What Public Service Company does

Public Service Company of Oklahoma (PSO) is a regulated electric utility that has delivered electricity to customers in northeastern Oklahoma since 1913. The company is headquartered in Tulsa and operates as a wholly-owned subsidiary of American Electric Power (AEP), one of the largest investor-owned utility holding companies in the United States. PSO serves residential, commercial, and industrial customers across its franchise service territory under the regulatory oversight of the Oklahoma Corporation Commission, with rate base and capital recovery determined by formal rate cases.

PSO's core product is electricity distribution, delivered through traditional utility infrastructure augmented by self-healing grid automation technology that monitors current flow and automatically re-routes power during outages to reduce service interruptions. Beyond core delivery, the company offers a portfolio of optional programs including Residential and Business Electricity Service, Renewable Energy Choice (renewable energy certificates), Time-of-Day dynamic pricing, an EV Rate for electric vehicle owners, Power Pay Prepaid Electricity, Solar Programs, and HomeServe partnership home-repair plans. Grid reliability infrastructure investments — including tree trimming, automation equipment, and system upgrade projects across Tulsa, Okmulgee, and Pine & Peoria — are positioned as part of a sustained modernization effort.

PSO's revenue model is built on regulated utility rates, with recovery of operating costs, capital investments, and approved returns determined through rate proceedings before the Oklahoma Corporation Commission. The company has filed a rate case requesting a 15% rate increase (approximately $25/month for average residential customers) to fund grid upgrades, tree trimming, and new generation capacity. PSO is also pursuing large-load industrial customers — including a pending power supply agreement for a $5 billion aluminum smelter in Inola, Oklahoma — and dedicated rate options for data centers, positioning itself to capture demand from energy-intensive digital and manufacturing infrastructure within its existing service territory.

Expansion highlights5 records

Broad incumbents

• Evergy: Evergy (NYSE: EVRG) is a Midwest regulated electric utility serving Kansas and Missouri with a comparable customer mix, regulatory framework, and focus on grid modernization — useful as a benchmark for utility valuations in similar jurisdictions.
• American Electric Power (AEP): AEP is PSO's publicly traded parent company (NYSE: AEP) and one of the largest U.S. utility holding companies. As PSO's corporate parent and capital allocator, AEP's investment thesis, regulated ROE framework, and capital structure directly determine PSO's financial trajectory.
• Southern Company: Southern Company (NYSE: SO) is a major regulated electric utility holding company operating across the Southeast. Comparable business model with multi-state rate-regulated subsidiaries, large industrial customers, and significant grid-investment programs.
• NextEra Energy: NextEra Energy (NYSE: NEE) is the largest U.S. electric utility by market cap, operating regulated Florida Power & Light and a massive renewables arm. It serves as a benchmark for regulated utility valuation, capital allocation, and renewable-energy strategy relevant to PSO's growth trajectory.
• WEC Energy Group: WEC Energy Group (NYSE: WEC) operates regulated electric, gas, and renewable utilities across the Midwest. Comparable regulated rate-base model, multi-utility corporate structure under a holding company, and similar scale of capital investment programs.
• Duke Energy: Duke Energy (NYSE: DUK) is one of the largest U.S. regulated electric utilities, serving customers across the Southeast and Midwest. Comparable in scale, regulated rate-base model, grid-modernization capex profile, and exposure to industrial/data-center load growth.

Direct peers

• Liberty Utilities (formerly Empire District Electric): Liberty Utilities' Empire District subsidiary serves electric customers across southwestern Missouri, Oklahoma, Arkansas, and Kansas — directly overlapping with PSO's Oklahoma franchise territory and competing for similar small-to-mid commercial load.
• Oklahoma Gas and Electric Company (OGE Energy): OGE Energy's regulated subsidiary OG&E is the other major investor-owned electric utility serving Oklahoma. It directly competes with PSO for industrial customers and rate-base investment opportunities within the same Oklahoma Corporation Commission jurisdiction.
• Public Service Company of New Mexico (PNM Resources): PNM is PSO's corporate 'sister company' under the AEP umbrella — both operate as regulated electric utility subsidiaries with similar scale, customer mix, and rate-base profiles. Blackstone Infrastructure's pending $175M community commitment acquisition of TXNM/PNM also establishes a direct precedent for valuing AEP utility subsidiaries.

Regional players

• Southwestern Public Service (Xcel Energy): Xcel Energy's SPS subsidiary serves the Oklahoma panhandle, Texas, and New Mexico — overlapping geography and similar rural/industrial customer profile to PSO. Comparable in scale and service territory characteristics, though operating under a different state regulator.
