German HVDC connection commissioned
Prysmian Group has successfully commissioned the High Voltage Direct Current (HVDC) offshore grid connection project, HelWin2, off the North Sea coast of Germany in a contract with the Dutch-German transmission system operator TenneT.
Prysmian secured the project in July 2011 as one of several contracts awarded to consortia between the Group and Siemens Energy for the grid connection of offshore windfarms to the mainland.
“We are proud to deliver on time such a highly strategic project for the German power grid” said Massimo Battaini, senior vice president, Energy Project at Prysmian Group. “The Prysmian/Siemens consortium is the first to complete such a German offshore grid connection within the agreed timeframe.”
HelWin2 now links the offshore wind park, Amrumbank West, with a 690 MW cable connection operating at the highest commercially available voltage of ± 320 kV DC, along a total route of 130 km (85 km submarine and 45 km land) to the mainland Germany land converter station in Büttel, north-west of Hamburg and is ready to start commercial operations.
