Cuba’s grid fails for sixth time this year as US oil blockade deepens energy crisis
Cuba suffered its sixth major power grid collapse this year on September 18, 2026, leaving millions without electricity. The outage, triggered by transmission faults and poor weather in western Cuba, cascaded island-wide. Restoration is slow, with only 5% of Havana’s users receiving power by dusk. The crisis is exacerbated by a US-imposed oil blockade that has cut fuel imports to near zero, leaving aging infrastructure without maintenance or fuel.
