HAVANA—Cuba had restored power to nearly half of the capital Havana by Sunday afternoon, officials said, less than 24 hours after the national grid collapsed for the second time in a week amid a U.S. oil blockade that has dealt a major blow to the island’s already ailing energy infrastructure.
The grid failed Saturday evening at 6:32 p.m. after a major power plant in Nuevitas, in eastern Cuba’s Camaguey province, went offline, grid operator UNE said, causing a cascade effect that knocked out power to the nation’s approximately 10 million people.
