Oklahoma businesses may qualify for commercial energy rebates when they install eligible lighting, HVAC, refrigeration, food-service, building-envelope, control, compressed-air, and other energy-efficient equipment. Public Service Company of Oklahoma (PSO) offers prescriptive, midstream, custom, and small-business programs designed to reduce project costs and electricity consumption.

Most incentives discussed in this guide are available to qualifying commercial and industrial customers with at least one meter on an eligible PSO electric rate schedule. However, equipment requirements, application deadlines, preapproval rules, and funding availability can affect whether a project qualifies.

Key Takeaways

PSO’s 2026 programs cover both common equipment replacements and complex, site-specific energy projects.

What should Oklahoma businesses know about commercial rebates in 2026?

• PSO offers commercial rebates for LED lighting, lighting controls, HVAC controls, VFDs, refrigeration, kitchen equipment, building-envelope improvements, plug-load controls, and other technologies.
• Qualifying HVAC equipment may receive an instant discount when purchased through participating distributors or service providers.
• Custom rebates may support air compressors, chillers, energy management systems, geothermal systems, process equipment, motors, pumps, and projects not covered by prescriptive incentives.
• Projects involving multiple qualifying upgrade categories may be eligible for a bonus rebate of up to 20% of the combined rebate amount.
• Some projects require formal PSO preapproval before equipment is purchased or installed.

What Commercial Rebates Are Available in Oklahoma in 2026?

PSO divides its commercial energy-efficiency offerings into several program pathways. Prescriptive rebates provide predetermined amounts for qualifying equipment, while the Midstream Program applies instant discounts through participating distributors and service providers. Custom rebates address projects that require site-specific energy-savings calculations.

The following table summarizes major 2026 opportunities.

These are examples, not a complete eligibility determination. PSO states that rebates are available while funds last and may change during the program period.

What Commercial Lighting Rebates Are Available in Oklahoma?

Oklahoma businesses served by PSO can qualify for LED lighting rebates in 2026. Incentives cover retrofit projects, new construction, interior and exterior lighting, and certain lighting controls.

What LED Lighting Retrofits May Qualify?

What Commercial Lighting Rebates Are Available Through PSO?

PSO offers 2026 commercial lighting incentives through three pathways: prescriptive rebates for lighting retrofits, performance-based rebates for new construction, and instant discounts on qualifying LED tube lamps. The applicable pathway depends on whether the project replaces existing lighting, installs lighting in new construction, or purchases eligible equipment through a participating distributor.

Which Lighting Retrofits May Qualify for PSO Rebates?

Commercial lighting retrofits can qualify for fixed incentives per lamp, fixture, sign, or control. PSO also offers performance-based incentives for qualifying projects that use the wattage-reduction method.

The exact incentive depends on the existing lighting, proposed LED equipment, wattage reduction, application, and applicable PSO technical requirements. Businesses should verify that the proposed equipment qualifies before purchasing or installing it.

What Is the Wattage-Reduction Method?

The wattage-reduction method provides a rebate of $0.10 per annual kilowatt-hour reduced for qualifying lighting retrofits that do not fit a standard one-for-one prescriptive measure.

This pathway may apply to:

• LED-to-LED fixture replacements
• TLED-to-LED fixture replacements
• TLED-to-TLED replacements
• Projects that change fixture quantities or layouts
• Other lighting retrofits that cannot be calculated with a standard per-fixture rebate

PSO calculates the incentive using the project’s documented reduction in lighting energy use. The project must satisfy applicable technical and application requirements.

What New Construction Lighting Rebates Are Available?

PSO offers separate incentives for qualifying interior and exterior lighting installed in new construction.

Interior new construction incentives are based on how far the proposed lighting system reduces connected wattage below the applicable ASHRAE/IESNA baseline. Projects achieving a greater reduction may qualify for the higher incentive tier.

Exterior rebate amounts depend on the wattage of the proposed LED fixture and the type of lighting being replaced or installed.

Are Instant Discounts Available for LED Tube Lamps?

Yes. Qualifying LED tube lamps, commonly called TLEDs, may receive an instant discount of $3 per lamp through participating PSO distributors.

Because the discount is applied through the distributor, the customer may receive a reduced purchase price instead of submitting a traditional post-purchase rebate application. Businesses should confirm that the product and distributor participate in PSO’s Midstream Program before placing the order.

When Do Lighting Projects Require Preapproval?

PSO requires preapproval before equipment is purchased or installed for:

• New construction lighting projects with 250 or more fixtures
• Retrofit projects with 100 or more high-bay or exterior fixtures
• Retrofit projects with 500 or more total fixtures
• Lighting projects submitted through a custom rebate pathway

Purchasing or installing lighting equipment before receiving required preapproval can disqualify the project from receiving an incentive.

What Commercial HVAC Rebates Are Available in Oklahoma?

PSO offers instant midstream incentives for qualifying new construction and retrofit HVAC systems purchased through participating distributors and service providers. Eligible categories include:

• Split and unitary air conditioners
• Split and unitary air-source heat pumps
• Packaged terminal air conditioners and heat pumps
• Variable refrigerant flow air conditioners and heat pumps
• Water-source heat pumps
• Dual-enthalpy economizer controls installed on new HVAC units

Because midstream discounts are applied through participating market partners, the incentive may appear as a reduced purchase price rather than a separate rebate payment.

