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.

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).

Read More

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.

Read More

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.

Read More

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.

Read More

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.

Read More

P455 ‘On-Site Aggregation as a method to facilitate Third Party Access’

This Modification seeks to establish a more cost effective and efficient method for delivering Third Party Access on private networks that include domestic and small business customers. It does so by enabling aggregated meter data from sub meters on private networks to be submitted into Settlement in lieu of data from Settlement meters installed at the Boundary Point.

Read More

P454 ‘Removal of BSC obligations to provide BMRS Data via TIBCO and the High Grade Service’

This Modification would remove the existing requirement within BSC Section V ‘Reporting’ for the Balancing Mechanism Reporting Agent (BMRA) to provide BMR Service (BMRS) data via the legacy High Grade Service, otherwise referred to as the TIBCO service.

P454 is a recommendation from BSC Issue 95, which considered the impacts associated with maintaining the legacy TIBCO service.

Read More

P453 ‘Metering Dispensation process improvements and clarification to the CoPs’

This Modification seeks to progress two recommendations from Issue 93 ‘Review of the BSC metering Codes of Practice’. The first recommendation clarifies the relevant Code of Practice (CoP) for circuits embedded behind the Boundary Point Metering System or Defined Metering Point (DMP). The second recommendation eliminates the need for Metering Dispensations when the Actual Metering Point (AMP) does not coincide with the DMP, but there is no impact on Settlement accuracy.

Read More

P452 ‘Replacement of the Energy Bill Relief Scheme for non-domestic customers with the Energy Bill Discount Scheme’

This Modification seeks to enable Elexon as the Balancing and Settlement Code Company (BSCCo) to act as the payment provider for the Government’s Energy Bill Discount (EBD) Scheme for non-domestic electricity customers. This scheme will replace the existing Energy Bill Relief (EBR) Scheme.

Read More

P451 ‘Updating BSC Black Start provisions and compensation arrangements’

P451 seeks to facilitate the implementation of NGESO’s new approach to Black Start, termed System Restoration. In doing so, it proposes to update all BSC references to “Black Start” to “System Restoration”, and enable contracted Restoration Service Providers who are non-BSC parties to claim BSC Black Start compensation.

Read More

P450 ‘Housekeeping and making the BSC gender neutral’

This housekeeping Modification corrects a total of 52 non-material errors and inconsistencies across 31 Sections (including 9 Annexes) of the BSC. It also replaces gender specific references with references that are gender neutral to bring the BSC in line with modern best practice and other energy codes.

Read More

P449 ‘Non-domestic Energy Bill Relief Scheme’

This Modification seeks to enable Elexon (BSCCo) to act as the payment provider for the Government’s Energy Bill Relief Scheme for non-domestic electricity customers. The intention of the subsidy would be to reduce non-domestic consumer tariffs in light of the recent rises in energy costs. 

Read More

P448 ‘Mitigating Gas Supply Emergency Risks’

The war in Ukraine and resultant gas shortages in Europe significantly increases the risk of Generators in GB being prevented from generating this winter (due to Firm Load Shedding during a Gas Supply Emergency). If that happens Generators are likely to incur massive Imbalance Charges and credit cover requirements, potentially causing them to become insolvent. Even if such an Emergency does not occur, the risk that it could occur is likely to force Generators to reduce their forward and Day Ahead trading, reducing liquidity in electricity markets, and raising costs for electricity consumers.

Read More

P447 ‘Avoiding impact of Winter Contingency actions on cash-out prices’

This Modification would prevent negative impacts to the cash-out price if NGESO’s Winter Contingency service is used.

Read More

P446 ‘Domestic Energy Price Guarantee Scheme’

This Modification seeks to enable Elexon (BSCCo) to implement and administer the payment scheme for Suppliers as part of the Government’s Energy Price Guarantee scheme for domestic electricity customers. The intention of the subsidy would be to reduce consumer tariffs in light of the recent rises in energy costs.

Read More

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’

Read More

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.

Read More

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”.

Read More

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.

Read More

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.

Read More

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).

Read More

P438 ‘Amending the BSC to address sanction orders’

This Modification would allow Elexon to seamlessly give effect to sanctions orders.

Read More

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.

Read More

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. 

Read More

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.

Read More

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.

Read More

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. 

Read More

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). 

Read More

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.

Read More

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).

Read More

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.

Read More

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.

Read More

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.

Read More

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.

Read More

P425 ‘Single Supplier Shared SVA Meter Arrangements’

This Modification aims to reduce the requirement from two or more Suppliers, to one or more Suppliers, to be involved in a Shared Supplier Volume Allocation (SVA) Metering Arrangement.

Read More
