Security Alert – U.S. Embassy Havana, Cuba (March 4, 2026)

March 4, 2026
 

 

Location: Western Cuba

Event: Power Outage to Include Havana

At 12:41 p.m. local time, there was a disconnection of the national electrical grid resulting in a complete power outage from Camagüey to Pinar del Río, which includes the Havana metropolitan area.  The disconnection was due to the unexpected shutdown of the Antonio Guiteras Thermoelectric Plant per Cuban regime authorities.  There is no information about when power will be restored to the western Cuba.

Cuba’s national electrical grid is increasingly unstable and prolonged scheduled and unscheduled power outages are a daily occurrence across the country to include Havana.  Outages affect water supply, lighting, refrigeration, and communications.  Take precautions by conserving fuel, water, food, and mobile phone charge, and be prepared for significant disruption.

Actions to take:

  • Review daily updates published by UNE (Unión Eléctrica)    and follow UNE’s social media accounts.
  • Monitor Radio Reloj 101.5 FM and local media for updates.
  • Stay in touch with family and friends.
  • Prepare for prolonged power outages by:
  • Keeping mobile phones and portable battery banks charged
  • Having flashlights and spare batteries in a location easy to access
  • Stocking up on nonperishable food and water
  • Preparing for alternative methods of meeting your medical needs (medical devices requiring power, medicines requiring refrigeration, etc.)
