As well as the 50% stake, Centrica will take the entire output of the 72MW development, which will produce enough electricity to power the homes of 46,000 British Gas customers.
The agreement with renewable energy firm Airtricity, which developed the 36-turbine site, makes Braes the third operational wind farm in Centrica’s expanding renewable portfolio. The company expects to become one of the largest investors in offshore wind farms.
Jake Ulrich, managing director of Centrica Energy, said: This is another milestone on the journey to supply our British Gas customers with clean and renewable electricity in the years ahead and it will also help to secure the UK’s future energy needs.
Centrica already owns the 26MW Glens of Foudland site in Aberdeenshire and is a 50% partner in the 90MW Barrow Offshore Wind development off the coast of Cumbria.
