Public Service Company of Oklahoma (PSO) solar: net metering and export credit rules

The rules

What happens to the solar power you send to the grid

PSO, an American Electric Power company based in Tulsa, serves more than 587,000 customers in 232 communities in eastern and southwestern Oklahoma.

Net Energy Billing Option (NEBO)

How Public Service Company of Oklahoma (PSO) credits exports

Public Service Company of Oklahoma credits home solar under its Net Energy Billing Option (NEBO), which requires the customer to take service on PSO's standard time of day rate, sign PSO's Standard Electricity Purchase Agreement, and have the system's total output measured by a separate production meter.
Energy is netted within each monthly billing period, and during the June through October on peak season it is netted separately within the on peak and off peak intervals, with only the kilowatt hour units of the bill affected.
When the system produces more than the home uses, the excess is credited, or paid, in dollars in the next billing period at PSO's on peak or off peak avoided energy cost, which PSO calculates each month from Southwest Power Pool day ahead market prices and posts on its rates page.
If a credit carries forward longer than 24 consecutive months or grows past a limit set in the tariff, PSO or the customer may choose a one time payment, and a customer who leaves PSO's system with a credit receives a one time payment when the account closes.
Customers who were on PSO's earlier net metering tariff before NEBO took effect were assigned the time of day rate for their rate class.

The rule behind it

Oklahoma Corporation Commission optional net energy billing rule and distributed generation statute, OAC 165:40-9; 17 O.S. § 156

The program

Net Energy Billing Option (NEBO), Schedule NEBO, Sheet No. 51 (2nd Revised)

Recent changes

PSO's current NEBO schedule took effect January 2, 2024 under Oklahoma Corporation Commission Order No. 738571, and since January 1, 2024 PSO has required connected equipment to meet the 2018 edition of IEEE Standard 1547 or its equivalent.

Before you connect

Limits, and the steps to get connected

Limits and eligibility

NEBO is available to systems with a maximum rated capacity of 300 kW or less.
No net energy facility may have installed capacity greater than 125 percent of the customer's annual peak demand, and a larger system may be moved to PSO's QF Standard Purchase Schedule, with peak demand first based on the 12 months before the customer requests NEBO.
The system must be on the customer's premises and intended primarily to offset the energy PSO would otherwise supply there, and usage from multiple service points cannot be combined.
PSO may limit the number of net energy installations on any distribution circuit or substation for operational reasons, and final selection and participation in NEBO are at PSO's sole discretion.

How a home gets connected

Before anything is installed, the homeowner or installer registers with PSO's online PowerClerk portal and submits an interconnection application, and PSO recommends getting an approved application before committing to a vendor or contractor.
After the application is complete and signed, PSO performs a technical review; UL 1741 certified inverter systems of 25 kW or less go through an automated review, and larger systems go through an expanded review.
PSO then provides an Interconnection Service Agreement, with an estimate for any needed upgrades, and construction can move forward after the customer signs it and pays for any required interconnection equipment; NEBO customers also sign PSO's Standard Electricity Purchase Agreement.
After installation, the equipment must be inspected and certified by the government authority having jurisdiction, or by a licensed electrician or licensed professional engineer if none has jurisdiction, and PSO checks meter function, placards, disconnects and safe access.
PSO issues a Permission to Operate letter after installation, any required upgrades or meter updates, testing and commissioning, and payment of any interconnection costs are complete, and a separate distributed generation meter, also called a production meter, measures how much energy the system generates.

Federal tax credit

The residential solar credit (section 25D) ended for systems completed after 2025. What that means in 2026.

Questions

Common questions about Public Service Company of Oklahoma (PSO) and solar

How does PSO credit extra solar power I send to the grid?

Under PSO's Net Energy Billing Option, your solar output offsets the energy you use during the monthly billing period. Any excess is credited, or paid, in dollars in the next billing period at PSO's on peak or off peak avoided energy cost, which PSO calculates monthly from Southwest Power Pool day ahead market prices.

Do I need a new meter or a different rate for solar with PSO?

Yes. NEBO customers must take service on PSO's standard time of day rate, and the system's total output must be measured by a separate production meter, as described in PSO's Customer Interconnection Guide. That production meter operates separately from the regular meter that measures how much energy the home uses from PSO.

When can I turn on my solar system in PSO's territory?

PSO issues a Permission to Operate letter only after the installation, any required upgrades or meter updates, and testing and commissioning are complete. Depending on the size of the system, PSO may require proof of local inspections and testing, and it checks meter function, placards, disconnects and safe access.

Is there still a federal tax credit for home solar?

The federal residential clean energy credit, section 25D, ended for home solar expenditures made after December 31, 2025, under the law signed July 4, 2025. The IRS treats the expenditure as made when installation is completed, so a system completed in 2026 does not qualify even if it was paid for earlier.

Does the consultation cost anything?

No. The consultation is free for homeowners, and there is no obligation to buy anything.
