Energy company expects the vast majority of impacted customers to be restored by Sunday afternoon
CHICAGO (July 29, 2023) – After significant thunderstorms and strong winds moved through northern Illinois Friday evening, ComEd crews have restored power to more than 110,000 customers, approximately 90 percent of the nearly 124,000 customers impacted by the storm. The hardest hit areas were in the southern part of our service territory, including Joliet and University Park, and the far western part of our service territory including Dixon, Freeport, and Rockford.
Approximately 14,000 customers remain without power as of noon, Saturday, July 29, while more than 500 ComEd and contractor crews work 24/7 to restore service to all remaining customers as quickly and safely as possible. ComEd expects that the vast majority of remaining customers will be restored by Sunday afternoon, July 30. Localized areas experiencing major damage requiring significant repairs may take longer to restore.
"ComEd crews are hard at work throughout the region to restore power to customers following last night's severe weather," said Dave Perez, senior vice-president of Distribution Operations at ComEd. "We recognize that any outage is frustrating to our customers, and we thank everyone for their patience as we work to safely repair damaged equipment and restore service to our customers as quickly as possible."
With severe weather showing up early and often, and high summer temperatures placing more stress on the electric grid, ComEd has taken steps to ensure reliable energy for the 9 million people it serves in northern Illinois.
ComEd has been investing in power grid upgrades and tree trimming to minimize the impact of storms. Since smart grid upgrades began in 2011, ComEd has avoided more than 19 million power outages — saving more than $3.3 billion in outage-related costs — and has improved overall reliability by more than 80 percent. In 2022, ComEd delivered its best reliability ever and was recognized with the ReliabilityOne Award for having the most resilient power grid in the United States.
