Nexans starts offshore wind grid connection cable production in Norway

Nexans, a company focused on electrification, has commenced subsea cable production for the LanWin2 offshore grid connection project at its facility in Halden, Norway. This milestone represents the first industrial-scale manufacturing of Nexans' 525 kV HVDC XLPE subsea cable technology and signifies the beginning of the delivery phase for LanWin2.

The production launch follows the successful qualification of the 525 kV HVDC XLPE cable technology. The LanWin2 project, developed by TenneT, aims to connect offshore wind generation in the German North Sea to the country's transmission grid. This is part of a broader effort to integrate large-scale renewable electricity into Germany's energy system.

This development occurs under a long-term frame agreement established in 2023 between Nexans and TenneT, designed to secure supply chain capacity and accelerate the delivery of critical transmission infrastructure for Europe's energy transition. "Long-term partnerships like this give us the supply-chain capacity and planning certainty we need to deliver the offshore grid infrastructure for Germany's energy transition," stated Matthias Mensing, Head of Investment Projects Management & Support at TenneT.

The LanWin2 project is scheduled for commissioning in 2031. The commencement of production also demonstrates the readiness of Nexans' 525 kV HVDC XLPE technology for other projects under the TenneT frame agreement, including BalWin3, with nearshore installation activities planned for 2027. Both projects are proceeding on schedule, reflecting momentum in TenneT's offshore grid expansion program.
