Nexans secures massive contract for offshore wind grid projects

NorthWind partner Nexans, who is a global leader in the cable industry, has been awarded a monumental contract worth an initial €1.7 billion (NOK 19.7 billion) by TenneT, the Transmission System Operator (TSO) for the Netherlands and a significant part of Germany. The contract mandates Nexans to carry out three high voltage direct current projects for offshore wind farms, as part of Europe’s energy transition efforts.

The projects will connect the future offshore wind farms BalWin 3, LanWin 4, and LanWin 2 in the German North Sea to the mainland. In addition to the initial value, the contract includes major subcontracted works that will be added once project-specific call-offs are signed.

Nexans will oversee the full Engineering, Procurement, Construction, and Installation (EPCI) of more than 2,160 km of subsea and land cables. This undertaking comes on the back of Nexans’ successful development and testing of the first 525 kV DC cable in 2022. This breakthrough technology, designed to facilitate the energy transition, will be implemented in these projects.

The cable technology will significantly increase transmission capacity, delivering a total of 6 GW of energy from the North Sea to Germany. The subsea cables for these projects will be manufactured at Nexans’ flagship factory in Halden, Norway.

This agreement follows Nexans’ completion of the DolWin 6 project and the award of the BorWin 6 project last year, reinforcing its long-standing partnership with TenneT. “Nexans is proud to be involved in the ground-breaking developments and delighted to be trusted by TenneT,” says Vincent Dessale, COO and Senior Executive Vice President of Nexans. He emphasises the crucial role of long-term partnerships between suppliers and transmission system operators in enhancing the security of Europe’s energy supply.

The projects are scheduled to be operational between 2029 and 2031.
