The German-Dutch transmission grid operator TenneT has received ownership of SylWin1, the most powerful offshore grid connection to date. The offshore platform of the SylWin1 grid connection is located around 70 km west of the German Island of Sylt, of which the project was named.

Wind power is transmitted through a subsea and underground cable, over 200 km to the land-based station Buttel. This grid connection can transport up to 864 MW of renewable energy, enough to supply nearly a million German households.

Jan Mrosik, CEO of the Siemens Energy Management Division said: "This year we have completed the world's first three offshore grid connections with efficient direct-current technology - SylWin1, BorWin2 and HelWin 1. We also intend to put the fourth project HelWin2 into commercial operation as planned in the coming weeks."

Three offshore wind farms (DanTysk, Butendiek and Sandbank), each with a capacity of 288 MW are connected to SylWin1. DanTysk and Butendiek both have 80 Siemens wind turbines, each rated at 3.6 MW, whereas Sandbank will eventually have 72 wind turbines in the new 4-MW class.
