Three times in a single month, the lights went out across an entire country.
Not a neighbourhood. Not a city. An entire island of 11 million people — hospitals, schools, water systems, homes — plunged into total darkness. Three times in March 2026 alone, Cuba's national electric grid has collapsed completely. And the situation is getting worse, not better.
What is happening in Cuba right now is one of the most severe humanitarian energy crises in the Western Hemisphere in decades. Here is the full story — what caused it, how bad it really is, and what it means for the region and the world.
Three Blackouts in One Month — What Happened
On March 4, 2026, a failure at the Antonio Guiteras Power Plant in western Cuba triggered the first major outage of the month, cutting power to millions in Havana and surrounding provinces.
On March 16, the national grid collapsed again — a complete disconnection of the entire Cuban electrical system. It took several days to fully restore power across the island.
Then, on March 21, it happened a third time. At 6:32 PM local time, the state utility Union Electrica posted a single message on social media: "A total disconnection of the National Electric Power System occurred. We will continue to provide updates." That was it. Within minutes, the lights were out in Havana, Matanzas, Holguin and every other province across the island.
By the following morning, only 72,000 customers in the capital had electricity restored — a tiny fraction of Havana's population of approximately two million. Five hospitals were among the priority reconnections. Across the rest of the island, millions remained in darkness.
This is no longer an energy problem. It is a full-blown national crisis.
The Root Cause: A Perfect Storm
To understand why Cuba's grid keeps collapsing, you need to understand three separate but connected problems that have converged at the worst possible time.
Problem One: A Crumbling Infrastructure
Cuba's electricity infrastructure was built largely in the Soviet era and has been deteriorating for decades. The country has never had the foreign currency needed to properly maintain, upgrade, or replace its ageing thermoelectric plants. The heavy oil these plants burn has a high sulphur content that actively corrodes the equipment over time. Engineers working on the grid have been described — in a phrase that tells you everything — as "magicians to keep it running at all, given the shape that it's in."
Even without any external pressure, Cuba's grid was already on borrowed time.
Problem Two: The Venezuela Collapse
For years, Venezuela was Cuba's most important economic lifeline — providing oil on deeply discounted terms in exchange for Cuban doctors, teachers, and security personnel. That relationship sustained Cuba through years of US sanctions and economic stagnation.
That lifeline ended abruptly in January 2026 when the United States arrested Venezuelan President Nicolás Maduro in an early-morning raid — a story covered extensively as US military forces captured Venezuela's president — and charged him with drug trafficking. With Maduro removed, Venezuelan oil shipments to Cuba stopped immediately. The country that had been Cuba's most reliable supplier was no longer in a position to supply anything at all.
Problem Three: Trump's Oil Blockade
In late January 2026, President Trump signed Executive Order 14380, imposing a direct oil blockade on Cuba, warning any country in the world that sells or provides oil to the island of punitive tariffs and sanctions. The order went further than any previous US economic measure against Cuba.
The effect was swift and devastating. Cuba produces only about 40% of the petroleum it needs to power its economy. The remaining 60% had to come from imports. With Venezuela cut off and Trump threatening any other potential supplier with trade punishment, those imports dried up almost immediately.
Cuba's Vice Minister of Energy confirmed the scale of the disaster directly: the island has gone three consecutive months without receiving a single shipment of diesel, fuel oil, gasoline, aviation fuel, or liquefied petroleum gas. Not one shipment. In three months.
Life Inside the Blackout
The numbers tell one story. The human reality tells a darker one.
Surgeries have been postponed for tens of thousands of patients. Hospitals are running on emergency microgrid power. Fuel for vehicles is strictly rationed — you cannot simply fill your tank. Multiple airlines, including Air Canada, have suspended flights to Cuba entirely, citing fuel shortages. Employers across the island have reduced working hours because there is no power to run workplaces. Farmers cannot get produce to market. Schools are disrupted.
