In the most recent IURC survey of residential electric utility rates, Indianapolis Power & Light (IPL) ranked third-lowest among the 14 electric utilities under the IURC’s jurisdiction.
Approximately 71 percent of a typical I&M residential customer’s bill pays the base rate (which traditionally covers most infrastructure and operating/maintenance costs) with the remaining 29 percent currently being recovered through rate adjustment “trackers,” as described below.*
Indianapolis Power & Light Company's (IPL's) current electric base rates were approved on August 24, 1995, in Indiana Utility Regulatory Commission Cause No. 39938.
Environmental Compliance Projects & New Generation
IPL has received IURC approval for a $511 million plan to install new pollution control equipment at its Petersburg and Harding Street generating stations. For more information on this case (Cause No. 44242), please click here.
In a separate case, IPL is seeking approval to build and operate a new natural gas-fired generating facility in Morgan County, and to convert two coal-fired generating units at its Harding Street station to natural gas. This case (Cause No. 44339) is pending with more information available by clicking here.
In addition to base rates, IPL and other electric utilities recover and credit separate, specific costs through rate adjustment mechanisms known as "trackers." Rate adjustments via trackers are reviewed by the OUCC and approved by the IURC on a quarterly, semi-annual or annual basis.
IPL uses the following trackers:
Tracker Recovers Costs for Frequency IURC Cause No. Fuel Adjustment Clause (FAC) Coal and other fuels Quarterly 38703 Environmental Cost Recovery (ECR) Emissions control equipment (including operations & maintenance) Quarterly 42170 Demand Side Management (DSM) Energy efficiency programs Semi-Annual 43623 Green Power Rider (GPR) Program allowing customers to voluntarily buy renewable energy credits Semi-Annual 44121
All publicly filed documents in tracker cases can be reviewed by visiting the IURC's electronic document system and entering the appropriate docket number.
