1 Introduction

1.1 Purpose and Scope of the BSC Procedure

This BSCP defines the key interfaces, the timetable and the responsibilities of the Applicant Party, the BSCCo, the Panel and BSC Agents when associating more than one Primary BM Unit with a Trading Unit. It does not cover the provisions of the Code relating to Primary BM Unit registration.

This BSCP is designed to ensure orderly and efficient implementation of the Code provisions relating to Primary BM Units being associated with the same Trading Unit. Every Primary BM Unit is inherently a Sole Trading Unit and in isolation requires no further authorisation. This BSCP covers the process by which Applicant Parties demonstrate conformance with the criteria for qualification for more than one Primary BM Unit being associated with a single Trading Unit.

This BSCP also describes the automatic Trading Unit allocation for Exempt Export Primary BM Units, and how the Lead Party for an Exempt Export BM Unit can change this allocation.

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.

1.2 Main Users of the BSC Procedure and their Responsibilities

This BSCP should be used by:

(a) Applicant Party

(b) BSCCo

(c) The Panel

(d) National Electricity Transmission System Operator (NETSO)

(e) Licensed Distribution System Operator (LDSO)

(f) Central Registration Agent (CRA)

(g) Lead Party seeking to change an Exempt Export Primary BM Unit's Trading Unit allocation

who are responsible for, or contribute to, the registration of a Trading Unit within the Central Registration System (CRS).

1.3 Key Milestones

The key milestone in this BSCP is the 30 Working Days notice required for the application.

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 any inconsistency between the provisions of this BSCP and the Code, the provisions of the Code shall prevail.

1.5 Associated BSC Procedures

In using this BSCP, applicants should take note of the requirements of other BSCPs, as applicable.

BSCP15 BM Unit Registration

BSCP20 Registration of Metering System for Central Volume Allocation

BSCP38 Authorisations

1.6 Trading Unit Approval (including rules for Exempt Export Primary BM Units)

Section K of the Code defines the rules under which Trading Units are approved and registered with the CRA. The Panel utilises these rules to confirm acceptance of a Trading Unit application.

With the exception of Base Trading Units, the configuration of a registered and effective Trading Unit may not change unless another application detailing the proposed changes has been made and approved. In the case of those Trading Units consisting only of Exempt Export Primary BM Units in the same GSP Group (the Class 4 Trading Units), the Panel has delegated approval to BSCCo.

All Supplier Base and Additional (non Exempt Export) Primary BM Units will automatically belong to the Base Trading Unit for the relevant GSP Group, and may not belong to any other Trading Unit.

An Exempt Export Primary BM Unit which is Embedded in a Distribution System will automatically belong to the Base Trading Unit for the relevant GSP Group, but can elect to be a Sole Trading Unit or apply to be part of a Class 4 Trading Unit or other Trading Unit in accordance with this BSCP. Elections by Embedded Exempt Export Primary BM Units to change their allocation from a Base Trading Unit to a Sole Trading Unit (or vice versa) do not require Panel approval. Applications by Embedded Exempt Export Primary BM Units to form a new Class 4 Trading Unit or other Trading Unit require approval by BSCCo or the Panel respectively, and must follow this BSCP to ensure that the necessary criteria are met. Applications by Embedded Exempt Export Primary BM Units to join or leave an existing Class 4 Trading Unit or other Trading Unit require the Trading Unit to be de-registered/re-registered as appropriate in accordance with this BSCP.

An Exempt Export Primary BM Unit which is Directly Connected to the Transmission System will automatically be a Sole Trading Unit and may not form part of a Class 4 Trading Unit. It may apply to be part of another Trading Unit in accordance with this BSCP.

Other types of BM Unit may leave a Trading Unit and become a Sole Trading Unit on application in accordance with this BSCP.

A Trading Unit application will not be valid if any Primary BM Unit which constitutes the proposed Trading Unit already belongs to any other Trading Unit other than a Sole Trading Unit (or a Base Trading Unit in the case of Embedded Exempt Export Primary BM Units).

1.7 No longer used

1.8 Impact of a Primary BM Unit’s Trading Unit Registration on its P/C Status

When in a Trading Unit with other Lead Parties, please note that changes to Generation Capacity (GC) and Demand Capacity (DC) values for other Primary BM Units within the Trading Unit can affect the overall P/C Status of the Trading Unit and thus the Primary BM Units within it.

Exempt Export Primary BM Units which have explicitly set their P/C Flag to Production or Consumption in accordance with Section K3.5 and BSCP15 are an exception, as their P/C Status will be fixed by their P/C Flag independently of their Trading Unit.

With the exception of any Exempt Export Primary BM Units in Base Trading Units which have explicitly elected to have a P/C Flag (and thereby a fixed P/C Status) of Production, all Primary BM Units in Base Trading Units will always have a fixed P/C Status of Consumption regardless of the GC/ DC values of the Primary BM Units in the Base Trading Unit. This includes all Supplier Base and Additional (non Exempt Export) Primary BM Units.

    • Letters from each Trading Unit Lead Party confirming their agreement that the Exempt Export Primary BM Units will belong to that Trading Unit.

4.2 Illustrative Diagrammatic Representations of Classes of Trading Unit

Trading Unit Class 1 Representation of a Power Station with optional additional demand fed from within the Power Station system

Trading Unit Class 2 Representation of a Power Station and demand connected by Dedicated Assets

Trading Unit Class 3 Representation of a Power Station and demand connected by Contiguous Assets

Trading Unit Class 5 Representations of:

(a) Interconnector Primary BM Units associated with the same Interconnector where such Interconnector is located at one Site only;

(b) Interconnector Primary BM Units associated with the same Interconnector where such Interconnector is located at one Site only and other BM Unit(s) connected by Dedicated Assets to one or more Boundary Points of that Interconnector; and

(c) Interconnector Primary BM Units associated with the same Interconnector where such Interconnector is located at one Site only and other Primary BM Unit(s) connected by Contiguous Assets to one or more Boundary Points of that Interconnector.

All of the diagrams in this Appendix show typical electrical configurations for different classes of Trading Unit. These diagrams are not exhaustive, but are rather intended to indicate the differences between the various Classes.

A bibliography of previously approved Trading Unit configurations is kept at the BSCCo for provision upon request.
