In July 2024, ComEd faced one of the most destructive weather events in its history—a record-breaking “Ring of Fire” storm that unleashed 43 tornadoes, torrential rain, and more than 22,000 lightning strikes across northern Illinois. Despite catastrophic damage, ComEd’s emergency preparedness, planning, and execution kept customers, workers, and communities safe. Join Caralyn Zloch, Senior Emergency Preparedness Specialist at ComEd, as she details how the utility leveraged its Emergency Response Organization, coordinated with local and state agencies to reopen I-55, managed base camps across multiple cities, and overcame simultaneous challenges — from mutual aid deployments to a global IT outage — to deliver one of the industry’s most effective large-scale restorations.
