TLDR

Cuba's power grid collapsed on Saturday — the third nationwide blackout this month and second in a week. The country has not received foreign oil for three months following US threats of tariffs against any nation supplying fuel to Cuba. President Trump has suggested Cuba's government is near collapse and he may soon have 'the honour of taking Cuba.'

On Saturday, Cuba's power grid collapsed for the third time this month. Eleven million people went dark.

That is every Cuban citizen. That is a complete national failure of the most basic infrastructure modern life requires.

## The arithmetic of strangulation

Cuba produces approximately 40 percent of the oil it needs to run its economy, which means it imports 60 percent, which means when imports stop, the country loses more than half its energy capacity in a matter of weeks. The immediate cause of Saturday's collapse was a failure at the Nuevitas thermoelectric plant in Camagüey, where ageing Soviet-era turbines cascaded into shutdown like dominos falling across a factory floor. The deeper cause is simpler. Cuba has not received foreign oil in three months.

Zero shipments. Zero barrels.

In January, President Trump warned of tariffs against any nation selling oil to Cuba, and the warning worked with the efficiency of a threat issued by someone who has demonstrated he will follow through. Venezuela, which had shipped roughly 100,000 barrels daily to Havana for two decades under preferential terms, stopped. Other potential suppliers did the arithmetic: losing access to American markets in exchange for Cuban goodwill made no commercial sense.

The energy minister calls this a blockade. The US calls it use.

The distinction matters less when you are the one in the dark.

## What darkness means

Cuba's 11 million people were already enduring blackouts of up to 12 hours daily before Saturday's total collapse. That is 132 million person-hours of darkness per day. That is 132 million hours when surgical operations are cancelled, when insulin spoils in warm refrigerators, when businesses lose output they cannot recover, when elderly people in apartment blocks without elevators sit trapped in heat that kills.

Per capita, each Cuban lost half their waking day. Every day.

The Cuban Electric Union responded to Saturday's collapse by activating what they call 'micro-islands,' isolated generating units that provide power to hospitals, water systems, and critical facilities while the main grid stays dead. It sounds technical and competent when you read it in a press release. (It is neither.) Micro-islands are triage. They are the acknowledgment that the system cannot be restored as a whole, only preserved in fragments, the way you might keep a patient alive by routing blood only to the brain while the limbs go cold.

This is not recovery. This is managed decline.

## The strategy of waiting

Trump told reporters after the previous collapse that he believed he would soon have 'the honour of taking Cuba.' The phrase is ambiguous in the way his phrases often are, leaving room for regime change through internal collapse, negotiated transition, or something more direct depending on how events unfold and which interpretation proves convenient. What is not ambiguous is the strategy: apply pressure, wait for failure, let the infrastructure do the work that armies used to do.

It is strategic patience if you support it. It is slow strangulation if you do not.

The Cuban government has refused to release political prisoners or liberalize its economy, which is the American condition for lifting pressure, which is precisely the kind of demand that entrenched regimes cannot accept without signing their own termination. The US knows this. Cuba knows this. The standoff continues, measured not in troops or missiles but in kilowatt hours, in barrels of oil that do not arrive, in hours of darkness that accumulate like interest on a debt that compounds daily.

Economic warfare works slowly. It also works.

## The infrastructure death spiral

Infrastructure failure is not linear. It is exponential. Cuba's thermoelectric plants were built with Soviet technology decades ago. They require fuel, obviously, but they also require constant maintenance, replacement parts that Cuba cannot manufacture and increasingly cannot import, and stable operating conditions that cascading blackouts make impossible. Every collapse damages equipment throughout the system. Every partial repair leaves vulnerabilities. Every day without adequate fuel accelerates the decay.

This is an infrastructure death spiral. Once a system enters the spiral, each failure makes the next more likely and more severe, until the question is no longer how to restore function but whether function can be restored at all.

Cuba's grid is deep in the spiral now.

## The people who do not appear in the framework

The 11 million Cubans who lost power Saturday are families trying to keep food from spoiling. They are hospitals trying to keep patients alive through surgery with backup generators that may or may not have fuel. They are elderly people in buildings where elevators do not work and heat kills.

The US says Cuba's government is responsible because it refuses to make concessions. Cuba says the US is responsible because it is deliberately causing the suffering. (Both are correct, which is the tragedy.) The people in the dark do not care much about the argument. They want the lights back on.

Authorities said they were working to restore power. They said the same after the last collapse, and the one before that.

KEY TAKEAWAYS

01Cuba suffered its third nationwide blackout in March, leaving 11 million people without electricity.

02The collapse was caused by a failure at the Nuevitas thermoelectric plant in Camagüey.

03Cuba has received no foreign oil for three months due to US pressure on suppliers.

04The country produces only 40 percent of the fuel it needs to power its economy.

05Trump has suggested he will soon have 'the honour of taking Cuba' as its government weakens.

FREQUENTLY ASKED QUESTIONS

Why is Cuba's power grid failing? 

Cuba has not received foreign oil for three months due to US pressure on suppliers. The country produces only 40 percent of the fuel it needs. Ageing Soviet-era infrastructure requires constant maintenance and fuel that is no longer available.

How many blackouts has Cuba had in March? 

Saturday's collapse was the third nationwide blackout in March 2026, and the second in a single week. Before the total collapses, Cubans were already experiencing daily blackouts of up to 12 hours.

What does Trump mean by 'taking Cuba'? 

Trump has suggested Cuba's government is near collapse and raised the possibility of a 'friendly takeover.' Whether this means regime change through internal pressure, negotiated transition, or direct intervention remains unclear.
