Onshore construction for the upgrade of the Kefalonia–Zakynthos interconnector moved into active phase in early 2026, with initial works taking place at Mounda beach on Kefalonia, where the new 150 kV high-voltage submarine cable will make landfall. The project, led by ADMIE, involves installing new submarine and underground cables and integrating optical fibres over a 20.4 km route between Kefalonia and Zakynthos (plus the parallel Lefkada–Kefalonia link), following earlier preparatory and underwater survey works carried out by the DP‑2 vessel Astrea using ROV mapping of the existing PPC cable to identify a safe route and landfall points.
