Hoosiers are paying historically high energy rates from Indiana’s investor-owned utilities, according to a new analysis by a consumer watchdog group.
Citizens Action Coalition collected and analyzed 20 years of data from five of the state’s monopoly utilities — NIPSCO, CenterPoint, Duke Energy Indiana, AES Indiana and I&M — and found residents were hit this year with the highest year-over-year price increase since at least 2005.
The group’s key findings show a statewide average energy bill increase of more than $28 per month — a 17.5% jump.
The Indiana Energy Association, in a written statement in response to the CAC report, said its members “are committed to keeping affordability top of mind, while also making the investments needed to provide reliable electricity.”
Kerwin Olson, executive director of CAC, said for years Indiana lawmakers have passed utility-friendly legislation shifting economic risk and cost on to Hoosiers already facing rising costs for housing, healthcare and other bills.
“This is an ongoing trend of continuing to use rate payers as economic development tools while inappropriately shifting all of the investment risk of running the utility away from utilities themselves and their investors onto shareholders,” Olson said. “And that comes at a cost, and that cost is starting to display itself as extraordinary rate increases.”
The continued increase in utility bills is exacerbating an affordability crisis, he said, and Indiana is the epitome of regulatory and legislative control by investor-owned utilities that dictate policy and regulatory outcomes. The state, Olson said, needs to get serious about looking at policy solutions that invite competition and provide customers with a choice rather than allowing monopoly pricing.
“Let’s get serious about making sure the everyday working class Hoosier can live their life with some dignity and afford the daily cost of living,” he said.
Indiana’s monopoly utility rate increases
CAC’s analysis of data from the Indiana Utility Regulatory Commission shows large year-over-year bill increases for Hoosier’s residential energy bills between July 1, 2024, and July 1, 2025.
The Indiana Energy Association noted “Indiana has been growing, and Indiana’s utilities have an obligation to keep pace with that demand and power a modern economy.”
The association wrote that Indiana’s energy companies invested in additional power generation and modernization of the electric grid that delivers that power.
“We’ve added advanced technology to the electric grid that reduces power outages and hardens the grid against severe weather. There also have been substantial investments in evolving environmental regulations,” the statement says.
NIPSCO customers, the ratepayers already paying the most, saw the largest increase of $50, or 26.7%, per month, according to CAC. NIPSCO spokeswoman Tara McElmurry told IndyStar the company is aligned with IEA’s statement and has nothing further to add.
CenterPoint customers saw a $44 per month increase, or 25%, over the last year following an IURC-approved rate increase. CenterPoint spokesperson Noah Stubbs referred IndyStar to IEA’s statement.
Duke Energy Indiana customers saw a $26 increase on their monthly bills. Angeline Protogere, spokeswoman for Duke Indiana, wrote in an email to IndyStar that Duke has the lowest average rate among major utilities in Indiana for residential users, and that the year-over-year survey includes base rates as well as fuel and purchased power costs, which fluctuate quarterly. New rates allow Duke to continue making investments in a variety of ways including outage resilience, increasing reliability and transmission infrastructure among other things.
“We have invested $1.6 billion in our electric grid, power plants and overall system on behalf of our customers, and that is reflected in a base rate increase that went into effect in February 2025,” Protogere wrote.
AES Indiana residential customers paid about $17 more each month, and the utility recently filed for another rate increase. AES did not comment but instead referred IndyStar to the IEA statement.
I&M customers saw bills rise $6 a month. I&M did not immediately respond to IndyStar.
Energy affordability talks in Indiana
Gov. Mike Braun ran his gubernatorial campaign, in part, by promising lower energy costs for Hoosiers, and state lawmakers referenced affordability during legislative session this year.
These promises have yet to come to fruition, and Olson said lawmakers continue to compound the issue of energy bills running rampant with laws such as Senate bills 424 and 423 which shifted even more costs onto Hoosiers. He also pointed out Braun’s new Strategic Energy Growth Task Force, meant to address affordability, lacks any consumer advocates.
“It’s hard to believe we’re serious about affordability when a task force like that lacks a consumer voice,” Olson said. “And then we see numbers like these: rate increase after rate increase after rate increase with no end in sight and with no apparent desire from the state to seriously take a look at why and try to fix the problem.”
Olson and CAC are not opposed to economic development and growth, but he said the risks need to appropriately be shared and something needs to change.
“All we want to do in Indiana is build, build, build in the name of energy dominance, and rate payers be damned,” he said.
