Commissioning of the HVDC HelWin1 link, including the onshore converter station at Büttel and the offshore HelWin Alpha platform, was completed in January 2015. This concluded testing and commissioning of the 576 MW, ±250 kV system and allowed the project to be handed over to its owner TenneT in February 2015 for operational service transmitting offshore wind power from the German Bight to the mainland grid.
