This BSC Procedure (BSCP) provides for the Registration and De-registration of Metering Systems. This ensures that no Metering Systems are unaccounted for in the Settlement process. This BSCP also provides for the Registration of Metering Systems under BSCP68 ‘Transfer of Registration of Metering Systems between CMRS and SMRS’.

The Metering Systems involved are all those from which the Central Data Collection Agent (CDCA) collects data. This covers Generator Metering Systems, Interconnector Metering Systems, Metering Systems recording the demand from customers directly connected to the Transmission System, Metering Systems associated with Grid Supply Point (GSP) Group circuits and Metering Systems associated with Systems Connection Point and Exemptable Generating Plants.

Any references to Commissioning Tests are covered in Code of Practice Four (Code of Practice for the Calibration, Testing and Commissioning Requirements of Metering Equipment for Settlement Purposes),and any references to Proving Tests and Commissioning End to End Checks (CEEC) in this BSCP are covered in BSCP02 (Proving Test Requirements for Central Volume Allocation Metering Systems).

All Metering Systems must be uniquely identified to ensure that the data collected from each Metering System is correctly allocated within the various processes under the Code.

Excluded from this BSCP are all Metering Systems that are registered in the Supplier Meter Registration Service (SMRS) and are used for Trading.

Any references to the Registration and de-registration of Boundary Points and System Connection Points are covered in BSCP25 ‘Registration of Transmission System Boundary Points, Grid Supply Points, GSP Groups and Distribution Systems Connection Points.

1.6 Compliance with Code of Practice

Where the registration of a Metering System requires a dispensation against the relevant Code of Practice effective at that time, the Registrant shall ensure that the required consents have been obtained in accordance with BSCP32 prior to the commencement of the registration process in this BSCP20. No registrations of non-compliant Metering Systems shall be accepted without a valid dispensation.

1.7 Other

Any backdating of appointments or registrations must be by bilateral agreement between parties concerned and may not be included in the Registration System retrospectively.

Registrants must take into account any preliminary agreements (e.g. Use of System Agreements or Connection Agreements) that may be required before attempting to register a Metering System in accordance with this BSCP. Similarly, Registrants and MOAs shall take into account, in accordance with BSCP02, the requirements for Proving Tests prior to the REFD in the registration.

A Registrant registering a MOA as part of their registration process may only register a Qualified MOA. MOAs are Qualified under BSCP537 – Qualification Process for SVA Parties, SVA Party Agents and CVA MOAs.

Where the Export Metering System at an Exemptable Generating Plant is Registered in CMRS and the associated Import Metering System is registered in SMRS, the Registrant of the Export Metering System shall ensure that the same MOA is appointed for both the Export and Import Metering Equipment and that the nominated MOA is appropriately Qualified. The Registration of the Import Metering System in SMRS is outside the scope of this BSCP and is covered in BSCP501.

1 Where the New Metering System is associated with an Exemptable Generating Plant and the Import Meter(s) is Registered in SMRS, refer to process 3.8 ‘Registration of a New Metering System which is associated with Exemptable Generating Plant and where the Import Meter(s) is Registered in SMRS’

2 The timescales in this process may vary when there is a transfer of registration as outlined in BSCP68. In this instance, the timescales in BSCP68 should be followed.

3 Suppliers that have Customers directly connected to the Transmission System can register and de-register the Primary BM Unit associated with that Customer premises within 5WD in limited circumstances in accordance with BSCP15

4 In the event that the Metering System is at a Systems Connection Point between two Distribution Systems, the owners of each Distribution System must agree on the identity of the Registrant using Form BSCP20/4.1

5 Where the Electronic flow CRA-I031 is used to register a Metering System the Registrant will need to confirm manually (email/Fax/Post) whether it is the Metering System owner or that it has obtained the Metering System owners consent

6 Where the Meter Technical Details are not valid the registration will be rejected, and the MOAs or Registrant will be required to resubmit the Meter Technical Details under step 3.1.9.

7 The MOA shall seal the new Metering System in accordance with BSCP06

8 Certificate of disconnection is only required where the circuit being de-registered has been disconnected and there is no potential for electricity transfer. Where the circuit is to be registered in Supplier Metering Registration System (SMRS) for trade purposes the certificate of disconnection is not required but the effective date in SMRS shall be required from Supplier Metering Registration Agent. The Certificate of Disconnection is only required prior to the Effective To date.

9This process shall not apply where a Metering System is being transferred from one Party to another as part of the CVA Primary BM Unit CoPBLP in BSCP15 which defines the process for transferring the ownership of Metering Systems in such circumstances.

10 If the registration is objected to, the new registration will not be accepted and the current Registrant shall remain until the objection is resolved

11 Where the Metering Equipment needs to be changed due to a fault or an emergency replacement is required a shorter notice period shall be acceptable in accordance with BSCP06. The notice period may also be decreased if agreed upon by all parties concerned.

12 BSCP20/4.3 shall only be submitted as appropriate where there has been a change to the Meter Technical Details

13 For Distribution Systems connected at Distribution System Connection Points the LDSO registering the metering system should enter the LDSO Id of the other Distribution System to which the relevant DSCP connects. This will enable both LDSOs to receive the CDCA-I012. If there are more than two LDSOs then the CDCA-I012 can be requested through flexible reporting, please refer to BSCP41.

14 In the description of Meter Technical Details to be amended, specify which Metering Sub-system IDs (or all) require a CEEC

15 Relevant fields in sections below should also be completed.

16 In the case of an embedded Primary BM Unit this is the Contracted LDSO.

17 Maximum 10 characters. N.B. If the MSN has to be adjusted by agreement between the MOA and CDCA, then both the old and new values must be recorded on this form, which will constitute the only record of the adjustment.
