Following the grid connections for the offshore wind farm clusters BorWin2 and HelWin1, Siemens Energy will also install a turnkey grid connection in the North Sea for the SylWin cluster. Purchaser is the Dutch-German transmission grid operator TenneT. In a consortium with the Italian cable manufacturer Prysmian Powerlink, Siemens will connect DanTysk, located west of the island of Sylt as the first wind farm to be connected via the SylWin collective connection. Equipped with 80 Siemens wind turbines, DanTysk will have a total capacity of 288 megawatts (MW) and supply up to 500,000 German households with clean electricity.
The wind farm will be connected to the mainland grid via a high-voltage direct-current (HVDC) transmission link using subsea and underground cable. Including its internal efforts, TenneT estimated the total investment volume at nearly one billion euros. More than a quarter of this sum has been awarded to Prysmian for supply of the cables. The Siemens share is significantly higher. The grid connection is scheduled to be ready for operation by early 2014.
