Ameren Illinois bill components
Ameren Illinois electricity rates include two core components: supply and delivery. The supply component covers the actual cost of the electricity, and the delivery component covers the cost of bringing electricity to the customer.
The supply charge is the price you pay per kWh for the amount of electricity you use in your home. The price of the electric supply is determined by your choice of supplier, whether it be an Alternative Retail Electric Supplier (ARES) or the electric utility. Ameren Illinois does not mark up energy supply charges. The supply section on your Ameren Illinois bill includes a "Supply Cost Adjustment," which is designed to allow the utility to recover costs associated with procurement, working capital, and uncollectible charges. The currently effective fixed Supply Cost Adjustment is 0.21 cents per kWh for all Ameren Illinois Rate Zones.
The delivery component covers the company's cost of bringing electricity to the customer, regardless of who supplies the energy. This component includes the cost of constructing and maintaining the delivery system to get electricity from the supplier to the customer.
The Ameren Illinois rate for the electric supply during the summer months (June through September) is different from the utility rate during the non-summer months (October through May). Over the course of a year, your average utility rate per kWh is likely somewhere between the summer rate and the non-summer rate. The average Illinois electricity rate is 15.25 cents per kWh, while the national average is 16.15 cents.
Additionally, you will notice a monthly "Purchased Electricity Adjustment" on your bill, which causes the electric supply charges to fluctuate from month to month. The purpose of this adjustment is to "true-up" any difference between what Ameren Illinois paid to acquire electric supply and what they charged their customers. Ameren Illinois does not expect this adjustment to be significant in the foreseeable future, and it is not included in the Ameren Illinois Price to Compare.

Ameren Illinois is an energy delivery company that provides electricity to residents and small commercial customers with electric demands of less than 150 kW.

Customers can also choose between single-bill and dual-billing options. With single billing, the supplier consolidates its electric supply charges with Ameren Illinois' delivery service charges, so the customer receives one bill from the supplier. On the other hand, dual billing means the customer receives two separate bills, one from Ameren Illinois for delivery services and another from the supplier for electric supply.
