Illinois Electric Choice

Residential customers have been able to participate in electric choice and compare Illinois electricity rates since 2002, but major competition didn’t come about until 2007 when the deregulation transition was finalized. Since then, retail electricity providers (also known in Illinois as ‘alternative retail electric suppliers’ or ‘ARES’) have been gaining customer by offering rates much lower than the default utilities.

Compare Illinois Electricity Rates

The most important thing to consider when selecting a retail electricity provider is rate pricing. You’ll want to find a retail electricity provider that offers a lower rate than what you are currently paying, which is referred to as the “Price-to-Compare” and can be found on your utility bill. This rate is expressed in cents per kWh. Keep in mind, even a slight difference can result in large cost savings.

There are other factors that you will want to consider before switching:

  • Variable v. Fixed Pricing – Variable pricing can vary by day or month, is based on the market price for the retail electricity provider, and can be very unpredictable. With fixed pricing, customers can pay one low rate that will never change until the contract expires.
  • Length of the Contract – Contract terms can last for as little as one month or as long as 36 months. Shorter contracts may offer lower rates, but longer contracts lock in low rates for long periods and reduce the risk of high rates when if contract expires. The ICC recommends choosing a 12- or 24-month contract to avoid risk.
  • Other Switching Incentives –Some providers offer sign-up bonuses, rewards programs, guaranteed savings, and more.
  • Green/Renewable Electricity – Looking to be more environmentally conscious? Many providers offer partial or 100% renewable electricity options as well as Renewable Energy Certificates (RECs) to residents and small businesses. While the rates are higher than traditional electric sources, the availability of renewable electricity has driven costs down and can often be found for less than the utility’s Price-to-Compare for traditional electricity.
