Cuba’s Fuel and Electricity Crisis: Why Blackouts Are Lasting Up to 22 Hours

Cuba is experiencing one of its most severe energy crises in decades. Officials say the country has exhausted its remaining stocks of diesel and fuel oil, leaving the national power grid unable to meet demand and triggering extremely long daily outages in the capital, Havana .

The shortages have pushed the island’s electricity system into a critical state, sparked street protests, and intensified debate over the causes of the crisis—from international sanctions to declining fuel imports and aging infrastructure.

Cuba’s Fuel Supplies Have Run Dry

Cuba’s energy and mines minister, Vicente de la O Levy, said the country currently has “absolutely no fuel oil” and “absolutely no diesel” available to run many of its power plants . Without those fuels, electricity generation drops sharply because much of Cuba’s grid relies on oil‑fired plants.

Officials say the national energy system now has no reserves of conventional fuel, leaving only limited domestic gas production to support power generation . The shortage comes after months of dwindling imports and irregular shipments from traditional suppliers.

Blackouts Lasting Up to 22 Hours

The immediate result has been a surge in rolling blackouts across the country, with some areas of Havana experiencing power cuts lasting 20–22 hours a day . These outages are among the worst seen in the capital in decades .

Experts and officials warn that the grid has become increasingly unstable as fuel shortages prevent generators from operating normally . With electricity production falling far below demand, authorities have been forced to ration power throughout the island.

Protests Erupt in Havana

The prolonged outages have triggered public demonstrations across parts of Havana, where residents have taken to the streets demanding electricity and basic services .

Reports describe crowds blocking roads, banging pots, and chanting slogans during the protests as frustration grows over the worsening economic situation and frequent power cuts .

These demonstrations represent some of the most visible public unrest tied directly to the country’s energy shortages.

Cuba Blames U.S. Sanctions and Oil Restrictions

Cuban officials argue that the crisis has been intensified by U.S. policies aimed at restricting fuel supplies to the island. Havana says sanctions and pressure on shipping companies have discouraged or prevented oil deliveries that the country depends on .

International organizations have also noted that measures taken by Washington to block or discourage oil shipments have contributed to worsening shortages, though the exact degree of impact remains debated .

Cuba relies heavily on imported oil for electricity generation, making it particularly vulnerable when shipments decline or become politically constrained.

A Growing Humanitarian Concern

The electricity shortages are affecting far more than household lighting. Across the island, power outages are disrupting key public systems, including:

• Water pumping and distribution
• Refrigeration for food and medicines
• Hospital and healthcare services
• Public transportation
• Schools and other public institutions

Humanitarian agencies warn that the energy crisis is compounding existing shortages of food, fuel, and medicine . Earlier in 2026, the United Nations warned that Cuba faced the risk of a humanitarian “collapse” if energy supplies continued to deteriorate .

Why the Crisis Is So Severe

Several factors appear to be converging at once:

• Heavy dependence on imported oil for electricity generation
• Declining or irregular fuel shipments from foreign suppliers
• Restrictions affecting oil deliveries to the island
• Aging power infrastructure that struggles during fuel shortages

Because the grid relies on fuel‑powered plants, even a shortfall in oil or diesel can rapidly translate into large‑scale blackouts.

What Happens Next

For now, Cuba is trying to stabilize its electricity system while seeking additional fuel shipments and international support. However, relief depends largely on restoring reliable fuel supplies and repairing a strained power system.

Until those conditions improve, Cuba’s power crisis is likely to remain a central challenge for the country’s economy, daily life, and political stability.
