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.

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.

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.
