HAVANA, Cuba — Cuba's national electric grid suffered another nationwide collapse on Tuesday, marking the third major blackout in just nine days and intensifying the country's worsening energy crisis that has left millions of residents struggling without reliable electricity.
The Cuban Ministry of Energy and Mines confirmed that the National Electric Power System experienced a "total disconnection," plunging much of the island of approximately 10 million people into darkness. The latest outage comes as the country continues to grapple with aging infrastructure, severe fuel shortages, and mounting economic challenges.
Authorities said the blackout occurred after a failure in the national power system, though restoration efforts began immediately. Engineers have been working to rebuild the electrical network by creating isolated "micro-islands" of electricity that can gradually be reconnected into the national grid, a process used during previous nationwide outages.
In Havana, the capital city, traffic lights went dark, businesses closed their doors, and neighborhoods were left relying on backup generators where available. Residents sought relief from the summer heat while waiting for electricity to return, as fans, air conditioners, and refrigeration systems stopped functioning.
The repeated grid failures have become increasingly common in Cuba, where much of the electricity infrastructure is decades old and has suffered from years of underinvestment. The country has also struggled to secure enough fuel to operate its thermoelectric power plants, leading to frequent scheduled outages that have now escalated into nationwide blackouts.
Government officials have attributed the worsening crisis in part to fuel shortages linked to disruptions in oil imports. According to Reuters, Cuba's energy supply has been significantly affected after its primary oil supplier, Venezuela, experienced political upheaval earlier this year, while additional pressure led Mexico to halt oil shipments to the island.
The prolonged electricity shortages have had a widespread impact on daily life. Hospitals, water pumping stations, food storage facilities, and communication services have all faced operational challenges during recent outages, although authorities have prioritized restoring power to essential services whenever possible.
Residents have expressed growing frustration over the recurring blackouts, with some communities holding small nighttime demonstrations demanding improvements to the country's electricity supply. Many families have struggled to preserve food, access clean water, and cope with extreme heat as outages have become more frequent.
Cuba has experienced several nationwide grid collapses in 2026 alone, underscoring the fragility of its electricity system. Experts warn that without significant investment in power generation, transmission infrastructure, and fuel supplies, similar large-scale outages are likely to continue.
Energy officials said restoration work remains ongoing and pledged to return electricity to customers as quickly as conditions allow. However, no timeline has been provided for a full recovery of the national power system.
