An open European offshore wind turbine database for mesoscale modelling of European offshore wind farms is presented, containing all operating wind farms as of commissioning date before 2026-01-27. The approach integrates turbine locations from the OpenStreetMap [1] and EMODnet [2] with metadata on turbine and wind farm properties from additional public sources. The turbine information is augmented with generic thrust and power curves calculated via the pyWake [3] turbine generator [4]. The database will be updated continuously; changes to the previous version of the dataset from August 2025 are documented in the log_update_20260127.txt file.
