The UK Government has approved RWE Innogy's plans to construct the 1.2GW Triton Knoll offshore wind farm in England, which has been proposed to be larger than the recently opened London Array.
Located off the Lincolnshire and Norfolk coast, the £3.6bn wind farm will feature 288 turbines and generate enough power for approximately 820,000 homes.
As part of the proposal, RWE is also planning to construct a substation, which will be connected to the offshore wind farm after completion.
Triton Knoll project manager Jacob Hain said the wind farm is a well sited project and securing approval is a milestone.
RenewableUK offshore renewables director Nick Medic said Triton Knoll offshore wind farm is the biggest project approved so far anywhere in the world.
"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 each year by 2020," Medic said.
The UK Government has also approved the construction of Pen y Cymoedd wind farm in South Wales.
After completion, the wind farm will feature 76 turbines and generate enough electricity for around 140,000 homes.
Construction on the wind farm is expected to start in 2014, with first power being generated for the National Grid in late-2016.
Vattenfall said it will invest £400m in the wind farm and also spend £1.8m a year into community funds for the 25-year life of the wind farm.
UK Secretary of State for Energy Edward Davey said offshore and onshore wind is an important contributor to the country's energy mix.
"These two projects will attract billions in investment into the UK, support 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," Davey said. "We have provided certainty early to onshore and offshore wind investors and now see significant investment decisions being made that will benefit the UK's economy for years to come."
Upon completion, both wind farms will generate enough power for approximately one million homes and bring in more than £4bn of investment for the country.
