In 2002 the UK government designated the Greater Wash strategic area as potential offshore wind farm development region.

[4] The proposed wind farm covered an area of 75 square kilometres (29 sq mi) at water depths of 4 to 22 metres (13 to 72 ft).

[5] In July 2012 the government gave planning approval for Centrica to construct a wind farm to the capacity of 580 MW.

[11] The new substations were to be supported on four-legged jacket foundations secured to the sea floor with pin piles;[12] as a consequence of the change the number of export cables was to be reduced to two.

[14] In June 2014 Dong committed to building the wind farm, which was to receive subsidies under the Renewables Obligation scheme (1.8 ROCs per MWh).
