Vinny is frustrated. He tried calling. He tried visiting. He got nothing. This one's for him.

‍

The Building on 86th Avenue

‍

The NIPSCO headquarters is at 801 E. 86th Avenue, Merrillville, Indiana. You probably drive past it. It's a real building with a real address and presumably real people inside, though you would be forgiven for questioning that last part.

‍

The NiSource website, NiSource being the parent company that owns NIPSCO, because of course there's a parent company, lists the address and adds the following note in plain text, "Please note: The locations below are not customer service centers or authorized payment locations."

‍

So. You can go there. You just can't do anything once you arrive.

‍

This is the building where decisions get made about your rate. This is where the GenCo strategy was developed. This is where someone decided that charging the second-highest residential electric rate of any utility reporting data to the federal government was a reasonable outcome for the customers of northern Indiana. The lights are on inside. The parking lot has cars. But if Tim from this series drives up and pushes the button at the front door because his bill doubled and he can't get anyone on the phone, well. Tim is going to be standing outside for a while.

‍

To be fair, this is not unique to NIPSCO. Most large utilities have moved away from walk-in customer service. The industry trend is digital-first, call center-second, in-person-never. NIPSCO is following the playbook.

‍

It is still deeply funny that the company billing you the highest electric rates in Indiana cannot be reached by walking to their headquarters fifteen minutes from most of Northwest Indiana.

‍

The Phone Menu That Runs Your Life

‍

You need help with your NIPSCO bill. Okay. Here are your options.

‍

You can call 1-800-464-7726. That is the main number. You will be greeted by an automated system. The system will ask for your account number or phone number. If you want to reach a human, the documented trick is to press 1, then 0#, each time it asks for account information. This information was discovered and published not by NIPSCO, but by a third-party service whose entire business model is helping people navigate corporate phone trees.

‍

You can also call 1-800-634-3524 for general customer service, or 1-844-809-8921 if you are an existing customer. There is also a TDD/TTY number: 1-800-635-0952. There is a live chat option, available 11am to 3pm, Tuesday through Friday only. Four hours a day, four days a week. Plan accordingly.

‍

The average hold time, per third-party analysis, is somewhere between three minutes and, if you've hit a Tuesday, which is the busiest day, considerably longer. One BBB complaint documented a wait time of 45 minutes to an hour, followed by a callback that came an hour after that, followed by being put back on hold for another 30 minutes before hanging up. Total time invested to resolve a furnace emergency in winter: multiple hours across multiple days. Outcome: unresolved.

‍

Third-party services have emerged specifically to call NIPSCO for you, wait on hold for you, navigate the menu for you, and report back. There is a market for this. The market exists because talking to NIPSCO is unpleasant enough that people will pay someone else to do it. That is the state of customer service at the company charging you the highest electric rates in the state.

‍

To their credit, NIPSCO's phone line is available 24 hours a day, 7 days a week, for emergencies. Gas leaks, power outages, you can call at 3am. That is good. That is what a utility is supposed to do.

‍

For everything else, billing questions, rate explanations, meter disputes, complaints about why your delivery charge is higher than your actual gas usage, you are in the queue. Bring a snack.

‍

The Bill You Didn't Understand and the Explanation You Never Got

‍

Let's talk about what you are calling about.

‍

NIPSCO customers using 1,000 kilowatt-hours in July 2025 reportedly saw more than a 90% increase in their electric bill compared to 2016. That's not a typo. Ninety percent. In nine years. On the same amount of electricity.

‍

Some customers opened their bills in late 2024 and early 2025 to find charges double or triple what they'd paid the prior year. One customer told the BBB their July 2024 bill was $308; their July 2025 bill was $450, and NIPSCO had publicly announced "up to 20%" increases. The math did not match the announcement. The company explained this, eventually, to those who could get someone on the phone.

‍

A significant number of customers noticed their delivery charges, the fees NIPSCO charges to operate and maintain the infrastructure that brings gas to your home, exceeded their actual gas charges. This surprised many people because nobody had explained what a delivery charge was, what it covered, or why it had grown so substantially. When NIPSCO was asked whether they had ever proactively reached out to explain delivery charges to customers, the answer was a careful rephrase: customers can visit NIPSCO.com or reach out directly for support.

