Siemens will maintain the power lines and transmission systems linking two TenneT wind farms, HelWin1 northwest of Helgoland and BorWin2 near the island of Borkum, to the mainland. The lines are between 85 and 125 kilometers long and can transport wind-generated power for two million German households. “By moving into the German market for servicing and maintaining offshore-to-mainland connections, we’re expanding our portfolio,” Dehen said. In addition, Siemens will establish a new dedicated service center on the coast of Lower Saxony. The company also plans to expand its European center of wind power competence in Hamburg.
Construction of the Dan Tysk wind farm, which will be located about 50 kilometers west of the island of Sylt, will begin in 2013 and is scheduled for completion by the spring of 2014. Siemens is contributing wind turbines, each with a capacity of 3.6 megawatts and a rotor diameter of 120 meters, as well as providing maintenance services.
