Cuba reports second nationwide power grid outage in a week

Cuba's aging grid and fuel shortages, worsened by a U.S. oil blockade, triggered the third island-wide blackout in March affecting over 10 million residents, officials said.

  • On March 21, Cuba's National Electric Power System collapsed at 6.32pm, causing a third islandwide blackout this month affecting 10 million people.
  • Aging thermoelectric plants and fuel shortfalls have caused routine outages and rolling blackouts up to 12 hours, with Cuba producing barely 40 per cent of needed fuel and no foreign oil for three months.
  • Authorities said restoration protocols were activated and hospitals postponed thousands of surgeries while ordinary Cubans faced food spoilage, interrupted cooking, and reduced work hours.
  • Amid a diplomatic standoff, the Cuban government blamed an effective U.S. energy blockade and tariffs for worsening fuel shortages, while the U.S. administration defended the executive order of January 29 and cited a 'friendly takeover' threat.
  • Recent outages show Cuba's power system is deteriorating, with one total failure in a week, while Mexico halted shipments and Cuba was excluded from a Russian-oil exemption.
