Cuba experienced a total blackout for the second time this week

Cuba’s national power grid went completely dark on the evening of March 21, 2026, leaving more than 10 million people without power.

 According to the Ministry of Energy, the outage was caused by a critical power shortage, which reached 1.7 gigawatts during peak hours, CNN reports. The country’s authorities have already activated emergency protocols to restore the grid, but the situation remains difficult due to limited resources.

The massive crisis deepened after the U.S. began blocking fuel shipments from Venezuela, which, combined with a shortage of oil from Mexico, has effectively paralyzed the island’s vital functions. Due to the lack of electricity in Cuba, the tourism industry has ground to a halt, hospitals and schools have been disrupted, and farmers cannot deliver their produce to markets. The situation on the island is escalating against the backdrop of a global standoff, where U.S. interests clash with the positions of Russia’s allies in the region. Efforts to restore power are currently underway, but the timeline for stabilizing the system remains unknown.

As a reminder, Cuba restored its power grid after a massive blackout on March 17.

Trump also confirmed the U.S. intention to intervene in Cuba.
