• The person that Generates electricity at that Generating Plant; or

• Another BSC Party with the agreement of the person who generates the electricity at that Generating Plant.

  • Registering the Primary BM Unit to another BSC Party (e.g. a Supplier with whom a Generator may have a Power Purchasing Agreement (PPA) offtake arrangement) is an option to consider if you have a short timescale before the intended energisation date in which to go through the Market Entry process to qualify as a Generator.

Elexon Primary BM Unit Registration

Overview

Primary BM Unit Registration

• BSCP15/4.1⁷ - By 30 or 60 Working Days (WD)⁸ prior to the Effective From Date (EFD) (intended energisation date of the Generating Plant). Alternatively, this information can be completed via the Self-Service Gateway (Elexon Kinnect Customer Solution). This form details the Primary BM Unit being registered. The 60 WD timescale is required if the Primary BM Unit is not of a standard configuration in which case the BSCP15/4.13 form will also need to be submitted. Further details of standard and non-standard Primary BM Units can be found in the Balancing Mechanism Units Guidance. You will also need to provide site diagram(s) showing the location of the Metering Equipment (in particular the Settlement current and voltage transformers (CTs/VTs)), CT/VT Ratios, any System Connection Points at or near the proposed Boundary Point(s) and any back up SVA connection and interlocking arrangements.

• BSCP75/4.2⁹ - By 20 WD prior to the EFD. This form details the Aggregation Rules for the Primary BM Unit(s). For an embedded (distribution connected) Primary BM Unit, then the rule will also need to include reference to a Line Loss Factor (LLF). Guidance on writing Aggregation Rules can be found in the Aggregation Rules Guidance. Note that the identifiers in the Aggregation Rules need to match those in the Meter Technical Details.

• For an embedded (distribution connected) Primary BM Unit you will also need to contact the relevant Licenced Distribution System Operator (LDSO) to request that they send CVA Line Loss Factors (LLFs) to Elexon.

• For an embedded (distribution connected) Primary BM Unit, the relevant LDSO will need to update the relevant GSP Group Take Aggregation Rules. These are prepared by the Central Data Collection Agent (CDCA) and signed off by the LDSO.

• For a directly connected (Transmission) Primary BM Unit, the NETSO will need to register the Transmission Systems Boundary Point.

Metering Registration

• BSCP20/4.1¹⁰ – By 20 WD prior to the EFD to bm.unit@elexon.co.uk and neta@imserv.com. This form details the CVA Metering System Identifier (MSID) being registered for the Primary BM Unit, and the CVA Meter Operator (CVA MOA) appointed by you¹¹ . You can reserve a CVA MSID for the site in advance by emailing the CRA (neta@imserv.com), stating the Name, whether it is Transmission or Distribution connected, and its location (England and Wales, North of Scotland, or South of Scotland). The CRA will provide details of the CVA MSID. For a Distribution connected Metering System, the LDSO may determine that a separate LLF is required to be applied to the Export and the Import Flows; in this case, two CVA MSIDs would be required.

• For an embedded (distribution connected) Primary BM Unit, you will also need to contact the relevant LDSO to request that they to cancel any SVA MPANs for the Distribution connection that they may have allocated, as the CVA MSID will be used instead.

• BSCP20/4.3 – By 16 WD prior to the EFD to bm.unit@elexon.co.uk and neta@imserv.com.This form details the Meter Technical Details and will need to be submitted by the CVA MOA appointed by you.

• Metering Equipment should be compliant with the relevant Code of Practice at the time of first registration for Settlement purposes, however should any aspect of your Metering System be unavoidably non-compliant, there is a process for making an application for a Metering Dispensation from the relevant Code Of Practice via BSCP32¹² . Elexon can advise prior to submission and we recommend that the signed BSCP32/4.1 Form and any supporting documentation is submitted at least 14 weeks prior to the EFD. Metering Dispensations should be sent to dispensations@elexon.co.uk. Note that Panel Committees may approve, reject or defer a decision on a Metering Dispensation so the ideal situation is for all metering to be compliant with the relevant Code of Practice. Further information on the Metering Dispensation process can be found on the Metering Dispensations page of the BSC Website.

