Cuba suffered another nationwide power outage on Tuesday after its national electricity grid collapsed, leaving an estimated 10 million people without electricity. The incident marks the country's third island-wide blackout in less than 10 days and the fifth nationwide blackout recorded in 2026.
According to Cuba's state-run electricity company (UNE), the outage began around 11:00 a.m. local time when the entire national grid unexpectedly went offline. The Ministry of Energy and Mines confirmed the incident, describing it as a "total disconnection" of the country's electrical system.
The latest blackout comes amid Cuba's worst economic crisis in decades, with severe fuel shortages and an ageing electricity infrastructure placing enormous strain on the power network. Much of the country's electricity system dates back to the 1960s and 1980s, making it increasingly vulnerable to major failures.
Cuban authorities blame the crisis on a United States oil blockade, which they say has sharply reduced fuel supplies needed to operate power plants. The US government, however, argues that Cuba's long-standing infrastructure problems and government policies are responsible for the repeated outages.
The prolonged power cuts have triggered growing public frustration, with residents in parts of Havana staging protests during previous blackouts by banging pots and pans and demanding the restoration of electricity. In earlier outages this month, it took more than 24 hours to fully restore power across the island.
Officials are continuing efforts to reconnect the national grid, but no official timeline has been announced for the complete restoration of electricity.
