Reference is made to the Balancing and Settlement Code and, in particular, to the definition of “BSC Procedure” in Section X, Annex X-1 thereof.
This is BSC Procedure 14, Version 9.0 relating to the processing of Manifest Error Claims.
This BSC Procedure is effective from 29 June 2023.
This BSC Procedure has been approved by the Panel.

1 Introduction

1.1 Purpose and Scope of the Procedure

This Procedure describes the steps to be taken in order to process a Manifest Error claim, from the initial raising of such a claim by the Lead Party of an affected BM Unit or the National Electricity Transmission System Operator (NETSO), to the final settlement of any payments in relation to the claim.

1.2 Main Users of the Procedure and their Responsibilities

The main users of this procedure are:

(a) Trading Parties

(b) The NETSO

(d) The BSC Panel (or Panel Committee)² and its secretariat

(e) The Balancing Mechanism Reporting Agent (BMRA)

(f) The Settlement Administration Agent (SAA)

(g) The Funds Administration Agent (FAA)

All of the above have a responsibility for fulfilling their obligations under the Balancing and Settlement Code (BSC), either directly or via other contractual arrangements with signatories to the BSC, in respect of ensuring adherence to the Manifest Error claims process.

1.3 Key Milestones

The key milestones in this procedure are as follows:

(a) Raising and Flagging of Manifest Error claims (claims to be raised within 4 hours of the relevant Bid/Offer Acceptance Time, and notifications of such claims to be made within specified timescales);

(b) Investigation and collation of evidence in respect of Manifest Error claims. Where possible presentation of this information to the Panel/Panel Committee for adjudication and determination of any replacement Bid/Offer prices should be in such time as to allow these prices to be replaced prior to the relevant Initial Settlement Run;

(c) Raising claims for payment of an error compensation amount (as defined under BSC Section Q7.6.2) in relation to Manifest Errors. This must be done within 5 WD of the adjudication made in respect of Manifest Errors as described in paragraph (b) above; and

(d) Effecting payments in relation to Manifest Error claims (e.g. of any error compensation amount and/or fees to be paid by the Raising Party).

1.4 Balancing and Settlement Code Provision

This BSCP should be read in conjunction with the Code. This BSCP has been produced in accordance with the provisions of the Code. In the event of an inconsistency between the provisions of this BSCP and the Code, the provisions of the Code shall prevail.

1.6 Overview of Manifest Error Treatment in the BSC

BSC Section Q7 states that a Manifest Error claim may be raised by the Lead Party of a BM Unit in relation to a single Bid-Offer Pair; or by the NETSO in relation to a single Bid-Offer Acceptance (and, therefore, may be in relation to more than one Bid-Offer Pair). Such a Manifest Error may arise if a Lead Party submits an erroneously priced Bid/Offer in relation to one of its BM Units, and this Bid/Offer is accepted; or, if the NETSO erroneously accepts a Bid/Offer.

A Lead Party may raise a Manifest Error claim by giving notice of such claim to the NETSO. Within 15 minutes of the claim being raised the NETSO notifies BSCCo and the BMRA (although in practice, the NETSO enters the data directly into the BMRA system).

The NETSO may raise a Manifest Error claim by giving notice of such claim to BSCCo (Cc: the affected Lead Party) and the BMRA.

The information placed on the BMRS in relation to the claim includes the identity of the BM Unit concerned, the relevant Settlement Period, and the Bid Price or Offer Price to which the claimed error relates.

Claims must be raised as soon as is reasonably practicable, but in any event within 4 hours of the relevant Bid-Offer Acceptance Time. It is the responsibility of the Raising Party to ensure that the claim is made within this 4-hour time limit. For the purposes of determining whether or not this 4-hour time constraint has been complied with, claims will be deemed to have been received at the time of sending of the relevant email/fax.

Parties raising a Manifest Error claim are required to pay a non-returnable fee of £5000 (or such other amount determined by the Panel under Section Q7.2.3 of the BSC). Where a claim is raised outside of the 4-hour time limit, the Raising Party will still be required to pay this fee.

Manifest Error claims are considered by the Panel (or a Committee appointed by the Panel) in accordance with Section Q7.4 of the BSC. The Panel (or Panel Committee) is responsible for determining whether a Manifest Error occurred, and (in consultation with the NETSO) the replacement price which should be substituted for both the Bid Price and the Offer Price of the erroneously accepted Bid-Offer Pair should the Manifest Error claim be upheld.

