Under the agreement, Areva will also provide commissioning, testing and maintenance services.

The contract comprises an additional 40 M5000 turbines within the year 2011.

Situated 45km off the northern coast of the island of Borkum, Borkum West II is the biggest wind-energy project in the German North Sea.

It is directly adjacent to Alpha Ventus, Germany’s pilot offshore wind farm where Areva supplied six wind turbines.

Areva said that the operations are scheduled to start at the turn of the year 2012/2013.

Once completed, the turbines will generate a total output of 200MW, enough to provide some 200,000 households with green electricity.