‍

In other words: NO.

‍

Then there is the meter situation.

‍

The Meter Investigation Nobody Told You About

‍

In November 2025, the Indiana Utility Regulatory Commission opened a formal investigation into NIPSCO's natural gas billing. The investigation was triggered by NIPSCO's own disclosure that during the rollout of new smart meter technology, installed on 870,000 gas meters across northern Indiana, there were billing errors on a "not-insignificant number" of meters.

‍

The IURC's General Counsel, in a letter to the Chief Administrative Law Judge, noted that NIPSCO had discovered the errors, quietly issued bill credits to affected customers, and did not proactively provide notice or explanation to those customers that anything had gone wrong.

‍

Read that again. NIPSCO found billing errors. NIPSCO issued credits. NIPSCO did not tell the customers who had been overbilled that they had been overbilled, why the error occurred, or how the credit had been calculated. The customers received credits on their bills that they presumably assumed were some kind of promotional adjustment, because nobody told them anything.

‍

The IURC had to open a formal investigation to find out the scope of the problem. As of early 2026, NIPSCO was required to file testimony and evidence by March 2, the state consumer advocate office would respond by May 21, and a hearing was scheduled for July. Somewhere in that timeline, the full picture of who was overbilled, by how much, and for how long will emerge. Or it won't, and the process will extend further.

‍

NIPSCO's official statement: safety and accurate billing are top priorities. The company is cooperating fully.

‍

This is the company you call when your bill doubles. This is the company you drive to on 86th Avenue when you can't get anyone on the phone. This is the company that found an error on a not-insignificant number of meters, corrected it quietly, and waited for regulators to discover that customers hadn't been told.

‍

✉️ NIPSCO won't help you lower your bill. We will.

What "Customer Service" Looks Like From a Monopoly's Perspective

‍

Here is the thing about being a monopoly regulated utility, your customers cannot leave.

‍

If your internet provider frustrates you, you switch providers. If your insurance company ignores your calls, you find another insurer. Competition is the mechanism that forces companies to care about service, because bad service costs them customers and customers cost them revenue.

‍

NIPSCO has no such mechanism. You are in northern Indiana. NIPSCO serves northern Indiana. If you want gas and electric service in northern Indiana, you are a NIPSCO customer. There is no alternative. You cannot switch. The entire structure of regulated utilities is premised on a tradeoff, you give up competition in exchange for rate regulation by the IURC, which is supposed to prevent the monopoly from exploiting its position.

‍

The problem with that tradeoff, as this series has documented at some length, is that rate regulation is slow, technical, and dominated by parties with more resources than the average ratepayer. NIPSCO has lawyers and lobbyists and a parent company in NiSource that manages seven regulated utilities across seven states. The individual residential customer has a phone that nobody is answering on a Tuesday.

‍

An Indiana state representative recently wrote to the IURC calling for a review of NIPSCO rates, citing constituent concerns and noting that NIPSCO customers had absorbed the largest rate increase among all IURC-regulated electric utilities over the past decade. A bill focused on increasing energy affordability and holding utilities more accountable has been working its way through the state legislature. These are good developments. They are also slow-moving legislative processes that will play out over years while your bill arrives every month.

‍

The NIPSCO president gave an interview in January 2026 addressing customer concerns about rising bills. He explained that cold winters mean furnaces run longer. He explained that natural gas prices increased nationwide. He explained the delivery charge. These are real explanations. They are also explanations that customers have been asking for, via phone and email and presumably buzzer at 801 E. 86th Avenue, for quite some time.

‍

The Honest Summary

‍

NIPSCO is not a villain. It is a utility company operating in a system that was designed exactly the way it operates: as a regulated monopoly, with slow-moving oversight, incentivized to build infrastructure and earn a return on capital, and structurally insulated from the market pressure that normally disciplines bad customer service.

‍

The billing investigation, the rate increases, the phone tree, the buzzer at the front door, none of this is the product of individual malice. It is the product of a system where accountability moves at IURC speed and the bills arrive on a monthly cycle.

