The London Array is a 175-turbine 630 MW Round 2 offshore wind farm located 20 kilometres (12 mi) off the Kent coast in the outer Thames Estuary in the United Kingdom.

It was the largest offshore wind farm in the world until Walney Extension reached full production in September 2018.

Construction of phase 1 of the wind farm began in March 2011 and was completed by mid 2013, being formally inaugurated by the Prime Minister, David Cameron on 4 July 2013.

[5] Each turbine and offshore substation is erected on a monopile foundation, and connected together by 210 km (130 mi) of 33 kV array cables.

[9] The Crown Estate awarded a 50-year lease to London Array Ltd (a consortium of E.ON UK Renewables, Shell WindEnergy, and CORE Limited[note 1]) in December 2003.

[16] Subsequently, on 16 October 2008, London Array announced the Abu Dhabi based Masdar would join E.ON as a joint venture party in the scheme.

[20] Financing of phase 1 was achieved through the European Investment Bank and the Danish Export Credit Fund with £250 million.

[25] All 175 turbines of phase 1 were confirmed fully operational on 8 April 2013,[30] and the wind farm was formally inaugurated by the Prime minister David Cameron on 4 July 2013.

[35] However, the second phase was scaled back and finally cancelled in February 2014 after concerns were raised by the Royal Society for the Protection of Birds about its effect on a local population of red-throated divers.
