ComEd Restores Power to More Than 95 Percent of Customers Affected by Three Waves of Severe Thunderstorms

2,500 crew members continue work, focusing on hardest hit areas

CHICAGO – (August 12, 2021) – ComEd has restored power to more than 341,000 customers or more than 95 percent of the customers impacted by three severe thunderstorms that swept through northern Illinois on Tuesday night and on Wednesday morning and evening. The storms brought strong wind gusts of 35 to 60 miles per hour that downed trees, branches and powerlines throughout the region.

More than 2,500 ComEd workers and contractors continue to work around the clock to restore power to remaining 11,000 customers quickly and safely. Additionally, more than 607 mutual assistance workers have arrived from Alabama, Delaware, Iowa, Kansas, New York, and Ohio to support the restoration effort. The hardest hit communities include Crystal Lake, Elgin, Libertyville, Mount Prospect and Skokie. ComEd expects all remaining outages to be restored by late afternoon on Friday, August 13. Additional storms are forecasted this evening and could impact restoration work.

"ComEd crews are focused on restoring power to every customer as quickly and safely as possible," said Terry Donnelly, president and COO of ComEd.
