Alliant Energy - Interstate Power and Light (IPL) offers rebates for high efficiency equipment for commercial customers. Rebates are available for windows/sashes, programmable thermostats, water heaters, furnaces, boilers, and custom measures. Heating incentives vary by the efficiency of the installed unit. All boilers and furnaces must meet program efficiency and installation requirements. Water heaters are eligible for a rebate of $50, while programmable thermostats are eligible for a $25 rebate. In addition, windows/sashes with a U-factor of .30 or less are eligible for a $20/unit rebate.
Custom projects, which vary greatly, are awarded for the completion of projects which attain significant energy savings but are outside the scope of the prescriptive offerings. Customers who are planning to implement a customized energy saving retrofit should contact IPL for more information. In addition to these rebates, Alliant-IP&L offers financial incentives for customers who have their energy load voluntarily curtailed during peak periods. More information can be found at the program web site.
