Cuba Suffers Persistent Power Outages Amidst 2,000 MW Deficit

Qué pasó

Cuba is experiencing another day of significant power outages, with the national electric system facing deficits close to 2,000 megawatts during peak hours. This situation has been ongoing, affecting daily life across the island.

The energy deficit persisted throughout Wednesday and into Thursday morning. The Union Eléctrica (UNE) reported a maximum outage of 1964 MW on Wednesday night, with projections for Thursday evening anticipating up to 1945 MW of deficit.

Dónde y cuándo

The widespread power cuts are affecting the entire country. The situation was critical on Wednesday, May 20, 2026, and continued into the early hours of Thursday, May 21, 2026. The peak demand hours, particularly at night, see the most severe disruptions.

In the early morning of May 21st, with a demand of 2697 MW, the system was already experiencing a 1370 MW deficit, demonstrating the severity of the ongoing crisis.

Por qué es importante

These continuous and extensive blackouts have a severe impact on millions of Cubans, disrupting essential services like water pumping and affecting overall quality of life and economic activity.

The structural issues within Cuba's electrical system, coupled with fuel shortages and maintenance problems, mean that even minor improvements in generation capacity do not significantly alleviate the daily struggles faced by the population.

Qué dicen las partes

The Union Eléctrica (UNE) is providing daily reports on the energy situation. They indicated a slight projected decrease in the deficit for May 21st but acknowledged the ongoing problem.

While the recent integration of 54 solar photovoltaic parks has increased generation by 3532 MWh and peaked at 530 MW during the day, specialists note this is insufficient to compensate for the system's structural flaws, especially the high demand during non-solar hours.

Averies were reported in units at the Ernesto Guevara, Lidio Ramón Pérez, and Antonio Maceo thermoelectric plants. Other plants in Mariel, Renté, and Nuevitas are undergoing scheduled maintenance, contributing to a total of 470 MW offline.

Qué viene ahora

The outlook for immediate relief remains dim as the combination of breakdowns, maintenance, and fuel deficits creates a significant gap between generation capacity and demand.

Residents and businesses will likely continue to face extensive power interruptions, making planning and daily operations challenging. The contribution from solar energy is positive but does not solve the core issue of nighttime power generation.