The affected Lead Party may also raise a claim for payment of an error compensation amount in relation to the Manifest Error. If such a claim is raised, the Panel (or Panel Committee)³ determines (broadly speaking):

in the case of an Offer that is the subject of a Manifest Error claim, whether the avoidable costs associated with the change in output arising from the physical response from the affected BM Unit exceeded the amount paid to the Lead Party by virtue of replacing the Offer Price with the replacement Offer Price; or
in the case of a Bid that is the subject of a Manifest Error claim, whether the avoidable costs associated with the change in output arising from the physical response from the affected BM Unit was less than the amount paid by the Lead Party by virtue of replacing the Bid Price with the replacement Bid Price;

and in each case what additional payments are to be made to the affected Lead Party to cover such difference.

In practice, error compensation payments that amount to less than £500 will not be processed.

In the case of a Manifest Error on the part of the NETSO, any error compensation amount payable to the Lead Party shall be recovered from the NETSO. In the case of a Manifest Error on the part of the Lead Party, the error compensation amount shall be recovered from each Trading Party (in accordance with its Party Daily Reallocation Proportions).

*State which applies

4.11 Format of BMRS NETSO Manifest Error Claim Notification

The following states the form of the text that the NETSO should enter as a free-text message into the BMRS System:

“A Manifest Error claim has been raised by the NETSO in relation to an accepted [Bid/Offer*] for BM Unit [insert BM Unit ID] for Settlement Period(s) [insert affected Settlement Period(s)] on [insert affected Settlement Day]. The affected [Bid/Offer*] price is [insert relevant price].”

*State which applies

4.12 Manifest Error Claim Fee

A fee of £5,000 (or the value determined by the Panel under Section Q7.2.3 of the BSC) shall be payable to BSCCo for all valid Manifest Error claims received by the DS. This fee, which shall not be reimbursed in any circumstances, shall be invoiced by BSCCo in accordance with Section Q7.4.3(g).

4.13 Withdrawing a Manifest Error Claim or Claim for Payment of Error Compensation Amount

Withdrawal/closure requests will only be accepted by the DS where these are made in writing by an Authorised Signatory²⁷ and the request is received prior to the claim being submitted to the TDC for consideration. Withdrawal requests do not impact on the fee payable under 4.12 above.

All withdrawal/closure requests for Manifest Error claims submitted to the DS will be reported to the TDC at its next scheduled meeting. The TDC may still wish to consider the Manifest Error claim.

4.14 Determining Replacement Prices for Utilisation in the Correction of Manifest Errors

In determining the replacement prices to be used in the processing of a Manifest Error, a number of steps need to be followed:

Step 1: Identify the acceptance quantities for which replacement Offers and/or Bids need to be determined.

Step 2: Identify the replacement Offers and Bids to use.

Step 3: Determine the weighted average replacement price.

The approach to be followed differs depending upon the circumstances of the Manifest Error. If, for example, the Acceptance associated with the Manifest Error was necessarily issued to a BM Unit with particular dynamic characteristics (for example because energy was needed in short timescales to control system frequency) then the detailed dynamics of possible replacement Offers and Bids should be given more consideration in the identification of possible replacement Offers and Bids. In other cases, a more approximate simplified approach should be adopted which it is intended will reduce the administrative burden of processing the Manifest Error. The flow diagram overleaf identifies the main steps involved.

Step 1: Identifying Acceptance Quantities for Replacement

Under the BSC, a particular Acceptance may result in the acceptance of one or more Bids and/or Offers. Furthermore, depending upon the nature of any Manifest Error, one or more of the Bids and/or Offers accepted as a result of an Acceptance relating to the Manifest Error may form part of an Error Bid/Offer Pair.

Step 1a – Identification of Accepted Bid Volume and/or Accepted Offer Volume

In order to determine the appropriate replacement price for a particular Error Bid/Offer Pair, the quantity of accepted Offers and/or Bids that need to be “replaced” should first be determined. This quantity is initially determined as a power profile of the relevant Accepted Offer Volume and/or Accepted Bid Volume associated with each Error Bid/Offer Pair.

