Greek electricity transmission system operator ADMIE has started preparations to launch tenders to offer contracts for the development of an electricity interconnection linking the Dodecanese islands with the mainland. Tenders are expected to be launched in 2024.

These tenders are related to the cable sections and two converter stations of the Corinth-Kos interconnection, to serve as the main line linking this group of 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.

Once completed, the Dodecanese islands link will replace six independent networks covering the energy needs of these islands. Besides providing a link to the mainland, the Dodecanese island’s interconnection will also facilitate greater RES penetration.

The project will include two converter stations, one at a location near Corinth and the other on Kos island, as well as two subsea HVDC cables covering a total of 380 kilometers.
