Nexans secures €1bn LanWin2 project with TenneT for offshore grid

Cable systems and services provider Nexans has signed a €1 billion ($10.3 billion) agreement with TenneT for the LanWin2 project, part of TenneT’s 2GW offshore grid connection programme in the German North Sea.

The LanWin2 project includes the engineering, procurement, construction, and installation (EPCI) of 525 kV high-voltage direct current (HVDC) onshore and offshore export cable systems. Spanning 250 km, the system will transmit 2GW of renewable wind energy and is expected to be operational by 2030.

Electricity generated from wind farms will flow through offshore and onshore converters connected via a high-performance cable system. It will be transformed from three-phase current to direct current offshore and transported to the mainland, where it will be converted back to three-phase current for integration into the grid.

LanWin2 and its counterpart, LanWin3, will source electricity from the HeideHub multiterminal hub, comprising offshore converters in the North Sea and onshore converters in Schleswig-Holstein.
