In the most recent IURC survey of residential electric utility rates, Indianapolis Power & Light (IPL) ranked eighth among the 14 electric utilities under IURC jurisdiction.
As of July 2016, nearly 91 percent of a typical IPL residential customer’s bill paid the base rate (which traditionally covers most infrastructure and operating/maintenance costs) with the remaining 9 percent recovered through rate adjustment “trackers,” as described below.*
IURC Cause No. 44893
IPL is requesting approval of new base rates in a newly filed case with the IURC. A procedural schedule will be set in the near future. For more information, click here.
