Massive power outage strikes San Francisco as system glitch warns of chaotic blackout

A massive power outage struck San Francisco Saturday morning when a routine operation at two substations triggered an unexpected blackout affecting around 9,400 customers of PG&E. Adding to the confusion, a system error falsely notified another 120,000 customers that they had lost power. This glitch highlights vulnerabilities in the power grid's monitoring systems and raises questions about reliability and preparedness for future incidents. The incident underscores the importance of robust infrastructure to prevent both actual and perceived power disruptions.
