P440 ‘Enabling Elexon to administer the Capacity Market Advisory Group’
The BSC does not currently allow Elexon to undertake administrative activities that would support the Capacity Market Advisory Group (CMAG). This does not align to Ofgem’s decision to appoint Elexon to undertake the CMAG administrative activities on its behalf.
P439 ‘Enabling EDA-based Data Integration Platform Development’
This Modification makes changes to the Balancing and Settlement Code (BSC) to enable Elexon, in its capacity as the Market-wide Half Hourly Settlement (MHHS) Implementation Manager, to develop the Event Driven Architecture (EDA) based system for MHHS, which will be known as the Data Integration Platform (DIP).
P438 ‘Amending the BSC to address sanction orders’
This Modification would allow Elexon to seamlessly give effect to sanctions orders.
P437 ‘Allowing non-BSC Parties to request Metering Dispensations’
This Modification proposes to introduce a provision in Section L ‘Metering’ to allow the relevant Meter Operator Agent to apply for Metering Dispensations on behalf of a non-BSC Party.
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.
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 running from October 2023 to October 2024. It will also require all new UMS connections to be settled Half Hourly (HH) from October 2023.
P433 ‘P375-P420 Legal Text Alignment’
P433 seeks to ensure that the Legal Text for Approved Modification P375 ‘Settlement of Secondary BM Units using metering behind the site Boundary Point’ is aligned with the BSC baseline introduced by the implementation of P420 ‘Retail Code Consolidation Significant Code Review’. 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’
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).
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.
