NIPSCO Tracker Filings Land Inside a Statewide Regulatory Reckoning

Governor Braun directed the Office of the Utility Consumer Counselor to file a complaint against NIPSCO this week. Here is what that complaint lands on top of.

NIPSCO filed three separate electric rate tracker increases on August 11, 14, and 20 (totaling $7.33 per month) in the immediate aftermath of the August 11 derecho that left hundreds of thousands without power across Northwest Indiana. As of Tuesday afternoon, 3,051 NIPSCO customers were still without power, including 2,271 in Gary alone.

The headline number misses the structural problem. These trackers proceed on a separate statutory track from the storm investigation Governor Braun ordered, which means NIPSCO can simultaneously pursue cost recovery through tracker mechanisms while being investigated for whether it correctly spent what was already approved. NIPSCO customers paid over $81 million specifically for vegetation management from 2023 to 2025. The IURC had already denied NIPSCO's $741 million transmission improvement plan before the derecho hit. That creates a direct contradiction in the regulatory record: NIPSCO was told to spend less on the infrastructure that just failed, and is now under investigation for how it spent what was previously authorized.

If the IURC finds material underinvestment, the exposure is clawback orders and mandatory spending mandates, not the $7.33 monthly tracker number that is dominating coverage.

For industrial customers like NLMK Indiana and U.S. Steel (named NIPSCO customers in prior rate agreements) these August filings may be among the last of their kind. Chairman Swinger has put tracker elimination on the table ahead of the 2027 legislative session, and the Office of the Utility Consumer Counselor's complaint filing is the next docketed action to watch.

The immediate action for your facility: get your backup power and load-curtailment posture reviewed before a second outage forces the question. The IURC investigation timeline is moving toward the 2027 legislative session. Your exposure audit should move ahead of it.
