Siemens has handed over the first North Sea grid connection, BorWin2, to its customer TenneT. The German-Dutch transmission grid operator has accepted the project following successful completion of test runs by Siemens.
The 800MW grid connection is therefore now in commercial operation. The offshore platform of the BorWin2 grid connection is located around 100 kilometers off the German coast, northwest of the island of Borkum. The BorWin2 offshore platform is 51 meters wide, 72 meters long, 25 meters high and, with its baseframe, weighs around 16,000 metric tons. Siemens installed the platform at this 39-meter-deep North Sea location back in April 2014. The Global Tech 1 wind farm, with its 80 wind turbines, is linked to BorWin2. Fifty per cent of the grid connection capacity of BorWin2 is available for connection of a second wind farm. Siemens is implementing five North Sea grid connection projects for TenneT: HelWin1 (576 MW) and HelWin2 (690 MW) off of Helgoland, BorWin2 (800 MW) and BorWin3 (900 MW) off of Borkum and SylWin1 (864 MW) off of Sylt.
