1. Introduction

1.1 Purpose and Scope of the Procedure

This BSCP defines the key interfaces, interdependencies and timetable for the registration and de-registration of Balancing Mechanism (BM) Units by the Party, which, for the avoidance of doubt, includes:

    • New registration of Primary BM Units;

    • De-registration of Primary BM Units;

    • Changes in the Final Physical Notification (FPN) flag status;

    • Registration of Seasonal Estimates of the Maximum Positive Magnitude and Maximum Negative Magnitude Primary BM Unit Metered Volume;

    • Application for Exemptable status for a Generating Plant and Exempt Export status for the associated Primary BM Unit(s), including election of the Production / Consumption Status for the Exempt Export Primary BM Unit(s) by the Lead Party;

    • Change of Production / Consumption Status for an Exempt Export Primary BM or Secondary BM Unit by the Lead Party;

    • Termination of Exemptable status for a Generating Plant and the Exempt Export status of the associated Primary BM Unit(s);

    • Mid-Season Changes of the Maximum Positive Magnitude and Maximum Negative Magnitude Primary BM Unit Metered Volume;

    • Monitoring of BM Unit Metered Volumes for breaches of Generation Capacity and Demand Capacity;

    • Change of Central Volume Allocation (CVA) Primary BM Unit Lead Party;

    • Transfer of Supplier Identifier (ID); and

    • Notification of Switching Group1.

    • New registration of Secondary BM Units;

    • De-registration of Secondary BM Units

1.1.1 Use of the Self-Service Gateway

Where a Party has access to the Self-Service Gateway and an equivalent online form is provided, the Party may use the online form as an alternative to the paper forms defined in this BSCP.

Where a Party has provided data using the Self-Service Gateway, BSCCo may use the service to validate and confirm the input data or to request additional data. Where this is the case, these online transactions will represent a valid equivalent to the transactions defined in this BSCP.

Please note that there will not always be a one-to-one equivalence between the data collected via the Self-Service Gateway and the paper forms defined in this BSCP. For example, data collected in one paper form, may be collected by more than one online form. Conversely, a single online form may collect data from more than one paper form.

All references to the provision of information using BSCP forms in this Procedure, should be construed as provision either by a paper form or via the Self-Service Gateway. References to the CRA, including checks performed by the CRA, may include the Self-Service Gateway as applicable.

1.1.2 Baselined Additional or Secondary BM Units

Suppliers and VLPs can opt for their Additional and Secondary BM Units to be a “Baselined BM Unit”. A Baselined BM Unit consists of at least one MSID Pair or AMSID Pair that will have a baseline settlement volume calculated, which will also be used to calculate Delivered Volumes. Registration of a Baselined BM Unit is incorporated into sections 3.4 and 3.21.

Note that the Lead Party for a Baselined BM Unit must still submit an FPN to the NETSO, but the FPN is not used to calculate Non-Delivery Charges. Instead Settlement systems calculate their own FPN equivalent known as the “Settlement Expected Volume” (detailed in BSCP602). The Lead Party specifies (when they allocate each MSID Pair or AMSID Pair to the Baselined BM Unit) how this will work:

1. Baselined MSID Pairs or AMSID Pairs: The SVAA will use historic metered data to calculate the baseline consumption for the MSID Pair or AMSID Pair (in accordance with the Baselining Methodology Document agreed by the BSC Panel);

2. Non-Baselined MSID or AMSID Pairs: The Lead Party calculates the FPN-equivalent, and submits a total figure (per BM Unit and Settlement Period) for all the non-Baselined MSID Pairs and AMSID Pairs; or

3. Inactive MSID Pairs or AMSID Pairs: Temporarily excluded from the BM Unit (for Settlement purposes). Secondary BM Units only.

1.2 Main Users of the Procedure and their Responsibilities

The main users of this procedure are:

(a) The Party that is de-registering the relevant Primary BM Unit;

(b) The Party that is registering the relevant Primary BM Unit;

(c) The Virtual Lead Party or Asset Metering Virtual Lead Party that is de-registering the relevant Secondary BM Unit;

(d) The Virtual Lead Party or Asset Metering Virtual Lead Party that is registering the relevant Secondary BM Unit;

(e) The Lead Party for an Exempt Export Primary BM Unit (or a Primary BM Unit which is the subject of an Exempt Export status application);

(f) The Central Data Collection Agent (CDCA);

(g) The Central Registration Agent (CRA);

(h) The National Electricity Transmission System Operator (NETSO);

(i) Supplier Volume Allocation Agent (SVAA);

(j) Licensed Distribution System Operators (LDSOs);

(k) BSCCo; and

(l) The Panel.

