Cuba experienced an islandwide power outage, according to reports, as the electrical grid failed amid deepening energy constraints. The crisis was linked to a dwindling supply of fuel needed to generate electricity, alongside chronic mechanical problems affecting power plants and distribution.

Officials said the blackout left large parts of the island without power and that restoration efforts were underway but could take time. State media and emergency messaging indicated that the government was working to restart parts of the system in stages, but that the underlying shortages would continue to hamper sustained electricity supply.

The outage adds to a cycle of repeated blackouts in recent months that have disrupted water pumping, refrigeration, transportation, communications, and other essential services. Residents described the experience as worsening daily hardships in an economy already strained by shortages and rising costs.
