Electric Rates
What Makes Up Your Electric Bill
Monthly Charges
Residential Electric Utility customers pay a monthly customer charge and a monthly energy usage charge per kilowatt hour (kWh). The monthly customer charge provides a stable revenue source to cover the fixed costs of the utility, while energy charges are based upon customers’ individual energy usage.
In addition to these charges, certain classes of commercial customers also see a monthly demand charge on their bills.
2022 Rates
In 2021, the Electric Utility conducted a rate study to determine the appropriate amounts to charge through 2024 so that the cost of operating the utility is covered. All customer classes will see no increase in their electric rates in 2022 and a 1% increase in 2023 and 2024.
As of January 2022, the average residential electric customer is paying $105.74 per month on their electric bill; this is almost 9.6% lower than ComEd’s residential rates.
Below is a table outlining charges to the most common customer classes effective January 2022. Commercial customers are encouraged to utilize the averages provided to help calculate their bills, as bills can vary widely from one business to the next.

Purchased Power Adjustment
The Purchased Power Adjustment (PPA) first appeared on utility bills in Naperville in 2016. This is a monthly adjustment on your electric bill based on actual power costs. The PPA changes monthly and is based on a six-month rolling average. During each utility rate study, the PPA baseline is adjusted to account for projected electricity costs so that the PPA is ultimately revenue neutral to the utility.
Take a look at the below graphic to learn more about what a PPA means for your monthly electric bills.
