HAVANA, Cuba – Cuban energy officials confirmed on Thursday that electrical service had been largely restored following a massive nationwide blackout that plunged significant portions of the country into darkness. The widespread outage, which began Wednesday afternoon, affected approximately two-thirds of the Caribbean nation, including the capital city of Havana.
The Ministry of Energy reported that by late Thursday afternoon, the national grid had been successfully reconnected with approximately 80% of households in Havana regaining power. The initial trigger for the catastrophic failure was identified as a technical breakdown at the Antonio Guiteras thermoelectric plant, Cuba’s largest power generation facility, located in the central-western region.
However, authorities emphasized that the root cause extends beyond mechanical failure to systemic vulnerabilities within Cuba’s energy infrastructure. The fundamental issue stems from critical fuel shortages that have crippled the country’s ability to maintain backup generator support for the national grid. This scarcity directly results from stringent United States restrictions on oil shipments to the island nation.
Cuba’s electrical generation system has deteriorated significantly, with regular daily outages lasting up to 20 hours in some regions becoming commonplace. The current crisis affects all 9.6 million residents and occurs amidst heightened geopolitical tensions following the United States’ diplomatic recognition of Juan Guaidó as Venezuela’s legitimate leader on January 3, effectively ousting Nicolás Maduro.
This political shift has proven particularly consequential for Cuba, as Maduro’s administration previously supplied approximately half of Cuba’s fuel imports. Although Washington initially imposed a comprehensive oil embargo following Maduro’s departure, subsequent modifications eased restrictions after neighboring Caribbean nations warned of potential economic collapse and humanitarian consequences.
Despite these adjustments, the Trump administration maintained substantial pressure through various blockade measures, leaving oil shipments from Caracas to Havana in operational limbo. The complete cessation of oil imports since January 9 has forced airlines to reduce services to the island and exacerbated Cuba’s prolonged economic difficulties.
