Who Do I Call to Report a Power Outage in Illinois?
Call your electric delivery utility's outage hotline — not your electricity supplier. Illinois is a deregulated electricity market, meaning you can choose who supplies your power, but your local delivery utility is responsible for the wires, outage response, and restoration. If you don't know your utility, check your electric bill — the delivery charges section lists your utility name.

About This Data
This tracker aggregates real-time outage data from 10 electric utilities operating in Illinois. ComEd, a subsidiary of Exelon, is the largest — delivering electricity to approximately 4 million customers across northern Illinois, from Chicago and its suburbs to Rockford and Kankakee. Ameren Illinois serves about 1.2 million customers in central and southern Illinois, covering Springfield, Peoria, Champaign, and the Metro East area. Several rural electric cooperatives and municipal utilities round out our coverage.
Illinois is a deregulated electricity market — residential and business customers can shop for their generation supplier, but the delivery utility maintains the physical grid and handles outage restoration. ComEd's territory falls within the PJM Interconnection, while Ameren Illinois operates within MISO (Midcontinent Independent System Operator). The Illinois Commerce Commission (ICC) oversees both delivery utilities. County-level outage assignments use FIPS codes from Census Bureau county boundary data.

How does the Illinois power grid work?
Illinois operates a deregulated electricity market where customers can choose their generation supplier while the local delivery utility maintains the grid. ComEd, a subsidiary of Exelon, delivers power to roughly 4 million customers across northern Illinois including Chicago, the suburbs, and Rockford. Ameren Illinois serves about 1.2 million customers in central and southern Illinois including Springfield, Peoria, and Champaign. The grid operates within the PJM Interconnection (ComEd territory) and MISO (Ameren territory). The Illinois Commerce Commission (ICC) regulates utility operations and rates.
What causes power outages in Illinois?
Illinois faces outage threats from severe thunderstorms and derechos in summer, ice storms in winter, and tornadoes during spring and fall. The state's flat terrain exposes power lines to high winds across open prairies, while dense urban tree canopy in the Chicago suburbs leads to significant tree-contact outages during storms. Extreme heat waves can also strain the grid, particularly in the Chicago metro area where demand spikes from air conditioning. In southern Illinois, ice accumulation on power lines during winter storms is a major driver of extended outages.
How long do Illinois power outages typically last?
Most routine outages in Illinois are restored within 1 to 3 hours. Storm-related outages from severe thunderstorms typically last 4 to 12 hours. Major events — like derechos or widespread ice storms — can cause outages lasting several days, especially in rural downstate areas where crews must cover greater distances. ComEd publishes estimated restoration times on its outage map at comed.com, and Ameren Illinois provides updates at ameren.com. Both utilities also send outage alerts via text and email if you register your account.
