Nationwide blackout hits Cuba again after total collapse of national power grid

Cuba has experienced another nationwide power outage after the country's electricity grid suffered a total system collapse, leaving millions of residents without electricity, including in the capital, Havana.

State-owned utility Unión Eléctrica (UNE) reported that the national electricity system underwent a complete disconnection late Sunday night, triggering the sixth nationwide blackout recorded on the island in 2026.

The Ministry of Energy and Mines confirmed that the outage began at 10:43 p.m. local time and said emergency restoration protocols had been activated to progressively restore electricity across the country.

Authorities launch emergency recovery efforts

Energy officials announced that technical teams immediately began implementing established procedures to reconnect the national grid.

The restoration process is expected to proceed in stages, as engineers gradually restart power generation units and reconnect transmission networks while seeking to maintain grid stability.

Authorities have not yet indicated how long the recovery operation is expected to take or identified the immediate cause of the latest collapse.

Aging infrastructure and fuel shortages strain electricity system

Cuba has endured repeated electricity disruptions in recent years as its power sector struggles with aging infrastructure and limited fuel supplies.

Much of the country's electricity is generated by seven thermoelectric power plants, many of which have been operating for more than four decades and require extensive maintenance.

Frequent equipment failures, combined with fuel shortages, have reduced generation capacity and increased the likelihood of widespread outages, particularly during periods of high demand.

Energy crisis continues amid economic challenges

The latest blackout comes as Cuba continues to face a prolonged economic crisis that has affected energy production, public services and industrial activity.

Government officials have also pointed to tighter fuel supplies following US measures affecting oil shipments to the island, arguing that these restrictions have complicated efforts to secure the diesel and other fuels needed to operate both power stations and backup generators.

The recurring nationwide outages underscore the depth of Cuba's energy challenges and the urgent need for investment in electricity infrastructure to improve the reliability of the national power system.
