LOCAL CONDITIONS
What’s different in St. Charles.
The city owns the electric utility
St. Charles runs its own electric utility. It buys power through IMEA on a contract that lasts to 2035. In 2025 the city council turned down a 20-year extension and plans to look for a new supplier around 2029–2030. ComEd rebates don't apply to city electric customers.
IMEA programs don't cover water heaters
IMEA's home incentive programs, run through member cities, cover smart thermostats, central AC and air-source heat pumps. No water heater incentive is listed. Each member city sets its own incentive amount.
Wells that tap two aquifers
The city's 7 wells pull from a shallow sand-and-gravel aquifer and the deeper Galesville sandstone. A new deep well is being added.
