On December 24, 2025, a day when Cubans hoped for at least a brief respite due to the Christmas holiday, the nation once again faced power outages throughout the entire day. The Union Electrica (UNE) reported a peak impact of 2,015 megawatts (MW) at 6:30 p.m., exceeding official predictions.
The primary reason for the energy collapse, according to the official statement, was the failure to bring Unit 6 of the Mariel Thermoelectric Power Plant (CTE) online, which had been anticipated to partially reduce the deficit.
Additionally, simultaneous breakdowns occurred in units at the Antonio Maceo CTE in Santiago de Cuba, the Mariel CTE, and the Felton CTE in Holguín. Several other plants were undergoing maintenance or were out of service due to shortages of fuel and lubricants.
Over the past five years, power outages have become a chronic issue, escalating in the latter half of 2025. This Christmas Eve, they overshadowed festive celebrations across the country.
Cuba's energy crisis starkly highlights the government's inability to provide a stable electricity service, even during symbolic and significant dates for the public.
