UK trade body RenewableUK has announced that Triton Knoll Offshore Wind Farm, to be built off the east coast of England, has received final consent from the Department of Energy & Climate Change (DECC).

The proposed offshore wind power facility, which will have 288 turbines, is expected to have an installed capacity of about 1.2GW.

The clean electricity generated at the wind power project will be enough to power approximately 900,000 homes annually.

Triton Knoll project, which represents the last of the major Round 2 offshore wind projects to be approved, is anticipated to create 800 jobs, while providing £3.6bn in investments.

Meanwhile, DECC has also approved £400m in investment for the Pen y Cymoedd onshore wind project, to be built in South Wales.

Construction of the Pen y Cymoedd wind farm, which will deploy 76 turbines, will begin in 2014 with power being generated first for the National Grid in late 2016.

Commenting on the developments, DECC State Secretary Edward Davey said that the two projects are expected to attract billions in investment into the UK, create hundreds of skilled green jobs in Lincolnshire, Norfolk and in the county boroughs of Neath Port Talbot and Rhondda Cynon Taf, while providing homes with clean energy.

RenewableUK Offshore Renewables director Nick Medic said, "The planning consent today keeps the country firmly at the forefront of offshore wind development and will help secure up to 20% of electricity from offshore wind per year by 2020.

"We now need to have the policy framework in place to Britain secures the rewards of this new energy revolution by maximizing employment and creating opportunities for UK businesses."
