On 12 December 2025, the European Investment Bank approved €490 million in debt financing for IPTO’s North East Aegean Interconnection project, which will connect the islands of Lemnos, Lesvos, Chios, Samos and Skyros to Greece’s mainland grid via 150 kV AC submarine cables and 150 kV GIS substations. This financing package supports the multi‑phase North Aegean Interconnection programme, including the Phase C Chios–Samos transmission link that completes the interconnection loop between the islands and the mainland system.
