You never know when electricity will return
For the third time in six months, Cuba's entire electrical grid has gone dark, leaving 9.6 million people suspended in an uncertainty that is itself a form of suffering. The immediate cause is a US oil blockade imposed in January, which has reduced fuel supplies to near nothing for an aging Soviet-era infrastructure already long past its limits. What unfolds in Havana and across the island's rural reaches is not merely a technical failure but a slow humanitarian unraveling — one where the absence of light becomes the absence of work, medicine, water, and the small dignities of daily life.
- A US oil blockade imposed in January has reduced Cuba's fuel imports to a single Russian tanker in six months, pushing an already fragile grid past the point of function.
- Nine point six million people are living through blackouts that stretch beyond 70 hours in rural areas — not rolling interruptions, but prolonged erasures of electricity, refrigeration, water, and medical equipment.
- The uncertainty is its own crisis: residents who could once plan around scheduled cuts now wait without knowing when, or whether, power will return.
- The UN has escalated its language to 'humanitarian emergency' as food scarcity, water access, and medicine shortages compound the energy collapse.
- Cuba's investment in solar energy has reached 10 percent of its energy mix — a real but insufficient buffer against a blockade that has made the remaining 90 percent nearly impossible to fuel.
Cuba's power grid collapsed again on Monday — the third total blackout in six months — and the 9.6 million people living through it already understood the reason before any official explanation arrived. There was simply no fuel left.
The island's electricity infrastructure, built mostly on Soviet-era plants that should have been decommissioned decades ago, had been deteriorating for years. But the crisis sharpened dramatically in January when the Trump administration imposed an oil blockade. Since then, only one Russian tanker has been permitted to dock. The arithmetic was merciless: less fuel, less power, and a government forced into ever more severe rationing.
In Havana, residents had already adapted to surviving on three or four hours of electricity a day. Meyboll Font, a 51-year-old self-employed social media manager, described the situation in a single word: agony. The particular cruelty of a total grid failure, she explained, was the uncertainty — when you know power will return, you can plan around it; when you don't, you simply wait. A young software programmer working remotely for a tourism startup was more direct: without electricity and wifi, work was impossible.
This was the eighth blackout since late 2024, but the pace had accelerated. Cuts now lasted more than a full day in parts of Havana and beyond 70 hours in rural regions — not brief interruptions but extended absences that dismantled everything: communication, refrigeration, water pumps, medical equipment. The UN had begun using the language of humanitarian emergency, the kind reserved for situations where basic survival grows uncertain.
Cuba had invested in solar energy as a partial escape, bringing it to roughly 10 percent of the island's energy mix. It was a meaningful step, but nowhere near enough to replace the fuel-dependent plants the blockade had effectively idled. The lights would return eventually — they always did. But no one knew when, and that not-knowing had become its own kind of darkness.
Cuba's power grid collapsed again on Monday, marking the third time in six months that the entire island went dark. The state utility announced the total disconnection from the national system without immediately explaining why, but the cause was already well understood by the 9.6 million people living through it: there was simply no fuel left to run the generators.
The island had been fragile for years. The electricity infrastructure, mostly Soviet-era plants that should have been retired decades ago, had never fully recovered from the Cold War's end. But the crisis accelerated sharply in January when the Trump administration imposed an oil blockade, cutting off the fuel that kept the system limping forward. Since then, only one Russian tanker has been permitted to dock. The math was brutal: less fuel meant less electricity, which meant the government had to ration power in increasingly severe ways.
In Meyboll Font's Havana neighborhood, residents had already adjusted to surviving on three or four hours of electricity per day. A 51-year-old who works as a self-employed social media manager, Font described the situation with a single word: agony. The difference between scheduled blackouts and a total grid failure, she explained, was the uncertainty. When you know the power will return at a specific time, you can plan. When you don't know, you're simply waiting. A young software programmer in another part of the city, working remotely for a tourism startup, put it more plainly: without electricity and wifi, work became impossible.
This was the eighth blackout since late 2024, but the frequency had accelerated dramatically. The government, desperate to conserve fuel, had begun imposing cuts that lasted more than a full day in parts of Havana and stretched beyond 70 hours in rural areas. These were not rolling blackouts—brief interruptions that allowed people to adjust. These were extended absences of power that disrupted everything: work, communication, refrigeration, water pumps, medical equipment.
The blockade had compounded an already fractured economy. Sanctions on the Cuban state and foreign companies doing business with it had tightened the squeeze. Food was becoming scarce. Drinking water was harder to access. Medicine was running low. The United Nations had begun warning of a humanitarian emergency, the kind of language reserved for situations where basic survival becomes uncertain.
The government had tried to build its way out of the crisis by investing in solar energy, but progress was slow. Solar now accounted for roughly 10 percent of the island's energy mix—a meaningful increase but nowhere near enough to replace the fuel-dependent plants. For now, Cuba remained trapped between an aging infrastructure it could not afford to replace and a blockade that prevented the fuel needed to keep it running. The lights would come back on eventually. They always did. But no one knew when, and that uncertainty had become its own kind of darkness.

Why does this matter beyond Cuba itself? It's one island's power problem.
Because it shows what happens when an economy is cut off from fuel and has no way to adapt quickly. Nine million people can't just switch to solar overnight. They're living in real time with the consequences of that gap.
The blockade is the obvious culprit, but you mentioned the infrastructure was already broken. How much of this is Trump's policy versus Cuba's own problems?
Both are true. The grid was failing before January. But the blockade accelerated the timeline dramatically. It took a chronic problem and made it acute.
What does 70 hours without power actually mean for a person? Not abstractly—what happens?
Your refrigerator stops. If you have medicine that needs to be cold, it spoils. If you work from home, you can't. If you're a hospital, you're running on generators you can't fuel. If you need water, the pump doesn't work. It's not an inconvenience. It's a disruption of the systems that keep people alive.
The government invested in solar. Why isn't that working?
Solar takes time and money to scale. You can't build enough capacity in months to replace what fuel plants provided. Ten percent is real progress, but it's not salvation.
What's the endgame here? Does this get better?
Not without either the blockade lifting or a massive external investment in new infrastructure. Right now, Cuba is trapped. The fuel won't come, the old plants can't be replaced, and people are living in the gap.
