On 10 September, Cuba suffered its fifth nationwide blackout in less than a year, leaving 10 million people without power. Even before the grid collapse, most residents were enduring daily blackouts of up to 16 hours. The outage, tied to a shutdown at the Antonio Guiteras plant, comes amid the country’s worst economic crisis in decades, marked by fuel, food, and other shortages. U.S. sanctions have restricted access to foreign currency needed for fuel and repairs. The recent installation of 30 solar parks with Chinese funding has not yet eased the crisis, while recurring blackouts have sparked anti-government protests.
