This page shows which Modifications and Change Proposals have been identified as impacting the National Electricity Transmission System Operator (NETSO). Please note that the assessment of where impacts may affect certain roles within the electricity market may be amended during the course of the Change process.
P424 Re-insert correct definition of Settlement Error
P416 Introducing a route of appeal for the Annual Budget in line with the proposals for the Retail Energy Code
P416 seeks to amend the BSC to include an appeals mechanism that BSC Parties could use to challenge items in the Annual Budget.
P375 ‘Settlement of Secondary BM Units using metering behind the site Boundary Point’
P375 will allow Metering Equipment situated ‘behind’ the defined Boundary Point to be used for Settlement purposes in place of the Boundary Point Meter. Primarily, this will allow balancing-related services on-site from smaller assets to be separated from current imbalance-related activities, more accurately reflecting the balancing-energy volumes provided by the Balancing Service Provider (BSP).
P438 Amending the BSC to address sanction orders
This Modification would allow Elexon to seamlessly give effect to sanctions orders.
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).
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.
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.
CP1576 New Interconnector Fuel Type Category: Viking Link
Changes are needed to the Balancing Mechanism Reporting Service (BMRS) to ensure data relating to the new Viking Link Interconnector is provided to market participants alongside existing data relating to Settlement arrangements in the Great Britain (GB) electricity market.
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.
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.
