Nexans starts cable output for German offshore grid
Manufacturing has begun in Norway for high-voltage direct current cables destined for TenneT's LanWin2 grid connection.
Key points
- Nexans started industrial-scale production of 525kV HVDC XLPE subsea cables at its Halden facility in Norway.
- The infrastructure will link German North Sea wind generation to the national transmission grid.
- Commissioning of the LanWin2 link is scheduled for 2031, with related work also slated for the BalWin3 project.
What happened
Power Technology reported that Nexans and TenneT have initiated manufacturing operations for high-voltage underwater cables supporting the LanWin2 offshore grid project. Fabrication is underway at the industrial facility located in Halden, Norway.
This undertaking represents the initial commercial-scale deployment of the 525kV high-voltage direct current XLPE subsea cable system by the manufacturer. The delivery phase follows the successful conclusion of testing and engineering phases under a framework agreement established between the companies in 2023.
Why it matters
The infrastructure project is designed to connect wind power facilities situated in the German North Sea directly to the primary mainland transmission grid. The technology enables the efficient transfer of substantial quantities of renewable electricity across extended maritime routes.
Pascal Radue, executive vice president for PWR-Transmission at Nexans, noted in the source reporting that the milestone reflects the strength of the firm's manufacturing capacity and its backing of European energy infrastructure. Matthias Mensing, head of investment projects management and support at TenneT, described the development as a significant step for the broader two-gigawatt initiative.
What comes next
Full delivery schedules remain active for related regional projects. Installation work for the BalWin3 initiative is planned for 2027, while commercial operation for the LanWin2 connection is targeted for completion by 2031. Both developments remain on schedule as part of broader efforts to expand offshore transmission networks.

Context from CEII
Grids decide whether generation becomes power that homes and businesses can rely on. Generation mix, transmission and distribution losses, and tariffs together shape reliability and the case for investment.
