which the Error Bid-Offer Pair(s) were submitted.

7.2 Claiming Manifest Errors

7.2.1 Where a Party considers that it has made a Manifest Error in a Bid-Offer Pair, such Party may, subject to paragraph 7.2.3, as soon as reasonably practicable after becoming aware of the error and in any event no later than four hours after the Bid-Offer Acceptance Time, make a claim to that effect by giving notice of such claim to the NETSO, identifying the Error Bid-Offer Pair.

7.2.2 Where the NETSO considers that it has made a Manifest Error in an Acceptance, the NETSO may, subject to paragraph 7.2.3, as soon as reasonably practicable after becoming aware of the error and in any event no later than four hours after the Bid-Offer Acceptance Time, make a claim to that effect by giving notice of such claim to BSCCo, which notice the NETSO shall also copy promptly to the Lead Party, identifying:

(a) each Error Bid-Offer Pair; and

(b) the relevant Acceptance, by specifying:

(i) subject to paragraph (ii), the Bid-Offer Acceptance Number;

(ii) where (at the time at which the NETSO gives such notice) the Bid-Offer Acceptance Number is not available to the NETSO (or no such number has been established), the Acceptance Data specified in paragraphs 5.3.1 (a) and (c).

7.2.3 Where a Party makes a claim of Manifest Error, such Party shall pay a fee to BSCCo the amount of which (for each such claim) shall be five thousand pounds sterling (£5,000), or such other amount as the Panel may from time to time, after consultation with Parties, determine upon not less than thirty days notice to Parties; which fee shall not be reimbursed in any circumstances.

7.3 Flagging Manifest Errors

7.3.1 Where a Party gives notice of a claim of Manifest Error to the NETSO under paragraph 7.2.1, the NETSO shall within fifteen minutes after receiving such notice forward the notice to BSCCo.

7.3.2 At the same time as giving notice (under paragraph 7.2.2 or 7.3.1) of a claimed Manifest Error, the NETSO shall ensure that a Manifest Error notice is posted on the BMRS, specifying the identity of the BM Unit, the relevant Settlement Period(s) and the Bid Price or Offer Price to which the claimed error relates.

7.4 Determination of Manifest Errors

7.4.1 The Panel shall consider claims of Manifest Error in accordance with this paragraph 7.4.

7.4.2 For the avoidance of doubt the Panel may establish or appoint a Panel Committee to discharge its functions under this paragraph 7; and (notwithstanding Section W2.2) the Panel may appoint the Trading Disputes Committee, and (if so appointed) that Committee shall have the ability and competence, to do so.

7.5 Adjustments to Bid or Offer Price

7.5.1 Where the Panel determines that there was a Manifest Error, the Bid Price and Offer Price of each Error Bid-Offer Pair shall be adjusted (so that such Bid-Offer Pair shall be treated as if made at the adjusted Bid Price and Offer Price), for all purposes of Settlement, in accordance with paragraph 7.5.2.

7.5.2 For the purposes of paragraph 7.5.1:

(a) the Panel shall determine (in its opinion) in consultation with the :

(i) what other Bid-Offer Pairs (submitted by any Party) were available to, and not already accepted by, the NETSO at the Bid-Offer Acceptance Time;

(ii) which of those other Bid-Offer Pairs would (in the circumstances which gave rise to the NETSO accepting the Error Bid-Offer Pair(s), and having regard to the principles on which the NETSO generally selects Bid-Offer Pairs for acceptance) have been accepted by the NETSO, at the Bid-Offer Acceptance Time, if it had not accepted (by the relevant Acceptance) the Error Bid-Offer Pair;

(iii) the Bid Price or Offer Price of such Bid-Offer Pair (or where it determines that more than one would have been accepted, the average of such prices, weighted according to the quantities (in MWh) of each which would have been accepted)

(and for these purposes it shall be assumed that one or more of the Bid/Offer Pairs referred to in paragraph (a)(i) would have been so accepted);

(b) both the Bid Price and the Offer Price of the Error Bid-Offer Pair shall be adjusted to be equal to the price determined under paragraph (a)(iii);

A is the amount of the Avoidable Party Costs of the Lead Party in relation to the changes in Exports and/or Imports determined by the Panel under paragraph 7.6.3(a);

B is an amount determined as:

(MECQⁿ_ij * Pⁿ_ij);

where Pⁿ_ij is the adjusted Offer Price or Bid Price (being the same price, in accordance with paragraph 7.5.2(b)) of the Error Bid-Offer Pair in accordance with paragraph 7.5.1;

(b) the "error compensation volume" (MECQⁿ_ij) is the quantity (in MWh) determined by the Panel under paragraph 7.6.3(b), subject to paragraph (c);

(i) MECQⁿ_ij shall be negative where it represents an increase in net Imports or a reduction in net Exports, and otherwise positive;

(ii) the value of MECQⁿ_ij shall not exceed the algebraic sum of the Period Accepted Offer Volume and Period Accepted Bid Volume for all Acceptances relating to the Error Bid-Offer Pair;

(iii) the magnitude of MECQⁿ_ij shall not exceed the magnitude of the amount claimed by the Lead Party under paragraph 7.6.3(a).

7.6.3 Where the Lead Party submits a claim under paragraph 7.6.1, the Panel shall determine, in its opinion:

(a) what changes in Exports and/or Imports of the BM Unit during the relevant Settlement Period resulted from action taken by the Lead Party for the purposes of complying (in accordance with the Grid Code) with the relevant Acceptance; and

(ii) irrespective of the period of notice given of the Outage, the period (if any) of an Outage which falls more than two hours after the commencement of the Outage;

(b) a "relevant" Settlement Period is a Settlement Period for which Gate Closure fell within the outage compensation period.

8.1.2 For the avoidance of doubt, this paragraph 8 shall not apply by reason only of any Outage or other withdrawal, failure or breakdown of any system which does not affect the communication of Physical Notifications.

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

(b) for each Metered Volume Reallocation Notification(s) in force for any relevant BM Unit(s) provide:

(i) the MVRNA Authorisation under which it is given (thereby identifying the BM Unit, the Lead Party and relevant Subsidiary Party and the Subsidiary Energy Account to which it relates); and

(ii) for each relevant Settlement Period, the quantity of Active Energy and the percentage (either of which may be zero) of BM Unit Metered Volume allocated to each Subsidiary Energy Account in accordance with Section P3.3.

8.2.2 The Panel will not consider a claim by a Party for compensation under this paragraph 8.2 unless the Party's submission under paragraph 8.2.1 demonstrates (but without prejudice to what the Panel determines under paragraph 8.2.4), to the reasonable satisfaction of the Panel, that it and any relevant Subsidiary Party suffered such a loss as is referred to in paragraph 8.2.1(b).

8.2.3 For the purposes of this paragraph 8.2:

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).
