It has 114 turbines of 10 MW each (9.2 in the REPD), a capacity of 1,075 MW; the site sits 30 km from the nearest postcode in Aberdeenshire, with DD10 (Montrose) 33.0 km away.
238 weeks to consent
SSE and Seagreen Wind Energy Ltd submitted the application on 23 October 2012. The register dates the marine licence and the Section 36 consent (Marine Scotland as the authority) to 16 May 2017, more than four times the median of 56.6 weeks. On that same day the Court of Session reinstated the consent granted by Scottish Ministers, which RSPB had challenged; Inch Cape shares that date, under construction 22.5 km away at 1,080 MW. The Contract for Difference came in round AR3, construction ran from 1 May 2021, and the wind farm has been operational since 16 October 2023.
