Greek power grid operator IPTO has begun preparations to launch, later in 2024, tenders to offer contracts for the development of an electrical interconnection linking the Dodecanese islands with the mainland.
These tenders concern the cable sections and two converter stations of the Corinth-Kos interconnection, to serve as the main line linking this group of Greek islands in the Aegean Sea’s southeast with the mainland network.
The link is planned to be developed as a 900-MW High Voltage Direct Current (HVDC) connection, the country’s second, following the Crete-Athens link.
The Dodecanese islands link will replace six independent grids covering the energy needs of these islands. Besides providing a link to the mainland, the Dodecanese islands grid interconnection will also facilitate greater RES penetration, IPTO has noted.
The project will include two converter stations, one at a location near Corinth, the other on Kos, as well as two subsea HVDC cables covering a total of 380 kilometers. IPTO is also developing two sections of a grid interconnection for the Cyclades islands, which will link this group of islands with the mainland.
