SAN DIEGO (AP) - The lights are back on in Arizona and steadily returning to parts of Southern California and Mexico after a power outage affecting millions of people.
By early Friday, energy had been restored to some 930,000 users in the region. That's according to a combined tally provided by officials in Arizona, California and Mexico.
Authorities say the outage was accidentally triggered about 4 p.m. Thursday when an electrical worker removed a piece of monitoring equipment at a power substation in southwest Arizona.
The San Diego area was hit especially hard with power severed to all of San Diego Gas & Electric Co.'s 1.4 million household and business customers, the company said.