For more straightforward²⁸ Manifest Errors, the erroneous Accepted Offer Volume and/or Accepted Bid Volume associated with the Error Bid/Offer Pair may be determined simply as being equal to the Accepted Bid Volume and/or Accepted Offer Volume for each Error Bid/Offer Pair associated with the relevant Acceptance. There are, however, a number of more complex situations that may arise in which the determination of these quantities is less straightforward. The more complex scenarios considered in this procedure are as follows:

1) Two Acceptances, each resulting in the acceptance of a particular Bid-Offer Pair. One Acceptance being entirely erroneous, the other entirely correct;

2) Two Acceptances each resulting in the acceptance of a particular Bid-Offer Pair, both Acceptances being erroneous;

3) A single Acceptance accepting both one Bid-Offer Pair correctly and a different Bid-Offer Pair in the same Settlement Period erroneously;

4) A single Acceptance accepting the same part (i.e. Offer part or Bid Part) of a single Bid-Offer Pair, partly correctly and partly erroneously.

5) A single Acceptance accepting part of the Offer of a Bid-Offer Pair correctly, and part of the Bid incorrectly.

The approach to be adopted in each of these cases is discussed in turn below:

1) In the first case, Section Q7.5.2(a)(ii) of the BSC implies that the “correct” acceptance should be disregarded for the purposes of the determination of the replacement quantities. This is because Q7.5.2(a)(ii) refers effectively only to the identification of other Bid/Offer Pairs which would have been accepted by the NETSO if it had not accepted (by the relevant Acceptance). Hence, for example, if Acceptance k erroneously accepts 5 units of Bid-Offer Pair n, and Acceptance m correctly accepts 6 units of Bid-Offer Pair n, the quantity of replacement Offers or Bids is 5 units.

2) In the case where two Manifest Errors affect a single Bid-Offer Pair, the application of the rules in the BSC would appear to be ambiguous. It is not clear whether based on a strict reading of the BSC, the replacement price to be used should be based on the first or second Manifest Error.

3) In case 3, those quantities of other Bid-Offer Pairs correctly accepted by an Acceptance, which has also erroneously accepted part of a different Bid-Offer Pair, may be disregarded for the purposes of processing the Manifest Error claim. Q7.5.2(a)(ii) includes the words: “…if it had not accepted (by the relevant Acceptance) the Error Bid/Offer Pair”. This only requires consideration of the acceptance insofar as it relates to of the Error Bid Offer Pair(s), and not to other Bid-Offer Pairs.

4) In case, 4, it is assumed that a single Acceptance has both correctly accepted part of a particular Offer (or Bid) and erroneously accepted part of the same Offer (or Bid). For example this may arise if the NETSO wished to accept an Offer for 10 minutes, but in practice did so for 20. In this case, because the entire Bid-Offer Pair is an Error Bid-Offer Pair, then again from Q7.5.2(a)(ii), it would be appropriate to determine a replacement price taking into account the entire quantity of accepted Offer (or Bid) from that Bid-Offer Pair (i.e. including that part of the Offer (or Bid) that was correctly accepted).

5) In case 5, it is assumed that a single Acceptance results in the erroneous Acceptance of an Offer from a particular Bid-Offer Pair, and partly in the correct Acceptance of a Bid from the same Bid-Offer Pair. Given that both the Bid and the Offer form part of the Bid-Offer Pair, this case is very similar to case 4 and based upon the an interpretation of the existing BSC rules, the correctly accepted Bid (or Offer) quantity would be taken into account in determining the replacement price.

Whilst some consideration has been given to ensuring the above list covers the set of possible scenarios, it is possible that there may be other scenarios that may arise that have not been identified. To the extent that this is the case, then it would be necessary to determine the replacement quantities based upon consideration of the detailed circumstances of each particular case.

Step 1b – Conversion of Accepted Bid Volume and/or Accepted Offer Volume into MWh replacement quantity

The approach used in determining the replacement price should, by default, but not in all cases, adopt a simplified approach in order to assist in the determination of the alternative Bids and Offers that were “available” to the NETSO. Under the simplified approach the Accepted Bid Volumes and Accepted Offer Volumes associated with a particular Error Bid/Offer Pair would be integrated over the Settlement Period in order to determine a single MWh new error quantity.

This simplified approach should not be adopted where spot MW values that adequately represent the system requirements at the time of the erroneous Bid-Offer Acceptance could not have been met by the BM Unit(s) indicated by the simplified approach.

