NIPSCO electric rates and bills

NIPSCO's 433,889 residential customers in Indiana paid an average of 22.05¢ per kWh in 2025, for an average bill of $148.15 a month on 672 kWh.1 Over the last 12 months (Sep 2025–Aug 2026) the average was 23.60¢, and 23.43¢ in August 2026.2

EIA-861 2025 final (released October 7, 2026) and EIA's monthly utility survey through August 2026 (preliminary); next monthly update expected November 24, 2026. Averages are revenue divided by kWh, all charges included: not the rate printed in a tariff.

20 of 92 Indiana counties served (EIA-861 2025)

NIPSCO's residential customers paid an average of 22.05¢ per kWh in 2025, the highest of Indiana's 32 larger utilities and 38.2% above the Indiana average, and 23.60¢ per kWh2 over the 12 months to August 2026. Its homes use little electricity, so the average bill stays close to the state's, while its industrial customers paid 6.98¢ per kWh1.

The highest residential average in Indiana

Northern Indiana Public Service Company (NIPSCO) serves 433,889 residential customers across the northern part of the state. In 2025 they paid 22.05¢ per kWh on average, the highest among the 32 Indiana utilities with 10,000 or more residential customers. The Indiana average across all providers was 15.96¢ per kWh3, so NIPSCO's homes paid 38.2% above the Indiana average. Nationally the figure ranked 23rd highest of 177 large utilities and was 24.0% above the national average for investor-owned utilities1.

That price is average revenue per kWh: everything NIPSCO billed its homes, including the monthly customer charge and the fuel and other adjustment trackers, divided by the kWh they used. Most taxes are left out. No single line on a NIPSCO bill shows it, and a household that uses little pays more per kWh than the average, because the fixed charge is spread over fewer kWh.

The gap to the next utility is large. CenterPoint Energy Indiana South, in the southwest, averaged 19.78¢ per kWh in 2025; Indiana Michigan Power, which also serves part of northern Indiana, 17.16¢ per kWh; Duke Energy Indiana 14.98¢ per kWh; and AES Indiana 14.69¢ per kWh1. NIPSCO was still the highest of the five in the monthly survey for August 2026: 23.43¢ per kWh2, against 17.02¢ per kWh4 for Indiana as a whole (both preliminary).

The 2025 increase and the rate case behind it

NIPSCO's residential average rose 15.5% between 2024 and 2025, from 19.09¢ per kWh to 22.05¢ per kWh. Statewide, the residential average rose 8.1%3 over the same two years. Because use per home also edged up, from 659 kWh to 672 kWh a month, the average bill rose more than the price: from $125.775 to $148.15 (+17.8%1).

The rise came in the year NIPSCO's electric base-rate case was decided. According to the Indiana Office of Utility Consumer Counselor, NIPSCO filed the case on September 12, 2024, and the Indiana Utility Regulatory Commission approved a settlement on June 26, 2025; the settlement kept the monthly residential customer charge at its existing amount. Trackers for fuel and other costs are adjusted outside base-rate cases, which is why the average can change in a year without a new base-rate order. The guide to rate increases explains how such decisions reach a bill.

EIA's monthly survey (EIA-861M) puts the last 12 months (September 2025 to August 2026) at 23.60¢ per kWh, above the 2025 average; 2026 months are preliminary. In August 20264 the residential average was 23.43¢ per kWh, +3.0% on August 2025. For the same month Duke Energy Indiana's average changed by +8.6% and AES Indiana's by +9.6%2, so in that month the other two averages rose faster than NIPSCO's, though from much lower levels. EIA's next monthly release, on November 24, 2026, adds September 2026.

Low use keeps the bill near the state average

NIPSCO's homes used 672 kWh a month on average in 2025, the least among Indiana's large utilities and well under the Indiana figure of 938 kWh6. Duke Energy Indiana's homes used 992 kWh, AES Indiana's 941 kWh1.

The result is a bill in line with the rest of the state despite the price. In 2025 the average NIPSCO bill was $148.151 a month, against $149.72 across Indiana and $150.686 for the US. Over the last 12 months (September 2025 to August 2026) NIPSCO's homes used 650 kWh a month and the average bill was $153.412. The arithmetic also works in reverse: a NIPSCO household that uses as much as the Indiana average would pay more than at Duke or AES at their average prices, because each kWh costs more.

July is the costly month

Over the last 12 months, use per home was highest in July 2026, at 1,022 kWh and an average bill of $227.14, and lowest in April 2026, at 486 kWh and $114.99. Duke Energy Indiana and AES Indiana peaked in January 20262 instead.

