1. Overview​

Oklahoma operates a vertically integrated, regulated electricity market where customers cannot choose their providers. The Oklahoma Corporation Commission (OCC) regulates prices and reliability for investor-owned utilities (IOUs), and the state's grid management is integrated into the Southwest Power Pool (SPP) 1. The market is dominated by three primary IOUs: Oklahoma Gas & Electric (OG&E), Public Service Company of Oklahoma (PSO), and Liberty Utilities 2.

The state is a major net exporter, producing nearly three times more energy than it consumes 3. The generation mix has shifted significantly away from coal toward natural gas and wind. As of 2024–2025 estimates, natural gas accounts for approximately 45–50% of net generation, while wind energy comprises roughly 41–45% 4. Coal has declined to a minor contributor (6–7%), down from over 40% a decade ago. Solar currently represents less than 1% of the mix but is slated for significant growth through 2026 5.

Oklahoma ranks third in the nation for wind power production, with 12,748 MW of installed wind capacity as of April 2025 3. This rapid expansion has reduced the state's grid carbon intensity to approximately 673 lbs CO₂ per MWh (305–312 gCO₂eq/kWh) as of 2024–2025, making it roughly 25% cleaner than the U.S. national average 6.

Despite these transitions, retail rates remain low. As of early 2026, the average residential rate is approximately 12–14 cents/kWh, compared to the national average of ~17–19 cents/kWh 7. However, rates face upward pressure due to rising natural gas prices, grid upgrades, and unprecedented load growth driven by data centers and AI infrastructure 7.

2. Market Structure​

Oklahoma operates under a vertically integrated, regulated market structure. Retail electricity choice for residential and small business customers is not available; consumers must purchase power from their local utility monopoly 8. Rates are established and overseen by the Oklahoma Corporation Commission (OCC) 7.

Utility Ownership Models​

The state's electric utility landscape is composed of three primary ownership types:

  • Investor-Owned Utilities (IOUs): For-profit corporations regulated by the OCC.
  • Municipal Utilities: Community-owned, non-profit systems operated by local city governments. The Oklahoma Municipal Power Authority (OMPA) serves 43 municipal systems across 29 counties 9.
  • Electric Cooperatives: Not-for-profit, member-owned organizations serving rural and suburban areas. Most co-ops have opted out of state price regulation and set their own rates 9.

Wholesale Markets & ISO​

While retail competition is absent, Oklahoma participates in regional wholesale markets managed by the Southwest Power Pool (SPP). The SPP serves as the Independent System Operator (ISO) and Regional Transmission Organization (RTO) for the state, coordinating transmission across 14 states to ensure reliability and competitive wholesale pricing 7 10.

Legislative History​

Oklahoma initially passed the 1997 Restructuring Act with the goal of deregulating the market by 2002. However, the state suspended its transition following the 2000–2001 California energy crisis and concerns over transmission capacity, never fully implementing retail choice 7.

Current Rates​

As of March 2026, the residential electricity rate in Oklahoma is approximately 14.48 ¢/kWh 7.

3. Clean Energy Policy​

Oklahoma does not have a mandatory Renewable Portfolio Standard (RPS) or a legally binding state-wide net-zero goal for electricity. Instead, the state utilizes an "all-of-the-above" energy strategy focused on market-driven development [1].

Renewable Energy Goals In 2010, the Oklahoma Energy Security Act (HB 3028) established a voluntary goal for 15% of the state's total installed generation capacity to come from renewable sources by 2015. This goal has since expired, and the state did not set new interim targets or extensions [1][3]. Despite the lack of mandates, Oklahoma is a national leader in wind generation. As of 2024, wind energy accounts for approximately 41% to 47% of the state's total net electricity generation, far exceeding the original voluntary target [2][3].

