ComEd is calling the July 11 storms and subsequent power outages one of the worst on record. 

"It's one of the worst storms we've seen in the last 10 years," a spokesperson said. 

Storms blew through Chicagoland this morning, leaving trees down and power out. At the height of the problem, 765,000 were left in the dark. The northern region was the hardest hit with 298,000 customers affected.

As of 2 p.m., ComEd has restored power to 20,000 customers in the northern region. 278,000 remain without power.

A total of 578,000 are still without power across the entire Chicago area. A company representative said it could take days before everyone has electricity again. 

Noon, July 11

The intense lightning and high force winds that tore through Illinois have left 660,000 people in Northern Illinois without power as of 10 a.m. July 11, according to a Commmonwealth Edison spokesperson.

“In the northern suburbs, which includes Libertyville, we have 298,000 customers out,” according to the ComEd spokesperson.

ComEd says it's still in its damage assessment stages and that it could take “multiple days” to restore power in the area.

“We have 450 crews that are currently working in the field to get customer restored,” according to the ComEd spokesperson.

In addition, ComEd says they may request help from neighboring utilities from other states to restore power in Northern Illinois.

“We are expecting to have quite a bit of assistance on hand to help us,” according to the ComEd spokesperson.
