The U.S. Department of Energy and the North Carolina Clean Energy Technology Center are excited to announce that a new, modernized DSIRE is under construction. The new version of DSIRE will offer significant improvements over the current version, including expanded data accessibility and an array of new tools for site users. The new DSIRE site will be available in December 2014. Staff are currently working hard on the new version of DSIRE but are also maintaining the content of the current version of DSIRE. Thank you for your continued support and patience during this transition. We hope you are as excited for December as we are!

2008 IUB Order

In 2008, Iowa enacted S.B. 2386, which requires the Iowa Utilities Board (IUB) to create energy savings standards (electricity and natural gas) for all rate-regulated utilities. The IUB ordered utilities to reduce retail sales by 1.5% of average sales for the previous 3 years by December 31, 2011.* Utilities that are not rate-regulated (municipal and cooperative utilities) were required to establish their own energy efficiency goals. These goals were filed in December 2009. All utilities (rate-regulated and otherwise) must submit plans with the IUB utility, administer customer energy efficiency programs in order to reach the efficiency goals, and submit annual reports to the IUB describing energy efficiency efforts. Utility efficiency plans, operating plans, and annual reports can be found here.

A utility may reduce energy consumption through improvements to its infrastructure or through customer programs. Examples of customer programs include energy studies and audits, education, director rebates and other financial assistance, research projects, time-of-use-rates, tree planting, and hot water insulation distribution programs. All programs must be cost-effective for both customers and the utilities.

*The Iowa Utilities Board has approved goals of approximately 1-1.2 percent for the natural gas programs of investor-owned utilities. The IUB also approved lower electricity efficiency goals for Interstate Power and Light Company. MidAmerican Energy Company reached 1.5% electricity savings in 2010.
