Cuba Energy Crisis: 63% of the Island Without Power This Saturday

The energy crisis in Cuba has reached a new boiling point this Saturday, March 7, 2026. According to official reports from the Cuban Electrical Union (UNE), blackouts are expected to simultaneously affect up to 63% of the national territory during peak demand hours.

This massive generation deficit, which exceeds 2,000 megawatts (MW), is caused by a mix of factors paralyzing the National Electric System (SEN). The primary causes include a lack of fuel for floating power plants and generation engines, as well as critical failures at the country’s main thermal power plants.

An Energy Emergency Scenario

The outlook for Cuban families remains grim. In many provinces, electricity service is limited to just 2 or 4 hours a day, making food preservation and daily life nearly impossible. The lack of fuel, exacerbated by state financial and logistical hurdles, has prevented the recently arrived Russian tanker Sea Horse from providing significant relief.

Causes of the current crisis:

• Failures at thermal power plants: Key plants like Antonio Guiteras are operating below capacity or suffering unplanned shutdowns.
• Fuel shortage: Distributed generation is almost entirely stalled due to the lack of diesel and fuel oil.
• Outdated infrastructure: Decades of deferred maintenance have left the system on the verge of total collapse.

Impact on People and the Economy

The prolonged blackouts not only affect citizens’ well-being but also strangle the nation’s fragile economy. Small private businesses (SMEs) face extreme difficulties operating, and the lack of refrigeration puts the limited food supply at risk.

Despite government attempts to implement structural changes to the economic model, a short-term solution for the energy deficit seems increasingly unlikely, as reliance on foreign aid from countries like Mexico and Russia continues to be vital for survival.

Frequently Asked Questions (FAQ)

What is the percentage of electrical outages in Cuba today?

Up to 63% of the country is expected to suffer simultaneous blackouts during peak demand this Saturday, March 7.

Why are there so many blackouts in Cuba now?

The crisis is primarily due to a lack of imported fuel, recurring failures at aging thermal plants, and a long-standing lack of investment in power infrastructure.

Which power plants are currently offline?

Units at Mariel, Santa Cruz del Norte, and Felton are currently facing repairs, while the main plant, Antonio Guiteras, remains unstable.

Are there any short-term solutions for the energy crisis?

While fuel shipments have arrived from Russia and Mexico, the massive scale of the generation deficit requires deep structural repairs that are not expected to be resolved immediately.
