Status:Operational
Type:island link
The Nisyros–Tilos submarine interconnector is an existing short AC undersea cable that supplies electricity to the island of Tilos from the neighbouring island/main system of Kos via Nisyros in the Dodecanese archipelago. In practice the link carries oil‑fired generation from Kos (transmitted through Nisyros) and provides the principal external supply...

Oct 2016Major Outage
In October 2016, a major outage occurred on the 20 kV undersea interconnector supplying Tilos from the oil‑fired power station on Kos via Nisyros, when persistent cable faults led to a blackout on Tilos lasting about 7.5 hours; this event is cited as the most severe of the recurring blackouts caused by the unreliable Kos–Nisyros–Tilos submarine cable link.
1989Cable Installation Complete
According to DEDDIE’s network development appendices, the medium-voltage submarine interconnection between Nisyros and Tilos consists of two 20 kV cables (3 x 35 mm² Cu), each 16,000 m long for a total of 32,000 m, listed with a construction year of 1989, indicating that installation of all planned interconnector cables was completed in 1989.
1989Commercial Operations Full Power
The DEDDIE network development plan lists a medium-voltage (20 kV) submarine interconnection between Nisyros and Tilos, consisting of two 3x35 mm² copper cables with a total length of 32 km, with the year recorded as 1989, indicating that this link has been in operational service since that time as part of the Rhodes distribution area network.
