NIPSCO Electric Rates
Pending cases for Northern Indiana Public Service Company’s (NIPSCO’s) electric utility include its:
- Rate Case (IURC Cause No. 45772)
- Pending fuel cost adjustment (Cause No. 38706-FAC139)
- Proposed Appleseed Solar/Templeton Wind projects (IURC Cause No. 45887)

- Coal ash compliance project: Schahfer (IURC Cause No. 45797)
- Coal ash compliance project: Michigan City (IURC Cause No. 45700)
- Trackers under its approved 7-year infrastructure plan (IURC Cause No. 44733)
In the most recent IURC survey of residential electric bills, NIPSCO's monthly bill for 1,000 kWh ranked third-highest among the utilities under Commission jurisdiction.
Base rates cover most infrastructure and operating/maintenance costs while rate adjustment “trackers,” as described below, allow for more frequent rate changes for specific costs as designated by law. The trackers were re-set when NIPSCO's current base rates were approved in 2019 and are still subject to adjustments every three, six, or 12 months.

Current base rates for NIPSCO's electric utility were approved in 2019.
Trackers
In addition to base rates, Indiana 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.
NIPSCO uses the following trackers, which comprised approximately 26.7% percent of a residential customer’s typical bill as of March 2023. All filings are available by entering the cause number in the IURC's Online Services Portal.
