Siemens has handed over SylWin1, an 864MW HVDC offshore wind grid hub in the German North Sea, to transmission operator TenneT.
The SylWin Alpha platform of the hub is located roughly 70km west of the island of Sylt. It will link the offshore wind farms DanTysk, Butendiek and Sandbank (all 288MW) to shore.
Siemens already has more than 100 wind turbines linked to the grid connection. It is adding to that number each day. The wind farms have transmitted a capacity of 350MW under optimal wind conditions through the SylWin1 link.
Power from the offshore wind farms is transmitted by means of more than 200km of subsea and underground wire to an onshore substation at Buttel in northern Germany.
Siemens has reported that it completed three offshore grid connections, first in the world, with direct current technology this year.
Besides the three connections SylWin1, BorWin2 and HelWin1, the company also “plans to put the fourth project HelWin2 into commercial operation as planned in the coming weeks” according to the chief executive of the energy management division of Siemens Jan Mrosik.
“We will be completing further offshore grid connections by the end of the year. In all we will have implemented a capacity of more than 5000 MW, or more than two-thirds of the offshore expansion goal set by the German government,” TenneT board member Lex Hartman added.
