List of all BSC Modifications
P442 ‘Reporting chargeable volumes for exempt and licensed supply’
This Modification seeks to allow correct reporting of chargeable volumes to the EMRS company for SVA Metering Systems that record both exempt supply and licensed supply through the addition of a new third party role, the “Exempt Supply Notification Agent”.
P441 ‘Creation of Complex Site Classes’
This Modification looks to progress a recommendation of the Issue 88 Workgroup to introduce Complex Site classes. These classes would categorise the types of Complex Site, each having clearly defined criteria within the BSC. A new “type” of Complex Site (referred to as a Class 6 Complex Site) to allow approval of ”non-standard” complex sites would also be introduced.
P441 would also clarify when the netting of Imports from Exports for multiple Metering Systems registered in Supplier Volume Allocation (SVA) is permitted.
This change would facilitate consistency across the market and as so called “Local Energy Schemes” become more popular, rules for when netting are permitted would be clearly defined going forward.
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 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 2024. It will also require all new UMS connections to be settled Half Hourly (HH) from 12 months prior to M11, currently 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.
