The laying of the new 150 kV submarine power cable between Kefalonia and Lefkada, part of the 99.8 million euro upgrade of the Ionian Islands interconnections, was completed using four specialised cable-laying vessels, including the DP-II Atalanti. The new 14.8 km Lefkada–Kefalonia link will enhance the energy security and reliability of the electrical network for Kefalonia, Zakynthos and Lefkada, while also incorporating optical fibres for telecommunications use.
