DanTysk offshore wind project has started supplying electricity to the German power grid for the first time.
Vattenfall constructed the wind project in a joint venture with and Stadtwerke München (SWM), which owns a 49% stake in it.
Located 70km west to the island of Sylt in the North Sea, the farm has an annual power generation capacity of 1.3TWh, which is enough to meet electricity requirements of 400,000 German homes.
It is equipped with 80 Siemens wind turbines in the 3.6MW class, which all come with maximum rotor tip height of 150m above sea level.
Installation for the turbines began in April of this year.
Commissioning for the turbines at the farm will be done one at a time, and is likely to be concluded by the beginning of 2015.
Vattenfall’s surveillance centre in Esbjerg, Denmark, will monitor the turbines for the wind project.
Vattenfall CEO Magnus Hall said: "Renewables will be Vattenfall’s core business.
"Today, it is cheaper to construct onshore wind farms but costs for building offshore wind farms have fallen considerably."
The Swedish power firm plans to invest Skr11bn($1.4bn) in wind projects over the next four years.
