Cuba has plunged into a nationwide blackout following the failure of the Antonio Guiteras power plant, leaving millions without electricity and prompting the government to implement emergency measures, including shutting down non-essential workplaces and cancelling school classes. Prime Minister Manuel Marrero cited a combination of increased demand, outdated infrastructure, and fuel shortages as key contributors to the crisis, which experts have labeled the worst in the nation's history. The blackout, which began late Thursday, has been exacerbated by the impacts of Hurricane Milton, hampering fuel delivery to power plants. Authorities are considering changes to electricity rates for small and medium-sized businesses, which have surged since their authorization in 2021. The ongoing power outages have left many Cubans facing severe shortages of basic necessities, leading to a record exodus from the island. Government officials have promised to address the energy crisis with the expectation of improved power generation in the coming days.
