Massive blackout leaves most of Cuba, including Havana, without power

Mar 7th 2026

Cuban officials report a nationwide blackout after the island's biggest plant failed, and they blame constrained fuel access linked to U.S. measures; the outage comes as diplomatic tensions rise after Ecuador expelled Cuba's ambassador and the U.S. announced a Special Forces deployment to Ecuador.

  • Cuban officials and state media say the island's largest power plant unexpectedly went offline, leaving most of the country without electricity.
  • Havana and other major cities were reported without power during the outage, according to Cuban sources.
  • Cuban authorities and state outlets said limited fuel access tied to U.S. measures has hampered efforts to restore power.
  • Ecuador announced it had declared Cuba's ambassador and diplomatic staff persona non grata and expelled them, citing diplomatic reasons.
  • U.S. officials announced a deployment of Special Forces to Ecuador for joint operations, a move that regional politicians said has heightened diplomatic tensions.
