he Independent Power Transmission Operator (ADMIE) has drafted a preliminary 10-year development plan for the period 2021-2030 – which is currently under consultation – with a budget of 4.4 billion euros, which envisages the electricity interconnection of the North Aegean islands using underwater cables, a project worth 935 million euros.
This project will be implemented in parallel with the interconnection of the Dodecanese islands, worth 1.477 billion euros, in three stages: the first linking Corinth-Kos and Kos-Rhodes, Nea Santa-Lemnos and Lemnos-Lesvos to be completed in 2027, the second, linking Aliveri-Skyros and Lesvos-Chios, Kos-Samos and Rhodes-Karpathos to be completed in 2028 and the third, closing all interconnecting links by 2030.
The 10-year programme also envisages strengthening the interconnection of Ionian Islands, completing the expansion of a 400 kV system in Peloponnese and strengthening a 400 kV system in East Macedonia and Thrace.
The programme also envisages construction of a second line between Greece and Bulgaria, to be included in the European System in early 2023. ADMIE also examines an upgrade of existing or development of new interconnections with the neighbouring systems of North Macedonia and Turkey.
