BSC Procedure 509 relating to Changes to Market Domain Data

1. Reference is made to the Balancing and Settlement Code for the Electricity Industry in Great Britain and, in particular, to the definition of "BSC Procedure".

2. This is BSC Procedure 509 Version 23.0 relating to Changes to Market Domain Data.

3. This BSC Procedure is effective from 1 September 2021.

4. This BSC Procedure has been approved by the Panel.

1. Introduction

1.1 Purpose and Scope of the Procedure

The purpose of this BSC Procedure (BSCP) is to ensure that all changes to Market Domain Data (MDD) within the Supplier Volume Allocation (SVA) arrangements are made in an auditable and controlled manner and where appropriate with due consultation with the affected parties. MDD refers to those items of data that are required to be passed from one party to another by the Supplier Volume Allocation Agent (SVAA).

This BSCP covers the raising of a change (an MDD Change Request ‘MDD CR’), authorisation and notification of MDD items to all relevant Market Participants (MPs) including the SVAA. The BSCP also covers the raising of a request to change an item of MDD whose values are linked to BSCCo developed software and the subsequent notification of such changes. However, in order to accommodate potential software changes, their authorisation must be carried out in accordance with BSCP40 “Change Management”. In addition, this BSCP outlines the process for effecting emergency changes to MDD.

A complete set of MDD entities together with their authorisation routes is contained in Appendix 4.1.

The BSCP does not cover the distribution and implementation of changes to MDD, or changes to SVA system standing data, which are covered by BSCPs 508, 'Supplier Volume Allocation Agent' and 507, 'Supplier Volume Allocation Standing Data Changes' respectively. Neither should it be used to implement changes to the structure of the MDD file. This file is included in the Baseline Management System (BMS), and is changed in accordance with BSCP40.

1.2 Main Users of the Procedure and their Responsibilities

The main users of this BSCP are:

    • Panel - approves changes to MDD

    • MPs – registered in accordance with BSCP38 for the purpose of interfacing with the BSCCo when managing changes to MDD1.

    • SVAA - receives notification of authorised changes to MDD from BSCCo and is involved in progressing changes to the SVAA calendar, preparing Impact Assessments (IAs), and agreeing release schedules.

1.3 Use of the Procedure

This BSCP must be used to progress all changes to those data items designated as MDD. The need to make changes to MDD may be identified by the Panel, one of its Panel Committees, relevant BSC Agents, or Parties, depending upon the nature of the change. Appendix 4.1 outlines who can raise an MDD CR and provides a list of MDD Entities. In order to progress an MDD CR, the originator is required to complete the MDD CR (using F509/01) with the aid of the scenarios set out in BSCP509 Appendix 2: MDD Change Request Entity Validation2 together with the valid section from the MDD Entity Form. Appendix 4.4 outlines the MDD Entity forms used by this BSCP.

There are two key milestones in this BSCP:

    • The SVAA is to be notified by BSCCo of a change to MDD no later than 7 Working Days (or as otherwise agreed between BSCCo and the SVAA) before the Go Live Date.

    • MPs have 2 Working Days from the receipt of the MDD to contact BSCCo if they believe that the change to MDD as notified is not as agreed or invalid. If BSCCo determines that the MDD publish is not as agreed it will assess the severity of the impact of any error. BSCCo will then determine whether any relevant error should be removed in the next publish of MDD or whether the emergency fix process should be used (see Section 3.5).

1.4 Balancing and Settlement Code Provision

This BSCP has been produced in accordance with the provisions of the Balancing and Settlement Code (the Code). In the event of an inconsistency between this BSCP and the Code, the Code shall prevail.

1 The previous version of BSCP509 required MPs to register in accordance with form F509/02 which was contained within this BSCP.

2 BSCP509 Appendix 2: MDD Change Request Entity Validation, details an array of scenarios in which an MDD CR may be required along with the information that should be included with such MDD CRs.

3 LDSOs will include Independent LDSOs.

4 The PEG consists of volunteer industry experts requested by Elexon and appointed on an ad-hoc basis.

5 Steps 3.1.7- 3.1.10 may be repeated on request of the PrA as long as this does not prejudice the timescale in 3.1.11.

6 F509/01 form must be completed with the aid of the scenarios set out in BSCP509 Appendix 2: MDD Change Request Entity Validation

7 Approved MDD changes for new Suppliers, new LDSOs, existing LDSOs and new Party Agents should be made in accordance with the criteria in Appendix 4.3. MDD changes related to MDD Housekeeping, Registration of New Market Participants or registration of Additional BM Units should follow 3.6.

8 Participants raising CRs relating to Additional BM Unit registration, BM Unit deregistration or Cessation of Supplier should ensure the procedures within BSCP15 are followed. Participants raising CRs in relation to the registration or deregistration of a Supplier ID should ensure the procedures within BSCP65 are followed. BSCCo will raise CRs relating to Unmetered Supplies Operational Information in accordance with BSCP520. GPS Group Registration is progressed through BSCP25.

9 Refer to the MDD release schedule published on the BSC Website for general changes.

10 If any proposed change(s) will result in a change to the MDD software, proceed in accordance with BSCP40.

11 BSCCo will issue a release schedule for general changes to MDD and for new Market Participants,Party Agents and Additional BM Units. The Change Request submission dates will differ for each type of change, however they will both be included in the same MDD Publish.

12 An emergency fix will only be required if, following an MDD publish and subsequent go-live, an error in the MDD data is reported, either by BSCCo, the SVAA or a Market Participant. An emergency fix can be defined as an additional publish of MDD which would include an incremented version number.

13 Authorisation to be sought from Panel.

14 A Housekeeping CR is one which is of a minor nature and it is self-evident that the change would improve the data within MDD.

15 This may include Market Participant, Market Participant Role, SMRA Appointment and / or BM Unit for Supplier in GSP Group data.

16 Refer to the MDD release schedule published on the BSC Website for new Market Participants and Party Agents.

17 A change to end the use of an AFYC Set will not be permitted if it results in SVA Metering Systems having invalid combinations of Profile Class, SSC and GSP Group.

18 The annual updates of these entities will be progressed simultaneously.

19 Changes relating to this entity shall be agreed with the relevant LDSO prior to making a formal submission.

20 This information is not included in the MDD database, but can be found on the BSC Website.

21 Excluding SVA MOAs who will be qualified in accordance with the Retail Energy Code Qualification and Maintenance Schedule
