A power outage left hundreds of homes and businesses without electrical service for hours early Tuesday in parts of Kearny Mesa, Mission Valley and Tierrasanta.
The blackout, which began about 2:30 a.m., initially left roughly 850 San Diego Gas & Electric customers without power, the utility reported.
Within three hours, repair personnel had that number down to 290, according to SDG&E public affairs.
As of 11 a.m., power had been restored to all the affected addresses, the utility company reported.
The cause of the outage was under investigation, SDG&E officials said.
