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.
CP1555: Consumption data for Measurement Classes G and F
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 from BSCP516 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.
