Battery backup is mandatory
in PSO territory.
PSO 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 PSO 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. Oklahoma allows systems up to 300 kW but pays avoided cost for anything you export, against some of the cheapest retail electricity in the country. Both point at a system sized to the load in the house rather than to the roof. PSO sets its own limits. Ask PSO 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 PSO territory, and you should be skeptical of anyone who quotes you one without raising storage first.

Applying to PSO
What PSO itself requires, as distinct from what the state rule requires. Read from its own published guidelines on the date shown.
- The size limit is generous and the price is not
- The Corporation Commission requires net metering for systems up to 300 kW. Surplus is compensated at the utility’s avoided cost rate, reported roughly in the two to eight cent range.
- OG&E is reported at around four cents
- Confirm the current figure in writing. Reported values move, and a savings model built on a good year is not a forecast.
- Cheap retail power cuts both ways
- Oklahoma has some of the lowest residential electricity prices in the country, so the bill a system is offsetting is smaller to begin with. Payback here is genuinely longer than the national headline.
- The arrangement has been challenged before
- OG&E has petitioned the Commission in previous rate cases to reduce net metering compensation, arguing cost shift. As of early 2026 the current arrangement stands. Ask what happens to existing customers if it changes.

PSO net metering questions
- Does PSO offer one for one net metering?
- No. Net metering is required for systems up to 300 kW, with surplus energy compensated at the utility’s avoided cost rate rather than the retail rate.
- What does PSO pay for power sent back to the grid?
- Avoided cost, roughly four cents. Per the utility’s tariff.
- Do I need a battery with PSO?
- Yes, and we treat it as mandatory. Because PSO 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 PSO territory. This is our referral policy, not a legal or utility requirement.
- How do I find my PSO bill?
- Sign in at psoklahoma.com. Open My Account, then Billing. Open the latest bill and save the PDF. Or screenshot the summary page. If you cannot get to it, a rough guess at your average monthly amount is enough to start.
- What is the catch with PSO?
- Get the current avoided cost figure in writing, and ask what protection existing customers have if the Commission revisits the rate.
Installers serving PSO customers
Pick one. Only the company you choose receives your details, and only that company calls you.
These are real companies operating in PSO territory, 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.
