Power restored to most Center City PECO customers

Update: Power was restored by 7:30 p.m. to nearly all those affected by the outage in Center City, a PECO spokesman said. PECO was bringing in generators Tuesday night to service the three to four households whose power remained out. Crews were still working to determine what caused the outage, the spokesman said. 

Original story: An estimated 4,000 Center City residents were without power Tuesday afternoon as PECO crews worked to repair underground equipment in two locations. 

PECO shortly after 3:15 p.m. received reports of underground equipment malfunctions near 13th and Spruce streets and 15th and Waverly streets, a spokeswoman for the electrical company said. About 4,000 people living in surrounding areas remained without power an hour later.

It was not immediately clear exactly what caused the equipment to malfunction or when power might be restored to those affected. PECO crews were in the process of re-routing power Tuesday evening in a bid to restore service to as many customers as possible while continuing to investigate the outage's cause.
