Cuba’s national power grid comes back on after 10 million people were plunged into darkness overnight.
Published on 18 March 2026
Cuba has reconnected its power grid and brought its largest oil-fired power plant online, energy officials said, ending a nationwide blackout that lasted more than 29 hours amid a United States move to cut off the island’s energy supply.
The Caribbean island’s national power grid was fully back online by 6:11 pm (22:11 GMT) on Tuesday, after 10 million people in the country were plunged into darkness overnight. However, due to insufficient power generation, power shortage may continue, officials said.
