cuba power outage havana left millions without electricity on Wednesday after an unexpected shutdown at the Antonio Guiteras thermoelectric plant, authorities said. UNE, the national electricity company, said the blackout affected roughly two-thirds of the island from Camaguey to Pinar del Rio, including the capital. The outage compounds chronic fuel shortages and a tightening US embargo that officials and charities link to disrupted fuel deliveries and suspended flights.
Cuba Power Outage Havana: Expanding details
The failure at the Antonio Guiteras thermoelectric facility, about 100km east of Havana, triggered a wide collapse of generation that left swathes of the west and centre of the island in darkness. UNE described the shutdown as “unexpected” and said crews were working to restore services; one affected plant was later reported up and running as teams began reconnecting parts of the national grid. The outage stretched from the central province of Camaguey to the western province of Pinar del Rio and included Havana, with the western region hit for a second time in the past three months.
Cuba’s electricity system faces compounding pressures: crumbling infrastructure and chronic fuel shortages. Aviation fuel shortfalls have forced several carriers to suspend services to Havana, and charities and officials warn the squeeze on fuel has produced mounting humanitarian strains. Power cuts in recent episodes have at times lasted up to 18 hours a day and have affected hospital emergency wards, dialysis patients and water-pumping stations.
Immediate reactions and on-the-ground voices
Manuel Marrero Cruz, Prime Minister of Cuba, wrote that he trusted in the experience and effort of electrical workers to resolve the situation in the shortest possible time, and met with the energy minister to specify next steps. Vicente de la O Levy, Energy and Mines Minister, wrote that the government was working to restore the National Electric System amid a complex energy situation and that critical infrastructure was being prioritized for power restoration.
UNE, the national electricity company, has mobilized crews across regions while local utilities began phased reconnections where the system allowed. Hospital administrators and emergency teams were among those prioritized as grid sections were brought back online.
On the streets, residents described the immediate disruption. Odalis Sánchez, Havana resident, said she was stranded as buses were not running due to fuel shortages and that without power daily life and access to food and transport had ground to a halt. Ernesto Couto Martínez, a local resident, said Cubans must confront the outage with resilience and continue to press on despite the blockade-related pressures cited by officials.
What’s next
Authorities say restoration will proceed gradually and will be tied to the condition of the national grid and available fuel supplies; crews are prioritizing hospitals, clinics and essential services while attempting to reconnect distribution circuits. The latest cuba power outage havana underscores a broader energy fragility tied to fuel availability, and officials and relief groups will be watching supplies and grid stability closely as reconnection efforts continue. Expect staged restorations over the coming days and further government updates on progress and prioritization of critical infrastructure.
