Erebus floating offshore wind farm
Erebus Floating Offshore Wind Demonstration Project is a 100 MW floating offshore wind farm with 10 turbines in Welsh waters. Its status in the Renewable Energy Planning Database (July 2026 extract) is: approved on 17 February 2023, not yet built; the record was last updated on 19 January 2026. REPD gives a grid reference on the coast (SA71 5DP, Pembrokeshire), not the position of the turbines, so the distance out to sea is not known from REPD. It is decided by the Welsh Government as a development of national significance.
