Cuba experienced an island‑wide blackout on July 6, leaving approximately ten million people without electricity, according to multiple sources. It was the third nationwide blackout this year, and officials said the cause was under investigation.

The outage was linked to an aging power grid and fuel shortages, and the Cuban government blamed U.S. sanctions or an oil blockade for limiting fuel imports.

Fox News reported that millions of people were left without electricity. TASS reported that a thermal power‑plant accident caused massive power outages and noted that the Felton‑1 power unit generates 50 MW and increases the load.

The Hindu reported that President Miguel Díaz‑Canel accused the United States of trying to incite social unrest by strangling Cuba's fuel supply. The Straits Times reported that the blackout was the eighth on the island since late 2024, that there was a total disconnection from the national electricity generation system, and that the Capitol dome lit up during a power outage in Havana on July 2. It also noted that Cuba’s population is about 9.6 million people.
