Wpd is planning to start building the Suurhiekka project, which is located in the Gulf of Bothnia, in 2014. It will consist of 80 turbines and will reportedly have a combined capacity of 600MW.
The authorisation, which includes environmental considerations, was granted by the Regional State Administrative agency of North Finland. However, the project still requires technical approval before construction can commence.
Wpd has been working on the project since 2007, while the application was filed in 2009.
Last year, the Swedish subsidiary of wpd was given the green light to build the Storgrundet offshore wind development. The project will consist of up to 53 turbines and a capacity of 265MW.