• Your CVA MOA must Commission and Prove the Metering System in accordance with Code of Practice 4¹³ and BSCP02¹⁴ .

Approval to Energise

Other Considerations

Electricity Market Reform (EMR)

Licence Exempt Generating Plant

• BSCP15/4.5a - By 20 WD prior to the EFD to bm.unit@elexon.co.uk. This form details the site, why you believe that it qualifies as Exemptable status and the required Production/Consumption (P/C) Flag for the Primary BM Unit. On the form please clearly explain with reference to Class or specific exemptions why you believe that the site qualifies as Exemptable. Alternatively, you can flag your Primary BM Unit as an Exempt Export Primary BM Unit via the Self-Service Gateway (Elexon Kinnect Customer Solution). Within 20 WD of receipt, Elexon will then send you a BSCP15/4.5b form confirming/rejecting the application for Exempt Export status or confirm this Unit via the Self-Service Gateway (Elexon Kinnect Customer Solution).

  • If the Exempt Export status has been approved, Elexon will confirm Exempt Export status and the P/C Flag to the CRA.

Metered Volume Reallocation Notifications (MVRNs)

• The relevant MVRNA i.e. the person responsible for submitting the MVRNs to central systems

• The Lead Party for the Primary BM Unit i.e. the BSC Party FROM whom the metered volumes will be moved

• The Subsidiary Party for the Primary BM Unit i.e. the BSC Party TO whom the metered volumes will be moved

• The Lead Party Energy Account. This must be either Production or Consumption and must be the same as the Subsidiary Party Energy Account

• The Subsidiary Party Energy Account. This must be either Production or Consumption and must be the same as the Lead Party Energy Account

• The Primary BM Unit Identifier

• The required Effective From Date

1. Primary BM Unit T_ELEX-1 has an EFD of 01/12/16 (a Thursday)

2. Elexon issue Approval to Energise Email before 14:00 29/11/16 (a Tuesday)

3. On 29/11/16, Primary BM Unit T_ELEX-1 entered into the central systems with an EFD of 01/12/16

4. On 29/11/16, Primary BM Unit T_ELEX-1 now entered into the central systems, allowing a MVRNA Authorisation for it to be created with an EFD of the next day, i.e. 30/11/16 (a Wednesday). MVRNA Authorisation Identifier and unique MVRNA Key then issued to MVRNA with an EFD of 30/11/16. (MVRNA Authorisation not valid before 30/11/16 so central System would reject any MVRN submission prior to that date)

5. On 30/11/16, MVRNA can submit MVRNs for Primary BM Unit T_ELEX-1 from at earliest SP1 of the Primary BM Unit EFD i.e. 01/12/16 (Primary BM Unit not valid before 01/12/16 so central System would reject any MVRN submission prior to that date)

1. Primary BM Unit T_ELEX-1 has an EFD of 01/12/16 (a Thursday)

2. Elexon issue Approval to Energise Email before 14:00 30/11/16 (a Wednesday)

4. On 30/11/16, Primary BM Unit T_ELEX-1 now entered into the central systems , allowing a MVRNA Authorisation for it to be created with an EFD of the next day, i.e. 01/12/16 (a Thursday). MVRNA Authorisation Identifier and unique MVRNA Key issued to MVRNA with an EFD of 01/12/16. (MVRNA Authorisation not valid before 01/12/16 so central System would reject any MVRN submission prior to that date)

5. On 01/12/16, MVRNA can, from at earliest midnight, submit MVRNs for Primary BM Unit T_ELEX-1, however the earliest SP will be SP2 on 01/12/16 (Primary BM Unit not valid before 01/12/16, and Gate Closure has passed for SP 1, so central System would reject any MVRN submission prior to that SP)
