How it works


  • Complete the interest form. For questions, email us at [email protected] or call the Alliant Energy Business Resource Center at 1-866-ALLIANT (866-255-4268).
  • Your contractor will evaluate current equipment, identify improvement opportunities and provide a proposal with upgrade recommendations, project costs, payback and rebate information. If your contractor isn't on our list of trade allies, make sure they sign up so you can receive your rebates.
  • Schedule the projects you approve with your contractor.
  • Our rebates pay a fixed amount for tuneups and up to 70% of project costs for lighting and refrigeration retrofits directly to your contractor. You simply pay the balance.
  • Enjoy long-term savings on energy costs.

To qualify for the BES program, you must be an Iowa business customer receiving electric service from Alliant Energy.

Testimonials from our customers

Clausen logo
"After having an energy audit completed last year at one of our warehouses, we were informed of the tuneup rebates available for doing preventative maintenance on our HVAC and refrigeration units. The Business Energy Solutions program worked with our contractor to make sure we received those incentives. Our HVAC specialist took care of the leg work, and we were able to save money on a service that makes sure our equipment is in good order and running efficiently."

Matt Burken, president of Clausen Companies, Clinton, lowa
