BSC Procedure 68

relating to

Transfer of Registration of Metering Systems Between CMRS and SMRS

1. 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.

2. This is BSC Procedure 68, Version 20.0 relating to Transfers of Registration of Metering Systems between CMRS and SMRS.

3. This BSC Procedure is effective from 22 September 2025.

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

1 INTRODUCTION

1.1 Purpose and Scope of the Procedure

The purpose and scope of this BSC Procedure (BSCP) is to enable Third Party Generators to centrally register Third Party Generating Plant (typically embedded generators) such that the Exports of such Third Party Generating Plant can be traded in the Balancing Mechanism without having to go through a Licensed Supplier.

This requires the registration of Metering Systems to be transferred between:

Supplier Volume Allocation (SVA), utilising the Central Switching Service (CSS) and the Supplier Meter Registration Service (SMRS); and
Central Volume Allocation (CVA), utilising the Central Meter Registration Service (CMRS).

It also requires checks to be made to ensure that energy is accounted for in one system but not in both Registration systems. This process is known as “Registration Transfers”. For Settlement purposes, this means that each part (i.e. the Import or the Export) of the Third Party Generating Plant is accounted for in CVA or SVA but not both for any particular Settlement Day.

The Import of a Metering System cannot be registered in CMRS without the corresponding Export. Therefore, a registration transfer from SMRS to CMRS must either include both the Import and Export of the Metering System or consist of the Export only of that Metering System. A registration transfer from CMRS to SMRS can include the Import only or both the Import and Export of a Metering System. This allows consolidators to trade Export Active Energy from an Exemtable Generating Plant in CVA whilst allowing the Import Active Energy to remain in SVA, thus removing the need for a consolidator to have a Supply Licence.

Samples of the forms to be used for Registration Transfers are included in Appendices 4.1, 4.2, 4.5 and 4.6.

The Transfer Co-ordinator will approve (and CRA shall record for audit purposes) the transfer of Metering System Registration from SMRS to CMRS and vice versa. The Transfer Co-ordinator may limit the number of Registration Transfers in progress. Details of the limits are contained in Appendix 4.7. Where a Registrant has had a limitation applied to the number of Registration Transfers in progress, the Registrant may apply to the Transfer Co-ordinator for an increase to the limit of Registration Transfers in progress. The Transfer Co-ordinator may, following consultation with the relevant Parties and Party Agents, permit a temporary increase in the number of Registration Transfers in progress.

Where discrepancies (between the data registered in CMRS and SMRS) arise, the Transfer Co-ordinator shall advise as to which system should be amended to resolve the issue.

Where more than one Registration Transfer is to take place within the Distribution System(s) of a GSP Group within the 30 WD timescale required to complete a Registration transfer, all relevant LDSOs shall be involved in the Registration transfer process. Additional care should be taken when preparing and checking the Aggregation Rules. It may also be appropriate for all the Registration Transfers to have the same Registration Effective From Date or Effective From Date {Regi}.

Any flows referenced in this BSCP can be provided via the Data Transfer Network (DTN) or by any other method agreed by those parties involved. Flows provided via the DTN can be confirmed by email if required. Where a Data Integration Platform interface is referenced for MHHS MSIDs, then the use of that interface shall be mandatory,

The registration of Metering Systems for new connections and disconnections is outside the scope of this BSCP and is covered in BSCP20 for CVA related registrations and BSCP501 for non-MHHS MSIDs and BSCP706 for MHHS MSIDs for SVA related registrations.

3 INTERFACE AND TIMETABLE INFORMATION

3.1 Transfers from SMRS to CMRS

3.1.1 Transfer of both Import and Export Metering Systems^³

1) If the CVA Registrant of Import and the CVA Registrant of Export are the same Party, then that Party may choose to register a single Primary BM Unit comprising Imports and Exports. If the CVA Registrants of Import and Export are different Parties, the Registrants should complete the process individually but with the same proposed and then confirmed REFD and highlight that it is a joint application.

2) If a Metering System is subject to a Shared SVA Meter Arrangement (BSCP550), then there will be a minimum of two SVA Registrants (i.e. a Primary Supplier and Secondary Supplier). The Primary Supplier will take responsibility for resolving any issues that may arise where there are multiple Suppliers involved in the Shared SVA Meter Arrangement. In addition the Primary Supplier will be responsible for initiating the logical disconnection of the actual SVA MSID.

3) Note that the BSCP68 timescales are the default timescales for all related BSCPs.

4) For Registration Transfers from SMRS to CMRS, the REFD (Registration Effective From Date) in CMRS must always equal the ETSD {Regi} (Effective To Settlement Date {Regi}) in SMRS +1 calendar day.

4.3 Transfer Guidelines for Registrants

The Imports of a Metering System cannot be registered in CVA without the corresponding Exports. This means that the Imports of a Metering System cannot be transferred from SVA to CVA without the corresponding Exports and similarly, the Exports of the Metering System cannot be transferred from CVA to SVA without the corresponding Imports.

Any Metering Systems Registered in CVA must be Half-Hourly metered.

While care is taken in the collection and provision of this information, Elexon Limited shall not be liable for any errors, omissions, misstatements or mistakes in any information or damages resulting from the use of this information or action taken in reliance on it.