1.3 Key Milestones

The key milestones in this procedure are:

    • Detailed notification of ‘registration’ or reconfiguration of a Primary BM Unit (except a Non-Standard Primary BM Unit or Additional Primary BM Unit) at least 30 Working Days (WD) prior to the Effective From Date;

    • 60 WD notification of registration or reconfiguration of a Non-Standard Primary BM Unit. A longer timescale is required in order that the application may be properly considered by BSCCo, the NETSO and the Panel. The Party should advise BSCCo of any such applications at the earliest opportunity such that indicative registration timescales and Effective From Dates may be discussed.

    • 15,18 WD notification of registration of Additional Primary BM Unit, unless FPN flag is set to ‘yes’ where 30 WD notification may be needed (see section 1.6).

    • 15 WD notification of registration of Secondary BM Unit;

    • 20 WD notification of de-registering Primary BM Unit (30 WD for a Base Primary BM Unit) prior to proposed Effective To Date;

    • 20 WD notification of de-registering Secondary BM Unit prior to proposed Effective To Date;

    • New Suppliers notified to Supplier Volume Allocation (SVA) at least 30 WD prior to the Effective From Date;

    • 5 WD notification of transfer of Directly Connected Demand Primary BM Units, if the criteria set out in section 3.13 are satisfied;

    • 5 WD notification of Change of CVA Primary BM Unit Lead Party , if the criteria set out in section 3.13 are satisfied; and

    • 1 WD notification of transfer of Supplier ID process (Change of SVA Primary BM Unit Ownership).

The notice period required to register and de-register a BM Unit, excluding Base Primary BM Units, may be reduced if there is an agreement between the CRA/BSCCo/Party/NETSO.

1.4 Balancing and Settlement Code Provision

This BSCP should be read in conjunction with the Code and in particular Section K. 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 NETSO Registration Requirements

FPN flag set to Yes

Where the Party is registering a BM Unit which has the FPN flag set to Yes, the Party should consult with the NETSO to ensure compliance with the Grid Code and the Connection and Use of System Code regarding timescales. Failure to comply with the Grid Code and the Connection and Use of System Code may delay the registration of the BM Unit and hence the Party would not be able to trade using that BM Unit. The delay may be as a result of procurement, installation and testing of operational metering and Electronic Data Transfer (EDT) and Electronic Despatch Logging (EDL) facilities, as appropriate. This BSCP refers to the last stage of the registration process of the BM Unit.

Offshore Power Park Modules

Where the Party has 2 or more Offshore Power Park Modules for whose Exports the Metering System(s) is or are registered in CMRS, the Party may either:

    • Apply to register each Power Park Module as a separate Primary BM Unit; or

    • Apply to register a single Primary BM Unit for some or all of the Offshore Power Park Modules (a ‘Combined Offshore BM Unit’).

A Party may only register a Combined Offshore BM Unit if the NETSO determines that the requested configuration of Offshore Power Park Modules is suitable to constitute a single Primary BM Unit. Where the Party requests a Combined Offshore BM Unit in its Registration of Primary BM Unit form BSCP15/4.1, BSCCo will confirm with the NETSO whether it approves the configuration. BSCCo recommends that the Party consults with the NETSO before submitting this form, to avoid any delay in the registration process.

1.7 BSC Website list of Suppliers which have satisfied the criteria to complete a change of Primary BM Unit Lead Party within 5WDs for a Primary BM Unit with CVA metering and associated with a Customer premises

BSCCo will publish and maintain a list on the BSC Website of the Party Name and ID of those Suppliers who satisfy the criteria referred to in section 3.14 of this procedure, and who have submitted a completed form BSCP15/4.10 Part A2 to BSCCo in accordance with 3.15.1.

