This page shows which Modifications and Change Proposals have been identified as impacting a Licensed Distribution Systems Operator. Please note that the assessment of where impacts may affect certain roles within the electricity market may be amended during the course of the Change 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.
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.
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.
P434 ‘Half Hourly Settlement for UMS Metering Systems’
This Modification will require a period of mandatory Change of Measurement Class (CoMC) activity for all Non-Half Hourly (NHH) Unmetered Supplies (UMS) Metering Systems running from October 2023 to October 2024. It will also require all new UMS connections to be settled Half Hourly (HH) from October 2023.
P427: Publication of Performance Assurance Parties’ impact on Settlement Risk
This Modification seeks to amend BSC Section Z to allow the Performance Assurance Board (PAB) to recommend that the Panel publish notices to industry in respect of Performance Assurance Parties’ (PAPs’) contribution to Settlement Risk along with relevant risk data.
P432 ‘Half Hourly Settlement for CT Advanced Metering Systems’
This Modification proposes to align the BSC definition of an Advanced Meter with that in the Standard License Conditions (SLC) and to set explicit Half Hourly (HH) Settlement obligations for Current Transformer (CT) Advanced Meters ahead of the migration to Market-wide Half-Hourly Settlement (MHHS).
CP1563 ‘Altering the Trigger Point and subsequent Timescales for Commissioning SVA CT Operated Metering Systems and issue of Data Flow’
CP1563 seeks to update 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.
P438 ‘Amending the BSC to address sanction orders’
This Modification would allow Elexon to seamlessly give effect to sanctions orders.
P436 ‘Consequential BSC changes for Switching SCR (REC 3.0)’
Ofgem’s Switching Significant Code Review (SCR) will introduce the new Central Switching Service (CSS) and version 3.0 of the Retail Energy Code (REC 3.0). P436 progresses the consequential BSC changes needed to align with REC 3.0.
