Wind Power: Finance

Asked by Harriet CrossConservativeDepartment for Energy Security and Net ZeroTabled Answered 11 June 2025UIN 57054

The question

To ask the Secretary of State for Energy Security and Net Zero, how much were constraint payments to wind farm operators in Great Britain (a) in total and (b) for each month between 1 April 2024 and 30 April 2025.

Answered by Michael Shanks

The National Energy System Operator (NESO) is responsible for operating Great Britain’s electricity system, which includes managing constraints. The NESO publishes daily constraint costs here: Constraint Breakdown Costs and Volume | National Energy System Operator. Data is not available on the split of costs between different types of generators.

Constraints are a natural part of operating an efficient electricity system and electricity systems around the world use the constraint payment model. Government is working to reduce constraints and enable a more secure energy system by accelerating the build of electricity network infrastructure to increase capacity.
