Dounreay Trì floating offshore wind farm
Dounreay Trì Floating Wind Demonstration is a 10 MW floating offshore wind farm with 2 turbines in Scottish waters. Its status: not going ahead: the consent holder, Highland Wind Limited, states that the offshore part of the Dounreay Trì consent is no longer being implemented; the site is used for the Pentland Floating Offshore Wind Farm instead (Highland Wind Limited). The Renewable Energy Planning Database (July 2026 extract) still records: under construction since 31 March 2017; the record was last updated on 6 December 2019. Its REPD grid reference is 15 km from the nearest postcode on land (KW14 7YN, Highland). As an offshore wind farm in Scottish waters, it is consented by Scottish Ministers; REPD names Marine Scotland as the consenting authority.
