My name is Eric Knorr. I am a homeowner and ratepayer in Dyer, Indiana, in the NIPSCO service territory. I am writing this as an open letter because what is happening to electric bills in northern Indiana is not a personal grievance — it is a documented pattern affecting hundreds of thousands of captive customers, and the public record raises legitimate questions about whether the oversight system is functioning as intended.

Everything in this letter is sourced. I have attached a full citation appendix. I am not asking anyone to take my word for it.

Part I

The Numbers

I have eight years of actual billing records from my NIPSCO account — 102 consecutive monthly reads. My effective cost per kilowatt-hour, calculated directly from those bills, increased from approximately 13.9 cents in 2018 to 22.7 cents in 2026.

NIPSCO's residential bill increase from 2016 to 2025: $121.86 → $233.62. No other Indiana jurisdictional utility came close. Next-highest: CenterPoint at 42.37%.

The Indiana Utility Regulatory Commission's own 2025 Electricity Residential Bill Survey — a primary government document — provides independent corroboration. NIPSCO ranked last among all nine Indiana jurisdictional utilities at $233.62 per 1,000 kWh as of July 1, 2025. The IOU average across all five investor-owned Indiana utilities was $187.00. NIPSCO's bill was 24.9% above that average.

The U.S. Energy Information Administration has separately reported that NIPSCO had the second-highest residential customer rate among all electric utilities reporting data nationally. This is not a regional affordability problem. It is a NIPSCO-specific problem.

Part II

The 2025 Rate Case

In July 2025, the IURC approved a new NIPSCO electric rate increase phased in through Q1 2026. The settlement authorized an increase of approximately $23/month for the average residential customer using 672 kWh/month — a 16.75% increase. NIPSCO's original request had been $32/month.

The Citizens Action Coalition opposed the settlement. Their analysis found that an average residential customer using 729 kWh/month saw monthly bills rise from $136.53 in September 2024 to $171.27 by March 2026 — a 25.45% increase in 18 months. The settlement also eliminated a Low-Income Multi-Family Rate that NIPSCO had originally proposed and CAC had supported. Large commercial and industrial customers received proportionally smaller increases than residential customers.

+28% year-over-year

The rate is rising faster than I can reduce consumption.

Part III

The Regulatory Structure and Its Limitations

Indiana's electric market is fully regulated. NIPSCO holds a state-sanctioned monopoly in northern Indiana. Residential customers in Dyer, Highland, Hammond, and surrounding communities have no ability to choose an alternative electric provider. The IURC is the sole institutional check on NIPSCO's pricing — which makes the integrity of that commission a matter of direct material consequence to every ratepayer it serves.

Commissioner David Ziegner has served on the IURC since 1990 — 36 years — receiving continuous reappointments from governors of both parties. During his entire tenure, the commission has approved every NIPSCO rate increase brought before it. Commissioner Ziegner serves on the Board of Directors of NARUC — the National Association of Regulatory Utility Commissioners — an organization that includes active engagement from the same investor-owned utilities its member commissioners regulate. Scholars and practitioners of utility regulation commonly refer to the institutional risk that arises when a regulator's professional identity and career become intertwined with the regulated industry over decades as 'regulatory capture.' Whether that characterization applies here is a judgment I leave to others. What is not a matter of interpretation is the 36-year tenure, the NARUC board seat, and the 91.71% rate increase that occurred on this commission's watch.

"The balance between customers and providers feels dramatically out of whack right now for many, many Hoosiers."
— IURC Chair Andy Zay, February 2026 affordability hearings

Commissioner Anthony Swinger brings a different institutional background: 25 years at the Indiana Office of Utility Consumer Counselor, the state agency that advocates for ratepayers in commission proceedings. His appointment is meaningful. At the March 2026 IURC affordability hearings, Commissioner Swinger pressed NIPSCO directly on its consumer complaint volume, documenting that more than half of all statewide IURC consumer affairs complaints were about NIPSCO alone — and that year-to-date complaint volume had already matched all 12 months of 2025. That is the kind of adversarial scrutiny ratepayers need from this body.

To Chair Zay and the full commission: the February 2026 affordability investigation was a necessary step. The question now is what the investigation produces. Indiana ratepayers need to see specific, enforceable outcomes — not findings that NIPSCO is invited to address on its own timeline.

Part IV

Financial Relationships Between NIPSCO/NiSource and Public Officials

The following are documented facts drawn from FEC filings, NiSource's own public disclosures, and Indiana campaign finance records. I am placing them in this letter because they are relevant to a full understanding of the regulatory environment that produced the rate outcomes described above. I am not asserting that any contribution influenced any decision. I am asserting that the public has a right to know these relationships exist.

A. Federal Campaign Contributions — NiSource PAC (2023–2024 Cycle) · FEC filings via OpenSecrets.org
Rep. Frank J. Mrvan (D, IN-1) — recipient of this letter $10,000
Rep. Greg Pence (R-IN) $2,000
Rep. Rudy Yakym (R-IN) $2,000
Rep. Andre Carson (D-IN) $1,000
Editorial correction note The $10,000 contribution to Rep. Mrvan is among the largest — not the sole largest — NiSource PAC contribution to any member of Congress in the 2023–24 cycle. Rep. Reschenthaler (R-PA) also received $10,000. Characterization in this letter reflects that tie.
B. Federal Lobbying & Governors Association Contributions (2024) · NiSource Political Engagement Disclosure
Total U.S. lobbying expenditures (Lobby Disclosure Act) $500,000
Republican Governors Association $105,000
Democratic Governors Association $155,000
Total governors association contributions (corporate funds) $260,000

The governor of Indiana appoints all five IURC commissioners. NiSource contributed to both governors associations in 2024. Note: PAC contributions are employee-funded; governors association contributions are corporate funds — a distinction worth drawing clearly.

