Late Development Other

IPTO adopted the mixed HVDC/HVAC "Scenario B" configuration for the Dodecanese and Northeast Aegean island interconnections, confirming that the Chios–Samos section will be implemented as a 150 kV AC single‑circuit submarine interconnector of about 100 km length and 250 MVA capacity using one three‑core cable. This system‑level design decision superseded the earlier 220 kV double‑circuit option and defines the technical concept for the Northern Aegean Interconnection Phase C: Chios–Samos ahead of detailed engineering and procurement.
