Cuba Power Crisis: Deficit Nears 2,000 MW This March 4

The energy crisis in Cuba has reached critical levels this Wednesday, March 4, 2026. According to reports from the national electric utility (UNE) and independent media, the power generation deficit is hovering near 2,000 MW, meaning more than half of the country remains without electricity simultaneously.

Critical Situation in the National Electric System

The outlook for today is bleak. The availability of the National Electric System (SEN) is insufficient to cover a demand exceeding 3,100 MW. Authorities confirmed that the maximum impact during the evening peak on the previous day reached 1,947 MW, a figure that places the island on the brink of a total service collapse.

Factors Behind the Collapse

Fuel Shortage: Thermoelectric power plants (CTE) are operating with minimum levels of crude and fuel oil.
Technical Breakdowns: Several key units, including blocks at CTE Mariel and CTE Felton, are out of service due to malfunctions or postponed maintenance.
Distributed Generation Deficit: Due to a lack of diesel, the generator sets that should provide support during peak hours cannot operate.

Impact on Havana and Provinces

Although the capital has traditionally been shielded from the most severe cuts, the Havana Electric Company reported that service was interrupted for more than 13 hours and 30 minutes yesterday. In inland provinces such as Holguín, Santiago de Cuba, and Villa Clara, citizens report blackouts lasting up to 18 to 20 hours daily.

This situation paralyzes the national economy, affects food preservation, and worsens the health crisis in hospitals already operating under precarious conditions.

Frequently Asked Questions (FAQ)

What is the current electricity deficit in Cuba?

As of March 4, 2026, the generation deficit is estimated at 1,960 MW, which represents approximately 64% of the national demand left uncovered.

How long do blackouts last in Havana?

In recent days, power cuts in the capital have exceeded 13 consecutive hours, a record high for the city.

Why are there so many blackouts in Cuba now?

The combination of a chronic lack of imported fuel and the critical state of the thermoelectric plants—many over 40 years old and lacking proper maintenance—has led to this collapse.

When will the electricity situation improve?

Authorities have not provided a short-term recovery schedule, linking any improvement to the arrival of oil shipments that have yet to materialize in 2026.