C. State Legislative Contributions (2025–2026 Cycle) · PanoramaNOW citing Indiana Transparency USA
Indiana state-level PAC contributions (reported total) $80,000+
Rep. Ed Soliday (R-Valparaiso) — chair, House Utilities & Energy Committee; co-author, HB 1333 Named recipient

Indiana has no statutory limits on PAC contributions to state legislative candidates. This is a matter of law, not a claim against any individual.

D.

The Blackstone Transaction, GenCo, and the Regulatory Exemption

In June 2023, NiSource sold a 19.9% equity stake in NIPSCO Holdings II to Blackstone Infrastructure Partners for $2.15 billion. Following this transaction, the IURC approved a declination petition for NiSource's newly created NIPSCO Generation LLC (GenCo) in September 2025. That approval exempted GenCo from the standard requirement to file a detailed plan before building or acquiring new generation facilities — the Public Convenience and Necessity process that applies to the regulated utility.

GenCo is designed to build and own power plants serving Amazon and other data center customers in northern Indiana. The Citizens Action Coalition and the Indiana Office of Utility Consumer Counselor both filed notices of intent to appeal the GenCo approval. CAC Executive Director Kerwin Olson has stated publicly that if GenCo were to lose money, those losses could affect NiSource's credit rating and, in turn, impact NIPSCO's residential customers — and that some infrastructure costs could still reach residential ratepayers through the opaque process created for GenCo. This is not speculation. It is the documented concern of the state's own ratepayer advocacy office.

E.

Wall Street's Assessment of the IURC

The departing commissioners were "heavily involved in industry stakeholder engagement, including at NARUC, and known favorably by investors." Their departure was "a clear negative development for NiSource."
— Jefferies equity analysts, investor note, September 2025 (via Utility Dive)

This assessment came from the financial industry — from analysts whose job is to evaluate risk to NiSource shareholders. Their characterization of those commissioners as favorable to investor interests, and their departure as bad for NiSource, is relevant context for evaluating the commission's historical posture toward rate cases.

Part V

What I Am Asking For

1

Legislate a rate rollback or rate cap referenced to the national average

NIPSCO's residential rate is 33% above the national average and 91.71% above its own 2016 level, per IURC survey data. I am asking the Indiana General Assembly to pass legislation requiring NIPSCO to bring its residential electric rate in line with the national average of 17.0¢/kWh, or to freeze rates at pre-2022 levels while an independent audit of NIPSCO's cost structure is completed. NiSource reported $760 million in net income in 2024. The company is not in financial distress.

2

Open Indiana's NIPSCO territory to retail electric competition

Residential customers in NIPSCO territory have no electric supplier choice. Ohio, Illinois, and Pennsylvania have deregulated electricity markets where customers can shop for competitive rates. The most direct remedy for ratepayers is the ability to choose. Regulated monopoly pricing, as the 10-year IURC survey data demonstrates, has not constrained NIPSCO's rate trajectory.

3

Commission an independent forensic audit of NIPSCO's rate base

NIPSCO has filed three rate cases in rapid succession — 2022, 2023, and 2024–2025 — each justified by prior capital investments approved in earlier proceedings. This creates a self-reinforcing recovery cycle. I am asking for an independent audit, conducted by an entity with no financial relationship to NiSource, its affiliates, or any firm that regularly appears before the IURC, to determine whether ratepayers are receiving value proportionate to the rates they are paying.

4

Enact revolving-door restrictions and contribution transparency requirements

Indiana currently has no post-service restrictions on IURC commissioners entering utility-adjacent employment, and no statutory limits on utility PAC contributions to the legislators who write utility law. Texas enacted revolving-door restrictions for its Public Utility Commission. Indiana should establish a minimum two-year cooling-off period before former IURC commissioners may work for, consult for, or accept compensation from any entity that appeared before the commission during their tenure. The legislature should also require real-time, bill-specific disclosure of all utility lobbying activity at the Statehouse.

5

Formally review the GenCo regulatory exemption

The IURC's decision to exempt GenCo from standard Public Convenience and Necessity requirements creates a category of NiSource generation assets that will serve large commercial customers outside the normal transparency process, while sharing the parent company's balance sheet with residential ratepayers. I am asking the General Assembly and the IURC to formally review whether that exemption adequately protects existing NIPSCO customers from financial risks associated with the Blackstone transaction and GenCo's data center obligations.

This letter is on the public record. Every figure in it is sourced to a primary document. Every financial relationship described is legally disclosed. I have not alleged crimes or improper conduct. I have assembled documented facts about rates, regulatory outcomes, and financial relationships — and I have asked elected officials to act on them.

NIPSCO's 91.71% rate increase since 2016 — the largest of any Indiana jurisdictional utility, per the IURC's own survey — did not happen in a vacuum. The financial relationships documented in Part IV are part of the public record. Whether they constitute a problem is a question I leave to the legislators, regulators, and journalists who receive this letter. What I am asking is that the question be asked, openly, with the same access to primary sources that I have provided here.

I expect a written response from State Sen. Dan Dernulc, State Rep. Hal Slager, Rep. Frank Mrvan, Sen. Jim Banks, and Sen. Todd Young. I am also asking Chair Zay and the full commission to address, in the current affordability proceeding, the specific questions of rate rollback authority and GenCo's implications for residential ratepayers.
