NIPSCO Electric Rates
Northern Indiana Public Service Company’s (NIPSCO’s) residential electric rates ranked second-highest among the utilities the IURC regulates as of July 2019. *
Major components in a typical electric bill include base rates, trackers, and sales taxes.
Base rates cover most of a utility’s operating and maintenance costs. They made up about 89 percent of a typical NIPSCO residential electric bill as of July 2019.
NIPSCO's new base rates were approved in December 2019. For more information, click here.
Electric base rates prior to 2016 were approved in 2011. The OUCC's December 2011 news release offers a summary. The 2011 order resolved issues that were raised in NIPSCO’s prior electric rate case. The OUCC’s May 2009 news release summarizes the agency’s testimony.

In addition to base rates, NIPSCO and other electric utilities recover and credit separate, specific costs through rate adjustment mechanisms known as "trackers." The OUCC reviews all tracker rate adjustments in IURC cases on a regular basis.
NIPSCO is authorized to use 7 electric trackers. They made up approximately 11 percent of a residential customer’s typical bill as of July 2019.
The largest tracker is the Transmission, Distribution, and Storage System Improvement Charge (TDSIC). The IURC has approved a settlement agreement among NIPSCO, the OUCC, and additional parties on the utility's proposed 7-year plan for infrastructure improvements, including approval of a the tracker to recover the costs.
