Power bills in DuPage County
Most of the county is served by ComEd.
This case does not change what a household pays today, but it is the main tool Illinois regulators are using to try to stop the cost of new grid equipment for data centers from landing on residential bills. ComEd annual reconciliation rate case (docket 25-0383) adds about $3.10 a month to a typical bill from January 2026. PJM capacity auction price spike hits ComEd supply charges adds about $10.50 a month to a typical bill from June 2025.
Under an Illinois law that lets ComEd true up its grid plan spending every year, the utility asked to recover 268.5 million dollars in a reconciliation case. The Illinois Commerce Commission approved 243.1 million dollars on December 18, 2025, cutting about 25.4 million dollars including costs tied to a mismanaged customer billing system rollout. Citizens Utility Board estimated the approved amount adds about 3.10 dollars a month to a typical residential bill starting in 2026.