People are spending their evenings on the Malecon seafront — Havana's famous waterfront boulevard — not by choice but because it is too dark and too hot to be indoors. "We have to get used to continuing our usual routine," said one 35-year-old vendor to the Associated Press. "What else can we do? We have to try to survive. Get used to events, with or without electricity."
That sentence — the resignation in it, the exhaustion — captures something important about what daily life in Cuba looks like right now.
The government has had to establish "micro-islands" of emergency generating power to keep the most vital centres — hospitals, water systems — running at minimum capacity. Everything else is darkness.
Trump's Position and the Threat of "Taking" Cuba
The US government has been explicit about its objectives. The Trump administration is demanding that Cuba release political prisoners and move toward political and economic liberalisation as conditions for lifting the blockade. Behind the scenes, the US is also said to be looking for Cuban President Miguel Díaz-Canel to step aside entirely.
But Trump's public statements have gone well beyond standard diplomatic pressure. In mid-March, speaking from the White House, he said openly: "You know, all my life I've been hearing about United States and Cuba — when will the United States have the honour of taking Cuba? Taking Cuba in some form, yeah, taking Cuba — I mean, whether I free it, take it, I think I can do anything I want with it."
When asked whether a move on Cuba would involve military force similar to the operation that removed Maduro, Trump did not rule it out.
Cuba's Deputy Foreign Minister Carlos Fernandez de Cossio responded directly on international television: "We don't believe it is probable, but we would be naive if we do not prepare." The Cuban government has also said it is "historically ready to mobilise as a nation for military aggression."
This is the language of two countries edging toward confrontation — not just economic pressure.
The Broader Geopolitical Picture
Cuba's crisis does not exist in isolation. It is one piece of a rapidly shifting geopolitical landscape in which the United States under Trump is simultaneously managing multiple high-stakes confrontations.
Cuba's oil blockade fits into this same pattern: an American administration using energy as a weapon across multiple theatres simultaneously. Venezuela was removed. Iran is being bombed. Cuba is being squeezed. The common thread is oil, leverage, and a willingness to use economic and military force as tools of political change.
The UN Secretary-General António Guterres has said he is "extremely concerned" about the humanitarian situation in Cuba, warning it "will worsen, or even collapse" if the country's oil needs are not met. UN experts have described Trump's executive order imposing the oil blockade as "a serious violation of international law." Belarus, Iran, Spain, Vietnam, and the African Union have all expressed support for Cuba. Humanitarian activists have announced plans for a convoy — called the Nuestra América Convoy — to attempt to break the US blockade and deliver aid to the island.
In a small concession, the Trump administration issued a limited license in late February allowing companies to resell Venezuelan oil specifically to Cuba's private sector — but with strict conditions that the exchange must "support the Cuban people, including the private sector" rather than the government. Cuba has also announced the release of 51 political prisoners in what it called a gesture of goodwill following engagement with the Vatican. But neither of these steps has translated into restored oil supplies at the scale the island requires.
Can Cuba Survive This?
Experts are divided — but the outlook is not optimistic.
Cuba could theoretically struggle on by dramatically cutting consumption and rapidly expanding solar power. The country actually made significant progress in solar installation last year. But scaling that up fast enough to replace oil-based generation would require urgent assistance from China and other partners at a level that has not yet materialised. Even if it did, the living conditions involved would be, in the words of one expert, "constant misery for the general population."
The worst-case scenario is a complete economic collapse followed by social chaos and mass migration — a humanitarian disaster of a scale the region has not seen in a generation.
What is certain is that the current situation is not sustainable. Three full grid collapses in one month, hospitals running on emergency power, surgeries being postponed, airlines refusing to land — this is a country in acute distress.
Whether that distress leads to political change in Havana, a negotiated settlement with Washington, a humanitarian intervention, or something more dangerous depends on decisions being made right now by leaders on both sides of an old and unresolved conflict.
For the 11 million people living on the island, those decisions cannot come quickly enough.
