IURC Utility Rate Investigation, August 6 Fuel Tax Cliff, and Honda's Greensburg Hybrid Ramp
The IURC utility rate investigation into ROE and trackers, a August 6 fuel tax cliff, and Honda's Greensburg hybrid ramp, what Indiana operators do now.
Three formal developments landed on Indiana manufacturers' operating budgets this month: the IURC utility rate investigation into what investor-owned utilities are actually earning, a fuel tax holiday that expires overnight on August 6, and a 210,000-unit hybrid production load arriving at Honda's Greensburg plant. Each carries a date you can put on a calendar. All three hit the same 18-month planning window.

IURC Utility Rate Investigation Opens on ROE and Tracker Mechanisms
On July 15, the Indiana Utility Regulatory Commission released its energy affordability report and opened two formal investigations: one into the return on equity earned by all five Indiana investor-owned utilities, and a second into tracker mechanisms, the riders utilities use to raise rates outside standard rate cases. Both go to an August 7 public hearing.

The Gary Common Council and the Citizens Action Coalition are running a parallel fight in northwest Indiana. NIPSCO residential bills at 1,000 kWh rose roughly $83 per month between 2023 and 2025, the steepest jump among Indiana's five investor-owned utilities.

Fuel Tax Holiday Expires August 6 With No Renewal Path

Honda Loads Greensburg With 210,000 Hybrid Units by May 2028
Honda Global CEO Toshihiro Mibe told Yomiuri Shimbun on July 18 that Honda is considering an eighth North American plant. Its seven existing plants run at roughly 85% of 1.2 million units of U.S. capacity, against 2025 U.S. sales of 1.43 million.
Questions for Your Morning Huddle
Q: Will the IURC utility rate investigation actually lower our industrial power rates?
A: Not directly and not soon. The most likely near-term outcome of the IURC utility rate investigation is reporting requirements or methodology changes, with any authorized ROE reduction only reaching your industrial tariff at the next rate case filing.
Q: What happens to our fuel costs on August 7?
A: The 61-cent-per-gallon tax returns, and because the Gasoline Use Tax floats at 7% of a rolling retail average that is currently elevated, the effective restoration cost will likely exceed 61 cents. Audit freight contracts for fuel surcharge triggers before August 6.
Q: Are we too late to get into Honda's supplier pipeline for the Greensburg hybrid ramp?
A: Sourcing decisions for the May 2028 start are being made now, so the qualification window is open but closing. Call your Honda procurement contact this week to confirm realistic lead time for motor, inverter, or hybrid drivetrain qualification.
