On June 2, 2011, Norddeutsche Seekabelwerke GmbH (NSW) has been awarded a major order by TenneT TSO GmbH (TenneT), a German-based transmission network operator, for the supply and installation of 2 x 13 kilometers of 155 kV AC submarine transmission cables.
The cable will provide the network connection of the offshore wind park transformer platform MEG 1 to the converter station DolWin alpha, which is operated by TenneT. DolWin alpha is located in approximately 75 km distance to the German Coast in the North Sea. The offshore converter station DolWin alpha is transforming the wind energy generated offshore from AC into DC current which is being transported a total of 165 km to the converter station Dörpen West. This 800 MW high-voltage direct-current transmission is being realized in TenneT’s project DolWin1.
