Hellenic Cables-Inauguration of Skiathos-Euboea electric interconnection

The project is already in full operation

Athens, 30 August 2022

The official inauguration of Skiathos- Euboea electrical interconnection took place with great success, on Monday August 29, 2022, at the state-of-the-art Skiathos High Voltage Substation. This is another major energy project where the submarine cable was constructed and installed by Hellenic Cables, a subsidiary of Cenergy Holdings.

The electrical interconnection between Skiathos and Euboea is in full operation since July 11, already set to successfully meet Skiathos’ increased demands during the current tourist season, as well as those of all Northern Sporades Islands. It is a project of great technical complexity, which involves the design and delivery of approximately 29 km in total of 150 kV submarine cable, 150kV submarine cables, the underwater submarine cable at a depth of about 200 meters, the installation of land cables, the protection of the submarine cable on the seabed along its entire length as well as the protection of the underground cables on land, the connection of the submarine to the land cables at the mooring areas and their terminals connecting the underwater cable system to the 150 kV national Transmission System at Mandoudi in Euboea. 

At his speech, Mr. Manos Manousakis, President and CEO of IPTO, stated: “We are very pleased as our commitment to electrify the Skiathos-Euboea interconnection in summer 2022 became a reality. We achieved this demanding goal thanks to the dedication of our executives and partners and the support of the local community that “embraced” the project from day one. Today, Skiathos and Northern Sporades are energy safe and enjoy reliable and quality electricity from the mainland. IPTO continues its EUR 5 billion investment program, while completing this important milestone for the National Transmission System, thus contributing to the country’s energy upgrade heading towards 2030.”

“I would like to thank the whole team of Hellenic Cables and our partners who worked hard on this project and managed to complete it successfully. Once again we demonstrate our reliability as providers of high technology cable solutions and our ability to effectively complete demanding electrical interconnections such as Skiathos. We also thank IPTO for entrusting us a significant role in the deployment of the energy shield of Greece”, said Mr. Alexis Alexiou, CEO of Hellenic Cables and Cenergy Holdings.
