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.
