The project that will integrate Folegandros, 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. With its operation, 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 it will allow the gradual withdrawal of the polluting and old technology power plants that are still operating in Milos and in Serifos.

The project, with a total budget of 345 million euros, has applied for co-financing of 103.5 million euros from the Recovery and Resilience Fund.
