ComEd was also on the scene. A ComEd spokesperson said a fire in a manhole damaged equipment, causing 3,500 customers to lose power.
Power has been restored to roughly 3,000 of those customers, using generators, according to the utility.
The other 500 customers are expected to have their power restored Thursday night by 11 p.m.
An investigation into the cause of the fire is underway.
