Interstate Power and Light (Alliant Energy) offers residential energy efficiency rebates to Iowa customers for a variety of home upgrades. Rebates are available for certain heating, insulation, water heating and building envelope measures. Rebates are available for energy efficient windows and sliding doors which meet program efficiency and installation requirements. All equipment must meet certain efficiency requirements listed on the program web site. Landlords and renters of multi-family homes can also take advantage of various cash-back rewards for energy-efficient equipment in the residential and commercial programs. Equipment must meet efficiency levels specified on the program web site.

IPL also offers base rebates through the New Home Construction Program. The exact rebate level varies depending on the square footage of the home, and whether or not the home receives heating and/or cooling energy from Alliant Energy-IPL. Bonus rebates reward customers for installing premium-efficiency heating and cooling equipment, clothes washers, refrigerators and lighting.
