Cenergy Holdings announces that Hellenic Cables, its cable division, through its wholly-owned subsidiary Fulgor S.A., has been selected as the contractor under the framework agreement with the Independent Power Transmission Operator (ADMIE) for Lot A of the electrical interconnections of the Dodecanese and the North Aegean islands, with a total value of approximately 1.15 billion euros.
Under the agreement, Hellenic Cables will undertake the Engineering, Procurement, Construction, and Installation (EPCI) of four (4) interconnections, specifically Thrace–Lemnos, Kos–Rhodes, Lesbos–Lemnos, and Lesbos–Chios. Their total length amounts to approximately 694 km of 150-kV alternating current (AC) submarine cables and 227 km of 150-kV alternating current (AC) underground cables. Production is expected to begin in 2027, while the projects are scheduled for completion by 2031.
This contract is part of ADMIE’s strategic program to strengthen the interconnection of the Greek islands with the national electricity transmission system and to support the country’s energy infrastructure.
The electrical interconnection of the Dodecanese and the North Aegean islands is critical to the stability of the Greek power system, as it eliminates the electrical isolation of the island grids by integrating them into the mainland grid. This interconnection significantly enhances reliability, security of supply, and the system’s ability to balance energy demand and production from renewable sources throughout the country.
The submarine cables will be manufactured at Hellenic Cables’ state-of-the-art production facilities in Corinth, while the underground cables will be produced at the company’s plant in Thebes. Following recent investments, both facilities are now operating at increased production capacity, further strengthening Hellenic Cables’ ability to support large-scale power interconnection projects.
The signing of the framework agreement is subject to the completion of the required regulatory procedures and approvals, and its implementation is contingent upon the client issuing a corresponding work order.
Alexis Alexiou, CEO of Cenergy Holdings, stated: “This project demonstrates ADMIE’s confidence in Hellenic Cables’ ability to implement complex and strategically important electricity transmission projects. The interconnection of the Greek islands is a key pillar of the country’s energy infrastructure and strengthens the grid’s energy security and resilience. “We are proud to contribute to this effort by leveraging our advanced production capabilities and our proven expertise in project implementation.”
