The financial contract for the Dudgeon Offshore Wind Farm in Norfolk has been confirmed.
DECC awarded an Investment Contract last year but the project needed to be confirmed by the Low Carbon Contracts Company (LCCC).
The wind farm will have 402MW of capacity – enough to power around 410,000 homes.
Energy companies Statoil and Statkraft are working together on the development of the wind farm.
Halfdan Brustad, Statoil’s Vice President and Chairman of the Dudgeon Board of Directors said: “Important elements and decisions to undertake the project, such as financial commitment, consents, timetable and key contracts, have been fulfilled.
“Onshore construction has just started but will pick up considerably throughout this year, preparing for the offshore installation campaigns in 2016 and 2017.”
