In the full datasetThis ranking covers 244 companies ordered by attributed renewable capacity in United Kingdom. The top 10 alone account for 49.2 GW — 64% of the 76.9 GW tracked across the whole list — so the file shows you both the giants and the long tail of regional developers behind them.
Every company carries its operating and pipeline megawatts, technology split and project countries, rolled up from Global Energy Monitor's project trackers (used under CC BY 4.0) and enriched with company data from public sources: 100% have a website, 68% a company email and 30% a phone number.
Ownership is attributed share-weighted per project, so joint ventures are not double-counted, and subsidiaries keep their own aggregates. Use the technology and country columns to cut the ranking to exactly the renewable-energy exposure you care about.
