“Cuba’s power grid collapsed Saturday leaving the country without electricity for a third time in March as the communist government battles with a decaying infrastructure and a U.S.-imposed oil blockade. The Cuban Electric Union, which reports to the Ministry of Energy and Mines, announced a total blackout across the island without initially giving a cause for the outage. The union later said the blackout was caused by an unexpected failure of a generating unit at the Nuevitas thermoelectric plant in Camagüey province.” (03/22/26)