Homes pay about three times what industry pays

NIPSCO's price structure is unusual within Indiana. Its 2,117 industrial accounts paid 6.98¢ per kWh on average in 2025, the lowest industrial average of the five investor-owned utilities: Duke Energy Indiana's industrial customers paid 8.64¢ per kWh, Indiana Michigan Power's 8.89¢ per kWh, CenterPoint's 9.65¢ per kWh and AES Indiana's 11.21¢ per kWh. Its homes, at 22.05¢ per kWh1, paid the highest.

Commercial customers sat between the two. NIPSCO's 60,535 commercial accounts paid 19.24¢ per kWh on average, with a monthly bill of $1,006.22; at AES Indiana the commercial average was 15.57¢ per kWh and at Duke Energy Indiana 11.75¢ per kWh. Across all 496,542 accounts, NIPSCO's average was 13.33¢ per kWh1, pulled down by the large volumes sold to industry at the lower price. Industrial customers usually take power at higher voltage and in large, steady amounts, so their averages are lower almost everywhere; the width of the gap differs from one utility to the next.

Territory: northern Indiana, county lines shared

EIA's service-territory records list NIPSCO in 20 counties, from Lake and LaPorte on Lake Michigan east to Elkhart, LaGrange and DeKalb and south to Benton and Carroll. In all 207 at least one other distribution utility also reports customers, such as a rural electric membership corporation or a city-owned utility. A county or ZIP code therefore does not settle which utility serves an address; NIPSCO's own service map decides by street, and EIA publishes no city prices. Indiana's cooperatives together averaged 14.98¢ per kWh for homes in 2025 and its public power utilities 11.96¢ per kWh1.

Lake County, at the western end of NIPSCO's territory, borders Illinois and the Chicago area, where ComEd delivers electricity in Illinois. The two averages measure different things: ComEd's 2025 figure of 17.71¢ per kWh covers only its default-service customers, because Illinois households may buy supply from a retail supplier, while NIPSCO's covers all its homes. In Indiana there is no such choice (0.0% of residential customers bought from a supplier in 2025), and NIPSCO sells power in the MISO1 wholesale market.

No smart meters reported, and long outages in 2025

NIPSCO reported 0.0% of its residential meters as advanced (AMI) meters to EIA for 2025, against 81.6%9 statewide; Duke Energy Indiana, AES Indiana, Indiana Michigan Power and CenterPoint all reported close to full coverage. Advanced meters record use by the hour and are what time-of-use billing relies on. Whatever optional rates NIPSCO offers are set out in its tariff, which EIA does not publish; the time-of-use guide explains how such rates change a bill.

Rooftop solar is rare: 1,414 residential net-metered installations with 13.0 megawatts of capacity, 3.3 per 1,000 customers, against 3.79 per 1,000 across Indiana.

Under the IEEE 1366 standard, NIPSCO's customers averaged 532 minutes without power in 2025 including major event days, more than the Indiana average of 345 minutes. On ordinary days the gap was smaller: 178 minutes excluding major events, against 125 minutes for the state. The number of interruptions was close to the Indiana figure (1.32 per customer, against 1.3810), so the 2025 total came from longer outages rather than more frequent ones. A single stormy year can move these figures widely.

Help with bills

Indiana's federal home energy assistance (LIHEAP) allocation was $87.1 million for fiscal year 2026, and $75.9 million11 in the first release of fiscal year 2027 funds, a partial amount. The state program covers NIPSCO customers like any other household in Indiana. For the statewide picture, see electricity in Indiana.

NIPSCO rates: common questions

What is NIPSCO's electric rate per kWh?

On average, residential customers paid 23.60¢ per kWh2 over the last 12 months (September 2025 to August 2026, 2026 months preliminary) and 22.05¢ per kWh1 in calendar 2025. These are total residential revenue divided by kWh sold, so the monthly customer charge, fuel and other trackers are included; the energy charge printed in NIPSCO's tariff is a narrower number.

What is the average NIPSCO electric bill?

$148.15 a month in 2025 for 672 kWh1, and $153.41 over the last 12 months (September 2025 to August 2026). July is the most expensive month: in July 2026 the average reached $227.142.

Did NIPSCO's electric rates go up in 2026?

The average price is still above its 2025 level. Over the last 12 months (September 2025 to August 2026) it was 23.60¢ per kWh, against 22.05¢ per kWh1 for 2025, and in August 20264 it was 23.43¢ per kWh, +3.0%2 on August 2025 (preliminary). Base-rate changes are decided by the Indiana Utility Regulatory Commission.

Can I buy electricity from someone other than NIPSCO?

No. Indiana has no residential retail choice: 0.0%1 of the state's residential customers bought from a competitive supplier in 2025. NIPSCO supplies every home on its lines.
