Cuba Suffers Nationwide Blackout as Power Grid Collapses Again

other · 2026-08-03

Cuba's national power grid failed on Sunday, causing another nationwide blackout, according to a social media post by state utility UNE. The sudden loss of electricity plunged Havana and the rest of the country into darkness, with residents sitting outside to escape the summer heat groaning audibly as lights went out. The blackout is the latest in a series of total collapses, following an outage just 24 hours earlier that darkened the entire western region. The recurring power cuts are attributed to ageing infrastructure, severe fuel shortages, and the US energy embargo, which has halted regular fuel deliveries to power stations. Each outage disrupts daily life, cutting off water supplies and halting ceiling fans. UNE reported a 'total disconnection' of the national electricity system, affecting millions of people across the island.
