Indiana Launches Major Investigation into Rising Utility Costs

By Andi Anderson

Indiana utility regulators are preparing for a major investigation into rising energy costs after growing complaints from customers across the state. The Indiana Utility Regulatory Commission (IURC) announced that it will hold an affordability inquiry involving the state’s five largest investor‑owned utility companies.

The decision marks a rare move for the typically reserved agency, as new Chair Andy Zay noted during a press conference. He said, “We’re a regulatory agency. … It’s not typically our style as a commission to get involved in these issues,” explaining that the Commission was responding to an increasing number of concerns from customers and community leaders.

The IURC’s role is to ensure that utilities provide reliable and safe service at fair prices. However, Zay acknowledged that many residents feel this balance has shifted, stating, “That balance feels dramatically out of whack right now for many, many Hoosiers and today is the beginning of a process that we are labeling an investigative inquiry.”

He added that the Commission is asking utilities to participate in an open discussion about rates and billing practices.

The investigation will include AES Indiana, CenterPoint Energy Indiana, Duke Energy Indiana, Indiana Michigan Power Company, and Northern Indiana Public Service Company.

Zay explained, “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.”

Industry leaders expressed their views as well. Indiana Energy Association President Danielle McGrath said the industry is “committed to serving our customers reliably and affordably.” She emphasized that system investments supporting reliability are essential.

CenterPoint stated it “appreciates the Commission’s continued focus on energy affordability for all Hoosiers,” highlighting efforts to stabilize rates. Indiana Michigan Power also noted that it “know(s) Hoosiers are worried about rising energy costs,” and recently filed to reduce its base rates.

The inquiry will take place on March 24 at the PNC Center in Indianapolis. Depending on the results, the IURC may take informal or formal actions.

Chairman Zay also announced a statewide tour to gather feedback directly from residents. Lawmakers said the findings may guide future legislation, with proposals already being considered to address rate stability and consumer protections.
