Cuba’s power grid collapsed Friday night, triggering a nationwide power outage and plunging its more than 10 million people into darkness.

Cuba's eight thermal power plants, nearly all of which came online in the 1980s or 1990s, suffer routine failures.

The grid failure follows a string of nationwide blackouts late last year that plunged Cuba's frail and antiquated power generation system into near-total disarray, stressed by fuel shortages, natural disaster and economic crisis.
