On 11 July 2022, IPTO (ADMIE) commissioned the new 150 kV closed-type GIS onshore substation on Skiathos as part of the Skiathos–Evia electrical interconnection. The substation, together with the new Mantoudi Evia–Skiathos transmission line and a buried 29 km subsea high-voltage cable, began successfully transmitting the first electrical loads to Skiathos, providing stable and reliable supply from the Greek national transmission system. The project, implemented under a €57 million joint ADMIE–HEDNO investment, is reported as completed with the Skiathos substation in operation.
