Do you support the continued expansion of large-scale offshore wind power grid infrastructure?
Nexans has officially moved to the industrial-scale manufacturing phase for subsea cables at its facility in Halden, Norway. The cables will facilitate the 2GW LanWin2 grid connection project, linking offshore wind power in the German North Sea to the Heide region.
Why it matters
This partnership aims to secure essential supply chain capacity and accelerate the development of transmission infrastructure for wind power. It ensures long-term planning certainty for TenneT’s broader 2GW offshore grid connection program.
The project utilizes 525 kV HVDC XLPE cable technology to transport 2GW of power. This infrastructure is a critical element of the TenneT offshore grid connection programme.
The players
Nexans
Nexans is a global leader in the cable industry that provides advanced infrastructure solutions for energy and data transmission.
TenneT
TenneT is a leading European transmission system operator with activities in the Netherlands and Germany.
The details
Manufacturing follows the successful technical qualification of the 525 kV HVDC XLPE subsea cable system. The cables will connect the German North Sea to the transmission network at the HeideHub, supporting the transition toward large-scale renewable energy integration.
Timeline
The companies established a strategic frame agreement in 2023.
Cable installation activities for the BalWin3 project are planned for 2027.
The LanWin2 project is scheduled to be commissioned in 2031.
Market Landscape
This transition to industrial-scale production signals a shift toward standardized high-voltage components in the European offshore energy sector. It positions Nexans as a primary supplier within the highly competitive market for grid connection technology.
The acceleration of transmission infrastructure projects helps stabilize the long-term energy supply for the regional power grid. Customers can expect progress toward grid integration as these large-scale offshore wind projects move toward completion.
The takeaway
The move to industrial production highlights the critical role of specialized cable technology in scaling renewable energy connectivity. Standardizing these components is essential to hitting the ambitious commissioning timelines required for future offshore wind expansion.
What happens next
Cable installation for the BalWin3 project is planned for 2027, followed by the expected commissioning of the LanWin2 project in 2031.
