Customer Electric Choice

In Illinois, electricity customers’ monthly energy bills have two main elements: a supply charge and a distribution/delivery charge. The supply charge is the cost of energy generation, such as the energy produced at a power plant. The distribution/delivery charge is the cost to transport the energy across the electric grid from the power producer to the customer.

To provide customers electricity supply in Illinois’ deregulated, restructured electricity market, energy producers sell electricity into competitive wholesale power markets, and then retail energy suppliers purchase this electricity to sell it to customers.

Customers of Ameren Illinois, ComEd, and MidAmerican Energy may choose who provides their electricity supply. The ICC has created an educational website, Plug In Illinois, with information on electric utility distribution rates, retail electric supply options, real-time electricity pricing, and additional ways to conserve energy and save money on utility bills.  

To learn more about electric choice and what it means, please visit the ICC’s Plug In Illinois website.

For ease of comparison, the Plug In Illinois website lists the Price to Compare that breaks down customers' charges on their monthly electricity bills from Ameren Illinois and ComEd. 

The IPA has assembled information in the links below about ComEd and Ameren Illinois electricity supply options so that Illinois ratepayers may make an informed choice about their electricity supply.
