Interstate Power and Light (IPL) offers a wide variety of incentives for commercial customers to save energy in eligible facilities, whether they are upgrading existing facilities or building new ones. IPL also offers a free business energy audit program. 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.

Existing Facilities IPL offers standard rebates for a variety of appliances; heating, cooling and hot water equipment; building shell improvements; lighting and ceiling fans; commercial food service equipment; premium efficiency motors and variable speed drives; and vending machine controllers. A Cash Rewards Booklet can be found on the program web site outlining incentive amounts and program guidelines.

Commercial New Construction IPL's Commercial New Construction program offers commercial customers incentives for both the design of high efficiency buildings as well as the construction. Design team incentives are based on the square footage of the building. Construction incentives are per kilowatt-hour plus an additional per therm rebate. Further information on incentive amounts, construction specifications, and how to apply are located on the program web site.
