Cuba is hit by another islandwide power outage as its national electricity system collapses, marking the third nationwide blackout in less than 10 days, according to officials and reporting from multiple outlets. The blackout leaves the country without power for a widespread period before restoration begins in some areas, with timelines varying by report.

Several sources link the repeated failures to a combination of fuel shortages and grid deterioration. They describe low fuel reserves and an aging, fragile power infrastructure that makes the system vulnerable to breakdowns. Reporting also highlights that the situation is occurring amid Cuba’s broader economic stress and a U.S.-linked fuel constraint that began in January, when the U.S. threatened tariffs related to oil sales to Cuba, and that later shaped the island’s access to energy.

Cuban President Miguel Díaz-Canel attributes the crisis to U.S. actions aimed at restricting fuel supply, while other coverage focuses on the technical and supply challenges affecting generation and distribution. Across outlets, authorities report that the National Electric System (SEN) goes completely offline and that service is gradually restored.
