The application covers the array site for up to 144 turbines northwest of Islay and west of Colonsay, with a total capacity of 2 GW and expected output equivalent to powering two million homes. Separate consent applications for the offshore export cable corridor and onshore transmission infrastructure will be submitted later. It is the second ScottishPower Renewables ScotWind project to reach consent submission this year, following the 3 GW MarramWind floating project's applications filed earlier in 2026.