Note that BSCP15/4.11 Parts A and B must be received by BSCCo prior to a Change of Primary BM Unit Lead Party becoming Effective. The Primary BM Unit Effective From Date requested on the (re) registration form must be the calendar date after the Effective To Date requested on the de-registration form.

Where a BM Unit has the FPN flag set to “Yes” Parties must comply with the NETSO Registration Requirements, especially paragraph 1.6 above, and the BM Unit’s Effective From Date will be the same as the NETSO Commission Date.

Any change of Primary BM Unit Lead Party must be approved by BSCCo before the requirements of this and any related procedure are initiated.

1.8 Obligations

Parties must have successfully completed Qualification under Section O of the BSC before the Effective From Date of a BM Unit registration in order for that BM Unit registration to become effective. However, Parties may begin the process of registering BM Units in accordance with this BSCP before they have completed Qualification under Section O of the BSC (relating to communications requirements), provided that they have begun the process of obtaining such Qualification.

1.9 Primary BM Units for CFD or CM Assets

The BSC requires that any Primary BM Units with Contract For Difference (CFD) Assets shall comprise only those Assets allowed by the CFD.

Primary BM Units for CFD Assets Registered in Central Meter Registration Service (CMRS)

Lead Parties will be able to register Primary BM Units for Metering Systems registered in CMRS under the existing processes and approach. This is because in CMRS the Primary BM Unit is specific to the Generating Unit and it is therefore possible to change Primary BM Unit ownership (retaining the same identifier). The Primary BM Unit can therefore exist for the lifetime of the Generating Unit, and consequently the lifetime of the CFD. This means that new registration arrangements or processes are not necessary.

Primary BM Units for CFD or CM Assets Registered in SMRS

Additional Primary BM Units are not a permitted CM metering option. Metered volumes associated with CM Assets registered in SMRS cannot be provided to a CM Settlement Services Provider using Additional Primary BM Units. CM Assets may still be allocated to Additional Primary BM Units, registered under process 3.4.

Additional Primary BM Units for CFD Assets registered in SMRS may be provided to a CFD Settlement Services Provider (CFDSSP) to be used for CFD settlement purposes. The registration of Additional Primary BM Units for CFD Assets shall follow process 3.18. Additional Primary BM Units for non-CFD Assets registered in SMRS should follow 3.4.

Additional Primary BM Units for CFD Assets Registered in SMRS

Both Lead Parties and BSCCo may initiate the registration process for Additional Primary BM Units for CFD Assets registered in SMRS using process 3.18. Additional Primary BM Units for CFD Assets are not liable for the Section D charge for Additional Primary BM Units. Consequently all Additional BM Unit registrations for CFD Assets must be confirmed with or instructed by the CFDSSP, and shall follow a naming convention.

The CFDSSP instructs Additional Primary BM Unit registration details to BSCCo based on information that generators with a CFD are obliged to notify to the CFDSSP, such as when the Additional Primary BM Units are needed. This reduces the need for Lead Parties to manage the Additional Primary BM Unit registration process. Lead Parties should find Additional Primary BM Units are registered and available for use when needed.

Where it is not known which Supplier will take responsibility for Metering Systems associated with a generator with a CFD, BSCCo will register Additional Primary BM Units for a set of Suppliers. The set will be based on a list maintained by BSCCo. The list is maintained in accordance with section 3.20. Each set of Additional Primary BM Units will be associated with the relevant CFD for the lifetime of the CFD. Only one of the Additional Primary BM Units in the set shall be ‘active’ on any particular Settlement Day.

In SMRS the Primary BM Unit represents the Supplier’s Metering System(s), so the Generating Unit(s) must be assigned to an Additional Primary BM Unit so that the Primary BM Unit Metered Data relates to the relevant CFD and can therefore be used by the CFDSSP for CFD Settlement purposes.

CFD Generating Unit(s) must move between Additional Primary BM Units as responsibility under the BSC for the Metering System(s) changes i.e. as a CFD generator changes Suppliers/Offtakers its Metering Systems must move from its old Supplier’s Additional Primary BM Unit to its new Supplier Additional Primary BM Unit. Supplier Primary BM Unit ownership can only take place when a Supplier transfers its Supplier ID i.e. ownership of the Supplier ID (and license) is transferred. Additional Primary BM Units registered for CFD Assets will therefore only last for the lifetime of the CFD. When the CFD expires the CFDSSP will instruct BSCCo to deregister the relevant Additional Primary BM Units to coincide with the expiry of the CFD. The CFDSSP will know when a CFD expires.

