Projects of 1 MW and up. Capacity is net nominal capacity (Germany) or the total capacity of the queue entry (Great Britain). A hybrid project counts under each technology it lists. Companies only: private persons are never shown as operators, and no coordinates or street addresses are published. Data as of 2026-10-25, updated monthly.
Germany: Marktstammdatenregister, Bundesnetzagentur, Datenlizenz Deutschland - Namensnennung - Version 2.0 (www.govdata.de/dl-de/by-2-0). Great Britain: Supported by National Energy SO Open Data (NESO Open Data Licence, TEC register and Embedded register).
Questions
What is in the project pipeline data?
Projects of 1 MW and up from the German Marktstammdatenregister (units in planning to decommissioned) and the GB NESO TEC and Embedded registers (queue entries with consent stage and connection date). Arcadium Data loads them monthly and records every change of stage, capacity or date.
Can I get the data as a file or through an API?
Yes. The API route /v1/energy/projects and the MCP tool energy_projects return the same projects with filters for country, technology, stage, capacity and changes since a day; the whole dataset can be licensed as files.
