Offshore wind farm

London Array

Located 20km off the north Kent coast in the Outer Thames Estuary, London Array has an installed capacity of 630 megawatts and generates enough clean electricity to power around 584,000 UK homes, while displacing around 900,000 tonnes of CO2 a year. The 175 wind turbines each have a rotor diameter of 120 metres and a capacity of 3.6 megawatts each. The wind farm is maintained and operated from the Port of Ramsgate.

London Array was formally inaugurated by then UK Prime Minister, David Cameron on 4 July 2013 and until September 2018, London Array was the largest offshore wind farm in the world.

Community fund

The wind turbines might be 20km out to sea, but London Array still has an effect on the onshore communities in the Cleve Hill and Ramsgate areas.

During construction we established a £300,000 community fund pot to support a variety of groups and businesses local to the project. Since becoming operational, this fund provides £50,000 per annum to support individuals, groups and businesses in North Kent.
