Duke Energy Florida net metering in Florida

North central Florida and the Gulf coast.

Type
Investor owned
Accounts
2.0M

What they credit you

Full retail rate

Set by state rule

One kilowatt hour out is worth one kilowatt hour in.

Month to month
Credits roll forward month to month, for no more than twelve months.
Once a year
At the end of each calendar year the utility pays out any unused credits at an average annual rate based on its COG-1 as-available energy tariff, which is well below the retail rate.
System size
The state rule caps generation at 90% of your distribution service rating. Your utility may also cap the system against your own past usage; where it does, that is its own policy rather than the rule, and it is shown on this page.

Installers serving Duke Energy 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 Energy territory. EPC Solar and Bold Energy are listed first because they are the companies we introduce first. Volt Home is listed last. 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 Energy bill

An average Florida 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 41618 kilowatt hours. A 1,104 kilowatt hour month against 1,412 kilowatt hours produced leaves 0 kilowatt hours billed and 308 banked for next month, so the energy charge falls from $166.70 to $0.00 at 15.10 cents per kilowatt hour. A fixed monthly charge of $30.00 still applies and is not offset.

Florida average household use, 1,104 kWh a month, at this provider’s own published residential rate. The fixed charge is its minimum bill: it lands at zero kilowatt hours, so nothing you generate removes it. Duke Energy Florida, Understanding the Minimum Bill, September 2026.

Duke Energy is investor owned, so Florida PSC Rule 25-6.065 applies and these terms are set by the state rather than by a board that can revise them. That is the strongest position a homeowner can be in on net metering.

What Duke Energy 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
$30.00 a month
How it is set
Duke applies a minimum usage fee that brings a low bill up to $30.00, so that is the floor under a net metered account whatever the energy line does. Read the relief provision carefully if someone offers it to you: Duke’s income-qualified modification is written for a customer "who is not also a net metering customer", so going solar puts the account outside it.

Applying to Duke Energy

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

The portal changed this year
Since 9 February 2026, Duke Energy Florida net metering interconnection requests go through PowerClerk. Anything an installer tells you about the old portal is out of date.
If your system is 10 kW or under
Tier 1. No application fee, no disconnect switch and no insurance requirement. You file the Tier 1 Interconnection Request Application and Compliance Form plus the Tier 1 Standard Interconnection Agreement.
Insurance at Tier 1
Duke recommends but does not require general liability cover of not less than $100,000. Recommended is not required, and you should not be told otherwise.
If your system is over 10 kW
Tier 2. A $240 application fee, proof of $1 million general liability insurance, and an externally accessible, lockable manual AC load break disconnect switch, which Duke specifies must not be a breaker, close to the meter.
The check that can cost you money
Duke verifies your system does not exceed 90% of the rating of your transformer or service drop. If it does, that equipment has to be upgraded and YOU pay for the upgrade before Duke will carry it out. Ask your installer to confirm your service rating before you sign, not after.
How long it takes
Duke replaces the meter within about three weeks of a completed Tier 1 application. Tier 2 runs three to four weeks from complete paperwork, plus an on-site inspection.
Do not switch it on early
Operating in parallel with Duke’s system without prior written permission to operate is prohibited. Permission is usually granted within 10 business days once everything else is done.
Your inverter has to be certified
UL 1741 and IEEE 1547, certified by a nationally recognized testing laboratory, with the manufacturer’s specification sheets attached to the application. Anything else needs extra protection equipment.
The bill floor, and a catch
A $30 per month minimum applies. Duke is offering income-qualified customers a minimum bill modification through 2027, but its own terms exclude net metering customers from the automatic version of that relief.

Duke Energy net metering questions

Does Duke Energy offer one for one net metering?
Yes. One kilowatt hour out is worth one kilowatt hour in. Credits roll forward month to month, for no more than twelve months.
What does Duke Energy pay for power sent back to the grid?
Full retail rate. At the end of each calendar year the utility pays out any unused credits at an average annual rate based on its COG-1 as-available energy tariff, which is well below the retail rate.
Do I need a battery with Duke Energy?
Not for the economics. Duke Energy credits exports at the retail rate, so power you send out during the day comes back at the same value after dark without storage. A battery is still worth considering for outages during hurricane season, but it is an upgrade here rather than a requirement.
How do I find my Duke Energy bill?
Sign in at duke-energy.com or open the Duke Energy app. Open Billing and Payments, then View bill history. Select the latest statement and download the PDF. A screenshot of the summary showing amount due and kWh works just as well. If you cannot get to it, a rough guess at your average monthly amount is enough to start.
