The power went out around 3:30 p.m. after Xcel says there was a problem with a substation.
The perimeter of the power outage was South Hazel to the west, South Franklin Street to the east, East Evans Avenue to the south and East Alameda Avenue to the north.
Crews were trying to determine the cause of the problem at the substation to restore power.
Six other substations across the area were without power for about 10 minutes, but power at those was also restored.
