SSE Renewables has filed a planning application for the 4.1GW Berwick Bank offshore wind farm off the east coast of Scotland in the North Sea.
The developer is seeking permission from Marine Scotland to build 307 turbines with either suction caisson or piled jacket foundations.
Each turbine would have a maximum rotor blade tip height of 355 metres, rotor blade diameter of 310 metres and a maximum hub height of 200 metres. The project will require up to 1,225km of inter-array cabling.
SSE also wants the green light to build up to 10 offshore substation platforms or converter station platforms in the proposed development area, connecting to each other via as many as eight interconnector cables.
Power from the wind farm would then be transmitted 47.6km to the East Lothian coastline at Skateraw Harbour via as many as eight offshore export cables, according to the application.
An additional export cable to Blyth in northeast England is also being developed, agreed between the developer and National Grid ESO in June 2022 that is required for the project to reach its full generating capacity.
Consent for this line will be applied for separately once further development work has been completed.
SSE has meanwhile made a Derogation Case as part of its application to satisfy Habitats Regulations. There is potential for adverse effects on the integrity of eight sites supporting populations of kittiwake, as well as one or more on guillemot, razorbill and puffin.
The developer aims to bring the full project online by the early 2030s.
