The Corinth–Kos 320kV HVDC island interconnection project, led by Greek independent transmission operator IPTO, is one of the largest Mediterranean cross-sea power projects in recent years. It has a total capacity of 1 GW, with 1,260 km of submarine cables and 30 km of onshore cables. It will link mainland Greece with the Dodecanese islands to stabilise local power supply and boost consumption of local solar and wind power. As a subcontractor within the Hellenic Cables + Asso.subsea consortium, Nexans will supply 420 km of 110kV mass-impregnated (MI) oil-filled submarine cables. MI oil-filled cables remain highly reliable for long-distance, deep-water cross-sea applications. The order will keep Nexans’ MI production lines occupied, with production running from late 2026 to mid-2028. Subsea site surveys have already commenced. Market signal: Demand for Mediterranean island grid upgrades and cross-border power interconnections keeps rising. Oil-filled subsea cables have not been fully replaced by XLPE and maintain stable demand for certain long-distance subsea scenarios.
