In the most recent IURC survey of residential electric utility rates, Vectren Energy Delivery ranked highest among the 14 electric utilities under the IURC’s jurisdiction. Vectren’s electric utility serves six southwestern Indiana counties.
Nearly all of a typical Vectren residential customer’s electric bill pays the base rate (which traditionally covers most infrastructure and operating/maintenance costs) with a small portion being recovered through rate adjustment “trackers,” as described below. *
Vectren Energy Delivery of Indiana's current electric base rates were approved on April 27, 2011.
