Cuba’s national electricity grid collapses again, causing a nationwide blackout that leaves millions of people without power. Multiple outlets report that the collapse occurs on Monday, with some describing it as starting around midday or Monday morning. Coverage says most of the country remains without electricity about a day later, with many areas in darkness. Estimates vary slightly, but several reports describe outages affecting nearly the entire island and putting around 9.6 million or roughly 10 million people without power. Some outlets also note that the repeated failures have pushed residents to the limits, citing ongoing frustration and daily disruption, especially during warm weather conditions. Caribbean360 adds that the blackout sparks spontaneous protests, though the reports do not provide detailed triggers beyond the power loss itself. One source says the cause is unknown, and others do not specify a confirmed technical reason for the collapse. Havana Times says the country has experienced multiple total grid collapses in recent years and into 2026, indicating a pattern of repeated breakdowns. Reporting also references ongoing efforts to restore power, without providing a consistent timeline for full recovery.
