Electricity restored to almost all affected regions as investigation under way into how outage occurred

Power has been restored to most of Chile’s 19 million people after the country’s most disruptive blackout in 15 years, the government said, as authorities lifted a strict curfew imposed when the outage left 98% of the population without electricity.

Chilean interior minister Carolina Tohá said on Wednesday that electricity had largely returned to Chile’s 14 afflicted regions, although 220,000 residents remained without power.

State of emergency and overnight curfew declared after blackout strands commuters and knocks out traffic lights

Authorities in Chile have declared a state of emergency and overnight curfew after a sweeping blackout stranded commuters, knocked out traffic lights, paralyzed countless businesses and left millions of people in the South American country without electricity.

The National Electrical Coordinator, Chile’s grid operator, said a disruption had occurred in a high-voltage transmission line that carries power from the Atacama Desert of northern Chile to the capital of Santiago in the country’s central valley.
