Cuba on Monday suffered its third nationwide power outage since the start of the year, the state electricity company said. The impoverished island was already struggling to keep the lights on before the US president, Donald Trump, imposed an oil blockade in January, which has depleted the already dwindling supply of fuel for Cuba's power plants.
Power grid collapse
“There has been a total disconnection from the national electricity generation system,” the UNE power utility wrote on X, adding that it was investigating the causes. The blackout is the eighth on the island of 9.6 million people since late 2024.
The state has imposed increasingly draconian power cuts across the country – over 24 hours at a stretch in parts of Havana and over 70 hours in some rural areas – in an increasingly desperate attempt to conserve fuel.
Aging infrastructure and fuel blockade
Power outages have been a feature of life for years on the communist-run island, where the electricity generation system, composed mainly of ageing Soviet-era plants, is in shambles. The pace of blackouts has accelerated since the fuel blockade began, however, with authorities citing a lack of fuel to run the generators that support the creaking national grid.
Since January, Washington has only allowed one oil tanker, from Russia, to dock in Cuba. The blockade, coupled with a flurry of sanctions on the Cuban state and foreign companies that do business with it, have tipped the country closer to the brink of collapse. Food, drinking water and medicine are in increasingly short supply, prompting the UN to warn of a humanitarian emergency.
Solar energy efforts
The government has invested heavily in solar energy to try to alleviate the electricity shortages but solar power, while increasing, still represents just 10% of the energy mix.
