HAVANA, Cuba — Cuban energy officials announced significant advancements on Thursday in efforts to restore electricity across the nation following a widespread blackout that plunged approximately two-thirds of the country into darkness. The national grid, which experienced a catastrophic failure on Wednesday, has now been successfully reconnected nationwide, according to an official statement from the Ministry of Energy.
The ministry confirmed that reconnection of the national electrical system was achieved at 5:01 AM local time Thursday, with power generation units being progressively brought back online to facilitate the gradual return of electricity to households and businesses. On-the-ground observations in Havana confirmed that several districts within the capital had already regained electrical service by Thursday morning.
This incident highlights the profound challenges facing Cuba’s aging power infrastructure, which has deteriorated to a state of chronic dysfunction. Many regions across the island regularly endure daily power interruptions lasting up to 20 hours, exacerbated by severe fuel shortages that cripple power generation capabilities.
The current energy crisis unfolds during a period of heightened geopolitical tension for the Caribbean nation of 9.6 million people. The situation has deteriorated significantly since January 3, when the United States moved to oust Venezuelan leader Nicolás Maduro, who had been supplying approximately half of Cuba’s fuel requirements.
Following Maduro’s political crisis, Washington initially imposed stringent oil embargo measures against Cuba before subsequently moderating these restrictions. This policy shift came amid concerns raised by neighboring Caribbean nations warning that extreme sanctions could precipitate total economic collapse and inflict disproportionate suffering on civilian populations. Despite these modifications, the Trump administration maintained substantial blockade measures, leaving oil shipments from Caracas to Havana in a state of prolonged uncertainty.
