"Around 7 p.m., I was watching Family Feud and the lights went out," said Miss Thomas. "I came outside and everything was out. I call my neighbor- 'Your lights out? My lights out.'"
Chopper 6 was up above Kensington, where you could see big areas of dark after more than 1,500 customers in the area lost power.
"My phone was running low so I had to come to my car to charge my phone," Thomas added.
Around 7:15 p.m., the fire department was called for multiple transformer explosions. When they arrived, they found a transformer and wires down at Rorer and East Westmoreland streets.
PECO's emergency teams responded and some power came back online, but others remained in the dark throughout the night.

Some centers have daytime hours, others have nighttime hours, and three are open 24/7.
One woman said she came to a center to keep warm or else would have had to find someplace else to go.
"I might go to the library or supermarket, or just someplace to keep warm," Rose Bell told Action News.
"I would like to encourage everyone to use these centers. Use them if you don't have a place to stay -- if you don't have heat in your home," said Jamie Gauthier.
