The Ameren Illinois Energy Efficiency Program was developed in 2008 after Illinois lawmakers signed a rate relief act to encourage action through education, and to provide financial incentives to offset the cost of energy-saving upgrades. Since its inception, the Program has saved customers like you over $10 million in combined energy savings. We don’t just work in your community, we’re a part of it. We work with residents, businesses, and partners across Illinois to save our customers money, strengthen our state’s economy, and lower carbon emissions. Our goal continues to remain the same as it did in the beginning of the Program — to help our customers improve comfort, manage usage, and reduce costs.
Whether you own or rent your home, explore ways to save money and improve the comfort of your home.
No matter the size of your business, there are energy-saving opportunities to save money and time.
