Investor-owned Utilities (IOUs) Energy Efficiency Program Overview

Key features of all plans and programs approved for IOUs include:

  • Plans must be cost-effective, with four benefit-cost tests used to determine cost-effectiveness from the perspectives of the participating customers, the utility, the combination of the utility and customers, and the impact on utility rates.
  • Plans must include programs for all types of customers.
  • Plans must include an analysis of potential for energy efficiency, and must include performance standards in terms of energy and capacity savings.
  • IOUs recover costs through an automatic rate pass-through, reconciled annually to prevent over-recovery or under-recovery.
  • The IUB is authorized to conduct prudence reviews of IOU energy efficiency, with authority to disallow imprudent costs.

Investor-owned utilities offer many energy efficiency programs. The IOUs’ plans include programs based on proven strategies and pilot programs which test new methods of helping customers reduce energy consumption. Programs typically target customer classes or subgroups of customers, and often provide rebates or loans for energy efficient equipment or building components. To find out which programs are currently underway for various types of customers, and what customer incentives may be available, go to the web sites of the IOUs as follows:

Alliant Energy / Interstate Power and Light Company