‍

Understanding this does not make your bill smaller. It does not make the hold music more tolerable. It does not explain why your delivery charge exceeded your gas usage or why nobody called to say your meter might have had an error.

‍

What it tells you is that the mechanism for changing your situation is not a phone call to NIPSCO. It is not a visit to 86th Avenue. It is not a BBB complaint or an email to nipscoquestions@nisource.com. Those things have their place, but none of them lower your bill in any meaningful, durable way.

‍

The mechanism is reducing how much you buy from them.

‍

Questions You'd Ask If Anyone Would Pick Up

‍

Q: Can I actually walk into NIPSCO headquarters and talk to someone?

A: Technically yes. Practically, no. The address is 801 E. 86th Avenue, Merrillville. NiSource's own website notes it is "not a customer service center or authorized payment location." There is a buzzer. What happens after you push it depends on the day.

‍

Q: What's the best way to reach a real human at NIPSCO?

A: Call 1-800-464-7726. Press 1, then 0# every time it asks for your account number. Friday is the least busy day. Tuesday is the worst. Live chat exists — 11am to 3pm, Tuesday through Friday only. Four hours a day, four days a week.

‍

Q: My bill doubled. Is that normal?

A: NIPSCO customers using 1,000 kWh in July 2025 saw over 90% higher bills compared to 2016, on the same amount of electricity. Some of that is rate increases. Some of it may be meter errors currently under state investigation. Some of it is delivery charges that were never clearly explained. All three things can be true at once.

‍

Q: What's the meter investigation about?

A: In November 2025, the IURC opened a formal investigation after NIPSCO disclosed billing errors affecting a "not-insignificant number" of its 870,000 gas meters. NIPSCO found the errors, quietly issued credits to affected customers, and did not tell those customers anything was wrong. Regulators found out anyway. A hearing is scheduled for July 2026.

‍

Q: What is a delivery charge and why is it sometimes bigger than my gas charge?

A: The delivery charge covers the infrastructure NIPSCO maintains to move gas to your building, pipes, maintenance, emergency response, operating costs. It is a fixed cost regardless of how much gas you actually use. When gas usage is low and infrastructure costs are high, the delivery charge can exceed the commodity charge. NIPSCO has not historically been proactive about explaining this on your bill.

‍

Q: Can I complain to anyone who actually has authority over NIPSCO?

A: Yes. The Indiana Utility Regulatory Commission (IURC) regulates NIPSCO and accepts complaints. The Indiana Office of Utility Consumer Counselor (OUCC) advocates for ratepayers in IURC proceedings, they are currently involved in the meter investigation. State legislators have also recently called for a rate review. None of these move fast, but they are the legitimate channels.

‍

Q: Is there anything I can do right now to lower my bill without waiting for regulators?

A: Yes. Reduce how much you buy from them. Insulation and air sealing lower your load directly. Solar plus battery storage lets you generate and store your own electricity, putting a portion of your consumption permanently outside NIPSCO's rate structure. That's what this entire series has been building toward.

‍

What You Can Actually Do About It

‍

This series has covered ten articles. The arc is simple.

‍

Articles one through five, your building loses energy in predictable ways, and you can stop that with insulation, air sealing, and building envelope work. When your load drops, your bill drops. NIPSCO doesn't have to cooperate for that to work.

‍

Articles six through ten: the grid is getting more expensive, more complicated, and more loaded with industrial demand. The structure that is supposed to protect you, regulatory oversight, rate cases, the GenCo framework, has real skeptics and a long track record of NIPSCO getting what it asks for. On-site solar plus battery storage puts you outside the rate case for the fraction of your energy you generate and store yourself. That fraction doesn't get a delivery charge. It doesn't have a meter investigation. It doesn't require you to press 1, then 0#, every time you have a question.

‍

You still need NIPSCO. Your building is still connected to the grid, and should be, total energy independence is not practical for most commercial buildings and not the goal of this program. The goal is reducing exposure. Every kilowatt-hour you generate and consume yourself is one that arrives without a phone tree, without a delivery charge markup, and without a rate case that took two years to resolve.

‍

NIPSCO's website says they are here to help, 24 hours a day, seven days a week.

‍

So are we. Except we pick up.
