Sources and method
Figures come from the July 2026 extract of the Department for Energy Security and Net Zero's Renewable Energy Planning Database (REPD), which tracks UK renewable projects through planning, construction and operation. Each figure is calculated directly from the source records and refreshes when a new snapshot is imported.
The REPD counts project records, not physical sites. Extensions, repowering schemes and later phases can appear as separate records, and very small turbines below the database threshold are not included. Status reflects the snapshot date; developers' later announcements can differ. Read the full methodology and limitations.
