List of all BSC Change Proposals
These pages list all Change Proposals (CP) issued since 2010. These are detailed proposals which are raised to amend CSDs and/or BSC Systems, but would not alter the BSC. They must have a clear aim, a single defined solution and contain the relevant redlined documentation changes.
CP1567 ‘New BSC Procedure (BSCP) for Assurance Information Requests (AIRs)’
The AIR is a Performance Assurance Technique (PAT) which was introduced in May 2022. Currently there is no related BSCP for an AIR, therefore when issuing an AIR, there is no written obligation on Parties to adhere to the request.
CP1566 ‘Introducing the CVA Commissioning End to End Check (CEEC) process’
CP1566 seeks to formalise the Central Volume Allocation (CVA) Commissioning End to End Check (CEEC) process in BSCP02, BSCP20, BSCP38, CoP4 and CDCA Service Description for new and existing CVA Metering Systems.
CP1565 ‘Updates to address Central Management System issues’
This CP seeks to update BSCP520 to contain clearly outlined processes for approval and fault reporting of Central Management Systems.
CP1564 ‘Amendments to the approved IDD spreadsheets for P399’
CP1564 is a Housekeeping change seeking to update the the New Electricity Trading Arrangements (NETA) Interface Definition Documents Part 1 and 2 that were approved under P399 ‘Making the identity of Balancing Service providers visible in the Balancing Services Adjustment Data’ to correct a defect impacting sub-flows 3 & 4 of the SAA-I014 Settlement Reports.
CP1563 ‘Altering the Trigger Point and subsequent Timescales for Commissioning SVA CT Operated Metering Systems and issue of Data Flow’
CP1563 seeks to update some of the trigger points for Current Transformer (CT) Commissioning and subsequent sending of data flows as the Proposer considers that they are not appropriate for CT operated metering systems of all types.
CP1562 ‘Amendments to the approved IDD changes for P375’
CP1562 seeks to update the New Electricity Trading Arrangement (NETA) Interface Definition Documents(IDD) Part 1 and 2 that were approved under P375, to provide clarity to the relevant Parties that make use of the document.
CP1561 ‘Updating SVA DC Volume 1 and 2 for CP1546’
CP1561 looks to update the Supplier Volume Allocation (SVA) Catalogue Volume 1 and 2 to include the approved data flows and data items from CP1546.
CP1560 ‘Demand Control Event Process Clarifications’
This CP seeks to clarify the processes that take place after a Demand Control Event by amending the relevant Code Subsidiary Documents to ensure clarity and consistency.
CP1559 ‘Complex Sites Process Improvements’
This Change Proposal will deliver improvements to the Complex Sites process.
CP1558 ‘New Registration data items to facilitate MHHS’
This Change Proposal will introduce new Registration Service data items and supporting BSC processes into existing Supplier Meter Registration Service (SMRS) systems.
CP1557: Housekeeping change to update CP1532 solution
CP1557 makes non-material changes to update the CP1532 solution to reflect changes made to BSCP502 ‘Half Hourly Data Collection for SVA Metering Systems Registered in SMRS’ following the implementation of P420.
CP1556 ‘Improving the CVA Qualification Testing experience for VLPs and AMVLPs’
CP1556 looks to update BSCP70 ‘CVA Qualification Testing for Parties and Party Agents’ and the Communication Requirements Document to include a test request process and a list of P-flows for VLPs and AMVLPs.
CP1555 ‘Consumption data for Measurement Classes G and F’
This CP proposes to update the requirements in BSCP502 to require HHDCs to send D0036 or D0275 for non-Data Communications Company (DCC) enrolled Metering Systems and/or D0380 for DCC enrolled Metering Systems to Licenced Distribution System Operators (LDSOs).
CP1554 ‘Future proofing the measurement transformer standards’
CP1554 looks to future proof the measurement transformer standards in Code of Practices 1, 2, 3, 4, 5 and 10
CP1553: Meters and Current Transformers minimum accuracy classes
This Change proposal looks to tighten the requirements for Meters and Current Transformers in the Code of Practice.
CP1552 ‘Reflecting BSCP501 timeframes in BSCP520 processes’
CP1552 seeks to provide clarity to market participants about the timeframes for various processes in BSCP520 ‘Unmetered Supplies Registered in SMRS’.
CP1551 ‘Measuring Instruments Regulations – updates to BSCP601’
CP1551 seeks to update BSCP601 ‘Metering Protocol Approval and Compliance Testing’ so it aligns with new Government legislation for new Meters being placed on the GB market.
CP1550: Updates to monitoring of voltage failure alarms requirements
This Change Proposal looks to simplify the management of phase failures and update the requirements of voltage failure alarms.
CP1549 ‘Amendment of BSCP516 to clarify the criteria for Non-Domestic SVA Metering Systems’
CP1549 seeks to remove the text from BSCP516 ‘Allocation of Profile Classes and SSC’s for Non Half Hourly SVA Metering Systems Registered in SMRS’ that suggests a Change of Measurement Class from HH to NHH Profile Classes 3 or 4 is not possible so that it aligns with the correct interpretation of the rules set out in the BSC.
CP1548 ‘Remove constraint requiring BMRS to publish data files in a specific CSV format and structure’
This change proposal, CP1548, seeks to remove the specification of particular download formats in NETA IDD Part 1 Document paragraph 4.13 and be housed and maintained in the BMRS API and Data Push User Guide
