Island-wide blackout hits Cuba as island struggles with deepening energy crisis

Mar 16, 2026 | 12:14 PM

HAVANA (AP) — Officials in Cuba reported an island-wide blackout Monday in the country of some 11 million people as its energy and economic crises deepen and its power grid continues to crumble.

The Ministry of Energy and Mines on X noted a “complete disconnection” of the country’s electrical system and said it was investigating, noting there were no failures in the units that were operating when the grid collapsed.

It was the third major blackout in Cuba over the past four months.

Tomás David Velázquez Felipe, a 61-year-old resident of Havana, said the relentless outages make him think that Cubans who can should just pack up and leave the island. “What little we have to eat spoils,” he said. “Our people are too old to keep suffering.”

Cuba’s aging grid has drastically eroded in recent years, leading to an increase in daily outages and island-wide blackouts. But the government also has blamed its woes on a U.S. energy blockade after President Donald Trump in January warned of tariffs on any country that sells or provides oil to Cuba. The Trump administration is demanding that Cuba release political prisoners and move toward political and economic liberalization in return for a lifting of sanctions.

William LeoGrande, a professor at American University who has tracked Cuba for years, said the country’s energy grid hasn’t been maintained properly and its infrastructure is “way past its normal useful life.”

“The technicians working on the grid are magicians to keep it running at all given the shape that it’s in,” LeoGrande said.

LeoGrande said that if the island drastically reduces consumption and expands renewables, it can struggle along for a while without oil shipments. “But it would be constant misery for the general population, and eventually, the economy could collapse just completely and then you would have social chaos and probably mass migration,” he said.

To ramp up solar power even faster than Cuba did last year, LeoGrande said other countries, principally China, would have to be willing to double or more their provision of such equipment.

President Miguel Díaz-Canel on Friday said the island had not received oil shipments in three months and was operating on solar power, natural gas and thermoelectric plants, and that the government has had to postpone surgeries for tens of thousands of people.

Yaimisel Sánchez Peña, 48, said she was upset that the food she buys with money that her son in the U.S. sends keeps spoiling, adding that the outages also affect her 72-year-old mother: “Every day, she suffers.”

Mercedes Velázquez, a 71-year-old Cuban resident, lamented yet another blackout. “We’re here waiting to see what happens,” she said, adding that she recently gave away part of a soup she made while it was still fresh so as not to throw it out. “Everything goes bad.”

A massive outage over a week ago affected the island’s west, leaving millions without power. Another major blackout affected western Cuba in early December.

Critical oil shipments from Venezuela were halted after the U.S. attacked the South American country in early January and arrested its then-president, Nicolás Maduro.

While Cuba produces 40% of its petroleum and has been generating its own power, it hasn’t been sufficient to meet demand as its electric grid continues to crumble.

“And on top of all that, the Cuban government doesn’t have the hard currency to import spare parts or upgrade the plant or grid itself. It’s just a perfect storm of collapse,” LeoGrande said.

He noted that the thermoelectric plants also have been using heavy oil, whose sulfur content is corroding the equipment.

On Friday, Díaz-Canel confirmed that Cuba was holding talks with the U.S. government as the problems continue to deepen.
