The state framework sets the default. Where PSO (AEP) pays something different, the utility tariff governs and is what the card above reports.
| Compensation mechanism | Net energy billing: generation offsets on-site consumption at the applicable retail rate during the billing period; net excess is paid or credited at the utility's avoided energy cost in the next billing period. |
|---|---|
| Export rate | There is no single statewide dollar export rate. Net excess is credited or paid at the utility's avoided energy cost, while generation up to on-site consumption is netted at the applicable retail energy rate. |
| Rate effective | The statewide rule text was amended effective July 25, 2019. Current utility tariffs read for this record show OG&E NEBO effective January 1, 2025 and PSO NEBO effective January 2, 2024; PSO's separate QF purchase schedule is effective April 30, 2026. |
| Credit rollover | Credits are handled by monthly billing: net excess is credited or paid in the next billing period. OG&E and PSO both state that credits can carry forward, subject to their one-time-payment provisions after more than 24 consecutive months or when the credit exceeds $100. |
| Credit expiration | No annual expiration is stated in the reviewed statewide rule. OG&E and PSO instead provide a one-time payment option when a credit carries forward longer than 24 consecutive months or exceeds $100, rather than describing an automatic annual forfeiture. |
| Annual true-up | No statewide annual true-up date is stated. The rule defines the billing period as the monthly bill period and requires net excess treatment in the next billing period; utility tariffs govern any account-closing payment. |
| Aggregate program cap | No statewide aggregate MW cap is stated in the reviewed OAC 165:40:9 text. The rule sets a per-facility 300 kW eligibility limit, while utility tariffs may limit installations on an individual distribution circuit or substation. |
| Program status | The statewide optional net-energy-billing rule is effective in all territories served; participation remains subject to the 300 kW/125%-of-peak-load eligibility rules and utility circuit or substation limits. |
| Grandfathering | PSO's NEBO tariff says customers who were on a Residential or Commercial Net Metering rate before NEBO's effective date are placed on the applicable NEBO TOD schedule and are not required to sign a new purchase agreement; no broader statewide grandfathering rule was identified. |
| Regulator | Oklahoma Corporation Commission, Public Utility Division. |
| Governing rule | 17 O.S. § 156; OAC 165:40:9 (Optional Net Energy Billing Purchase Rate). |
