Nexans to Deliver Subsea and Land Cables for TenneT
Nexans won a German turnkey contract from TenneT to manufacture and install direct current (DC) subsea and land cables for the BorWin6 grid link. The 235 km, 320 kV DC connection will carry up to 980 MW from the BorWin offshore cluster to the German onshore grid.
Germany plans to reach 30 GW of offshore wind capacity by 2030, so BorWin6 plays an important role in bringing that clean power ashore and supporting national climate targets.
Scope of the Nexans BorWin6 Subsea Cable Project
To electrify BorWin6, Nexans will manufacture, install, and protect 320 kV DC XLPE single‑core cables for TenneT. The subsea section will total 2 x 190 km from Nexans’ flagship plant in Halden, Norway. In addition, the land section will total 2 x 46 km from its Charleroi, Belgium facility.
The award includes a full Engineering, Procurement, Construction and Installation (EPCI) scope. Therefore, TenneT works with one integrated partner from design through final installation.
Supporting Germany’s Offshore Wind Expansion
BorWin6 is TenneT’s final 320 kV HVDC project that connects the remaining almost 1 GW from the BorWin cluster in the German North Sea to the onshore network. The project appears in Germany’s official Area Development Plan and should start operation in 2027.
By adding this HVDC link, Germany can move more offshore wind power into its grid. As a result, the country improves security of supply and accelerates its energy transition.
Nexans Focuses on Electrification and Innovation
Nexans notes that the BorWin6 subsea cable project reflects its commitment to innovation, sustainability, and electrification. The company continues to invest in high‑voltage DC cable technology and turnkey project capabilities to help utilities connect large‑scale renewables.
With BorWin6, Nexans further reinforces its position as a leading supplier of HVDC subsea and land cable systems for Europe’s offshore wind and interconnector projects.
