Description
50Hertz awarded NKT a major multi-project EPCI framework order covering several 525 kV HVDC cable systems, including the LanWin 6 offshore grid connection in the German North Sea. Under this agreement, NKT will design, manufacture, supply and install the LanWin 6 525 kV XLPE HVDC export cable system, providing approximately 900 km of core cables (including DC conductors and metallic return) to connect 2 GW of offshore wind capacity from the N-12.x area to the onshore grid hub near Pöschendorf in Schleswig-Holstein. The work spans subsea and land sections and forms part of 50Hertz’s long-term grid expansion programme targeting commissioning in the mid‑2030s. The total value of NKT’s five-project package is about EUR 3.5 billion, but the share attributable specifically to LanWin 6 is not disclosed.
