Energy-Saving Opportunities for
Eligible Residential Customers

The Ameren Illinois Energy Efficiency Program is committed to helping you find ways to improve comfort, manage usage and reduce costs. By participating in one of our energy-saving opportunities, homeowners, renters and multifamily property owners and managers can save energy while lowering their costs.

The first step to find out where your home might be wasting energy is through a Home Energy Assessment. A Home Energy Assessment looks for ways to reduce your energy usage and costs. Through this Assessment, you may be eligible to receive energy-saving upgrades at little to no cost, such as improved insulation, heating equipment and ventilation. 


Need financial assistance? The Energy Assistance Foundation can help! The Energy Assistance Foundation provides year-round bill payment assistance to help low-to-moderate income customers of Ameren Illinois.

Residential customers living eligible ZIP codes can receive a FREE smart thermostat.

Switching to heat supplied through electricity instead of propane not only saves you money on heating costs, but it gives you the convenience and reliability of using Ameren Illinois electric already being used in your home.

As a renter, you may feel as though you don’t have control over the energy costs in your home. But there are many no-cost and low-cost opportunities to save energy without making any major changes to your space.

If you own or manage a multifamily property, we may be able to help you and your tenants save energy, reduce water usage and lower water heating costs. Request a FREE Energy Assessment for your property. After your Assessment you will receive a comprehensive list of available upgrades and incentives that are available for your property.

Ameren Illinois Program Staff is available to provide technical and financial assistance to Public Housing Authority (PHAs) to improve tenant comfort, manage usage and reduce costs. PHAs are eligible to receive incentives for energy efficiency upgrades for their projects that service income eligible residents. Ameren Illinois can help you with the development of your plans at the start of your project to maximize eligible incentives.
