Cuba hit by nationwide blackout after grid fault and poor weather
Millions of people in Cuba were left without power on Friday after the country's electricity grid suffered a total disconnection, triggering a nationwide blackout. The outage affected the entire system and prompted gradual restoration efforts later in the day. Power began returning to some priority areas, including locations near hospitals and water pumping stations in Havana, according to the grid operator.

The energy ministry said the blackout began just before 14:00 local time on Friday, which was 18:00 GMT. The grid operator said the immediate cause was a transmission fault combined with poor weather conditions in central Cuba. Felix Estrada, the operator's national load dispatch director, said protocols for a gradual restoration of electricity were activated and that the process was still under way on Saturday.
The blackout is at least the sixth partial or total outage to hit Cuba this year, underscoring the strain on the island's power system. Ageing electricity infrastructure and chronic fuel shortages have already weakened the grid, while reliance on imported fuel has made the system more vulnerable to external pressure. The latest disruption also added to difficulties for hospitals, schools and government offices, which have faced repeated interruptions to normal operations during earlier outages.
The incident matters because electricity shortages in Cuba have become a broader economic and humanitarian problem, not just a technical one. Food and medicine have become scarcer, and repeated blackouts have affected water supply, cooking fuel access and the ability of public services to function. The latest outage therefore adds to pressure on households and institutions already dealing with limited resources and recurring disruption.

Cuba's power crisis has been building for some time, with repeated failures exposing the fragility of the national grid. The country has blamed its fuel crisis on sanctions and restrictions on oil shipments, while also pointing to wider shortages in imported energy supplies. The repeated blackouts have also prompted rare protests, reflecting the social strain caused by prolonged disruption to daily life.
What remains unclear is how quickly full power will be restored across the island and whether the grid can avoid further failures in the near term. Officials have said restoration is continuing, but no timetable for complete recovery has been given. The key issue to watch is whether the latest outage leads to more disruption in Havana and other priority areas, and whether it deepens pressure on Cuba's already strained energy system.
