DanTysk offshore wind farm in the German North Sea was officially. Siemens has supplied, installed and commissioned 80 wind turbines for the 288-MW project, each designed to generate 3.6 MW of power and equipped with a 120-me rotor. Now Siemens wind turbines with a total capacity of over 1 GW feed offshore wind power into Germany’s power grid.
Owner and operator of DanTysk wind park is a consortium comprising the Swedish power company Vattenfall and Stadtwerke München, Munich’s municipal utility. The wind power plant can generate up to 1.3 GWh of electricity every year – equivalent to the total annual consumption of about 400,000 German households.
DanTysk offshore wind farm is located approximately 70 km offshore west of the German island of Sylt. In waters measuring between 21 and 32 meters deep, foundations anchored in the seabed provide the base on which the wind turbines were erected. The wind turbines are not the only thing Siemens is providing DanTysk: the German technology group is taking charge of preventive and corrective maintenance to the wind turbines within the scope of a five-year service agreement, and also supplied the turnkey grid connection for the wind power plant, called SylWin1. This direct-current (DC) offshore link, run by the transmission grid operator TenneT, comprises the connecting systems that connect the offshore wind power plant to the German electricity grid. SylWin1 consists of an offshore converter station at sea, and a receiver station on land, 160 kilometers of undersea cable and further 45 kilometers of underground cable on shore. Overall, three offshore wind power plants will be connected to the grid via this offshore link.
