Ameren Illinois

Ameren Illinois is a utility company based in Collinsville, Illinois. It provides electricity to more than a million customers and natural gas to over 800,000, located in 89 counties throughout Illinois. Ameren’s service territory covers approximately 3/4 of the state, including Peoria, Carbondale, and Springfield. Its parent company is Ameren, which also owns Ameren Missouri. Incorporated in 1995, Ameren merged three of Illinois’ utility companies into a single entity, Ameren Illinois, in 2004.

The term “deregulation” sounds complex, but it simply means that you have the power to choose an energy supplier rather than being limited to only one option – your utility. Illinois deregulated its energy market in 1997, allowing private suppliers to compete with utility companies such as Ameren. By 2008, Illinois customers had many different options for power suppliers. Because you have several different choices, it’s important to carefully compare Ameren utility rates with those of other suppliers in your area.

Note that deregulation does not mean a lack of oversight. The Illinois Commerce Commission oversees all Illinois public utilities. You can contact them to resolve any disputes you may have with your supplier.

Something about deregulation that may be tough to wrap your brain around is the difference between a utility and a supplier. A utility is a company that delivers electricity and/or natural gas to your home, while a supplier is a company that provides the service. Ameren Illinois is a utility, though it also supplies service to those who choose it or do not make a decision at all. If you live in Ameren’s service area, you will call them about outages, since they are responsible for the lines and infrastructure, regardless of which supplier you use.