What HVAC Controls and VFDs Qualify?

Retrofit installation of networked HVAC controls may qualify for $250 per thermostat or zone sensor.

Hotels may receive $60 per room for qualifying occupancy-based PTAC or PTHP controls with a five-degree setback or $80 per room with a 10-degree setback.

Variable-frequency drives installed on existing HVAC equipment may qualify for $300 to $9,000 per unit, based on motor horsepower. Eligible applications include supply and return fans, exhaust fans, make-up air fans, cooling-tower fans, hot-water pumps, chilled- or condenser-water pumps, and water-source heat-pump circulation loops. Projects exceeding 100 horsepower require a custom application.

What Refrigeration Rebates Are Available for Oklahoma Businesses?

PSO’s commercial refrigeration rebates can support grocery stores, restaurants, convenience stores, hospitality properties, schools, and other facilities with significant refrigerated storage.

Available measures include:

• ENERGY STAR reach-in refrigerators: $40 to $100 per unit
• ENERGY STAR reach-in freezers: $80 to $200 per unit
• ENERGY STAR ice machines: $100 to $200 per unit
• Anti-sweat heat controls: $100 per door
• Door gaskets: $4 per linear foot
• Electronically commutated evaporator fan motors: $100 per motor
• Refrigeration suction-pipe insulation: $1 per foot
• Strip curtains: $10 per square foot
• Walk-in door closers: $75 per door
• Zero-energy doors: $200 to $300 per door
• Variable-speed refrigeration compressor controls: $300 per ton

Eligibility depends on the existing condition, proposed equipment, temperature range, equipment capacity, and PSO technical requirements.

Are There Commercial Kitchen Equipment Rebates in Oklahoma?

PSO offers incentives for several types of ENERGY STAR commercial kitchen equipment. Rebates include:

Kitchen demand-ventilation controls adjust exhaust-fan operation based on cooking activity. This can reduce fan energy use and conditioned-air losses during slower operating periods.

Which Building-Envelope Improvements May Qualify?

PSO offers prescriptive incentives for several retrofit measures that reduce heating and cooling loads:

• Ceiling insulation: $0.15 per square foot
• Roof-deck insulation: $0.15 per square foot
• Cool roofs: $0.08 per square foot
• Duct insulation: $0.20 per square foot
• Window film: $2 per square foot
• Door weatherstripping: $0.50 to $30 per foot

Each measure has technical conditions. For example, qualifying ceiling insulation must raise an existing R-value of R-22 or less to at least R-30. Cool-roof projects must cover at least 75% of the roof and satisfy PSO’s reflectivity and thermal-emittance requirements.

What Other Commercial Equipment Rebates Are Available?

PSO also provides incentives for equipment that reduces plug loads or improves operational efficiency. Examples include computer power-management software, high-frequency forklift battery chargers, smart power strips, vending-machine controls, commercial clothes washers, variable-speed pool pumps, and ENERGY STAR vending machines.

Incentives generally include:

• Computer power-management software: $10 per laptop or $15 per desktop
• High-frequency forklift battery chargers: $500 per charger
• Smart power strips: $10 per strip
• Occupancy-controlled smart power strips: $20 to $50 per strip
• Vending-machine controls: $50 to $100 per unit
• Commercial clothes washers: $50 to $150 per unit
• Variable-speed commercial pool pumps: $300 to $1,000 per unit

How Do PSO Custom Rebates Work?

Custom rebates cover energy-efficiency projects that do not fit PSO’s prescriptive categories. These measures must demonstrate verifiable electricity savings and document the associated project costs before PSO can determine eligibility and the potential incentive.

Custom opportunities may include:

• Air compressors and compressed-air system improvements
• Chillers and central plant improvements
• Data-center cooling
• Energy management systems
• Geothermal systems
• HVAC system improvements
• Motors, pumps, and process VFDs
• Manufacturing and process equipment
• Agricultural improvements
• Oil and gas equipment
• Specialty lighting, including pool, stage, theater, and grow lighting
• Comprehensive facility upgrades

All custom projects require preapproval. Businesses should complete the analysis and application process before purchasing or installing equipment.

Can Businesses Earn More by Combining Multiple Upgrades?

Commercial customers that complete at least three different qualifying upgrade types, such as lighting, HVAC, kitchen equipment, or custom projects, may qualify for an additional bonus rebate of up to 20% of the combined rebate amount.

This creates an opportunity to evaluate a facility as a complete system instead of submitting unrelated equipment replacements. However, PSO must confirm which measures count as separate upgrade types and whether the proposed package meets current bonus requirements.

When Is PSO Preapproval Required?

PSO requires project preapproval and supporting documents before equipment is purchased or installed for:

1.      All custom projects
2.      Networked HVAC control projects with 17 or more thermostats and zone sensors
3.      New construction lighting projects with 250 or more fixtures
4.      Retrofit lighting projects with at least 100 high-bay or exterior fixtures
5.      Retrofit lighting projects with at least 500 total fixtures

Purchasing or installing equipment before required preapproval can jeopardize rebate eligibility. Projects that do not require preapproval must generally be submitted with all required documentation within 60 days of the invoice date.
