Why a Duke Energy Indiana bill moved
The price change was the larger piece
Hold a Duke Energy Indiana household to the filing average and the monthly full service bill changed +23.5% between those two EIA years. Holding the 2024 price fixed, the usage change of +5.2% is worth $6.20 a month. The price change of +17.5%, from 12.75¢ to 14.98¢, is worth $22.09 on 2025 usage.
Below the Indiana average
14.98¢ per kWh is below Indiana's 2025 residential average of 15.96¢. July 2026 in the state was 16.73¢, versus 16.18¢ a year earlier (+3.4%). The utility figure is a full year of average revenue. The state figure is one later month. A household that uses more than 992 kWh will not land on $148.57.
One full-service average
808,572 residential customers were on Duke Energy Indiana full service in 2025, at 14.98¢ per kWh. That average folds in the customer charge and whatever riders the utility booked as residential revenue. It is not the last block on a tiered tariff.
Season
The 2025 monthly average for this Duke Energy Indiana service was 992 kWh, and the Indiana residential average was 938 kWh. A single month can sit far from either figure. Compare kilowatt-hours with the same month last year before you treat the whole increase as a rate hike.
Time-of-use is already on the EIA schedule
EIA's 2025 dynamic-pricing file shows residential time-of-use activity at Duke Energy Indiana, with 73 residential customers enrolled in dynamic pricing. The expensive window is in the tariff, not in that enrollment count. Shifting a dishwasher or an EV charger only helps if you are actually on that schedule.

How to lower the bill
- Read the kilowatt-hours against this filing's average of 992 kWh a month. If your use is the thing that moved, the dollar total can rise on an unchanged rate.
- On the statement, separate the base energy charge from fuel or rider lines. A rider can move the total in a month when no new base-rate order exists.
- Match this month's weather to last year's same month. A mild comparison month makes an ordinary bill look like a hike.
- Start with LIHEAP for Indiana (https://www.acf.hhs.gov/ocs/map/liheap-map-state-and-territory-contact-listing). A Duke Energy Indiana discount beyond that program needs verification.
- 73 residential customers were already on a dynamic price in the 2025 EIA file. If you are one of them, the window on the tariff is the lever. If you are not, calling the utility to discuss the schedule is the first step, not shifting load you are not being charged extra for.
- If the read is marked estimated, the next actual read can true the account up or down. The tariff rule for that true-up needs verification.

LIHEAP is the federal program for home energy bills (https://www.acf.hhs.gov/ocs/programs/liheap). Duke Energy Indiana may also offer an income-qualified discount, budget billing, or a medical baseline. The current offer, income cutoff, and how to apply need verification on the utility site and with the state LIHEAP office and Indiana Utility Regulatory Commission.
Are data centers why this bill went up?
Large computing load is raising U.S. electricity demand, and regulators can later recover new generation and wires costs from customers. EIA has not published a dollar line that isolates data centers on this utility's residential bill. That pass-through needs verification.
