Police say the evacuation of about 250 people began just before 1 p.m. Friday at The Pavilion apartments in the Wynnfield Heights section of the city following the outage.
Residents were taken to a shelter set up at West Philadelphia High School, and work was to begin Saturday on repairing the problem. Police say some people were taken to a hospital for evaluation.
Fire officials told KYW-TV that all residents had to leave because the electric company had to cut the building's remaining power to restore the rest. Crews used some power to restore one of the building's three elevators to evacuate residents who hadn't left already.
