List of all BSC Modifications
These pages list all Modifications issued since 2001. Modifications are raised to introduce changes that would alter any part of the BSC or any Code Subsidiary Documents (CSDs) or BSC Systems impacted by the proposed changes.
P465 ‘Correction to P415 legal text to amend Credit Cover requirements for Virtual Trading Parties’
This Modification is required to correct an error in the approved legal drafting for P415. This Proposal will ensure that Credit Cover requirements for Virtual Trading Parties (VTPs) correctly take into account the energy volumes (‘Deviation Volumes’) that VTPs trade in wholesale markets, which was the intention of the P415 Workgroup.
P464: ‘Housekeeping and updating BSC references to “Consumer Scotland”, “Generation Curtailment Validation Committee” and “GCVC”’
This housekeeping Modification proposes to replace any references to “Citizens Advice Scotland” with “Consumer Scotland”. It also proposes to replace any references to “Network Gas Supply Emergency Settlement Validation Committee” and “NGSESVC” to “Generation Curtailment Validation Committee” and “GCVC”. Additionally, it also proposes to correct 5 non-material errors and inconsistencies across 5 Sections of the Balancing and Settlement Code (BSC).
P463 ‘Introduce a Standard Change Process’
To introduce a new change process – a ‘Standard Change’ process – into the BSC arrangements that would allow for certain, low risk, predictable and repeatable pre-authorised changes to be implemented without following the existing Change Proposal or Modification procedures.

P462 ‘The removal of subsidies from Bid Prices in the Balancing Mechanism’
This Modification aims to reduce consumer cost potentially caused by the interaction between the BM and support mechanism arrangements. This shall be done by removing distortion of support mechanisms (such as Contracts for Difference (CfDs) and the Renewables Obligation (RO) schemes) to reduce actions being taken outside of consumer cost order when following the Bid stack merit order.
The proposed solution for consideration by an industry Workgroup is to modify the equation BSC Section T ‘Settlement and Trading Charges’ paragraph 3.11 to pay the lost support mechanism.
P461 ‘Accurate Reporting of Customers Delivered Volumes to Suppliers’
The details reported to Suppliers when a customer delivers a Bid Offer Acceptance (BOA) through a Virtual Lead Party (VLP) do not reflect any adjustments made to that data in Settlement. This Modification proposes to address this issue by amending the values reported to Suppliers.
P461 is currently in Report Phase Consultation. This closes at 5pm on 18 December 2023.
Elexon welcomes views from interested Parties.
Please see the Report Phase Consultation and questions below.
P460 ‘Amend the responsibility to propose and consult on a MHHS Migration Plan’
P460 aims to change responsibility for proposing, consulting on and obtaining approval of the Market-wide Half Hourly Settlement (MHHS) Migration Plan from BSCCo to the Market-wide Half Hourly Settlement Programme (MHHSP).
P459 ‘Allowing different Supplier Agents to be appointed to Import and Export MSIDs’
This Modification would allow Suppliers to appoint different Supplier Volume Allocation (SVA), Meter Operator Agents (MOAs) and Data Collectors (DCs) for the Import and Export Metering System Identifiers (MSIDs) where Data Communications Company (DCC) adopted smart meters are installed. Being able to appoint different Supplier Agents across Import/Export MSIDs will remove a barrier preventing the use of Export MSIDs for small-scale micro-generation, which currently disbenefits Suppliers, sales and operators of micro-generation, and electricity consumers.
P458 ‘Introducing Data Controller and Processor Obligations in the BSC for MHHS Testing’
The purpose of this Modification is to address the need for personal information sharing in the Balancing and Settlement Code (BSC), specifically in the context of the Market-wide Half Hourly Settlement (MHHS) testing. The current BSC General Data Protection Regulation (GDPR) and data protection provisions were not designed to allow the sharing of personal information, which has now become necessary for the planned MHHS testing.
P457 ‘Replace the Electricity Arbitration Association with the London Court of International Arbitration’
P457 proposes to remove the Electricity Arbitration Association (EAA) from the BSC and replace with the London Court of International Arbitration (LCIA) to deliver better value for money and service.
P456 ‘Enable Elexon to procure ancillary Technology Services for use by BSC Agents’
Removing barriers in BSC Section E that would prevent Elexon updating BSC Agent contracts, therefore enabling BSC Agents to use Technology Services procured by Elexon. This should reduce costs for BSC Parties.
