1 Introduction

1.1 Purpose and Scope of the Procedure

This BSC Procedure (BSCP) deals with the raising, resolution and rectification of all Trading Disputes, in accordance with Section W of the Balancing and Settlement Code (the Code). Where practicable, before invoking this procedure, all affected Parties are expected to use all reasonable endeavours to resolve any queries via internal investigation, involving their own Agents or BSC Agents where appropriate, in accordance with the provisions of the Code¹.

Where errors are identified in Credit Cover or a Party’s Credit Default status, this procedure, in association with the specific rules contained in Section M of the Code, will apply.

This BSC Procedure does not cover the Change of Supplier or Registration process or any other disputes resolved under the Retail Energy Code (REC) which do not impact on Settlement Data.

Subject to any arbitration proceedings, all Trading Disputes shall be raised and dealt with in accordance with Section W of the Code and this BSC Procedure. No Party may refer a Trading Dispute to arbitration unless the Trading Dispute has been raised, dealt with and decided in accordance with provisions of Section W of the Code and this BSC Procedure.

1.2 Main Users of Procedure and their Responsibilities

This BSCP should be used by:

BSC Parties (including the BSCCo) to raise and resolve Trading Disputes;

Trading Disputes Committee to determine matters relating to Trading Disputes;

Disputes Secretary (DS) to:

(a) Administer the process detailed in this BSC Procedure;

(b) Facilitate the processing of Trading Disputes and escalation of Trading Disputes to the TDC;

(d) Maintain a register of precedents established by the TDC.

All Parties (including the BSCCo and its Agents, BSC Parties and their Agents, the National Electricity Transmission System Operator (NETSO) and Distribution System Operators) to assist in the resolution of Trading Disputes and to effect the rectification of such Trading Disputes in the next available Settlement or Reconciliation Run or Extra-Settlement Determination if appropriate.

1.3 Data Retention Requirements for use in Settlement Runs and Extra-Settlement Determinations

BSC Parties and BSC Agents are required by the Section U of the Code to retain Settlement data to support the resolution of Trading Disputes:

a. up to at least 28 months after the relevant Settlement Day for use in a form in which the data can be requested and used in the carrying out of a Settlement Run or Volume Allocation Run; and

b. thereafter, until 40 months after the relevant Settlement Day in a form that may be retrieved, if requested, within 10 Working Days, for use in an Extra-Settlement Determination.

In addition, if requested by the Panel, BSC Parties and BSC Agents will be required to retain Settlement data beyond 40 months to support an Extra-Settlement Determination.

1.4 Information required on a BSCP11/01 Trading Dispute Form

A Trading Dispute will not be accepted or processed by the Disputes Secretary unless BSCP11/01 form is submitted, complete with the following information:

Raising Party contact details
All affected Settlement Periods (and Settlement Days) claimed. Where an end-date is not specified on the form, it will be assumed that the alleged Settlement Error is ongoing. If an end-date is provided but the Settlement Error extends beyond that date the TDC will amend the end-date to cover all affected Settlement Days.
Whether the Raising Party is claiming for exceptional circumstances (as described in section 2.2)
Details of the affected site/BM Unit
A description of the error (refer to the questionnaire in Form BSCP11/01)
An identified breach of the BSC or Code Subsidiary Document which has led to the alleged Settlement Error

In addition, the BSCP11/01 Trading Dispute Form must be authorised by a Category O authorised person. Please refer to BSCP38 for details on Authorisations.

1.5 Balancing and Settlement Code Provision

This BSCP must be read in conjunction with the Code and in particular Section W. 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 Associated BSC Procedures

The main BSCPs that interface with this BSCP are detailed below. This list is not exhaustive as the investigation and processing of a Trading Dispute may necessitate reference to a range of BSCPs.

BSCP38	Authorisations
BSCP509	Changes to Market Domain Data

1.7 EMR Requirements

Where BSCCo becomes aware of any matters which would or might reasonably be expected to give rise to a Trading Dispute, then it shall notify the CfD Counterparty and the CM Settlement Body, in accordance with 5.1, of:

The MSID relating to the applicable SVA or CVA Metering System (if known); and
The nature of the non-compliance.

1.8 Claims relating to the application of Non BM Unit ABSVD

It is recognised that the confidentiality requirements relating to Non BM Unit ABSVD may make it difficult for BSC Parties to know whether Non BM Unit ABSVD applied to their Energy Account was calculated correctly. Where a BSC Party is concerned that there may be an issue in relation to Non BM Unit ABSVD which would or might reasonably be expected to give rise to a Trading Dispute, they may notify BSCCo. Where BSCCo becomes aware (through this route, or otherwise) of any matters in relation to Non BM Unit ABSVD which would or might reasonably be expected to give rise to a Trading Dispute, the Disputes Secretary will investigate the alleged Settlement Error and will either:

Complete the BSCP11/01 Trading Dispute form on behalf of the Party; or

Inform the Party that there is no Settlement Error to resolve.

