Project Overview
On April 3, 2022, Hellenic Cables, a business of Cenergy Holdings, announced the Hellenic Cables HEDNO submarine cable project. Under this turnkey contract, the company will supply about 19 km of submarine cable to support several new power interconnections across Greece.
The agreement comes from HEDNO, the regulated electricity distributor for the entire country. In addition, the contract covers cable accessories, installation, and all works needed to connect the submarine links to HEDNO’s onshore network, so the scope runs from factory to grid.
Turnkey Scope and Fulgor’s Role
Beyond supplying cable, the project also requires complete execution of the connection works. This includes installing joints, terminations, and related accessories, as well as completing the interface with HEDNO’s land network.
HEDNO signed the contract with Fulgor, a 100% subsidiary of Hellenic Cables. Through this structure, Hellenic Cables and Fulgor manage design, manufacturing, installation, and commissioning as a single integrated team, which in turn simplifies coordination and accountability.
Manufacturing in Corinth and Project Timeline
Hellenic Cables will manufacture all submarine cables at its Corinth, Greece plant, a core facility for high‑performance power products. From there, the project team will handle logistics, marine installation, and final connection to HEDNO’s distribution grid.
Project plans call for cable production and installation to finish by May 2023. With this timeline, HEDNO can continue its broader program to reinforce island and coastal networks and, consequently, strengthen supply reliability for local communities.
Supporting Greece’s Island Grid Modernization
As Greece’s sole active electricity distributor, HEDNO leads efforts to modernize distribution grids and secure power for the country’s islands. By partnering with Hellenic Cables and Fulgor, HEDNO gains a supplier with deep experience in submarine cable systems and turnkey grid projects.
Alexis Alexiou, CEO of Cenergy Holdings and Hellenic Cables, said the company is pleased to support HEDNO’s development plans. He added that the project will help ensure uninterrupted and reliable power for Greek islands and, moreover, reaffirm Hellenic Cables’ role in Greece’s energy transition.