Step 2: Identifying Replacement Bids and Offers

In determining the replacement Offer and Bids available to the NETSO, the following process should be followed:

If Step 1b) above has been followed then:

Step 2a) - convert the MWh quantity of energy determined under Step 1b) to a power equivalent (by dividing by ½ an hour).

Step 2b) - based on a subset of dynamic and other data (specifically, only MIL, MEL, run-up and run-down rates, Notice to Deviate from Zero, Notice to Deliver Offers/Bids and FPN - taking into account other acceptances), identify the quantity of power that could have been delivered by other Offers (or, if the power value is negative, then Bids) at the end of each relevant Settlement Period, assuming that the acceptance was issued at the Bid-Offer Acceptance time of the Acceptance associated with the Manifest Error. This delivers a list of alternative Offers or Bids from other BM Units, and the quantity of replacement MW available at the end of each relevant Settlement Period.

Step 2c) - identify which of the replacement Offers or Bids would have been chosen in accordance with Q7.5.2(a)(ii). In following this step, it is proposed that unless the Panel (in consultation with the NETSO) reasonably believes that (i) some or all of those Offer or Bids would not have been chosen, (ii) certain quantities of other Offer or Bids would have been chosen, or (iii) the aggregate quantity of the replacement Offers or Bids determined at the end of the Settlement Period does not reasonably reflect the quantity required to be determined, then Bids and Offers would be selected from those determined to be available in price merit order. This means that for Offers, the cheapest would be selected such that the aggregate MW quantity of Offers is equal to the MW quantity of the Manifest Error identified in Step 2a. In the case of Bids, the most expensive Bids are identified. If any of the criteria (i-iii) are met, then the Panel (in consultation with the NETSO) will determine the quantities of those Offers and Bids that are available, and/or the replacement quantity to be selected.

If Step 1b) above has not been followed then:

Step 2d) - Identify which of the replacement Offers or Bids would have been chosen in accordance with Q7.5.2(a)(ii).

It is recognised that this is a subjective process that will require detailed consideration of the exact nature of the particular Manifest Error in question. It is noted that it may not always be appropriate to identify replacement MW to match the entire power profile identified in Step 1a), and indeed in some cases the exact power profile may be exceeded.

It is not considered practicable to further document the selection process at this stage. Instead, it is envisaged that a “case law” approach to selection of replacement prices in such circumstances should be permitted to emerge.

Step 3: Determining Replacement Prices

Determine the replacement price based upon the MW (or MWh) weighted average of the replacement Offers or Bids available identified.

Simplified Example

The following example is included to further explain the approach proposed if Step 1b) is taken. The following diagram shows the power profile of a Manifest Error relative to FPN over two Settlement Periods.

The erroneous acceptance results in the acceptance of both Bids and Offers in each Settlement Period. There is a net overall quantity of accepted Offers in SP1 and of Bids in SP2. For the purposes of this example, these are assumed to be +10MWh and –5MWh respectively.

These net energy quantities are converted to a power value equivalent of +20MW and –10MW for Settlement Periods SP1 and SP2 respectively.

For SP1, a list of potentially available Offers is constructed, identifying the quantity of additional power (arising from a reduction in demand or increase in generation) that BM Units participating in the balancing mechanism could deliver. In constructing this list a subset of dynamic and other data is used (as described above). For the purposes of this example, the following replacement Offers are assumed to be available:

BM Unit Power Level Price £/MWh

BMU1 8MW 5MW@ £20/MWh, 3MW@ £50/MWh

BMU2 50MW £25/MWh

BMU3 10MW £30/MWh

etc.

The NETSO further identifies that BMU2 was not available because it was operating behind an export constraint. Hence, the replacement Offers selected are as follows:

5MW from BMU1 @ £20/MWh

5MW from BMU3 @ £30/MWh.

Hence, the MW weighted average replacement price is £25/MWh.

A similar exercise is conducted by selecting replacement Bids in SP2

1 The Disputes Secretary (as defined under BSCP11) shall undertake the obligations of BSCCo and the Panel Secretary as referred to in BSC Section Q7, and shall be responsible for liaison with the relevant secretariat function in respect of 1.2(d) above.