2 Timeliness Criteria

2.1 Dispute Deadline

Subject to section W1.2.6 of the Code, the Dispute Deadline in relation to an affected Settlement Period is:

Trading Dispute Type	Dispute Deadline
General Dispute Deadline	20^th Working Day following the day on which the relevant Settlement Run was carried out.
Trading Dispute relating to SVA Half Hourly data and processes (SVA Half Hourly Dispute)	70^th Working Day following the carrying out of the Final Reconciliation Run (RF)².
Trading Dispute relating to SVA Non Half Hourly data and processes (SVA Non Half Hourly Dispute)	70^th Working Day following the carrying out of the Final Reconciliation Run (RF).
Trading Dispute concerning data relating to profile coefficient.	3^rd Working Day following the Settlement Day in which the affected Settlement Period(s) occurred.
Trading Dispute relating to Market Domain Data.	2^nd Working Day following the Settlement Day in which the affected Settlement Period(s) occurred.

For the avoidance of doubt, subject to a determination of the Panel or an arbitration body in accordance with section W, the TDC will not consider whether a Settlement Error has occurred in respect of any affected Settlement Period which it does not consider has satisfied the relevant Dispute Deadline.

2.2 Exceptional circumstances

Subject to section W1.2.6 of the Code, if, in relation to a particular Trading Dispute, the TDC determines that there are exceptional circumstances as a result of which the applicable Dispute Deadline should not apply, it may waive the requirement that the Trading Dispute should be raised within the Dispute Deadline.

If the Raising Party wishes the TDC to consider whether there are exceptional circumstances in accordance with section W3.2.4 it shall attach a statement (together with supporting evidence), when completing Form BSCP11/01, of why it considers that exceptional circumstances exists.

Notwithstanding the above, if the TDC determines that there are exceptional circumstances, the Trading Dispute must still be raised no later than 20 months after the relevant Settlement Day in which the affected Settlement Period occurred or if later, where the alleged Settlement Error is an error in a Post-Final Settlement Run or an Extra-Settlement Determination, in accordance with W1.2.6.

6.10 Rectification of Trading Disputes

Following a decision of the TDC that a Trading Dispute was raised in a timely fashion, that a Settlement Error has occurred and that the materiality of the Trading Dispute is £3,000 or greater, the TDC shall determine the appropriate means of rectification. The methods of rectification available to the TDC will be dependent on whether the Final Reconciliation Settlement Run (RF) for the Disputed Settlement Days has been performed.

Where the Trading Dispute is capable of rectification before the relevant Final Reconciliation Settlement Run (RF), the TDC shall:

a) determine that the error should be corrected in the next Settlement Run relating to the relevant Settlement Day (see section 5.3); or

b) where the period to the next Timetabled Reconciliation Settlement Run (considered together with the materiality of the Trading Dispute) is such that the Trading Disputes Committee believes that an Extra Settlement Determination is justified, determine that an Extra-Settlement Determination should be carried out (see Appendix 6.11 and section 5.5).

Where a Trading Dispute is not capable of resolution until after the relevant Final Reconciliation Settlement Run (RF), the TDC shall:

a) determine that the error should not be corrected, having regard to all the circumstances (including the length of time which has elapsed since the occurrence of the event giving rise to the Trading Dispute); or

b) determine that an Extra-Settlement Determination and/or Post-Final Settlement Run should be undertaken (see section 5.4 or 5.5 as appropriate).

6.11 Extra-Settlement Determinations performed prior to the Final Reconciliation Run

The Code states that in certain circumstances the TDC may determine that a Trading Dispute should be rectified by performing an ESD prior to the Final Reconciliation Run. This would only be the case where the period to the next Timetabled Reconciliation Settlement Run (considered together with the materiality of the Trading Dispute) is such that the TDC believe an ESD is justified.

If an ESD is performed prior to the Final Reconciliation Run, all payments must be reversed (or unwound) on or as near as practicable to the Payment Date in respect of the Timetabled Reconciliation Settlement Run in which the Settlement Error is corrected. This is to prevent any double correction of an error through both an ESD and the Timetabled Reconciliation Settlement Run. Prior to the next Timetabled Reconciliation Settlement Run, each Trading Party affected by the initial payment shall be entitled to be paid by or liable to pay to the BSC Clearer an amount equal and opposite to the extra-settlement amount paid by or to such Party, plus an amount in lieu of interest. See section 5.5.

6.12 Recovery of Rectification Costs and other Costs which may be incurred

If the TDC determines that a Post-Final Settlement Run or Extra-Settlement Determination should be performed, the TDC may determine that a particular Party or Parties shall bear all or part of the cost incurred.

In addition, Raising Parties should be aware that where rectification of a Trading Dispute requires action by one of its Agents, there may be associated costs involved (dependent on Contractual Agreements in place between the Party and its Agents).

6.13 Trading Dispute Charge

If the TDC resolves that a Trading Dispute raised by a Party is of a vexatious or frivolous nature, it may require the Party raising such a Trading Dispute to pay a standard charge as agreed by the Panel from time to time towards the cost of the administration of the Trading Dispute.

6.14 Materiality Threshold

There is no pre-rectification materiality limit for Trading Disputes. However, if the materiality or estimated materiality of a valid Trading Dispute (i.e. in relation to the affected Settlement Periods) determined by the TDC is less than £3,000, no corrective action will be taken regardless of the determination by the TDC or the Panel (as the case may be) on the validity of such Trading Dispute.

