HAVANA, Sept 18 (Reuters) - Cuba's energy grid suffered a total collapse on Friday, the energy ministry said in a post to social media, causing a nationwide blackout on the island of about 9 million people.
Cuba's aging power generation system has been under severe strain from fuel shortages, deteriorating infrastructure and a U.S.-imposed oil blockade. Even when the national grid is online, the island frequently experiences rolling blackouts that leave millions without power.
