BSC Procedures (BSCPs)

The purpose and scope of this BSCP is to enable Third Party Generators to centrally register Third Party Generating Plant (typically embedded generators) such that the Exports of such Third Party Generating Plant can be traded in the Balancing Mechanism without having to go through a Licensed Supplier.

This requires the registration of Metering Systems to be transferred between SVA (utilising the Supplier Meter Registration Service – SMRS) and CRA (utilising the Central Meter Registration Service – CMRS) and for checks to be made to ensure that energy is accounted for in one system but not in both Registration systems.

Known as “Registration Transfers”. For Settlement purposes this means that each part (i.e. the Import or the Export) of the Third Party Generating Plant is accounted for in Central Volume Allocation or Supplier Volume Allocation but not both for any particular Settlement Day.

This BSCP defines the key interfaces, interdependencies and timetable for the CVA Qualification Testing for Parties and Party Agents as required by Section O of the Balancing and Settlement Code (BSC), and the Communication Requirements Document.

The purpose of this BSCP is to enable the submission of Energy Contract Volume Notifications (ECVNs) and Metered Volume Reallocation Notifications (MVRNs) to the Energy Contract Volume Aggregation Agent (ECVAA). It describes the process for submitting notifications, and replacing previously submitted notifications.

This BSCP defines the process for submission of Aggregation Rules by Parties to the Central Data Collection Agent (CDCA) for Volume Allocation Units as defined in Section R of the Code. This describes the key interfaces and timetable responsibilities for interested parties. It  defines the process for the Lead Party of Primary BM Units in a Switching Group to instruct CDCA to use a different set of Aggregation Rules to reflect the switching of Plant and Apparatus between Primary BM Units. This does not include the registration of Aggregation Rules for Supplier Primary BM Units. The Virtual Lead Party are not required to register Aggregation Rules for Secondary BM Units.

This BSC Procedure (BSCP) defines the procedure by which Line Loss Factor (LLF) methodologies submitted by Licensed Distribution System Operators (LDSOs, including Host LDSOs and Embedded LDSOs) are reviewed by BSCCo, presented to the Panel for approval and, where appropriate, reported to the Performance Assurance Board (PAB).

This appendix relates to the Methodology of Self Assessment Document (MSAD) for Host LDSOs and Embedded LDSOs that do not Mirror and is part of BSCP128 which deals with Production, Submission, Audit and Approval of Line Loss Factors.

This appendix relates to the Methodology of Self Assessment Document (MSAD) for Host LDSOs and Embedded LDSOs that Mirror and is part of BSCP128 which deals with Production, Submission, Audit and Approval of Line Loss Factors.

BSCP128 Appendix 3 defines the procedure by which Line Loss Factor methodologies submitted by Licensed Distribution System Operators (LDSOs, including Host LDSOs and  Embedded LDSOs) are reviewed by BSCCo, presented to the Panel for approval and, where appropriate, reported to the Performance Assurance Board.

This appendix relates to the Calculation Self Assessment Document (CSAD) for Host LDSOs and Embedded LDSOs that Mirror and is part of BSCP128 which deals with Production, Submission, Audit and Approval of Line Loss Factors.

This appendix relates to the CSAD 2.1 and 2.2 tables for all Host and Embedded Submissions and is part of BSCP128 which deals with Production, Submission, Audit and Approval of Line Loss Factors.

This appendix relates to the CVA Long and Short Format data files and is part of BSCP128 which deals with Production, Submission, Audit and Approval of Line Loss Factors.

This appendix relates to the SVA Format data file (D0265) and is part of BSCP128 which deals with Production, Submission, Audit and Approval of Line Loss Factors.

This appendix relates to the SVA Summary Report and is part of BSCP128 which deals with Production, Submission, Audit and Approval of Line Loss Factors.

This appendix relates to the Site Specific LLF Calculation Audit Evidence Template and is part of BSCP128 which deals with Production, Submission, Audit and Approval of Line Loss Factors.

This appendix relates to the Calculation Self-Assessment Document (CSAD) for mid-year LLF submissions and is part of BSCP128 which deals with Production, Submission, Audit and Approval of Line Loss Factors.

BSCP201 describes the steps to be taken during and following a Black Start Period or a Fuel Security Code event, and supports the rules set out in BSC Section G ‘Contingencies’. It includes the steps required to restore normal BSC market operations, if these have been suspended during a Black Start. It also includes the steps required for BSC Parties to optionally raise claims for excess costs in certain circumstances. It highlights the responsibilities and actions required by industry participants to ensure this is done efficiently and effectively.

BSCP301 defines the processes that the Funds Administration Agent (FAA) shall use to carry out the transfer of funds in respect of Settlement between Parties and the Code Clearer for Trading Charges, Ad Hoc Trading Charges and Reconciliation Charges under the Code, and some ancillary activities. It also defines the processes by which Parties may reduce or increase the amount of Credit Cover held by the FAA in relation to that Party.

This BSCP defines those activities which enable the Supplier Meter Registration Service (SMRS) to fulfil its functions to:

Provide Suppliers with information relating to their MSIDs; provide Half Hourly Data Aggregators with MSID information; Non Half Hourly Data Aggregators with MSID information; receive and process Supplier data; Bulk Change of Non Half Hourly Supplier Agent; receive and process Licensed Distribution System Operator data; receive and process Market Domain Data; enable Transfers of Registrations between SMRS and CMRS; enable new connections where the same Metering Equipment at an Exemptable Generating Plant is comprised in both an SVA Metering System and a CVA Metering System, where Export Active Energy is traded in CVA and Import Active Energy is traded in SVA; record BSCCo Required Data.

This BSCP defines the processes that the Half Hourly Data Collector shall use to carry out the work for data collection (including data retrieval, estimation and data processing) for SVA Metering Systems with half hourly (HH) Metering Equipment operating within the Supplier Volume Allocation (SVA) arrangements.

This BSC Procedure defines the processes that the Half Hourly Data Aggregator (HHDA) shall use for data aggregation for SVA Metering Systems with Half Hourly (HH) SVA Metering Equipment. This BSC Procedure focuses on the interfaces between the HHDA and other Agencies seen from the perspective of the HHDA.