6.15 Multiple Raising Parties

The same Trading Dispute may be raised independently by several Raising Parties. Where the DS recognises that the Trading Disputes arise out of the same circumstances, such Trading Disputes shall, without prejudice to the procedures set out in this BSCP, be consolidated for the purposes of consideration by the BSCCo or the TDC as appropriate.

6.16 References to the Panel and Arbitration

A Party that disagrees with the findings of the TDC may refer the findings to the Panel or to arbitration²⁴ for determination. Any referral to the Panel should be submitted in writing to the Panel Secretary and must be made in accordance with the timescales referred to in section W of the Code.

Any reference to arbitration must be made in accordance with the timescales referred to in section W and section H of the Code.

In the event that the Disputes Secretary is notified that a matter has been remitted to the TDC from the Panel or from an arbitration tribunal in accordance with section W of the Code, the Trading Disputes process shall be followed from 5.3.

1 Section U of the Code sets out the circumstances in which a BSC Agent may correct a Settlement Error without the application of the processes in Section W relating to Trading Disputes.

2 This Dispute Deadline will apply to all Trading Disputes, relating to SVA Half Hourly Data and processes, raised on or after 04 November 2010 (implementation date of P256) regardless of whether such Trading Dispute relates to Settlement Periods which occurred prior to this date.

3 References to the Disputes Secretary shall, where appropriate, include the Disputes Secretary performing duties on behalf of the BSCCo.

4 Where the Trading Dispute relates to Non BM Unit ABSVD, the Party may request assistance from the DS in accordance with paragraph 1.8.

5 If investigations determine that the source of the anomaly is the implementation of MDD, where appropriate confirm that the error exists and agree any required changes with SVAA within 2 WD of the Trading Dispute being raised (the TDC must still agree that the Trading Dispute has been raised in accordance with the necessary time limits and that a Settlement Error exists). MDD should be re-run as agreed in accordance with BSCP509 and all Market Participants should be informed.

6 The Disputes Secretary may issue as many Requests for Assistance as necessary to gather all information required for analysis of the Trading Dispute.

7 Persistent failure to respond to Requests for Assistance will result in the Disputes Secretary reporting the offending Party to the Performance Assurance Board.

8 For Profile Coefficient Trading Disputes, the Trading Dispute must be presented to the TDC within 6 WD of the affected Settlement Day.

9 Where appropriate, the Finding Form should include instructions for rectification. If it is envisaged that Deferral will result in a need for data to be retained beyond the 40 month cut-off, this should be noted on the Deferral form.

10Where rectification of the Trading Dispute requires corrective action by a Raising Party’s agent(s), it should be specified on the BSCP11/07 Trading Disputes Findings that the Raising Party should instruct its agent(s) to make the amendments required.

11For Profile Coefficient Trading Disputes, if the TDC determines that the Profile Coefficient should be recalculated, this instruction must be given by 10:00 on Settlement Day plus 7 WD. All other instructions must be issued at least 15 WD before the next scheduled Settlement Run, unless a shorter period is agreed with the relevant BSC Agent.

12Each BSCCo Agent and each Party shall take or procure its agent to take such steps as are necessary to give effect to a determination of the TDC.

13 A Post Final Settlement Run must be performed within 28 months of the relevant Settlement Day(s) in accordance with Section U of the Code.

14CDCA, SAA, SVAA, FAA and where applicable the CRA, ECVAA, TLFA, NETSO and/or and Interconnector Administrators.

15 BSCP11/07 form will confirm to each BSC Party what action it is required to take.

16 Each BSC Party shall take or procure its agents including but not limited to Data Collectors and Data Aggregators to take such steps as are necessary to give effect to a determination of the TDC.

17 A BSC Party may decide to provide its agent(s) with the BSCP11/07 form as provided by the DS in 5.4.2.

18 Parties should be given sufficient notification prior to the 40 month deadline to allow suitable arrangements to be put in place for data retention beyond the minimum requirements.

19As defined in section W of the Code.

20 Where an ESD is performed prior to the next Timetabled Reconciliation Settlement Run, all payments must be reversed (i.e. the ESD unwound) on or as near as practicable to the Payment Date in respect of the Timetabled Reconciliation Settlement Run, in which the Settlement Error is corrected. This will be achieved by performing a second ESD, with a second set of payments processed by the FAA. See Appendix 6.11.

21 See section 2.2 for further details on exceptional circumstances.

22 Where no end-date is provided at the time this form is submitted, it will be assumed that the alleged Settlement Error is ongoing. However, where possible, Parties will be required to provide an end-date upon request by the BSCCo. Where no end-date is provided, the TDC may impose an end-date for the purposes of its determination. If an end-date is provided but the error extends beyond that date the TDC will amend the end-date to cover all affected Settlement Days.

23 Should you wish to appeal against the decision of the TDC and in doing so refer the matter to the Panel for determination, you will need to submit a referral notification to the Panel Secretary no later than 30 days following the receipt of this notification.

24 With the exception of Post RF rectification decisions.
