2026 Early Completion Bonus
We’re excited to announce the EARLY COMPLETION BONUS for Business Program energy efficiency projects finished in Program Year 2026. With this bonus, your facility can still receive up to 15% more incentive dollars to use toward your energy efficiency projects (see payout chart for details).* This not only reduces your out-of-pocket costs, but also helps to shorten your project payback period even further!
When you complete energy efficiency projects and submit applications to the Ameren Illinois Energy Efficiency Program, the bonus will be calculated automatically without the need for any additional paperwork.
This offer does not apply to the Small Business Direct Install Program and cannot be used in conjunction with any other special offers or bonuses. See below for additional restrictions.*
For 15% Bonus Amount Complete By March 31, 2026
For 10% Bonus Amount Complete By June 30, 2026
For 5% Bonus Amount Complete By Sept. 30, 2026
Made in Illinois Bonus
But wait, there’s more! If you’re an Ameren Illinois Business customer who purchases and installs Illinois-manufactured products in your facility while completing an energy efficiency project, you’ll also receive the MADE IN ILLINOIS BONUS! If your project qualifies, your facility can receive an additional 5% incentive dollars to your Early Completion Bonus to help support Illinois manufacturing. See payout chart for details.
