HAVANA—Cuba suffered a massive power outage Friday night affecting Havana and the country’s provinces that left millions in the dark.

Cuba’s Ministry of Energy and Mines said at around 8:15 p.m. local time an outage at the Diezmero substation on the outskirts of Havana had caused “a significant loss of generation in western Cuba and, with it, the failure of the National Electric System.”
