Independent Power Transmission Operator S.A. (IPTO), the Transmission System Operator (TSO) for the Hellenic Electricity Transmission System has moved closer the electrical interconnection of Folegandros, Milos and Serifos with Santorini and Lavrio. The tender for the cable section of the project, which aims to fully integrate the Cyclades into the continental high voltage system up to 2024, has awarded to Hellenic Cables Group and Prysmian Group as the contractors.

"The cables that, starting immediately, are going to be manufactured in the contractors' factories, will connect the largest islands of the southwestern Cyclades with Attica, creating a strong power supply loop from the High Voltage System. We are confident that the contracting companies with their proven experience and know-how in demanding subsea interconnections, will carry out this important energy project with technical excellence", said the Chairman and CEO Manos Manousakis.

The whole project comprises of two submarine power links: the first will connect Lavrio, a city near Athens on mainland Greece, with the island of Milos, passing through Serifos and the second link, awarded to Prysmian, will connect Milos to Santorini passing through Folegandros.

Prysmian Group will be responsible for the design, supply, installation, and commissioning of a turnkey HVAC (High Voltage Alternating Current) 150 kV three-core cable with XLPE insulation, along a submarine route of more than 100 km and a land route of approximately 10 km. Submarine and land cables will be produced in Prysmian’s plants while offshore installation activities will be performed by one of Prysmian Group’s cable laying vessels. Delivery and commissioning of the cables are scheduled for 2025. Its contract scope is valued at €150 million.

“With the trust IPTO again places in us with this contract, the Group confirms its leadership in submarine cable interconnection in the Mediterranean area, also proving the validity of Prysmian's HVAC cable technologies. The submarine cable system will increase and ensure a robust, reliable, and sustainable power transmission system for the Cyclades islands,” said Hakan Ozmen, EVP Projects BU, Prysmian Group.

Prysmian has been active in the development of submarine interconnection projects across the entire Mediterranean deep water region, such as Italy-Greece, Sardinia-Italian Peninsula (SA.PE.I.), two interconnections between Spain and Morocco, two projects in Spain’s Balearic islands, Capri-Torre Annunziata and Capri-Sorrento in Italy, and the Dardanelles link in Turkey.
