Contract Details
Description
Nexans is contracted by TenneT under its 2 GW programme to deliver the full offshore and onshore export cable system for the 2 GW BalWin3 HVDC grid connection in the German North Sea. Under a 2023 frame agreement followed by a 2024 project-specific call-off for BalWin3 and LanWin4, Nexans is responsible for engineering, procurement, construction and installation (EPCI) of the 525 kV HVDC XLPE subsea and land cable systems linking offshore wind area N-9.2 to the Wilhelmshaven2 grid point. The scope includes detailed design, manufacture and supply of both submarine and onshore export cables, associated accessories and civil works, as well as offshore and nearshore installation. Using its Halden, Norway facility and specialist installation vessels, Nexans will provide approximately 400 km of subsea HVDC export cable and 90 km of onshore HVDC cable for BalWin3, with commissioning targeted for 2031. The contract forms part of a wider 1.7 billion-euro framework covering three German offshore grid connections.
