Hellenic Cables has been awarded a contract from TenneT for the turnkey delivery of approximately 36 km of HVAC offshore grid connection cables for offshore wind farms to be developed in zones (N-3.7 and N-3.8) in Germany.

A press release said that the project, being done in partnership with the Jan De Nul Group, is for the cabling that will connect the wind farms to the DolWin kappa converter station, from where HVDC cables transfer the produced energy to shore. Hellenic Cables will be responsible for designing, manufacturing, supplying, terminating, and testing of three 155kV HVAC grid connection cables and associated accessories.

Manufacturing is planned for 2025 in Hellenic Cables’ submarine cable plant in Corinth, Greece, and delivery is expected in Q3 2025. The Jan De Nul Group will handle the cable transportation, laying and protection works. A single cable will be installed between zone N-3.7 and the DolWin kappa converter, covering a length of 16.5 km. The N-3.8 zone will connect to the converter station by two cables, each about 10 km long.

Hellenic Cables is part of Cenergy Holdings, which itself is a subsidiary of Viohalco SA, a Belgian-based holding company that specializes in manufacturing aluminum, copper, cables, steel and steel pipes.