3.8 Mid-Season Changes of Generation Capacity and Demand Capacities by the Lead Party

This process supports the Code obligation on Parties to revise GC/DC capacity of a Primary BM Unit by an amount specified in Section K3.4.

Parties have the right to downwardly revise the magnitude of DC twice during a BSC Season when the magnitude of the capacity of a Supplier Primary BM Unit has decreased. Parties are not permitted to downwardly revise the magnitude of GC.

Parties should note that where a revised GC/DC submission causes a Trading Unit to change its P/C Status in accordance with Section K3.5, any MVRNA Authorisation will be terminated in accordance with Section P3. Parties may therefore need to re-establish such MVRNA Authorisations in accordance with BSCP71.

Where a change in a Primary BM Unit’s Generation Capacity or Demand Capacity results in the FPN Flag being changed to “Yes” the Party is required to complete BSCP15/4.1, or the relevant section of the Self-Service Gateway.

For BM Units associated with Metering Systems registered with the CRA, if the change in Generation Capacity or Demand Capacity is required due to a change to the configuration of the BM Unit, please refer to the BSCP section [new] and form BSCP15/4.1 to re-register the reconfigured BM Unit.

3.10 Application for Exemptable Generating Plant Status and Exempt Export Status for the Associated Primary BM Unit(s)

This process supports a Lead Party’s ability under Section K1.5 to apply for Exemptable status for its Generating Plant. If the Party’s application is successful, the Primary BM Unit(s) comprising the Exemptable Generating Plant will be granted Exempt Export status.

In accordance with Sections K1.5 and K3.5, the Lead Party must elect whether the P/C Status of each of its Exempt Export Primary BM Units is to be Production or Consumption. To do this, the Lead Party must elect a P/C Flag setting of either Production or Consumption for each Primary BM Unit as part of its application for Exemptable Generating Plant status. The Lead Party’s elected P/C Flag setting will apply from the date that the Primary BM Unit’s Exempt Export status (if granted) becomes effective. It will override the normal determination of P/C Status described in K3.5.2 such that the Exempt Export Primary BM Unit’s P/C Status will be fixed as either Production or Consumption accordingly.

Once a Primary BM Unit has been granted Exempt Export status, its P/C Status as elected by the Lead Party through the Primary BM Unit’s P/C Flag setting does not change unless the Lead Party makes a new election (by following procedure 3.12 or 3.13 as appropriate) or the Primary BM Unit’s Exempt Export status is terminated (by following procedure 3.11).

3.12 Change of Production / Consumption Status for an Exempt Export Primary BM Unit by the Lead Party

This process supports a Lead Party’s ability under K3.5 to change the previously-elected P/C Status for an Exempt Export Primary BM Unit, by enabling the Lead Party to change the Primary BM Unit’s P/C Flag setting from Production to Consumption or vice versa.

Parties needing to elect the P/C Status of a new Exempt Export Primary BM Unit for the first time should refer to procedure 3.10 for details of how to set the Primary BM Unit’s P/C Flag.

Where an existing Exempt Export Primary BM Unit is the subject of a Change of CVA Primary BM Unit Lead Party (CoPBLP), Parties should follow procedure 3.13 to ensure that the Party registering the Primary BM Unit as part of the CoPBLP elects the P/C Status that it wishes to apply from the CoPBLP Effective From Date. In these circumstances, it is not necessary to additionally follow procedure 3.12.

Where an existing Exempt Export Primary BM Unit is the subject of a Transfer of Supplier ID (Change of SVA Primary BM Units Ownership), Parties should refer to procedure 3.14 for details of how the Supplier ID Transferee is notified of the Primary BM Unit’s P/C Status. Any Supplier ID Transferee wishing to change the Exempt Export Primary BM Unit’s P/C Status should follow this procedure 3.12.

3.13 Change of CVA Primary BM Unit Lead Party

NOTE: Suppliers taking part in this process must have satisfied the criteria detailed in 3.14 and registered with the CRA.

