OGE ENERGY CORP
OG&E submits this Integrated Resource Plan (IRP) - Draft in compliance with requirements established pursuant to the Oklahoma Corporation Commission's (OCC) Electric Utility Rules OAC 165:35-37 and the Arkansas Public Service Commission's (APSC) Resource Planning Guidelines for Electric Utilities.
EXECUTIVE SUMMARY
OG&E's 2024 IRP demonstrated the projected need for additional capacity resources at that time. OG&E issued RFPs for generation resources to address the capacity needs identified in the 2024 IRP and is in the process of finalizing contracts for selected projects. Since 2024, OG&E's capacity needs have grown further due to load growth in the OG&E service area. Looking forward, the need for investment in generation resources is likely to grow as SPP further enhances Resource Adequacy policies, regional load growth continues, and environmental regulations evolve. OG&E still has significant generation capacity needs in the near term, as shown in the table below.
OG&E's 2025 IRP Update is designed to address updated planning assumptions and present the current capacity needs. This 2025 IRP Update includes the current load forecast, several finalized SPP policy updates, and up-to-date information about environmental policy impacts.

2025 IRP Update Needs
2024 IRP Needs
SPP has recently finalized its planning reserve margin requirements between 2026 and 2029, as well as the Winter Resource Adequacy Requirement. Looking forward, further expected policy development at SPP could increase OG&E's capacity requirements. Resource Adequacy policies expected to be in place in the near future will introduce more volatility in capacity needs from year to year.
The graph below shows OG&E's capacity position including resources from executed contracts from the 2024 All Source RFP in addition to the existing capacity and capacity contributions from ongoing and future projects. The executed contracts from the RFP considerably reduce the overall capacity needs and are a significant progression towards OG&E meeting its resource adequacy requirements. OG&E will also continue negotiations with resources selected in the 2024 All Source RFP.
On March 12, 2025, the EPA announced that it would begin reconsideration of numerous regulations, including several that apply to OG&E. As potential changes to federal environmental regulations progress, OG&E continues to evaluate its compliance with existing and proposed environmental regulation and take actions if deemed necessary.
In summary, OG&E will complete the current active RFP process and continue to monitor and update planning assumptions including load forecasts, Resource Adequacy policies, and environmental regulations. OG&E will continue to pursue all options available to fully satisfy its remaining capacity needs, including through additional resources selected from the 2024 All Source RFP, future RFPs for resources as necessary to satisfy its capacity requirements, and/or other options for new capacity.
