Besides BalWin3 and LanWin4, Nexans also secured work on the LanWin2 grid connection in the German North Sea. BalWin3 and LanWin4 will connect to the onshore grid in Wilhelmshaven and LanWin2 near Heide.
Under the framework agreements, the French cable maker will be responsible for the full Engineering, Procurement, Construction and Installation (EPCI), including civil works, of over 2,160 kilometres of subsea and land cables.
The initial value of Nexans’s agreements for the three projects signed last year is EUR 1.7 billion, with major subcontracted works to be added once the project-specific call-offs are signed , the company said in May 2023.
According to TenneT, the signing of the call-off contracts for BalWin3 and LanWin4 supports the offshore expansion goals for 2031, providing infrastructure for 4 GW of increased transmission capacity.
For Nexans, the three offshore wind grid connection projects are the first in which the Group is deploying its 525 kV offshore cable technology specifically designed to support the energy transition, the company said.
The subsea cables will be manufactured at Nexans’s factory in Halden, Norway.
The 2 GW HVDC offshore platforms for the grid connections will be built by the Siemens Energy-Dragados Offshore consortium , which also signed a framework agreement with TenneT last year.
