Cuba's power grid collapses repeatedly as US oil blockade cuts fuel supply

Built World

Managing emergency grid restoration after each collapse

Cuba's national power grid collapsed for the fourth time in March on March 21, leaving more than 10 million people without electricity. The failure at the Nuevitas thermoelectric plant in Camagüey province triggered a cascading collapse across the entire system, which was restored by March 23. The island has not received an oil shipment from any foreign supplier in over 90 days—since late December 2025—after the United States imposed diplomatic pressure and tariffs on countries selling oil to Cuba. Cuba produces only 40 percent of the fuel it needs domestically, leaving the aging Soviet-era grid operating on fumes as thermoelectric plants fail repeatedly.
