Greater Gabbard is a 504 MW wind farm, built on sandbanks 23 kilometres (14 mi) off the coast of Suffolk in England at a cost of £1.5 billion.

[5] The project was originally developed by Greater Gabbard Offshore Winds Limited (GGOWL) which was a joint venture between Airtricity and Fluor.

[6] Scottish & Southern sold a 50% stake to RWE, the owners of Npower, in November 2008 for £308m.

[8] In July 2011 erection of the turbines was two-thirds complete, with all the pile foundations installed.

In October 2009, Seajacks Ltd delivered its 7,000 tonne Leviathan vessel to Fluor Ltd which sailed to Harwich to prepare the hook-up and commissioning of an in-field substation and then installation of the turbines.

[14] In October 2014 Innogy announced that it too was abandoning the project,[15] but in December the company revealed that it was still seeking potential investment partners.

It is owned by Innogy SE (25%), Siemens Financial Services (25%), Sumitomo Corporation (12.5%), ESB (12.5%) and a consortium managed by Green Investment Group and Macquarie Infrastructure and Real Assets (25%).
