Indiana Opens ROE Probe as US Utility Profits Draw Regulatory Fire
Indiana's new investigation into utility returns and cost-recovery trackers signals a toughening regulatory mood that equity investors in US utilities cannot ignore.
Indiana's utility regulator launched formal investigations on Wednesday (2026-07-15) into the returns on equity earned by utilities operating in the state and the "trackers" that let them recover certain costs outside of standard rate cases — a direct regulatory challenge to the earnings mechanisms that have underpinned utility stock valuations for years.6
The gap between authorized and actual returns gives a sense of what the Indiana Utility Regulatory Commission found worth investigating. American Electric Power's Indiana Michigan Power subsidiary carries an authorized ROE of 9.85%, according to AEP's most recent annual report filed with the U.S. Securities and Exchange Commission. Over the 12 months ending March 31, it earned 12.6%, per AEP's own figures.6
Jefferies equity analysts flagged the exposure on Thursday (2026-07-16), writing that the tracker review "could tighten rider recovery" and that guidance around the TDSIC infrastructure program "raises the bar on benefits/cost justification for infrastructure plans." The IURC has also indicated that 9.1% to 9.9% is a reasonable authorized ROE range — a signal that any reset could compress the gap with what utilities are actually earning.6
The IURC's move is not happening in isolation. The national average price of residential electricity rose roughly 7.3% from April 2025 to April 2026, reaching 18.8 cents per kilowatt-hour, according to a report from the North Carolina Clean Energy Technology Center. Over 50% of US households surveyed reported seeing their electricity bills increase; 31% saw monthly increases exceeding $50. Low-income households already spend 17.8% of their income on energy bills and transportation fuel, more than three times the national average.5
That affordability pressure is giving state regulators political cover to ask harder questions about utility cost structures. Trackers — mechanisms that allow utilities to recoup specific capital expenditures between rate cases without full regulatory review — have long been criticized by consumer advocates as a way of insulating utilities from the scrutiny applied in formal proceedings. Indiana is now examining whether that insulation has held too well.6
Exelon CEO Calvin Butler, speaking earlier this year in his capacity with the Edison Electric Institute, acknowledged the industry faces a different political environment than it did at the start of 2024. Utilities spent years advocating for electrification alongside Democratic-led policy support; that alignment has frayed as bills climbed. Some blue-state legislatures have moved to cut energy-efficiency programs — typically a utility-preferred tool — under pressure to deliver near-term bill relief, according to Canary Media.4,3
The European dimension of the same debate is sharper. Analysts told Montel during the week of May 18 (2026-05-18) that EU energy majors had been pocketing what they described as "the elephant in the room" — outsized profits tied to the conflict-related energy crisis. EU energy commissioner Dan Jorgensen characterized that crisis during the same period as "as serious as the 1973 and 2022 crises combined." BP was tracking toward a doubling of first-quarter profit to GBP 2.7 billion, per Montel's reporting. Whether European regulators move to recapture those gains, as some analysts urged, remained unresolved as of that reporting.1
In the UK, separately, authorities moved on May 21 (2026-05-21) to close a tax structure that officials said had allowed multinational energy firms to sharply reduce taxes on profits from UK operations. The move tightened pressure on an oil and gas sector already navigating the UK windfall levy framework.2
Back in Indiana, the immediate question for utility investors is sequencing. ROE investigations take months to complete; tracker reviews can move faster if the commission limits recovery mechanisms through guidance rather than waiting for full rate cases. Jefferies' caution on the TDSIC infrastructure program matters because capital deployment plans often rest on the assumption that tracker recovery will remain intact. A tighter bar on cost justification means projects that looked economically obvious under current rules may need to be repriced.6
The broader industry argument — that rising demand from data centers justifies accelerated infrastructure investment, and that consumers will benefit over time from spreading fixed costs across a larger load base — has not landed with legislatures or regulators dealing with constituents opening bills. One analyst quoted in IURC proceedings put it plainly: telling someone their pain is increasing more slowly is not an effective political message.6
Watch for whether other state commissions follow Indiana's lead on tracker scrutiny. A 14.4% gap between utility investment in programs for income-limited customers and the prevalence of low-income households, identified in 2024 program reports cited by the NCCET, gives advocacy groups a number to work with in future proceedings.5
