It is shown because two independent facts — turbine count and rated power — match the database exactly. Awaiting confirmation from a primary source.

Data sources

Wind farm data: Renewable Energy Planning Database (REPD, Department for Energy Security and Net Zero — Open Government Licence) for site attributes, and © OpenStreetMap contributors (ODbL) for turbine positions, as integrated in WhichWindTurbine. "Data not available" means the public sources do not record that attribute for this site.
