Cuba Working to Restore Power After Second Nationwide Blackout This Week

Cuba's electrical grid failed completely for the second time in one week, leaving 10 million residents without power after a major plant went offline Saturday evening. Officials began restoration efforts Sunday morning, establishing emergency power circuits for hospitals and essential services while residents cope with ongoing communication blackouts.

Cuban officials launched restoration efforts Sunday morning following the nation’s second complete electrical grid failure within a seven-day period, as ongoing U.S. oil restrictions continue to strain the island’s struggling power infrastructure.

The nationwide blackout began Saturday at 6:32 p.m. local time when a critical power facility in Nuevitas, located in Camaguey province in eastern Cuba, experienced failure and shut down, according to grid operator UNE. This malfunction triggered a domino effect that left approximately 10 million Cuban citizens without electricity.

By early Sunday, Cuba’s energy and mines ministry reported establishing emergency microsystems – compact, isolated electrical circuits – across all provinces to provide power to critical facilities including medical centers, water treatment plants and food distribution networks.

Ministry officials confirmed via social media that two natural gas facilities operated by Energas were operational in Varadero and Boca de Jaruco, while the Santa Cruz oil-burning plant had successfully received electrical service.

As dawn broke Sunday in Havana, residents filled the streets and gathered on stoops, discussing their predicament with neighbors while dealing with insects in the mild morning air beneath clear skies.

“Life doesn’t change. We’re stuck in the same rut,” Havana resident Leoni Alberto stated, explaining he must resort to wood-burning stoves at least twice weekly due to frequent power failures. “It’s absolute madness. There’s no other way around it.”

Mobile phone networks and internet connectivity remained largely unavailable throughout most regions, cutting off communication channels for countless residents.

Cuban Prime Minister Manuel Marrero described the restoration process as occurring under “very complex circumstances.”

Cuba’s electrical infrastructure has remained unstable and on the verge of total failure for months, regularly leaving citizens in darkness for multiple hours daily, and sometimes extended periods, even during relatively stable times.

Saturday’s power failure represents the third significant outage this month, following a March 4 incident when a primary thermoelectric generation facility failed, affecting most of the system. The grid also experienced a complete shutdown Monday for undisclosed reasons.

While Cuba has endured multiple total blackouts in recent years, experiencing two complete nationwide outages within one week represents an unusual occurrence.

Following Washington’s January 3 removal of Venezuelan President Nicolas Maduro, U.S. President Donald Trump implemented measures blocking oil shipments to the Caribbean nation. Venezuela had previously supplied petroleum to its close partner under advantageous agreements.

Trump has since halted Venezuelan oil exports to Cuba and warned other nations of potential punitive trade measures if they provide petroleum to the island.

Cuban leadership has consistently blamed the U.S. trade embargo for economic problems including its outdated electrical system, while Washington points to Cuba’s Soviet-era centralized economy as the source of these deficiencies.
