Skiathos-Evia electrical interconnection now operational

The interconnection was implemented by the Administrator as part of a 57 million euro investment

The electrical interconnection of Skiathos with Evia was put into operation on Monday, July 11, which, according to the Independent Power Transmission Operator-IPTO, ensures a stable and reliable electricity supply for the island and all the northern Sporades from the National Electricity Transmission System, in all operational conditions, minimizing the risk of blackout during severe weather or increased demand.

The Skiathos-Evia electrical interconnection was implemented by the Operator as part of an investment of 57 million euros. On the Skiathos side, the interconnection includes a state-of-the-art 150kV Closed Type (GIS) Substation, while the High Voltage cables installed on the island are fully underground with the aim of minimizing environmental and visual nuisance.

A unique feature of this particular project is that the submarine cable is buried throughout its 29 km long subsea route, at depths of up to 300 m, ensuring its protection from external factors. On the Evia side, ADMIE upgraded the existing Mantoudi Substation, while constructing 30 km of new overhead transmission line.
