The project was originally developed by Greater Gabbard Offshore Winds Limited (GGOWL) which was a joint venture between Airtricity and Fluor. Airtricity was subsequently bought by Scottish and Southern Energy who have bought out Fluor's 50% stake for £40m which is expected to cost £1.3b. Fluor are now contracted to design, supply, installation and commissioning of the balance of the plant. Scottish and Southern sold a 50% stake to RWE in November 2008 for £308m who are the owners of Npower (UK).

The project was given the go-ahead in May 2008.
In October 2009 Seajacks Ltd delivered its 7,000 tonne Leviathan vessel to Fluor Ltd which will sailed to Harwich to prepare the hook-up and commissioning of an in-field substation and then installation of the turbines. The first pontoons were installed in autumn 2009 with the first of a total of 140 turbines to be installed in the spring 2010. Construction is expected to be completed in 2012.
