Installers serving Duke Indiana customers

Pick one. Only the company you choose receives your details, and only that company calls you.

Not sure which to choose?

These are real companies operating in Duke Indiana territory. Bold Energy is listed first because it is the company we introduce first. That order is our choice, not a score. The other companies are ordered by reviews, years trading and BBB grade. None of them pays us for placement. Pick the one you want and we will call you to arrange it.

Ordering combines three things we read from primary sources: Google review count and rating, years trading taken from the company’s Better Business Bureau profile rather than its own marketing, and its BBB letter grade. BBB accreditation is shown but never scored, because it is a paid membership rather than a mark of quality.

Check any contractor license yourself at the state register. Do that before you sign anything, with any company, including ours.

What this looks like on a Duke Indiana bill

An average Indiana household, against a system sized to cover its year. The energy charge is the part that goes to zero. The fixed monthly charge underneath it is the part that never does, and it is the number that decides whether a system pays for itself.

Meter reading falling from 41926 to 41675 kilowatt hours. A 901 kilowatt hour month against 1,152 kilowatt hours produced leaves 0 kilowatt hours billed and 251 banked for next month, so the energy charge falls from $157.77 to $0.00 at 17.51 cents per kilowatt hour.

Indiana average household use, 901 kWh a month, at the current published residential price of 17.51¢ per kWh. Your utility still bills a fixed monthly customer charge that no system offsets, so this is the energy part of the bill, which is the part that goes away.

Duke Indiana requirementRequired

Battery backup is mandatory
in Duke Indiana territory.

Duke Indiana does not credit the power you send back at the rate it charges you to take it.

That does not make solar a bad idea in Duke Indiana territory. It changes what you should build. When exports are worth a fraction of retail the credit stops being the return, and the job becomes using more of your own production inside the house, which usually means a larger array than a one for one utility would need.

Sizing is where that gets decided, so ask about it directly. Indiana pays roughly a quarter of the retail rate for exports, so the size that makes sense is the size the house can absorb during daylight. Every kilowatt hour beyond that is sold at wholesale plus a quarter. Duke Indiana sets its own limits. Ask Duke Indiana what it allows before you accept that a bigger system is off the table.

A battery then does two separate jobs. It moves daytime production into the evening so you use it instead of selling it, and it keeps the house running when the grid goes down. That second job is not a bonus. Panels on their own shut off in an outage, by design, so a roof full of them powers nothing during a storm. That is the part we will not refer around.

So we treat it as a requirement, not an upgrade. We will not refer you for a panels-only system in Duke Indiana territory, and you should be skeptical of anyone who quotes you one without raising storage first.

What your installer should be telling you

Ask for this utility’s current EDG rate in writing and ask what rate the savings model used for later years. It is reset annually against the wholesale market.

What Duke Indiana bills you anyway

In a month when your production covers everything you use, the energy charge can reach zero. This does not. It is the floor under every bill, and it is the number that decides whether a system pays for itself.

The charge
$10.54 a month, plus riders
How it is set
Duke calls it a Connection Charge here, not a customer charge, which is worth knowing if you go looking for it: Rate RS sets “Connection Charge $10.54” and then “Monthly Minimum Charge — The minimum charge shall be the Connection Charge.” Energy above it is tiered, 14.8799 cents for the first 300 kilowatt hours and 9.8147 cents beyond. The floor is higher than $10.54 and Duke does not publish the total. The rate carries a footnote — “Subject to the riders listed on Appendix A — List of Applicable Rate Adjustment Riders” — so what you actually pay is the Connection Charge plus whatever those riders come to, the same shape as AEP Ohio. Going solar does not move you to another rate: the Excess Distributed Generation rider bills you under your “standard rate schedule, inclusive of all applicable terms and rates”. What it does change is how exports are valued, and the method is unusual. Duke measures “the instantaneously determined total Excess Distributed Generation”, so only power leaving the house at that instant counts, and values it at a Marginal DG price of 4.1542 cents a kilowatt hour — the average wholesale price it paid in calendar 2023 multiplied by 1.25, as Indiana Code 8-1-40-17 requires. Instantaneous netting rewards using your own power as you make it far more than sending it back. One obligation that catches people: the rider requires you to carry homeowners or other insurance covering “at least one hundred thousand dollars ($100,000)” of liability arising from the generation equipment. Check your policy before you sign an interconnection agreement.

Applying to Duke Indiana

What Duke Indiana itself requires, as distinct from what the state rule requires. Read from its own published guidelines on the date shown.

Net metering closed on 1 July 2022
Senate Enrolled Act 309 ended it for new customers at all five investor owned utilities on the same date. Any quote offering Indiana net metering is describing a program you cannot join.
The replacement has a published formula
Excess Distributed Generation credit is the average wholesale price of electricity for the prior year, plus 25%. It is recalculated annually for each utility, so the rate moves with the wholesale market rather than with your bill.
What that works out to, and what you pay
Each utility posts its rate on its EDG rider. In 2026 AES Indiana pays 5.43 cents per kWh, NIPSCO 4.97, CenterPoint 5.56 and I&M 5.47, and Duke’s published sheet still shows 4.15 cents, set in 2024. Energy charges run from about 10 to 20 cents before riders, so an exported kilowatt hour earns between a quarter and a half of one you buy.
The rate is not locked
Because it is reset annually against the previous year’s wholesale average, the figure in your savings model is this year’s number and not a twenty year assumption. Ask what the model assumed for years two onward.
Cooperatives and municipal systems are outside the statute
SEA 309 bound the five investor owned utilities. If your provider is a co-op or a municipal system, ask for its own terms; some are better than the statutory replacement.

Duke Indiana net metering questions

Does Duke Indiana offer one for one net metering?
No. Exports are bought under Excess Distributed Generation at the prior year’s average wholesale price times 1.25, between about 4.2 and 5.6 cents per kWh across the five utilities in 2026, against energy charges of roughly 10 to 20 cents.
What does Duke Indiana pay for power sent back to the grid?
Wholesale plus 25%, about a quarter of retail. Per each utility’s own EDG tariff.
Do I need a battery with Duke Indiana?
Yes, and we treat it as mandatory. Because Duke Indiana does not credit exports one for one, the return has to come from using your own production rather than selling it, which after dark means storage and usually a larger array than a one for one utility would need. The other half is backup: panels alone shut off in an outage, so a battery is what keeps the house running in a storm. We do not refer panels-only systems in Duke Indiana territory. This is our referral policy, not a legal or utility requirement.
How do I find my Duke Indiana bill?

What is the catch with Duke Indiana?
