NIPSCO is proposing $57.5 million in bill credits for its existing electric customers, drawn from the value of its data center deals. The average residential customer would see “a monthly bill credit of approximately $5 for 18 months,” about $90 in total, according to the company’s Oct. 28 announcement. The credit is “subject to regulatory approval,” and it would begin about 30 days after that approval.
For a northern Indiana household, the open question is whether and when the $5 a month shows up. Nothing has started yet. NiSource has not published an approval date or a filing number, and $5 is an average for residential customers, not a promise for every account.

Where does the $57.5 million come from?
NiSource, NIPSCO’s parent, says the new credit “builds on $1.75 billion in customer credits” expected from previously announced agreements with Amazon, Alphabet and Microsoft. Under those deals, the company says, large-load customers fund the infrastructure needed to serve them, and a portion of the revenue from their contracts is returned to other customers. Those earlier credits are expected to begin in the first quarter of 2027 and ramp up over time.
“When our region grows, our customers share in the benefits,” said Vince Parisi, NIPSCO’s president and chief operating officer. He described putting data center value “directly back on customers’ bills” as a way of turning growth into savings.
Why is the money tied to a subsidiary?
The structure behind it is NIPSCO Generation, known as GenCo, a NiSource affiliate set up to own and run power plants for data centers and other large customers. In a Sept. 24, 2025 release, NiSource said the Indiana Utility Regulatory Commission had approved the GenCo arrangement, which is meant to “shield NIPSCO’s existing retail customers from costs associated with serving new data center customers.”
NiSource chief executive Lloyd Yates said at the time that the order “reflects confidence in our ability to deliver safe, reliable and affordable energy solutions.” The $57.5 million is a separate step from that approval, and it still needs its own regulatory sign-off before any customer sees a credit.
How does this compare with the Amazon deal’s promise?
Utility Dive reported in November 2025 that the 15-year Amazon agreement was expected to produce about $1 billion in savings for ratepayers, shown as a credit on electric bills, with residential customers getting roughly $7 a month. GenCo plans up to 3 gigawatts of gas-fired generation and battery storage for Amazon, with deliveries starting by Jan. 1, 2027 and rising to 2.4 gigawatts by the end of 2032. Amazon also holds a one-time option, by March 31, 2029, to cut its total capacity by 1,200 megawatts, which could change how much load the deal carries.
The $90 figure is therefore a different, smaller layer. A customer could eventually see the Amazon-era credits that begin in 2027 and the 18-month credit proposed now.
Utility Dive also reported that the framework is built so existing customers do not pay for infrastructure needed to serve hyperscalers like Amazon, and that transmission costs will be kept separate from NIPSCO’s rate base and will not flow through to existing customers. GenCo plans to seek separate commission approval for any generation it builds for Amazon.
What do critics say about the data center deals?
Not everyone is convinced the arrangement protects households. Ben Inskeep, program director at the Citizens Action Coalition, said in November 2025 that the group would “vigorously advocate to protect residential customers from risks.” He also called it “outrageous” that none of the electricity serving the 2.4 gigawatts of data center load would come from additional renewable energy or energy efficiency.
The Amazon agreement also still needs approvals. Utility Dive reported that the Federal Energy Regulatory Commission must approve the power purchase agreement, and that the companies asked the Indiana commission to approve a special contract and the agreement by May 6.
The $1.75 billion total is where the larger numbers live. The new $57.5 million is equal to about 3 percent of that earlier figure, and it is added on top of it. NiSource’s release calls the earlier credits “expected,” and says customers can expect the first of them in the first quarter of 2027, ramping up over time.
Parisi, who is also the NIPSCO executive that Utility Dive says described the Amazon delivery schedule in a filing with the Indiana commission, is the named face of both announcements. No other NIPSCO or NiSource official is quoted in the new release about how the credit would be calculated for different customers.
What should a customer do while the credit is pending?
Nothing in the announcement asks customers to sign up, and no application is described. The credit would appear on the electric bill itself, so the monthly statement is the place to look once regulators act. A credit of about $5 is small next to a winter heating bill, which makes the rest of the bill the bigger lever.
Will a $5 monthly credit make a dent in your NIPSCO bill?
A credit that is still waiting on regulators does nothing for the bill due this month. At about $90 spread over 18 months, it is a small cushion, and the rest of the electric bill is where a call can still change the number.
