Americans traveling to Cuba are being urged to prepare for major disruptions after the country’s electrical grid collapsed, triggering another nationwide blackout and widespread communication outages.
The U.S. Embassy in Havana issued a security alert after Cuba experienced a total power failure at 10:43 p.m. EST on August 2, warning U.S. citizens on the island and those planning to travel that the cause of the collapse and the timeline for restoring electricity remain unknown.
The latest outage marks Cuba’s sixth nationwide electrical grid failure of 2026, including three that occurred in July, underscoring the worsening instability of the island’s aging power system.
U.S. Embassy Advises Travelers To Prepare for Extended Outages
In its alert, the embassy warned that cellphone and internet service have also been disrupted and urged Americans to be prepared for prolonged interruptions to daily life.
Officials advised travelers to:
- Monitor updates from Cuba’s national electric utility, Unión Eléctrica (UNE), and local media.
- Keep mobile phones and portable battery banks fully charged.
- Have flashlights and extra batteries available.
- Stock nonperishable food and drinking water.
- Ensure prescriptions and other medications are available.
- Make contingency plans for medical devices or medications that require electricity or refrigeration.
- Stay in contact with family and friends whenever possible.
The embassy noted that scheduled power cuts occur daily across Cuba, while unscheduled outages have become more frequent, with electricity shortages exceeding 60% of demand.
Sixth Nationwide Blackout Highlights Cuba’s Deepening Energy Crisis
The latest collapse follows multiple nationwide failures earlier this year, including two in March and three in July, along with numerous regional outages.
According to Cuba’s national grid operator, efforts to restore electricity Monday were hampered by thunderstorms, which disrupted generating units that had already been brought back online during restoration efforts.
Authorities have not announced the cause of the latest collapse.
The repeated failures have intensified Cuba’s years-long energy crisis, with the country’s aging electrical infrastructure struggling under persistent fuel shortages.
Extreme Heat Forces Residents To Sleep Outdoors
The recurring blackouts have made daily life increasingly difficult for millions of Cubans, particularly during the Caribbean summer.
On the night of the latest outage, temperatures reached 93 degrees Fahrenheit but felt closer to 106 degrees because of humidity approaching 80%.
With air conditioning unavailable and fans silent, many residents sought relief outdoors. Some spent the night sleeping along Havana’s Malecón waterfront, while others rested on balconies, porches, and sidewalks in an effort to escape the oppressive heat.
Rolling blackouts have also forced many families to adjust their daily routines, cooking meals, washing clothes, charging electronic devices and accessing the internet whenever electricity briefly returns because they never know how long power will remain available.
Fuel Shortages Continue To Strain Cuba’s Electrical Grid
Cuba has faced years of challenges maintaining its electrical system as aging infrastructure and limited fuel supplies have strained power generation.
The latest blackout comes as the island continues to experience fuel shortages that have affected electricity production and transportation. Taxi drivers in Havana have increasingly turned to solar-powered tricycles as fuel becomes harder to obtain, while Cuba has gradually expanded its use of solar energy in an effort to reduce pressure on the grid.
The Cuban government has also approved new measures aimed at attracting private investment into the energy and tourism sectors, including authorizing businesses to distribute fuel wholesale and allowing the country’s first foreign investment venture to import and sell fuel. Officials have acknowledged, however, that those reforms are expected to produce results gradually.
Cuba Travel Restrictions Remain in Effect
Although U.S. law generally prohibits tourism to Cuba, Americans may legally travel under several authorized categories, including family visits, journalism, educational activities, religious programs, humanitarian projects and support for the Cuban people.
The U.S. State Department has previously advised travelers to remain alert while visiting Cuba, warning that prolonged power outages may disrupt communications, transportation and access to essential services.
Americans planning to visit Cuba are encouraged to enroll in the Smart Traveler Enrollment Program (STEP) to receive security alerts and emergency updates from the U.S. government while abroad.
