Folegandros island connected to Greek mainland grid via 60-km subsea cable

A 60-km subsea high-voltage cable linking Folegandros to Santorini and Naxos has been energized, integrating the island into Greece's mainland power grid. This reduces reliance on local diesel generation and improves energy security for the Cyclades. The project is part of a broader interconnector program, with further island connections likely.
