In February 2026, IPTO (ADMIE) commenced installation of the new 150 kV subsea cable between Lefkada and Cephalonia as part of the upgrade of the Ionian Islands’ electrical interconnections. The DP II Atalanti cable‑laying vessel arrived in the Ionian Sea to begin the critical phase of laying the new submarine cable in the strait between Cephalonia and Lefkada, a month‑long operation involving divers working at depths exceeding 300 metres to position the cable with high precision.
