The manufacturing of the cables for the Folegandros-Milos-Serifos electrical connection begins

Hellenic Cables and Prysmian are the contractors of the cable section of the project

IPTO brings the construction of the electrical interconnection of Folegandros, Milos and Serifos with Santorini and Lavrio one step closer, after the selection of the final contractors for the project of the design, supply and installation of underground and subsea high-voltage 150 kV AC cables.

More specifically:

  • The Hellenic Cables Group undertakes the cable section of the Lavrio-Serifos and Serifos-Milos interconnection (Section A), with a total length of 170 km and a contract price of EUR 195 million.
  • The Prysmian Group undertakes the cable section of the Milos-Folegandros and Folegandros-Santorini interconnection (Section B), with a total length of 127 km and a contract price of EUR 150 million.

The relevant contracts are expected to be signed within 2022 after the completion of the legal pre-contractual procedures.

The project that will integrate Folegandros, Milos and Serifos into the mainland Electricity Transmission System is part of the fourth and final phase of the interconnection of the Cyclades and will be completed in 2024. When launched, the new interconnection will significantly upgrade the quality of electricity in 7 more directly 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 obsolete power plants that are still operating in Milos and Serifos. 

The project, with a total budget of EUR 345 million, has been included in the co-financing of EUR 103.5 million provided under the Recovery and Resilience Fund.

The Chairman and CEO of IPTO, Mr. Manos Manousakis, said in this regard: “IPTO has made another step closer to the completion of the electrical interconnection of the Cyclades with the mainland system. The cables, whose construction at the factories of the contractors is about to start soon, will connect the largest islands of the southwestern Cyclades with Attica, creating yet another powerful supply loop from the High Voltage System. We are confident that the contracting companies, thanks to their proven experience and know-how in demanding underwater interconnection projects, will carry out this important energy project with technical excellence.”
