Hellenic Cables undertakes the implementation of the Lavrio-Serifos and Serifos-Milos offshore electrical interconnections

Athens, 23 November 2022

Hellenic Cables, the cables segment of Cenergy Holdings, was commissioned by IPTO to carry out the Lavrio-Serifos and Serifos-Milos electrical interconnections as part of the 4th phase of the interconnection of Cyclades with the continental Electricity Transmission System, with a total length of 170 km.

More specifically, the “turnkey” project includes the design, manufacturing, and supply of the 150 kV onshore and offshore high voltage cables as well as their accessories, the installation, laying, and protection of the onshore and offshore cables, jointing and terminations, testing and commissioning. The relevant contract is expected to be signed within 2022 following the completion of the legal pre-contractual procedures.

The project that will integrate Milos and Serifos into the continental Electricity Transmission System is part of the fourth and final phase of the Cyclades’ interconnection and will be completed in 2024.

Upon operation, the new interconnection will significantly upgrade the quality of electricity in further sevendirectly and indirectly interconnected islands of the Cyclades (Folegandros, Milos, Serifos, Ios, Kimolos, Sifnos, and Kythnos) throughout the year while allowing the gradual withdrawal of the polluting and aging power plants that are still operating in Milos and Serifos.

The implementation of the project, including the installation of the cables, is expected to be completed within 28 months from the signing of the relevant contract. The cables will be manufactured at Hellenic Cables’ state-of-the-art plant in Corinth.

Mr. Alexis Alexiou, CEO of Cenergy Holdings and Hellenic Cables, stated: “We are proud to contribute with our products and services to the energy integration of the Cyclades in the continental system, supporting the island economy, energy security and reducing emissions of carbon emissions (CO2) of the country.”
