A crane accidentally took out a power line to the primary Tesla Motors factory Friday morning.
The Fremont, Ca. facility lost power at about 9:35 a.m. ET, a spokeswoman for the electric automaker said. An evacuation alarm sounded, but problems appeared to be limited to the plant, the Fremont Police Department said on Twitter.
"Most non factory employees will work from our Palo Alto or other offices, or from home today," the spokeswoman said in a statement.
Utility Pacific Gas and Electric is evaluating the outage. Tesla did not say if it would affect car production.