2 The BSC Panel, in accordance with BSC Section Q 7.4.2, may appoint a Panel Committee to discharge its functions in respect of Manifest Errors. At its meeting of 22 March 2001 the BSC Panel delegated authority for adjudication of Manifest Error claims and determination of replacement Bid/Offer Prices to the Trading Disputes Committee, with effect from NETA Go-live.

3 At its meeting of 3 May 2001 the BSC Panel delegated authority to the Trading Disputes Committee to determine the error compensation amount in respect of Manifest Error claims.

4 The Manifest Error claim relates to a particular Bid-Offer Pair

5 The NETSO will invalidate all claims raised to it which are outside the timescales defined in 3.1.1. For the avoidance of doubt, BSCCo should still be notified of the claim and the Manifest Error claiming fee will still be payable by the Raising Party. Where a BSC Party has a disagreement with the NETSO over these timescales, then that BSC Party shall immediately raise a Query to the DS in accordance with BSCP11.

6 In the event of the BMRS being down, where a claim for Manifest Error is made within office hours, the NETSO shall request that Elexon send out a circular notifying participants of such a claim. Where a claim is made outside of office hours, the NETSO will not be deemed to be in breach of 3.1.4.

7 The DS will invalidate all Manifest Error Claims raised to it by the NETSO which are outside the timescales defined in 3.2.1. For the avoidance of doubt the Manifest Error Raising Fee will still be payable by the NETSO.

8 The Manifest Error claim relates to a particular Bid-Offer Acceptance.

9 In the event of the BMRS being down, where a claim for Manifest Error is made within office hours, the NETSO shall request that Elexon send out a circular notifying participants of such claim. Where a Manifest Error claim is made outside of office hours, the NETSO will not be deemed to be in breach of 3.2.2.

10 This BSCP recognises that both the NETSO and the BSC (Lead) Party will operate on 24-hour timescales in accordance with Balancing Mechanism requirements but the DS will only operate on normal Working Day timescales. Therefore all actions on the DS begin from the first Working Day of receipt of a Manifest Error Claim Form.

11 At this point the DS will seek confirmation from the NETSO and/or the BSC (Lead) Party that all other obligations under 3.1 and 3.2 above have been met. Any breach of these obligations will be flagged to the TDC when it considers the Manifest Error claim.

12 Where either party has a disagreement regarding this determination then a Query shall be immediately raised to the DS in accordance with BSCP11.

13 Section 4.14 of this procedure provides details of the methodology to be adopted by the TDC in determining replacement prices.

14 Outcome of TDC decision and replacement prices to be detailed on both the Finding Forms and the ELEXON Circular.

15 Where it is not possible to include the results of the TDC decision in the Initial Settlement Run, a reason and statement as to when the decision will be implemented must be provided to the DS.

16 The Authorisations applicable to BSCP11 (i.e. those detailed under BSCP38) shall be used for the purposes of validating compensation claims.

17 The DS will take no further action where the DS finds that the compensation claim is invalid. Any disagreement over this determination shall be notified to the DS in writing.

18 The TDC may request additional information in accordance with Sections Q7.6.4(c) and G2.2.1(b) of the BSC.

19 The NETSO will only be notified where the Manifest Error was on the part of the NETSO.

20 Trading Parties will only be notified where the Manifest Error was on the part of the BSC (Lead) Party.

21 Error compensation payments that amount to less than £500 will not be processed.

22 A single Manifest Error claim must be made for each single Error Bid-Offer pair. If there is a need to raise Manifest Error claims for more than one Error Bid-Offer Pair, please use one form for each Error Bid-Offer Pair.

23 A single Manifest Error claim may be made for one or more Error Bid-Offer Pairs in a single Bid-Offer Acceptance. If there is a need to raise Manifest Error claims for more than one Bid-Offer Acceptance, please use one form for each Bid-Offer Acceptance.

24 The Affected BM Unit column will contain the BM Unit Id and NOT the NETSO BM Unit Name/Id or any other identifier

25Where it is not possible to include the results of the TDC decision in the Initial Settlement Run, a reason and statement as to when the decision will be implemented must be provided to the Disputes Secretary.

26 Interest will be applied to the sums above at BSCCo Bankers Base Rate for the period from the original payment date for settlement to the final date when settlement of such payment is made.

27 In accordance with the Authorisations applicable to BSCP11 (i.e. as detailed under BSCP38).
