Utility landscape

• Public Service Company of Oklahoma (PSO) IOU

  Eastern Oklahoma, including Tulsa metro and surrounding areas

  AEP subsidiary subject to OCC oversight; filed a general rate case in 2023 addressing grid hardening and wildfire mitigation cost recovery. Faces ongoing scrutiny over fuel cost pass-through mechanisms following Winter Storm Uri debt securitization.

• Oklahoma Gas and Electric (OG&E) IOU

  Central and western Oklahoma, including Oklahoma City metro; also serves portions of Arkansas

  OGE Energy subsidiary that completed a significant rate case in 2023-2024 involving cost recovery for renewable integration and coal plant retirement transition costs. Active in OCC proceedings related to grid modernization and advanced metering infrastructure deployment.

• Oklahoma Natural Gas (ONG) IOU

  Statewide natural gas distribution across Oklahoma

  ONE Gas subsidiary; secured OCC approval for securitization of Winter Storm Uri extraordinary gas procurement costs totaling approximately $2.1 billion. Continues to litigate customer allocation methodologies and pipeline integrity rider recovery.

• Western Farmers Electric Cooperative (WFEC) coop

  Wholesale power supplier to distribution cooperatives across western and southwestern Oklahoma

  G&T cooperative not directly rate-regulated by OCC but subject to oversight in interconnection and transmission matters. Navigating transition away from coal generation at Anadarko and Hugo plants with implications for member cooperative rates.

• Indian Electric Cooperative (IEC) coop

  Creek, Okfuskee, Okmulgee, and surrounding counties in east-central Oklahoma

  Distribution cooperative with rates set by board but subject to OCC certificate of convenience and necessity requirements for service territory expansions. Active in broadband deployment through USDA ReConnect and RDOF funding programs.

• Oklahoma City Utilities (Water/Wastewater) muni

  Oklahoma City and surrounding municipalities under wholesale water agreements

  Municipal utility largely outside OCC electric/gas jurisdiction but intersects with OCC in right-of-way and certificate proceedings. Ongoing rate sufficiency review to fund Lake Draper expansion and lead service line replacement under federal LCRR mandates.

Key issues

• Winter Storm Uri securitization implementation and customer surcharge disputes: ONG and OG&E continue to face OCC proceedings over the amortization schedules, interest rate assumptions, and equitable allocation of securitized fuel costs across customer classes, with industrial intervenors challenging residential cross-subsidization arguments.
• Coal plant retirement and stranded cost recovery: WFEC and PSO are both managing accelerated coal retirements driven by federal environmental rules and economics; OCC is evaluating whether undepreciated plant balances and transition costs should be recoverable through rate riders or deferred in general rate cases.
• Grid modernization and AMI deployment cost recovery: OG&E's pending AMI rollout and associated data privacy, cybersecurity, and rate design implications are before the OCC, with consumer advocates contesting the proposed cost-benefit methodologies and time-of-use rate structures tied to smart meter deployment.
• Renewable energy integration and transmission cost allocation: Rapid wind and solar development in western Oklahoma is creating congestion and interconnection queue backlogs on the SPP system; OCC is engaged in stakeholder proceedings on state-level transmission planning coordination and cost allocation principles for new high-voltage lines.
• Broadband certification and right-of-way access for electric cooperatives: OCC is processing an increased volume of certificate and pole attachment proceedings as electric cooperatives deploy fiber broadband under federal funding programs, creating jurisdictional tension between OCC authority and municipal franchise agreements.
