Cuba Suffers Third Nationwide Power Blackout Amidst Energy Crisis

Cuba has suffered its third nationwide power blackout since the start of the year, as the country’s fuel reserves diminish and its electric grid crumbles due to an energy crisis precipitated by the US fuel blockade.

The blackout in the country of nearly 10 million people was reported on Monday by the state-run Electric Union, which said that the cause is under investigation.

Cuba’s Energy and Mines Minister Vicente de la O Levy said protocols were quickly activated to restore electricity throughout Cuba after the outage.

“Vital services continue to be protected, amidst this complex situation exacerbated by the energy blockade we face,” he said.

Grid operator UNE said it was providing electricity to some vital services, including hospitals and food production centres, but by late afternoon was able to serve only 1 percent of the capital, Havana’s, ⁠demand.

Cuba was already struggling with fuel supplies before US President Donald Trump cut off oil deliveries from Venezuela to the island in January. But Trump’s actions, including threatening tariffs on any country that sells or provides oil to Cuba, have made things significantly worse, and deepened the island’s financial crisis. As a result, blackouts and power cuts have accelerated.

Since January, Washington has only allowed one oil tanker, from Russia, to pass its blockade and dock in Cuba, as part of a sanctions campaign aimed at ending more than six decades of communist government in Havana.

Trump has pointed to the US abduction of Venezuela’s socialist president, Nicolas Maduro, in January, and his replacement with a successor that can be pressured to work with the US, as a potential blueprint for Cuba.

Cuban President Miguel Díaz-Canel accused the US of trying to “incite social unrest by strangling Cuba’s fuel supply”.

“The actions of electrical workers in the midst of a genocidal energy blockade are heroic,” he wrote on social media.

The blackout is the eighth on the island of 9.6 million people since late 2024. It comes as the state imposes power cuts across the country – over 30 hours straight in parts of Havana and over 70 hours in some rural areas – in a desperate attempt to preserve fuel.

“Living like this is agony,” Meyboll Font, a 51-year-old self-employed social media community manager, told the AFP news agency.

Font said her Havana neighbourhood has been surviving on just “three or four hours of power a day”, but that the blackout was worse because “you never know when it [electricity] will return”.
