SAN FRANCISCO: A huge electricity outage hit San Francisco on Saturday, leaving 130,000 residents without power and prompting city authorities to ask residents to stay home, according to official and utility provider statements. Large parts of the West Coast tech hub, which has a population of more than 800,000 people, were plunged into darkness with disruptions to public transport and many traffic lights not working on a busy Christmas shopping weekend.

The outage represents roughly one-third of the utility company's customers in the city.
