Indiana regulators have launched an investigation into rising gas and electric bills across the state, responding to mounting pressure from both Democratic and Republican lawmakers and a surge in complaints from residents. The Indiana Utility Regulatory Commission (IURC) announced the “investigative inquiry” Wednesday, seeking to understand why Hoosiers are facing increasingly unaffordable energy costs. This action comes as state lawmakers consider legislation aimed at providing some financial relief to utility customers.
The IURC, a neutral state agency responsible for ensuring the safety, reliability, and reasonable rates of hundreds of utilities, will hold a public hearing on March 24. Presentations will be given by five investor-owned utility companies: AES Indiana, CenterPoint Energy Indiana, Duke Energy Indiana, Indiana Michigan Power Company, and Northern Indiana Public Service Company (NIPSCO). The hearing, scheduled from 9:45 a.m. To 4 p.m. At the PNC Center, will be livestreamed on the commission’s website.
New commission chair Andy Zay emphasized the need for balance, stating, “we want our ratepayers’ cost to be as little as possible, but we also want our utilities to be successful, so when we turn the switch, the lights come on.” He acknowledged that this balance “feels dramatically out of whack right now for many, many Hoosiers.” The inquiry represents a first step toward addressing what Zay described as an “energy affordability crisis” across the state.
Bipartisan Concerns Drive Investigation
The IURC’s decision follows months of growing concern from state legislators on both sides of the aisle. In September, five Democratic state representatives from Northwest Indiana wrote a letter expressing “serious concern about the growing strain high utility bills are placing on our constituents and the lack of transparency surrounding these costs.” Then, on January 27, a dozen Republican lawmakers sent a similar letter to the commission, citing a “significant rise” in complaints from their constituents regarding NIPSCO’s gas and electric bills.
The Republican lawmakers’ letter highlighted particularly stark figures: NIPSCO customers experienced over a 90% increase in electric bills in July 2025 compared to 2016. The letter also noted that NIPSCO has some of the highest residential consumer rates of all electric utilities reported to the U.S. Energy Information Administration. These statistics prompted the lawmakers to request an investigation into whether NIPSCO’s rates have become “unreasonable or unjustly discriminatory.”
Rising Costs and Legislative Responses
Indiana’s electricity costs have been on the rise, according to a recent Congressional report. In response, state lawmakers are considering legislation that would place utility customers on levelized billing plans, designed to spread costs more evenly throughout the year. Governor Mike Braun has also signed other energy-related laws into effect.
Zay indicated the commission intends to take a comprehensive approach, stating, “We’re going to ask questions on the rates, on the transparency of billing, and also on reflection to understand better what we have done right and what we have done wrong as a commission, to set a tone for what will come next.” He emphasized the importance of hearing directly from residents and plans to travel around the state to hold community meetings.
What’s Next for Indiana Utility Customers
The IURC’s fact-finding inquiry is intended to inform the commission’s next steps in addressing the affordability crisis. Zay said the commission wants to be “transparent, get some answers and have some open dialogue” to define the scope of the investigation. The commission is seeking to understand not only the current cost drivers but also how its own past decisions may have contributed to the problem.
The March 24 public hearing will be a key opportunity for utility companies to present their perspectives and for the IURC to gather information. Residents can also follow the proceedings via the livestream on the commission’s website. The IURC plans to continue gathering input from stakeholders and the public as the investigation progresses.
The investigation into rising utility bills is ongoing. The IURC’s next step will be to analyze the information presented at the March 24 hearing and determine the appropriate course of action. Residents are encouraged to stay informed about the process through the IURC’s website and to contact their state representatives with any concerns.
