Interstate Power and Light (Alliant Energy) offers residential energy efficiency rebates and incentives for Iowa customers for a variety of technologies. Rebates are available for certain HVAC equipment, appliances, lighting, doors and windows. 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 website.
The Appliance Awards and the Replacement Doors and Windows Programs offer rebates for energy efficient clothes washers, dishwashers, refrigerators, freezers, room air-conditioners, windows, and doors. All appliances must be Energy Star and meet certain efficiency requirements listed on the program web site. The Insulation Incentive is part of the Home Energy Audit process; residential customers may be eligible for a rebate of up to $750 for qualifying insulation.
IPL also offers incentives 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. Contact IPL for additional information on these programs.
