BSC Simple Guides
The Balancing and Settlement Code (BSC) is a lengthy legal document. The following guides provide a good starting point for understanding what each part of the BSC covers.
Section S: Annex S-2: Supplier Allocation Rules
Annex S-2 sets out how the metered quantities for Metering Systems and for Supplier BM Units are determined by the Supplier Volume Allocation Agent (SVAA).
Section S: Supplier Volume Allocation
Section S and its associated Annexes set out the rules by which Supplier BM Unit Metered Volumes are determined from a combination of Half Hourly and Non Half Hourly Metering Systems. It describes the obligations on Suppliers to provide data and to ensure that Supplier Agents (i.e. certain Party Agents - principally Meter Operator Agents (MOAs), Half Hourly Data Collectors (HHDCs), Half Hourly Data Aggregators (HHDAs), Non Half Hourly Data Collectors (NHHDCs) and Non Half Hourly Data Aggregators (NHHDAs)) undertake the requirements defined for them.
Section T: Settlement and Trading Charges
Section T sets out how Trading Charges for each Trading Party and the NETSO are determined; the data required in order to calculate the Trading Charges; and the processes undertaken by the Settlement Administration Agent (SAA) in connection with the determination of the Trading Charges.
Section U: Provisions Relating to Settlement
Section U of the BSC sets out general obligations of Parties and BSC Agents relating to data and information; and provisions relating to Settlement. References in Section U to Parties do not include Elexon or Elexon Clear.
Section V: Reporting
Section V of the BSC sets out details of the Balancing Mechanism Reporting Service (BMRS) BMRS; and other reporting requirements from BSC Agents to Parties, the Authority and/or for public reporting.
Section W: Trading Disputes
Section W covers arrangements for the resolution of Trading Disputes under the BSC; arrangements for the establishment and operation of the Trading Disputes Committee (TDC); actions to be taken upon resolution of a Trading Dispute; and the effect of resolution of a Trading Dispute.
Section X – Definitions and Interpretations
Section X and its Annexes contain definitions of the terms used in the BSC and an interpretation of some of the conventions used within the BSC. It comprises Section X, which provides an interpretation of the legal standards as well as other terms and language used in the BSC together with Annex X-1: General Glossary, and Annex X-2: Technical Glossary.
Section X, Annex X-1 – General Glossary
Annex X-1 contains General Definitions: in the Code and in each Code Subsidiary Document, unless the context otherwise requires and subject to any express provisions to the contrary, the words and expressions set out in Annex X-1 shall bear the respective meanings therein set out.
Section X, Annex X-2 – Technical Glossary
Annex X-2 contains a number of technical definitions and acronyms applying within the BSC. The information is divided between those terms used only within Section S relating to Supplier Volume Allocation, and terms used throughout the remaining sections of the BSC. This is required because, for convenience, some definitions and acronyms have a different meaning between Section S and other sections of the BSC.
Section Z: Performance Assurance
Section Z of the BSC covers the establishment of the Performance Assurance Board (the PAB) - its powers and functions, the duties and responsibilities of its members, and its proceedings; performance assurance procedures; Risk Management Determination (RMD) Queries and Appeals; and the administration and implementation of Performance Assurance Techniques (PATs).
