Nationwide Blackout Hits Cuba Amid U.S. Sanctions and Power Plant Failures

August 3, 2026

Havana, August 3: A nationwide blackout has once again struck Cuba, according to the National Electric Union. The union announced on social media that the country’s national power system completely shut down at 22:43 local time (02:43 GMT) on Sunday.

As reported by the Xinhua news agency, a partial failure of Cuba’s national electric system had already caused power outages in the western regions on Saturday.

The statement indicated that U.S. sanctions are hindering Cuba’s ability to import fuel and repair its aging power plants. Since October 2024, Cuba has experienced multiple blackouts due to power plant failures, storms, and other reasons.

Earlier on August 1, the National Electric Union reported a partial failure of the national electric system, affecting provinces from Matanzas to Pinar del Río. The blackout occurred at 18:07 local time, attributed to a trip in the transmission lines. Additionally, the partial collapse of the national electric system led to power outages in the western provinces on Saturday.

In a brief statement on social media, the union noted that the failure occurred between Matanzas and Pinar del Río provinces at 18:07 local time, caused by the trip of transmission lines.

In July, a 100-page report from the U.S. State Department accused the Cuban government of playing a leading role in shaping some of America’s most notorious extremist movements and operating espionage and sabotage networks on U.S. soil.

Cuba dismissed the report, claiming it promotes a false narrative aimed at justifying Washington’s long-standing aggressive policies against the island nation.

Cuban President Miguel Díaz-Canel stated in a post on the social media platform X that the report was promoted by one of the most corrupt officials in the current government, who has proven ties to drug traffickers and terrorists in Florida.

Díaz-Canel emphasized that decades of U.S. sanctions, along with the recently imposed fuel ban, are part of a strategy to turn the Cuban people against their revolutionary government.
