List of all BSC Modifications
P445 Improving efficiency of Default Funding Share process and Energy Supply Company Administration
This Modification seeks to allow the Funds Administration Agent (FAA) to process a Default Funding Share for unpaid Trading Charges earlier to reduce the cost of the borrowing facility and reduce the risk of shortfall. The Modification will also allow the Panel to instruct the FAA to release Trading Charges where the default relates to an Energy Supply Company Administration (ESCA).
P444 Compensation for Virtual Lead Party actions in the Balancing Mechanism
P443 To Cap NGESO Interconnector Trades
At the current time National Grid Electricity System Operator (NGESO) can trade at prices above the Value of Lost Load (VoLL – as defined in BSC Section T 1.12, currently set at £6,000/MWh). The Proposer’s view is that this adds to customers’ costs and sends a signal to the markets that customers are willing to buy power at any price. In a cost of living crisis the Proposer does not believe that the British public are prepared to buy energy at any price.
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.
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 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).
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.
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
P429 will permanently cease the operation of, and remove the obligations associated with, participant-reported Performance Assurance Reporting and Monitoring System (PARMS) Serials and associated Supplier Charges.
P428 Correction to P376 Legal Text
This Modification is required to correct an error contained within the approved legal drafting for P376. This Proposal will ensure that Virtual Lead Parties (VLPs) do not need to submit the status of Metering System Identifier (MSID) pairs contained within secondary Balancing Mechanism (BM) Units that do not use the baselining methodology introduced in the P376 solution.
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.
P426 Combining related BSC Parties’ Energy Indebtedness positions for the Credit Cover Percentage calculation
This Modification proposes to remove inefficiencies with the Credit Cover calculation by allowing related BSC Parties to combine their Energy Indebtedness prior to calculating the Credit Cover Percentage.
