Net metering
Oklahoma statute 17 O.S. Section 156 requires regulated investor-owned utilities to offer net metering for systems up to 300 kW. However, excess generation beyond monthly usage earns a credit at avoided cost rather than full retail, typically 2 to 8 cents per kWh compared to the retail rate of 12.89 cents per kWh. Credits carry forward indefinitely to future bills. Oklahoma Gas and Electric (OG&E) and Public Service Company of Oklahoma (PSO) are the primary utilities that must participate. Many rural electric cooperatives and municipal utilities are exempt from this requirement and may offer different or no export programs.
OG&E (Oklahoma Gas and Electric) and PSO (Public Service Company of Oklahoma) must offer net metering under 17 O.S. Section 156. Export credit rates are set at avoided cost and are substantially below retail. Rural co-ops are not required to participate and terms vary by co-op. Verify your specific utility's export rate before finalizing system size.

Savings example
This example uses real Oklahoma market data. No federal residential credit is applied. Figures are illustrative; your in-home assessment uses your actual utility bills and the current rate schedule for your specific utility.
System size 14.5 kW at $2.56 per watt (EnergySage April 2026). Annual production estimated at 21,000 to 25,000 kWh based on Oklahoma City area peak sun hours of 5.5 to 6.0. Assumes 75% self-consumption at 12.89 cents per kWh retail value plus 25% exported at avoided-cost rate (well below retail). Federal residential credit: $0 (expired). Figures are illustrative; your in-home assessment will use your actual utility bills and current OG&E or PSO rate schedule.
Oklahoma OG&E customer (illustrative)
Illustrative example. Federal residential credit: $0 (Section 25D expired December 31, 2025). Your estimate will use your actual utility bills and current rate schedule.
Permitting
Oklahoma does not have a statewide solar permit fee cap. Permit requirements, fees, and timelines vary by local Authority Having Jurisdiction (AHJ). Major metro areas (Oklahoma City, Tulsa) typically have permit timelines of 2 to 4 weeks. SolarAPP+ adoption is not widespread in Oklahoma. Utility interconnection is handled directly with OG&E or PSO. Contract to energization typically runs 8 to 12 weeks depending on jurisdiction and utility queue.
Co-op and municipal utility interconnection processes vary significantly. Confirm interconnection requirements with your specific utility before signing a contract. AHJ permit timelines for rural areas may differ from metro estimates.
Commercial solar in Oklahoma
The commercial solar credit (Section 48E, 30 percent) remains available for qualifying commercial projects. Construction must begin by July 4, 2026 to qualify for the full placed-in-service window. Combined with MACRS accelerated depreciation and 100 percent first-year bonus depreciation, the combined first-year federal benefit can reach 45 to 55 percent of project cost for many Oklahoma business owners. Direct Pay is also available for nonprofits, municipalities, and other tax-exempt entities.