Recent Legislative Changes (2025–2026) Legislative focus has shifted toward increased oversight and regulation of renewable facilities:

  • Renewable Energy Facility Act (HB 2155): Passed in March 2025, this act established a comprehensive regulatory framework for wind, solar, battery storage, and hydrogen projects [2].
  • Setbacks and Property Rights: Legislation such as HB 2751 has introduced stricter setback requirements, increasing the mandatory distance between wind turbines and residential homes or military installations [2].
  • Advanced Nuclear: In 2026, new legislation aimed to establish a state office to promote and regulate advanced nuclear reactors as part of the state's long-term energy strategy [2].

Incentives and Consumer Policies

  • Tax Credits: A 2025 legislative package (referred to as the "One Big Beautiful Bill") significantly phased out state-level tax credits for wind and solar projects, following the repeal of the primary wind tax credit in 2017 [2][4].
  • Net Metering: Customers with rooftop solar or small wind systems (up to 300 kW) can connect to the grid, but utilities are only required to purchase excess power at an avoided cost rate, typically lower than retail. Utilities may also charge additional fees to these customers [2].
  • Electric Vehicles (EVs): While alternative fueling infrastructure tax credits (up to 45%) remain available, new laws have introduced registration fees for EVs and hybrids to recoup lost fuel tax revenue [2].

Utility-Specific Targets While the state lacks mandatory targets, individual utilities have set corporate goals:

  • AEP Public Service Co. of Oklahoma (PSO): The parent company has a corporate-wide goal of reaching net-zero carbon emissions by 2050 [4].
  • Oklahoma Gas & Electric (OG&E): The utility has focused on maintaining coal operations through the end of the decade while offering voluntary renewable programs for customers [4].

4. Utility Landscape​

Oklahoma's electric market is served by a mix of investor-owned utilities (IOUs), electric cooperatives, and municipal authorities. The market is dominated by two primary IOUs regulated by the Oklahoma Corporation Commission:

  • Oklahoma Gas and Electric (OG&E): The state's oldest and largest electric utility, serving over 858,000 customers across a 30,000-square-mile territory in Oklahoma and western Arkansas. It is a subsidiary of OGE Energy Corp 1011.
  • Public Service Company of Oklahoma (PSO): The second-largest utility, operating as a subsidiary of American Electric Power (AEP), serving approximately 575,000 customers in eastern and southwestern Oklahoma 1011.

Liberty Utilities (formerly Empire District Electric) serves a portion of northeastern Oklahoma 12. Additionally, ITC Great Plains operates as an investor-owned transmission-only utility within the state 10.

The non-profit sector includes a vast network of cooperatives and public entities:

  • Electric Cooperatives: There are approximately 27 to 30 distribution cooperatives in the state, such as the Oklahoma Electric Cooperative (OEC). OEC, the largest co-op, serves about 63,000 meters across central Oklahoma 1013.
  • Oklahoma Municipal Power Authority (OMPA): A wholesale power supplier owned by 42 to 43 member municipal electric systems, serving over 118,000 customers across 29 counties 1013.
  • Grand River Dam Authority (GRDA): A state-owned utility providing wholesale electricity to municipal systems and industrial customers, primarily in the Grand River valley region 10.

5. SSS-Eligible Resources​

No specific SSS-eligible resources identified. See section notes.

6. EAC/REC Registry Infrastructure​

Oklahoma does not operate a state-specific Renewable Energy Certificate (REC) registry 14. Instead, renewable energy projects in the state typically utilize regional systems to track and retire Energy Attribute Certificates (EACs).

The primary tracking systems for Oklahoma include:

  • North American Renewables Registry (NAR): Frequently used by generators in states without a dedicated system, NAR serves as a central platform for creating, tracking, and retiring RECs in Oklahoma 151416.
  • Midwest Renewable Energy Tracking System (M-RETS): Operated by CleanCounts, M-RETS also tracks environmental attributes for projects located in Oklahoma 1716.

While the Oklahoma Corporation Commission (OCC) oversees public utilities and renewable energy policies, it does not manage a dedicated REC marketplace 14. To prevent double-counting, many Oklahoma renewable energy products are verified by third-party certification programs such as Green-e Energy 14.
