Nexans wins €1.43 billion contract for Great Sea Interconnector
Nexans has secured a €1.43 billion contract to supply and install subsea cables for the Great Sea Interconnector linking Greece and Cyprus. The project sets records for cable length and depth.
Paris, FRANCE – Nexans, a global leader in cable systems, has been awarded a €1.43 billion contract for the Greece-Cyprus section of the Great Sea Interconnector project. This subsea electricity link is part of a broader initiative to connect the power grids of Greece, Israel, and Cyprus.
The interconnector will feature the world's longest and deepest subsea high-voltage direct current (HVDC) cable system, with a total length of 1,800 kilometers for both poles. The cables will be laid across the Mediterranean Sea floor at depths exceeding 3,000 meters. Nexans' specialized cable-laying vessels, Nexans Aurora and Nexans Skagerrak, will undertake the installation. The connection is designed to transmit up to 2,000 MW of energy, sufficient to power approximately three million European households.
This infrastructure project is expected to enhance regional energy security and end Cyprus's isolation within the European Union's electricity grid. It is also viewed as a significant step towards decarbonization and achieving European Union energy objectives. The subsea cables will be manufactured at Nexans facilities in Halden, Norway, and Futtsu, Japan.
The Great Sea Interconnector has been designated a Project of Common Interest (PCI) by the European Union, which aims to streamline permitting and reduce administrative burdens. Pole One of the interconnector is scheduled for completion in 2028, with Pole Two following in 2029. Nexans has previously undertaken major international cable projects, including a 2 GW framework agreement with TenneT and the Celtic Interconnector linking Ireland and France.
