Learn About Your Utility, Ameren Illinois

Ameren Illinois is an electricity and natural gas utility that provides power to more than 2 million energy consumers spanning a 43,700 square-mile territory throughout central and southern Illinois. Ameren Illinois is strictly an energy distributor, separate from the various retail electric suppliers in Illinois’ energy supply market.

What does an open energy market mean for consumers?

Unlike many states, residents of Illinois have the freedom to choose a retail electric supplier or retail gas supplier rather than being limited to getting their chosen resource from their local utility. Illinois electric rates on supply vary, so this power to choose can help consumers pick the best plan for their budget.

Ameren Illinois prioritizes energy efficiency

Ameren understands the importance of the economic and environmental impacts of saving energy. To encourage consumers to do the same, the utility offers incentives such as discounts on energy-efficient lighting and smart thermostats from participating retailers.

Ameren Illinois will remain your utility

Regardless of which retail electric supplier you choose, Ameren Illinois will be your utility if you live within its service area. Ameren Illinois’ primary responsibility is electric and gas delivery and infrastructure maintenance, while the duty of an electrical supplier is to offer supply plans. In Illinois, Ameren maintains its infrastructure that includes 4,500 miles of electric transmission lines, 46,000 miles of distribution lines, 18,200 miles of natural gas transmission pipes and 12 underground natural gas storage fields. If this system ever experiences a maintenance issue, such as a power outage or gas leak, Ameren’s crew will get things back to working order again once they are notified about the problem.
