Cuba Facing Slow Power Grid Recovery After Seventh National...

Qué pasó

Cuba was plunged into darkness once again on Saturday, March 22, 2026, following the seventh collapse of the National Electroenergetic System (SEN) in less than 18 months. The massive blackout began at 18:38 local time when a failure at Unit No. 6 of the 10 de Octubre thermoelectric plant in Nuevitas, Camagüey, triggered a cascade effect across other operating plants.

This event highlights the ongoing and severe energy crisis gripping the island nation.

Dónde y cuándo

The blackout occurred on Saturday evening across the entire island. The primary failure point was identified at the 10 de Octubre thermoelectric plant in Nuevitas, Camagüey. The impact was widespread, leaving most of the island without electricity.

In Havana, over 90% of the capital remained without power. In Villa Clara, only a quarter of the supply had been recovered. Provinces from Pinar del Río to Guantánamo are relying on small, isolated power grids for essential services.

Por qué es importante

This recurring national blackout signifies a critical failure in Cuba's energy infrastructure, impacting daily life, essential services, and the national economy. The inability to maintain a stable power supply creates uncertainty and hardship for the population.

The gradual, regional recovery plan indicates that a swift return to normalcy is unlikely, suggesting prolonged instability and potential future disruptions.

Qué dicen las partes

Energy sector authorities have warned that the recovery will be gradual. They are working to establish regional micro-systems to reconnect the country in stages, prioritizing western and central regions before addressing the east.

Lázaro Guerra Hernández, an energy official, stated that two relatively stable micro-systems are already functioning. Minister of Energy and Mines, Vicente de la O Levy, indicated that efforts are focused on strengthening western and central micro-systems to eventually unify the SEN.

Qué viene ahora

The focus is on gradually unifying the national grid by stabilizing and expanding these regional micro-systems. This approach aims to prevent future large-scale collapses while restoring power to affected areas.

The process is expected to be slow, with the eastern part of the country being the last to be reconnected. The success of these micro-systems will be crucial for the island's energy stability in the near future.
