A nationwide power outage occurred in Cuba on September 10, beginning at 9:14 a.m. local time. The cause of the blackout is under investigation by Cuban authorities, and as of 1:00 p.m., there was no information about when electricity would be restored. The U.S. Embassy in Havana has advised U.S. citizens in Cuba or those planning to travel to the country to be aware of the situation and make necessary preparations, as reports indicate cellphone and internet service disruptions.
According to the U.S. Embassy, "Cuba’s electrical grid is increasingly unstable and there have been multiple nationwide power outages since October 18, 2024. 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."
The embassy also noted that while many large businesses, hotels, hospitals, and institutions use generators during blackouts, they may not be able to maintain services if an extended outage continues due to inconsistent fuel supplies.
U.S. citizens are encouraged to monitor updates from Unión Eléctrica (UNE) through its daily bulletins and social media accounts, stay informed via local media outlets, remain in contact with family and friends, and prepare for prolonged outages by keeping devices charged, having flashlights accessible with spare batteries, storing nonperishable food and water supplies, and planning alternative solutions for medical needs dependent on electricity.
For further information or assistance, the U.S. Embassy in Havana provided contact details including a phone number for emergencies and an email address for American Citizen Services.
