List of all BSC Modifications
P435 Enabling EMRS to undertake preparatory work for potential future settlement services to LCCC
This Modification proposes to extend Elexon Vires through its wholly-owned subsidiary company Electricity Market Reform Settlement (EMRS) Limited.
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 to complete before the Market Wide Half Hourly Settlement (MHHS) migration to the Target Operating Model (Milestone 11 (M11) in the MHHS Timetable). At the time of writing, this would need to complete by October 2025. It will also require all new UMS connections to be settled Half Hourly (HH) from 12 months prior to M11, currently October 2024 (post CR055 decision).

This Modification will correct a number of manifest errors introduced into the P375 legal text by P420 and will therefore allow the implementation of the P375 Legal Text in the BSC on the P375 Implementation Date.
P432 Half Hourly Settlement for CT Advanced Metering Systems

P431 Post Brexit Agreement Updates
As a result of the UK leaving the EU, Great Britain (GB) is no longer part of the Internal Energy Market and updates are required to the BSC to ensure that the legal text appropriately reflects these changes.
P430 Extension of P375 to include Suppliers
P430 seeks to extend the solution to Approved Modification P375 ‘Settlement of Secondary BM Units using metering behind the site Boundary Point’ to allow Suppliers to register Asset Meters and allocate Asset Metering System Identifier (AMSID) Pairs to Secondary Balancing Mechanism Units (SBMUs).
P429 Switching off Participant-Reported PARMS Serials

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.

P418 aims to ensure the Legal Text for approved BSC Modification P383 properly reflects the approved solution, business requirements, and is aligned with the BSC baseline introduced by P344, P354 and P388. In particular, it will clarify that the solution being delivered by P383 is applicable to both Supplier Base Balancing Mechanism (BM) Units and Additional BM Units.
