All 116 turbines at Rampion offshore windfarm are now able to generate electricity as the development reaches its maximum generation capacity of 400MW, Eon has confirmed.
The project, located 13 kilometres off the coast of Sussex, is expected to be fully operational later this year.
It will provide enough electricity to supply almost 347,000 homes per annum, the equivalent to around half the homes in Sussex.
Matthew Swanwick, project director, said: “We’re delighted to have now reached the point where all of the wind turbines are up and running and contributing yet more clean power, adding to the UK’s growing renewables fleet and its ability to help meet the UK’s energy needs.
“We still have a number of activities to complete, for example at the onshore and offshore substations and landfall, so people will continue to still see ongoing activities offshore and onshore over the coming months. Full reinstatement of the onshore cable route back to its former condition is another top priority for us this year.”
The windfarm is being built by Eon, which has a 50.1 per cent share in the project; a consortium comprising of the Green Investment Group, Macquarie European Infrastructure Fund 5 and the Universities Superannuation Scheme (25 per cent); and Canadian energy infrastructure firm Enbridge (24.9 per cent).
Eon announced it would invest around £1.3 billion in the project when it was given the go ahead in May 2015.
Work to prepare the seabed for turbine foundations began in autumn 2016 and turbine installation kicked off in March last year. It was finished ahead of schedule in September 2017.
