Cuba's power grid has reportedly collapsed, following months of rolling blackouts as the island nation has struggled with an energy crisis brought on by a U.S. blockade.

According to Reuters, Cuba's grid operator reported the countrywide grid collapse around midday on July 6, leaving 10 million people without power. Prior to that, nearly two-thirds of Cuba had already lost power to their homes.

Cuba's energy minister said in mid May that the country had run out of oil and diesel, and warned that the island's energy system had reached a "critical state." Those struggles have been compounded by aging power infrastructure, straining transportation networks, hospitals and a range of other essential services. The U.S. also halted all oil shipments to Cuba in January, while enacting crippling sanctions that have left the country with few alternatives to replenish its fuel supplies.

U.S. political pressure has been centered around a stated goal to unseat Cuba's government, similar to how the U.S. military ousted and arrested Venezuela's President Nicolas Maduro in January 2026. In months since the U.S. blockade began, Cuba has become increasingly dependent on dwindling fuel reserves and limited outside assistance, leaving its aging power grid vulnerable to repeated large-scale failures whenever fuel supplies or electricity generation have fallen short.
