More than half of Cuba faces a widespread blackout: they are in the dark in Havana

TL;DR

  • Two-thirds of Cuba, including Havana, experienced a total blackout on March 4, 2026, due to a national grid collapse.
  • The incident originated from a critical failure in the Antonio Guiteras power plant's boiler.
  • This blackout affected ten out of fifteen provinces and follows five general power outages since late 2024.
  • Citizens face scheduled power cuts exceeding 15 hours in Havana and over a day in other provinces.
  • Economists attribute the instability to a chronic lack of state investment, while the government cites US sanctions.
  • US sanctions, particularly the halt of oil shipments from Venezuela since January 9, have severely impacted Cuba's energy sector.
  • Extreme austerity measures, including gasoline rationing and suspension of diesel sales, have been implemented.
  • Reduced hospital services are also a consequence of the ongoing energy crisis.
  • The government views the recent expulsion of the Cuban diplomatic mission from Ecuador as an unfriendly act potentially linked to increased US pressure.