Prior to initiating this process the Party registering the Primary BM Unit(s) as part of the Change of Primary BM Unit Lead Party (CoPBLP) is required to have acceded to the BSC and completed Party registration and qualification. If appropriate, the Party should also have completed all the NETSO requirements.

The timescales noted within this process are based on the existing MSID(s), Primary BM Unit(s) and Trading Unit registrations being transferred from one Party to another with the associated Meter Technical Details (MTDs), Metering Dispensation(s) and Aggregation Rules. If Parties wish to change any of these registrations (for example to effect changes to configuration and entity Ids) then additional BSCPs may need to be followed and/or the lead-time for completing the process may be increased. Where this applies, Parties should contact BSCCo for advice on the process to be followed and documentation required.

If there are no changes to the registration data associated with the Primary BM Units and the prerequisites stated have been met then Parties may use this process in order to transfer Primary BM Unit(s) and associated MSID(s), MTDs, Metering Dispensations, Aggregation Rules and an associated Trading Unit through this procedure. Under these circumstances Parties will not be required to carry out additional steps in this BSCP, BSCP20, BSCP31, BSCP32 and BSCP75 in order to complete the transfer.

Where a Primary BM Unit is already an Exempt Export Primary BM Unit, the Party registering the Primary BM Unit as part of a CoPBLP is required to elect the P/C Flag setting (and thereby the P/C Status) which will apply to the Exempt Export Primary BM Unit from the Effective From Date of the CoPBLP. All other registration details (including the Exempt Export Primary BM Unit’s Trading Unit) will be unchanged unless a change is expressly requested. Where this applies, Parties should contact BSCCo for further information.

Parties wishing to apply for Exempt Export Primary BM Unit status should refer to procedure 3.10.

De-Registration Secondary BM Unit Data Requirements

Name:

Secondary BM Unit Id:

NGC BM Unit ID:

Effective To Date:

The NGC BM Unit ID must be provided for all Secondary BM Units with the FPN Flag set to ‘Y’.

1 Per section K3.1.4B, Power Park Modules may belong to a Switching Group on the basis that Plant and Apparatus can be selected to run in any of the BM Units belonging to that Switching Group. A ‘Switching Group’ is described in Section K3.1.4A of BSC.

2 Must be authorised by a Category A authorised signatory

3 Not required for Change of CVA Primary BM Unit Lead Party unless any changes are to be made to existing registration data.

4 If the CT / VT ratios are not known 30WD / 60WD prior to the EFD, this information should be sent separately by 16WD prior to the EFD.

5 If a Primary BM Unit registration is requested using Electronic File Data Transfer, the passwords and signatures are not required as the access control to the participant system is sufficient authentication.

6 Where the Party is applying to register two or more Offshore Power Park Modules as a Combined Offshore BM Unit, BSCCo recommends that the Party consults with the NETSO before submitting this form.

7 This information is required to help ensure the energy flow(s) for the proposed Boundary Point(s) are accounted for, where necessary (e.g. under an existing Metering Dispensation for difference metering), in the Aggregation Rules of any associated Volume Allocation Units (e.g. Interconnectors, other relevant BM Units, Grid Supply Points, GSP Groups or Distribution System Connection Points).

8 Suppliers that have Customers directly connected to the Transmission System can register and de-register the BM Unit associated with that Customer premises within 5WD if the criteria in Section 1.7 have been satisfied.

9 Where the Primary BM Unit has the FPN flag set to Yes the NETSO must be contacted at least 30 WD prior to EFD.

10 Metering Systems are registered in accordance with BSCP20

11 If the CT / VT ratios are not known 30WD / 60WD prior to the EFD, this information should be sent separately by 16WD prior to the EFD.

12 If a BM Unit registration is requested using Electronic File Data Transfer, the passwords and signatures are not required as the access control to the participant system is sufficient authentication.

13 Where the Party is applying to register 2 or more Offshore Power Park Modules as a Combined Offshore BM Unit, BSCCo recommends that the Party consults with the NETSO before submitting this form.

