Questions
Does it really cost nothing?
For qualifying customers the assessment is free and many upgrades cost little or nothing. It depends on the program, the home and the program's rules. We'll tell you up front if anything would cost you money.
What are the income limits?
They depend on household size and are set by Ameren Illinois each program year. Call us and we'll check the current numbers with you.
I rent. Can I still take part?
Often, yes. Renters of a house or duplex may qualify for HEIQ, and 3+ unit buildings are served through the owner. Some upgrades need the owner's approval.
Is Green Titans Energy part of Ameren?
No. We're an independent contractor registered as an Ameren Illinois Program Ally. Ameren Illinois runs the programs and decides eligibility; we help you apply and do the qualifying work.
