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
Both of the first phases have 51

Construction
In 2004 DONG Energy was awarded a 50-year lease from
The project involved constructing the wind turbines and their
Walney 2 began sending power to the grid on 1 November 2011. In February 2012, DONG Energy claimed to have installed the 51 turbines in Walney 2 in 5 months and 14 days, including monopiles and complete turbines; about 3.25 days per turbine. Walney 1 took 7 months. The improvement is due to commonality of projects and resources.[16] The wind farm was officially opened on 9 February 2012 by the new energy secretary, Ed Davey, MP,[5] although the last of the 51 turbines in Walney 2 were only activated in April 2012.[17]
Walney Extension
In November 2014 DONG Energy was given development consent for an extension to the Walney offshore wind farm.[18] The development consent allowed a maximum of 207 turbines to be added to the existing 102 turbines.[18] The maximum generating capacity of the extension was said to be 750 MW although DONG was reported to be proceeding with a project based around 660 MW.[18] Offshore construction began in 2017, onshore support construction having started in 2015.[11] In 2015 DONG chose the 8 MW Vestas V164 for Phase 1,[19] and the 7 MW Siemens gearless turbine for Phase 2.[20] In April 2018, the final turbine of the 87 installed for Phase 1 was completed, with full operation commencing in September 2018.[21]
Incidents
In 2014 a dive vessel, owned by Danish firm Offshore Marine Services, was carrying out routine inspection work when an anchor cable broke and the ship hit one of 102 turbines installed at the Walney Offshore Wind Farm. The UK’s Maritime and Coastguard Agency surveyed the crash site and reported that a surface sheen stretching 33 feet wide and 0.7 nautical miles long was trailing the vessel. The agency said that, unlike heavier crude oil, the marine engine oil should evaporate or disperse naturally.[22]
