Imagine sitting in pitch darkness for sixteen hours a day. Your refrigerator is off. The meat you spent half your monthly salary on is rotting. The fan that keeps the stifling tropical heat at bay is useless. This isn't a temporary inconvenience. For millions of Cubans, this is daily life.
Cuba is facing its worst energy crisis since the collapse of the Soviet Union. The island's power grid is shattered. Fuel lines stretch for miles. Blackouts are no longer scheduled anomalies; they are the status quo. While the Cuban government points the finger directly at Washington's economic sanctions, the reality on the ground is a mix of geopolitical pressure and decades of internal economic mismanagement.

People want to know why a nation can't keep its lights on. The answer isn't just about politics. It is about a crumbling infrastructure, a lack of cash, and a shifting global oil market that has left Havana stranded in the dark.
The Reality Behind the Cuban Power Collapse
The Cuban power grid relies heavily on seven aging thermoelectric plants. Most of these facilities were built with Soviet technology over four decades ago. They have outlived their operational lifespans. Regular maintenance requires specialized parts and foreign currency. Cuba has neither. TIME has provided coverage on this fascinating issue in great detail.
When the Antonio Guiteras plant in Matanzas—the island's largest power producer—goes offline, the entire country shudders. It happens frequently. The system operates on a knife-edge. The government reports that the country requires around 3,000 megawatts of electricity to meet peak demand. Regularly, the grid suffers from a deficit of over 1,000 megawatts. That means a third of the country is dark at any given moment.
To patch the holes, Havana relies on floating power plants leased from a Turkish company, Karpowership. These powerships sit off the coast, burning expensive fuel to feed the grid. It is an expensive band-aid on a gunshot wound. The state simply cannot afford the fuel to run them at capacity.
How Tightening Washington Sanctions Squeeze the Grid
The Trump administration instituted a "maximum pressure" campaign against Cuba, reversing the Obama-era thaw. The Biden administration maintained most of these measures, keeping Cuba on the State Sponsor of Terrorism list. This designation is a financial death sentence.
Major international banks refuse to process transactions involving Cuba. The country cannot easily access loans or clear payments for essential imports. Buying a spare part for a power plant becomes a logistical nightmare involving shell companies and inflated shipping costs.
Washington also targets shipping companies that transport Venezuelan oil to Cuba. Venezuela has been Cuba's primary energy benefactor for over two decades. Under the Petrocaribe agreement initiated by Hugo Chávez, Caracas swapped cheap crude for Cuban doctors and security advisors. But Venezuela's own oil production has cratered. U.S. sanctions on Venezuelan state oil company PDVSA make it incredibly risky for international tankers to touch Cuban ports. Shipping firms face blacklisting, asset seizures, and massive fines. Fewer tankers arrive. The state refineries sit idle.
The Failure of Internal Economic Policy
Blaming Washington is the Cuban government's default setting. It is a convenient shield. However, critics and independent economists point out that the state's own economic choices crippled the energy sector.
For years, the government heavily subsidized electricity. Cubans paid a fraction of the actual cost of power generation. While this kept bills low for citizens, it stripped the state utility company, Unión Eléctrica, of any revenue needed for reinvestment. The system ran on a deficit for decades.
When the government attempted a currency unification plan in 2021, inflation skyrocketed. The Cuban peso collapsed against the dollar on the informal market. Suddenly, the state needed far more pesos to buy the same amount of foreign oil. Food and medicine shortages mounted alongside fuel scarcity. The government chose to prioritize tourism infrastructure, building luxury hotels in Havana while the power plants rusted. That gamble failed. Tourists don't want to vacation in a country with blackouts and no air conditioning.
The Shifting Alliances of Havana
Cuba is desperately looking for new lifelines. Russia and Mexico have stepped in with occasional oil shipments, but it isn't enough.
Russia sent several tankers of crude to help ease the crisis, but Moscow expects payment or significant geopolitical concessions. Mexico's state oil company, Pemex, also supplied millions of barrels of crude under the administration of Andrés Manuel López Obrador. However, these shipments are irregular. They represent temporary relief, not a permanent solution.
China has assisted with solar panel installations, but transitioning a nation's entire energy mix takes billions of dollars and decades of work. Cuba doesn't have time. The immediate need is for heavy crude and diesel to run the existing thermoelectric plants.
Navigating the Crisis on the Ground
If you are trying to understand how this impacts business and daily life, look at the private sector. The growth of small and medium-sized private enterprises, known as mipymes, has created a bizarre economic duality.
Private restaurants and stores manage to stay open by buying expensive, black-market gasoline to run portable generators. The noise of small engines echoes through the streets of Havana every evening. But this option is out of reach for the average citizen. A gallon of gas on the black market can cost more than a week's wages for a state worker.
This economic pressure has triggered an unprecedented migration wave. Since 2022, over half a million Cubans have fled to the United States. It is the largest exodus in the island's modern history. Doctors, engineers, and technicians are leaving. The very people needed to fix the power grid are packing their bags.
What Needs to Change
Fixing Cuba's energy crisis requires a multi-pronged approach that addresses both international politics and domestic policy.
First, the United States needs to re-evaluate the State Sponsor of Terrorism designation. Removing this label would allow Cuba to access international banking channels, making it possible to purchase maintenance parts directly and transparently.
Second, Havana must reform its investment priorities. The state must halt luxury tourism construction and divert those funds directly into grid modernization and renewable energy projects.
Third, decentralized solar grids must be fast-tracked. Relying on massive, centralized Soviet-era plants means that one failure darkens an entire province. Smaller, localized solar farms can keep communities running independently when the main grid fails.
The current situation is unsustainable. Without structural economic reform and a easing of financial sanctions, Cuba will continue to drift deeper into the dark.
