To ask the Secretary of State for Energy Security and Net Zero, which companies have received curtailment payments; and what those payments were in each year since 2015.

The Department does not hold this information. The National Energy System Operator (NESO) is responsible for managing constraints and publishes yearly breakdowns by cost and volume, which can be found here: Constraint Breakdown Costs and Volume | National Energy System Operator. This is aggregate data and does not show which companies have received constraint payments.

Increasing the capacity of Great Britain’s electricity network is essential for reducing curtailment and constraint payments. This is why the Government is working to accelerate the build of new network infrastructure, so more cheap, homegrown energy can power up our homes and businesses.
