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).

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.

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.

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.
