blackout

Millions lost power as Cuba’s fifth nationwide blackout of 2026 hit amid a US-imposed oil blockade.

Cuba’s national power grid has collapsed, plunging the island into its third nationwide blackout in less than 10 days and leaving approximately 10 million people without electricity.

The outage began around 11am local time (15:00 GMT) on Tuesday, when the country’s entire power grid went offline, according to the state-run electricity company, UNE.

“There has been a total disconnection of the electrical system,” Cuba’s Ministry of Energy and Mines said on social media.

The latest blackout comes as Cuba faces its worst economic crisis in decades, worsened by an oil blockade imposed by the United States that has deepened fuel shortages and pushed the island’s ageing power system to the brink.

US President Donald Trump imposed the blockade in January after the United States removed Venezuelan President Nicolas Maduro from power. Venezuela had long been Cuba’s main supplier of subsidised oil, and under US pressure, Mexico also halted fuel shipments to the island.

As of 2023, according to the International Energy Agency, Cuba was producing only about 40 percent of the oil it consumed, leaving it heavily reliant on imported fuel.

The Trump administration says the measures are intended to pressure Cuba’s communist government to hold democratic elections and release what it calls political prisoners.

The repeated blackouts have fuelled growing frustration across the island. Just a week ago, scattered protests broke out across Havana, with residents banging pots and pans and shouting “turn on the lights” as millions endured another prolonged outage. In both of last week’s blackouts, it took over 24 hours to restore power across the island.

Cuban authorities have struggled for months to keep the lights on as fuel shortages and an ageing electricity grid, much of it dating back to the 1960s and 1980s, leave the system increasingly prone to collapse.

Havana blames the crisis on the US fuel blockade, while Washington says Cuba’s communist government is responsible for the country’s deteriorating power system.

Speaking at a UN General Assembly debate on US sanctions last week, US Ambassador Michael Waltz said Cuba’s leaders were to blame for the electricity shortages.

“Change your ways and turn the lights back on for your people,” he said.

People in Cuba already faced an ongoing economic and humanitarian crisis, largely due to a US blockade.

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”.
