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.
CP1557: Housekeeping change to update CP1532 solution
The CP1532 solution is required to be updated 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 the BSCP70 and 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 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.
CP1551 ‘Measuring Instruments Regulations – updates to BSCP601’
CP1551 seeks to update BSCP601 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 that suggests a Change of Measurement Class from HH to NHH PCs 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
CP1547 ‘Clarification on Site Specific LLF Calculation Process for Embedded LDSOs’
CP1547 seeks to provide clarity for Embedded LDSOs that choose to calculate Site Specific Line Loss Factors rather than Mirroring, through updates to BSCP128.
CP1546 ‘Introducing DTC flows to transfer UMS Summary Inventories and Control files’
CP1545 ‘Introducing Technical Assurance of Metering (TAM) Central Volume Allocation (CVA) Specific Sample audits’
CP1544 ‘BSCCo Approved EFR Representative sign-off required for any EFR plan following escalation’
CP1543 ‘Use of DTC dataflow D0051 in the Half Hourly sector’
CP1542 ‘Transfer the obligation to visit de-energised sites annually from Data Collector to Supplier’
CP1541 ‘Use of D0004 in BSCP502’
CP1540 ‘Strengthening the Qualification – Change of Ownership Process’
CP1539 ‘Inclusion of LCCC as an Affected party in Metering Dispensation applications’
CP1538 Correct Specification of TERRE Tibco messages
The Assessment Report for CP1538 was presented to the ISG on 2 February 2021, where it was approved for implementation in the April 2021 ad-hoc BSC release
