Connecting Greece’s Cyclades Islands to the mainland’s power

Three PhasesSubstantial Environmental BenefitsBenefiting The Greek EconomyTotal Investment and EU FundingIn total, the project will install over 300 km of submarine cables, with 152.4 km having already been laid. These cables run from the mainland’s power stations to the various islands. The connections are being made in three phases. In phase A, which started in March 2018, the Syros oil-based power station went offline as the island was connected to the Hellenic Electricity Transmission System via the Lavrion GIS substation on the mainland. Today, the electricity needs of Syros, Paros, Antiparos, Naxos, Koufonissi, Schinoussa, Iraklia, Ios, Sikinos, and Foleganros are all covered by the mainland electricity transmission system. During phase B, Paros and Naxos will be connected to the mainland, and Naxos with Mykonos island. Finally, in phase C, a second interconnection between the mainland (Lavrion) and Syros will be made.Get price
