PSO Adds 795-Megawatt Plant to Strengthen Oklahoma Grid

Posted

The Public Service Company of Oklahoma (PSO), a subsidiary of AEP, has completed its acquisition of the Green Country Power Plant, a 795-megawatt (MW) natural gas facility located in Jenks. With final approval from the Oklahoma Corporation Commission, PSO assumed full operational control of the plant on June 30, integrating it into the utility’s statewide generation portfolio.

The acquisition is part of PSO’s broader strategy to strengthen grid reliability, enhance local power generation, and support long-term demand growth across Oklahoma.

Leigh Anne Strahler, PSO president and COO, stated: 

“Today represents a major step forward in our mission to serve our customers. The Green Country Power Plant will play an important role in delivering reliable power to support Oklahoma homes and businesses while ensuring grid stability and supporting the state’s economic growth.”

Natural Gas as a Pillar of Grid Stability in Oklahoma

As energy demand increases—driven by industrial expansion, electrification, and extreme weather—utilities are reevaluating their generation portfolios to ensure resiliency. The Green Country facility adds firm, dispatchable capacity to PSO’s system, helping it meet peak load demands and offset intermittent renewable generation during low-output periods.

While natural gas remains a transitional fuel in the clean energy shift, its role in ensuring short- and medium-term grid reliability is still critical—particularly in states like Oklahoma, which face high seasonal variability and aging infrastructure.

Economic Benefits for Tulsa County and Local Schools

Beyond stabilizing the grid, the acquisition brings tangible local economic impacts. PSO noted that the plant will contribute increased tax revenue to Tulsa County, directly benefiting public schools and municipal services. It also supports job retention and creation, adding operational and maintenance roles to the area.

The facility is expected to serve as a long-term economic anchor in Jenks, reinforcing PSO’s stated commitment to investing in the communities it serves.

Balancing Reliability with Long-Term Sustainability Goals

Although this acquisition underscores PSO’s commitment to reliability, it also signals the utility’s broader challenge: balancing the immediate need for dispatchable energy with its longer-term decarbonization strategy.

As Oklahoma continues to diversify its grid—particularly with investments in wind, solar, and battery storage—the Green Country facility will likely act as a stabilizing force to support intermittent resources until larger-scale clean baseload solutions are viable.
