Wind farm layout

Walney Wind Farms are a group of offshore wind farms 9 miles (14 km) west of Walney Island off the coast of Cumbria, England, in the Irish Sea. The group, operated by Ørsted[1] (formerly Dong Energy), consists of Walney Phase 1, Phase 2 and the Walney Extension. The extension has a capacity of 659 MW[2] and it was the world's second largest offshore wind farm in 2018.[2]

The wind farms were developed by Walney (UK) Offshore Windfarms Limited, a partnership between DONG Energy and Scottish and Southern Energy.[3] The farms, which are immediately northwest of the West of Duddon Sands Wind Farm and west of Ormonde Wind Farm, are in water depths ranging from 19m to 23m and cover an area of approximately 73 km2.

Both of the first phases have 51 turbines giving a nameplate capacity of 367 MW.[4] Until September 2012 it was the world's largest operational offshore wind farm, and regained this title when the expansion completed in September 2018.[5][2] The first two phases were expected to generate about 1,300 GW·h/year of electricity, with a load factor of 43%.[6][7] The Walney Extension opened in September 2018 with a further 87 turbines capable of generating 659 megawatts.[8] And the area reaches 145 km2.
