Electric Rates

Residential customers pay a monthly service charge and a monthly energy consumption charge per kilowatt hour (kWh). Electric rates are set by the Naperville City Council and can be found in the municipal code book (Title 8, Chapter 1, Article C).

Naperville enjoys some of the most competitive electric rates in the greater Chicago area when compared to communities serviced by ComEd or through municipal aggregation contracts.