14 This information is required to help ensure the energy flow(s) for the proposed Boundary Point(s) are accounted for, where necessary (e.g. under an existing Metering Dispensation for difference metering), in the Aggregation Rules of any associated Volume Allocation Units (e.g. Interconnectors, other relevant BM Units, Grid Supply Points, GSP Groups or Distribution System Connection Points).

15 The TLM for an Interconnector BM Unit will be set to 1, irrespective of the value of the TLF

16 If the Primary Base BM Unit is an Exempt Export Primary BM Unit, the Lead Party can change the Primary BM Unit’s allocated Trading Unit by providing notification in accordance with BSCP31.

17 Note that, with the exception of any Exempt Export Primary BM Units in Base Trading Units which have explicitly elected to have a P/C Status of Production, all Primary BM Units in Base Trading Units will always have a P/C Status of Consumption in accordance with Section K3.5.

18 The EFD must align with MDD Release Schedule and be agreed between the NETSO, CRA, Party and BSCCo as applicable

19 If an Additional Primary BM Unit is requested using Electronic File Data Transfer, the passwords and signatures are not required as the access control to the participant system is sufficient authentication. Where faxes are used, participants are required to submit hard copies of the forms by post in case the faxed signatures are illegible.

20 If the Additional Primary BM Unit is an Exempt Export Primary BM Unit, the Lead Party can change the Primary BM Unit’s allocated Trading Unit by providing notification in accordance with BSCP31. If no notification is provided by the Lead Party, the Primary BM Unit will be allocated to the Base Trading Unit for its GSP Group.

21 Note that, with the exception of any Exempt Export BM Units in Base Trading Units which have explicitly elected to have a P/C Status of Production, all BM Units in Base Trading Units will always have a P/C Status of Consumption in accordance with Section K3.5.

22 Primary BM Unit registration timescales may be reduced in certain circumstances if the registering Party agrees that the registration will not be withdrawn or amended after the ‘point of no return’.

23 If the Primary BM Unit is an Embedded BM Unit, Party requests from LDSO. If the Primary BM Unit is a Directly Connected Primary BM Unit, Party requests from NETSO.

24 Any relevant Metering Systems should be de-registered in accordance with BSCP20

25 If a Primary BM Unit De-registration is requested using Electronic File Data Transfer, the passwords and signatures are not required as the access control to the participant system is sufficient authentication. Where faxes are used, participants are required to submit hard copies of the forms by post in case the faxed signatures are illegible.

26 Party to initiate BSCP509 before the de-registration form is submitted to the CRA

27 Where the Primary BM Unit has a FPN set to No, the NETSO does not need to be informed of the De-Registration

28 The Supplier needs to ensure all Metering Systems associated with the additional Supplier Primary BM Unit are re-allocated to either the Base Primary BM Unit or another Supplier BM Unit associated with the same GSP Group (BSCP503 & 507) unless circuits are being disconnected.

29 Notification of such Primary BM Units shall be sent to the SVAA in its capacity as the Market Domain Data manager

30 Please refer to the ‘Generation Capacity (GC) and Demand Capacity (DC) Estimation Methodology and Challenge Guidance’ document for guidance on this process.

31 If the GC or DC Breach has not been processed in time to be included in the CRA registration reports, then the Effective From Date for the CRA-estimated GC or DC value shall be set to the Working Day after next.

32 BSC Parties may elect to raise a GC or DC Estimation Challenge through the Self-Service Gateway, in which case both CRA and BSCCo will be notified, or they can email BSCCo, who will raise the GC or DC Estimation Challenge on their behalf.

33 If the CRA has two or more conflicting updates to Primary BM Unit Registration data with the same Effective From Date, it shall prioritise the updates in accordance with Section K3.4.7N and with Section K3.4.7O.

34 If the changes to the GC or DC Values has not been processed in time to be included in the CRA registration reports, then the Effective From Date shall be set to the Working Day after next.

35 The Lead Party can change an Exempt Export Primary BM Unit’s allocated Trading Unit by providing notification in accordance with BSCP31.

36 Once Exempt Export status is terminated, the Primary BM Unit’s P/C Status will no longer be fixed by the Lead Party and will be determined in accordance with Section K3.5.2.

37 The Lead Party can choose to register the Primary BM Unit in a different Trading Unit by following BSCP31.

38 Please note that the responsibility for providing accurate registration data on BSCP15/4.11 forms or in the relevant section of the Self-Service Gateway lies with the Lead Party and not BSCCo.

