Renewable Generators

Wind Farm Constraint Payments

List of the constraint payments to wind farms via the Balancing Mechanism to reduce output during grid constraints. 

Renewable Energy Built and In Planning

21 January, 2025: The full update of all the datasets has been supported by a generous legacy from the estate of the late Mr Simon Pearson for the promotion of research into renewable energy solutions.

Bespoke data service: The Renewable Energy Foundation is pleased to offer a bespoke data query service of its extensive largely-unpublished databases through its consultancy arm, Renewable Energy Forum. Potential clients should note that both Renewable Energy Foundation and Forum have large databases with information on renewable and non renewable energy generation, and planning applications and appeals, and is a licensed user of the Elexon electricity market database.
