SAN DIEGO (CBS/AP) – An employee at a power substation in southwest Arizona likely caused a massive outage that left more than 2 million people without electricity across the Southwest and northern Mexico, and forced the cancellation of some Bay Area flights.
Most of San Diego lost power, as well as cities south of the border and about 56,000 people throughout Yuma and the surrounding areas.
Mineta San Jose International and Oakland International each reported that two flights to San Diego had been cancelled. San Francisco International reported one canceled San Diego flight. The majority of the canceled flights were Southwest Airlines routes.
Power officials in Arizona said the employee was carrying out a procedure at a substation in North Gila northeast of Yuma. They didn’t immediately explain the procedure.
Authorities said the outage should have been limited to the Yuma area. They were investigating why it wasn’t contained.
Arizona Power Services President and CEO Don Robinson said they are working to restore power as soon as possible.