39 Where a CoPBLP involves multiple Primary BM Units affecting multiple Trading Units, a separate form should be used for each Trading Unit.

40 Because of the short timescales in which a Transfer of Supplier ID can occur, the Exempt Export Primary BM Unit’s P/C Status will remain unchanged on transfer to the Supplier ID Transferee unless the Supplier ID Transferee notifies the CRA/BSCCo to the contrary by following procedure 3.12.

41 The ELEXON Circular is only issued in the event of a Supplier of Last Resort (SoLR).

42 Primary BM Unit registration timescales may be reduced in certain circumstances if the registering Party agrees that the registration will not be withdrawn or amended after the ‘point of no return’

43 Typically this will be when the CFD comes to an end and the Additional Primary BM Unit is no longer required for CFD. Suppliers should ensure any MPANs are re-allocated to another appropriate Primary BM Unit. Any Metering Systems not re-allocated will be assigned to the relevant Supplier’s Base Primary BM Unit by SVAA.

44 BSCCo to initiate BSCP509 before the de-registration form is submitted to the CRA

45 Where the Primary BM Unit has a FPN set to No, the NETSO does not need to be informed of the De-Registration

46 The Supplier needs to ensure all Metering Systems associated with the additional Supplier Primary BM Unit are re-allocated to either the Base Primary BM Unit or another Supplier Primary BM Unit associated with the same GSP Group (BSCP503 & 507) unless circuits are being disconnected.

47 Notification of such Primary BM Units shall be sent to the SVAA in its capacity as the Market Domain Data manager

48 If a Secondary BM Unit De-registration is requested using Electronic File Data Transfer, the passwords and signatures are not required as the access control to the participant system is sufficient authentication. Where faxes are used, participants are required to submit hard copies of the forms by post in case the faxed signatures are illegible.

49 Where the Secondary BM Unit has a FPN set to No, the NETSO does not need to be informed of the De-Registration

50 If a BM Unit registration is requested using Electronic File Data Transfer, the passwords and signatures are not required as the access control to the participant system is sufficient authentication.

51 This information is required to help ensure the energy flow(s) for the proposed Boundary Point(s) are accounted for, where necessary (e.g. under an existing Metering Dispensation for difference metering), in the Aggregation Rules of any associated Volume Allocation Units (e.g. Interconnectors, other relevant BM Units, Grid Supply Points, GSP Groups or Distribution System Connection Points).

52 These reports would be sent if the CRA system had to be updated to reflect that change. They would not be sent if the only change was to the fuel type or the configuration of the BM Units as these parameters are not entered into the CRA system.

53 In the case of Base Primary BM Units this form should be used to complete the Base Primary BM Unit Registrations by providing, for example, the initial GC/DC values and if appropriate the FPN Flag.

54 Baselined BM Unit Indicator for Additional BM Unit Registrations only.

55 The NGC BM Unit ID must be provided for all Primary BM Units with the FPN Flag set to ‘Y’.

56 E – Embedded, I – Interconnector, G – Base Supplier S – Additional Supplier, T – Directly Connected

57 CCGT – CCGT registered in CMRS, PPM – a single Power Park Module registered in CMRS, COBMU – a Combined Offshore BM Unit comprising 2 or more Offshore Power Park Modules registered in CMRS, DC – Directly Connected Circuit at Customer (Supplied by BSC Party) Premises, DC+ – Directly Connected Circuit at Customer (Supplied by BSC Party) Premises through more than one Boundary Point, IC – Interconnector Primary Unit, BB – Primary Base BM Unit, AB – Additional Primary BM Unit, OPPM+ - Offshore PPM plus related Imports at separate Boundary Points, COBMU+ - COBMU plus related Imports at separate Boundary Points, MC – Meets criteria in BSC K3.1.2, NS – Non-Standard.

58 If unit type E or S

59 Only applicable for Interconnector Primary BM Units, which are registered in fixed Production/Consumption pairs whose P/C Status does not change (Section K3.5/K5.5). A Party applying for Exempt Export status must follow procedure 3.10 to elect the Exempt Export Primary BM Unit’s P/C Flag.
