What are the incentives?

We offer incentives ranging from $700 to $4,400, depending on the square footage of your home, the level of your incentive package and whether or not your home receives heating and/or cooling energy from Alliant Energy.

And as an extra benefit to you, Alliant Energy now offers three levels of incentives – base, bonus and super-bonus:
  • The base incentive is awarded for homes that qualify for an ENERGY STAR® rating and meet the minimum building standards outlined by Alliant Energy.


  • Bonus incentives are available for installing premium efficiency heating and cooling equipment, water heaters, clothes washers, refrigerators, dishwashers and lighting.


  • The super-bonus incentive is available to homeowners and/or builders who utilize all the bonus incentives.

Incentives are given for single-family dwellings or duplexes only. Duplex incentives may be less, depending on the type of construction and square footage.

What are the requirements?
Your home must meet minimum energy efficiency standards outlined in the specifications and incentives [PDF format]. Your builder can explain the minimum standards and help you determine the total amount of your incentive.

How do I qualify?

  • To qualify for an incentive, all homes must first be inspected by an energy expert identified by Alliant Energy.


  • Participants must be Alliant Energy customers in Iowa. Homeowners who receive electricity from a municipal utility or a rural electric cooperative that purchases electricity from Alliant Energy are not eligible for incentives.


  • Incentives are given for single-family dwellings or duplexes only. Duplex incentives may be less, depending on the type of construction and square footage.

  • Incentives may be paid to the builder or the homeowner and should be agreed upon between the two.
