Cuba power partially restored, says grid operator

March 17 (Reuters) - Power was restored in the western and eastern central regions of Cuba on Tuesday as some power plants reconnected to the grid, Cuba's grid operator UNE said on social media.

Cuba's national electric grid had collapsed on Monday, leaving about 10 million people without power amid a U.S.-imposed oil blockade that has crippled the island's already obsolete generation system.

UNE said that the Diez de Octubre and Carlos Manuel de Cespedes power stations were back online, adding that the western and eastern central systems had been reconnected to the island's grid.
