Location:  Cuba

Event: As of 22:43 EST on August 2, Cuba experienced a total power failure due to a collapse of Cuba’s electrical grid. According to Cuban regime media, the reason for the collapse and the timeline to restore power is unknown. All U.S. citizens in Cuba or planning to travel to Cuba should be aware and plan accordingly. There are reports of cellphone and internet outages.

Cuba’s electrical grid is increasingly unstable, and this is the 6th total grid failure of 2026 with three occurring in July 2026 alone. The electrical system remains vulnerable and additional regular outages have been occurring more frequently and for longer periods. Scheduled power cuts occur daily, and unscheduled outages persist throughout Cuba with daily deficits of over 60%.
