The IUB is responsible for energy efficiency programs and energy efficiency plans of Iowa investor-owned utilities. Energy efficiency plans in Iowa address both electric and natural gas usage through a variety of programs that attempt to give all customers opportunities to participate.
To review the law that established Iowa Energy Efficiency, see Iowa Code chapter 476.6(13) and (15).  Additionally, changes enacted during the 2019 Legislative session can be found in Senate File (SF) 638.
Rules that apply to Energy Efficiency can be found in the Utilities Division section of the Iowa Administrative Code 199 chapter 35.
For more information, contact Don Tormey at 515-725-7347 or don.tormey@iub.iowa.gov.
