TenneT Selects NKT for High-Voltage Cable Systems in Germany
The Dutch-German transmission system operator (TSO) TenneT has chosen Danish subsea cable and services firm NKT to provide onshore and offshore high-voltage cable systems for two projects in Germany as part of its 2 GW grid infrastructure program.
Under the existing multi-year framework agreement with TenneT, NKT will supply 525 kV XLPE high-voltage direct current (HVDC) onshore and offshore power cable systems for the LanWin7 and NordOstLink projects.
The contracts, expected to be executed in 2026-27, have a combined value of approximately $1.03 billion, covering cable design, engineering, production, and on- and offshore installation.
Project Details
The LanWin7 system is part of the offshore grid connection systems planned to link to the multi-terminal hub in Pöschendorf, Schleswig-Holstein. This NordHub will combine multiple DC and AC connections, facilitating the efficient transport of wind power from the North Sea to the onshore grid.
The NordOstLink project involves laying additional cables to enhance grid capacity and flexibility.
Both projects are set to be commissioned in 2033-34.
NKT’s Response
Claes Westerlind, President and CEO at NKT, expressed excitement about being selected as a key partner for TenneT’s 2GW Program. He highlighted NKT’s strong partnership with TenneT and its leading position in the high-voltage DC power cable market.
Westerlind stated, “We look forward to applying our advanced power cable technology to these two additional projects in Germany, which will support the energy transition in Europe by enabling the efficient transport of wind power from the North Sea to the onshore grid.”
With the LanWin7 and NordOstLink projects, NKT has now secured a total of five projects under the framework agreement with TenneT, which is set to run until 2028 with a possible extension until 2031.
Overall, this partnership between TenneT and NKT signifies a significant step towards enhancing the grid infrastructure in Germany and facilitating the transition to renewable energy sources.
