Cuba: fire takes Santa Cruz power plant unit 1 offline
Cuba’s Unión Eléctrica (UNE) reported unit 1 of the Ernesto Guevara power plant offline because of a fire on 16 October 2026. The plant is in Santa Cruz del Norte, Mayabeque. The report confirms a generating-unit shutdown; its effect on household electricity supply has not been quantified.

Martí Noticias reports the fire controlled and says its contact with the plant confirmed no injuries.
Damage, the latest operating status and a return-to-service date remain unknown.
What the operator reported
UNE’s statement was published at 11:46:01 UTC on 16 October, equivalent to 7:46 am in Cuba. It says the machine was offline because of a fire and firefighters were at work. This describes the situation at publication. It does not establish the generating unit’s operating condition at the time a reader opens this article.
Martí Noticias separately reports contacting the plant, which confirmed no injuries. The outlet reports that the fire was controlled, while damage and the return to service remain unresolved. Its direct plant contact supports the injury report; it should not be treated as independent confirmation of every detail relayed from UNE.
What the sources tell us, and what they do not
- Location
- Santa Cruz del Norte · Mayabeque · Cuba
- Confirmed equipment impact
- UNE reported Ernesto Guevara plant unit 1 offline following a fire
- Household impact
- Not quantified in the verified evidence
- Return to service
- Latest operating status and return date unknown
What this establishes about electricity supply
The loss concerns one generating unit. The available evidence does not establish how many households lost electricity because of this fire, a citywide outage or a nationwide grid collapse. The latest unit operating status and a return date remain unknown. A plant shutdown alone is insufficient to identify the status of an individual electricity connection.
EFE attributes a 6:55 am Cuba-time fire onset to UNE. It also reports a forecast of 2,190 MW of interruption at peak demand for the wider electricity system. That forecast is neither a measured current outage total nor a quantified consequence of this unit’s shutdown. It cannot be converted into an affected population or household count.
Planning for essential devices
The backup essentials guide, internet backup planner and runtime calculator help readers compare essential devices and backup capacity. They support preparation, but cannot check a local connection, identify the cause of a particular interruption or predict when the plant will return to service.
