The company stated that all the 116 turbines are online and feed the renewable energy into the grid.

Power being generated from the wind farm will be sufficient to be supplied to 350,000 UK households, per year, which is about half of the homes in Sussex.

Rampion Offshore Wind Farm project director Matthew Swanwick 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.”

The wind farm, which is located about 13km off the Sussex coast, is owned by E.ON, Canadian energy infrastructure company Enbridge and a consortium that includes Green Investment Group, Macquarie European Infrastructure Fund 5 and the Universities Superannuation Scheme.

The offshore wind farm will generate 1,400GWh of clean electricity per annum which can meet the power consumption needs of 350,000 households while offsetting 600,000 tonnes of carbon emissions per annum.

The electricity produced by the wind turbines of the Rampion offshore wind farm will be transported to an offshore 33kV substation through array cables of a total of 140km that are buried underneath the seabed.

E.ON said that further work on the offshore wind farm will be completed in the coming months.

Swanwick said: “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.”
