Chios: two island-wide power cuts on the evening of 7 November, the second lasting about an hour and a half

The island of Chios, in the north-eastern Aegean, lost electricity twice on the evening of Saturday, 7 November. According to the local website chiosnews.com, an island-wide outage occurred at around 17:15 and power returned at 17:50. A new outage began at 20:20 and this time lasted about an hour and a half.

The cause. According to the website Astraparis, which says it gathered information from its own sources, the 20:20 outage was due to a fault at the PPC (ΔΕΗ) thermal power plant at Kontari, which supplies the island. Chiosnews.com notes that there was no information about the cause and that the weather was not extreme. The sources consulted do not include a statement from PPC or from the distribution operator HEDNO (ΔΕΔΔΗΕ) about the incident.

Context. Chios is not connected to the mainland power system, and island-wide outages have recurred over the past year. Astraparis reported an island-wide outage on 30 August 2026, also attributed to a fault at Kontari, and ERT reported in December 2025 an outage caused by a fault at the PPC plant that left Chios, Oinousses and Psara without power. In October, the Chios association of food-service businesses called for a clear compensation procedure after HEDNO replied that each claim must be documented individually and linked to a specific network incident.

What comes next. According to a reply from the Ministry of Environment and Energy dated 13 October 2026, cited by politischios.gr, the electrical interconnection of Chios with the mainland system is scheduled for completion in 2030. A member of parliament elected in Chios has asked, through a parliamentary question, for the updated timetable, the budget and the status of the project’s contracts.