1 Appointment and de-appointment of SVA MOAs will take place in accordance with the REC Metering Operations Schedule.

2 For Registration Transfers from SMRS to CMRS, the REFD in CMRS must always equal the ETSD {Regi} in SMRS +1 calendar day. Similarly for Registration Transfers from CMRS to SMRS, the RETD in CMRS must always equal the EFSD {Regi} in CSS/SMRS –1 calendar day. All timings are measured in Co-ordinated Universal Time (UTC).

3 The Transfer Co-ordinator shall advise the Registrant if it becomes necessary to invoke the limits of Registration Transfers in Progress (see Appendix 4.7). This may occur at any stage between Ref: 3.1.1.1 and 3.1.1.8. The Transfer Co-ordinator shall advise the Registrant of the next available date for the Registration Transfer to proceed.

4 i.e. Supplier(s).

5 Transfer Co-ordinator will liaise with relevant contacts within each organisation.

6 The CVA MOA may be the same person as the SVA MOA.

7 Provisional Registration: For Registration Transfers from SMRS to CMRS, the CMRS (i.e. the CRA and CDCA), will ensure that the Registration Transfer does not become active in Settlement until it is approved by the Transfer Co-ordinator. The Transfer Co-ordinator will receive regular reports from the CRA on the status of such Primary BM Units in order to monitor their ‘provisional’ status.

8 Primary BM Unit Registration: The timing of Primary BM Unit Registrations may be earlier than 30 WD if the Party has previously met the National Electricity System Operator (NETSO) Registration Requirements of Section 1 of BSCP15.

9 BSCP68 timescales are default for BSCP20.

10 Note that this is a new CVA MSID, even if a site is transferring back to CMRS as following a previous disconnection in CMRS, the Meter would have been logically disconnected.

11 BSCP68 timescales are default for BSCP128.

12 Where the current MOA has sent Meter Technical Details (MTD) to a new MOA, and there is a change to MTD, the current MOA should send the revised MTD to the new MOA until such a time as the current MOA is no longer responsible for the MTD.

13 This step replaces the need for the Supplier to send the Contracted LDSO a D0132 data flow as outlined in BSCP515 Section 3.7.

14 The Proving Test may be performed i) earlier if (a) new Metering Equipment is being installed or (b) appropriate agreement is made with existing interested parties i.e. Registrant(s) (SVA), SVA HHDC for non MHHS MSIDs, or,ADS for MHHS MSIDs, SVA MOA or ii) later at the discretion of the Transfer Co-ordinator dependant on volume of Metering Systems being transferred but by at least 10 WD after REFD.

15 The Transfer Co-ordinator shall advise the Registrant if it becomes necessary to invoke the limits of Registration Transfers in Progress (see Appendix 4.7). This may occur at any stage between Ref: 3.1.2.1 and 3.1.2.13. The Transfer Co-ordinator shall advise the Registrant of the next available date for the Registration Transfer to proceed.

16 SVA MOAs shall qualify in accordance with the REC Qualification and Maintenance Schedule.

17 The Transfer Co-ordinator shall advise the Registrant if it becomes necessary to invoke the limits of Registration Transfers in Progress (see Appendix 4.7). This may occur at any stage between Ref: 3.2.1.1 and 3.2.1.7. The Transfer Co-ordinator shall advise the Registrant of the next available date for the Registration Transfer to proceed.

18 Transfer Co-ordinator will liaise with all relevant contacts with each organisation.

19 If a new Trading Unit is to be formed, refer to BSCP31.

20 The Default Line Loss Factor Class Id and LLFs should be generic for the measurement quantity and voltage connection for that Contracted LDSO. These LLFs will apply until a revised Line Loss Factor Class Id and LLFs have been established in MDD for non-MHHS MSIDs. For MHHS MSIDs, the Default DUoS Tariff ID and LLFs should be generic for the measurement quantity and voltage connection for that Contracted LDSO. These LLFs will apply until a revised DUoS Tariff ID and LLFs have been established in ISD..

21 CVA Metering System will be logically disconnected and therefore a new SVA MSID will be created in the transfer process to SMRS.

22 New SVA MOA may be the same agent as the existing CVA MOA.

23 The de-registering of Primary BM Units and Metering Systems in CMRS is a logical de-registration rather than physical de-registration. It is assumed that the Third Party Generator would have informed the Registrants (CVA) of its intention prior to initiating the Registration Transfer process.

24 These are the ‘old’ SVA MSID(s) that would have been used if this Metering System had been previously registered in SMRS.

25 LLF Class Id will contain the actual LLF Class Id or where this is not known a default LLF Class Id. LLF Class ID renamed DUOS Tariff ID within Industry Standing Data ( ISD).

26 The Proving Test may be performed earlier if (a) new Metering Equipment is being installed or (b) appropriate agreement is made with existing interested parties i.e. Registrant(s) (CVA), CDCA, MOA.

27 The Transfer Co-ordinator shall advise the Registrant if it becomes necessary to invoke the limits of Registration Transfers in Progress (see Appendix 4.7). This may occur at any stage between Ref: 3.2.2.1 and 3.2.2.7. The Transfer Co-ordinator shall advise the Registrant of the next available date for the Registration Transfer to proceed.

28 SVA MOAs shall qualify in accordance with the REC Qualification and Maintenance Schedule.

29 Refer to Appendix 4.3 for further guidance.

30 Refer to Appendix 4.9 for guidance on completing the table and schematic diagram.
