Base Rates | Edwardsport/Environmental Compliance/CIP | Trackers

In the most recent IURC survey of residential electric utility rates, Duke Energy ranked third-highest among the 14 electric utilities under the IURC’s jurisdiction.

Approximately 61 percent of a typical Duke Energy residential customer’s bill pays the base rate (which traditionally covers most infrastructure and operating/maintenance costs) with the remaining 39 percent being recovered through rate adjustment “trackers,” as described below. *

Duke Energy Indiana's current electric base rates were approved on May 18, 2004.
