The energy giant E.ON has been given approval from the Government to build a 230-megawatt wind farm in the North Sea, five miles off the Yorkshire coast.
Once fully operational, the Humber Gateway installation will have the capacity to provide power for up to 150,000 homes from 77 turbines, the company said. Humber will be E.ON's fifth offshore wind farm in the UK.
Construction is expected to start within two years and provide around 1,000 jobs. The farm will create 30 permanent posts.
The Humber Gateway scheme is the first offshore farm to gain planning consent since December 2008. Chris Huhne, the Secretary of State for Energy and Climate Change, said: "A new wind farm off the Humberside coast will be a further jobs and investment boost for the region."
