Cenergy Holdings announces that Hellenic Cables, its cable division, through its wholly owned subsidiary Fulgor S.A., has signed a turnkey contract with the Independent Power Transmission Operator (IPTO) for the engineering, procurement, construction and installation (EPCI) of the 320kV HVDC power interconnection between Corinth and Kos, with a total value of approximately €1.5 billion.
The project includes approximately 1,260 km of submarine cables and 30 km of underground cables for the Corinth–Kos power interconnection.
The project is expected to begin in the fourth quarter of 2026 and be completed in 2030.
Hellenic Cables, through its wholly owned subsidiary Fulgor S.A., is responsible for delivering the complete project, from one converter station to the other, and will manufacture the HVDC power cables at its facilities in Corinth and Thebes.
The Corinth–Kos interconnection is a project of strategic importance that will connect the Dodecanese islands to the country’s mainland electricity transmission system. With a transmission capacity of 1 GW, the project will help enable the gradual retirement of costly, high-carbon-emitting oil-fired power stations, while significantly strengthening the security and reliability of energy supply.
Alexis Alexiou, CEO of Cenergy Holdings, said: “Signing this landmark contract marks an important step in the development of Greece’s electricity transmission infrastructure. We are particularly pleased to be working with IPTO on the Corinth–Kos interconnection, contributing our expertise in HVDC cable systems and the delivery of complex turnkey projects, with the aim of connecting the Dodecanese islands to the mainland electricity grid. We look forward to delivering this important project safely and reliably.”
