OGE ENERGY CORP
OG&E submits this Integrated Resource Plan (IRP) 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 2026 IRP forecasts a need for incremental generation capacity primarily due to continued expansion of the SPP Resource Adequacy framework and continued strength in regional demand trends.
The 2026 IRP reflects OG&E's current capacity position by incorporating the most current load forecast and approved SPP policy changes. It also addresses the latest information regarding environmental regulations. SPP policies having the most impact on near-term capacity needs include completion of Planning Reserve Margin requirements through 2029, the Winter Resource Adequacy Requirement, revised resource accreditation methodologies, and the Demand Response Accreditation policy. Beginning in the Summer 2026 season, updated Resource Adequacy rules are expected to introduce greater year-to-year variability in accredited capacity requirements.
OG&E's 2024 and 2025 IRPs clearly identified additional capacity needed to support OG&E's service area as load growth has accelerated and market dynamics continue to shift. In 2024, OG&E issued multiple RFPs for new and existing generation resources, has since received regulatory approval for several projects arising from these RFP efforts, and is currently seeking regulatory approval for an additional project that resulted from these RFPs. These projects have made significant progress towards meeting capacity needs.
The graphs below show OG&E's summer and winter capacity positions including approved resources from OG&E's 2024 RFP processes, in addition to the existing resource capacity and capacity contributions from ongoing and future projects.
OG&E is seeing load growth from a diverse mix of industries, which requires a more adaptive and scalable approach to long-term resource planning. Changing SPP rules for accreditation, forecasting, outages, and Planning Reserve Margin (PRM) levels are creating a highly volatile and dynamic capacity environment that must be evaluated each season. At the same time, federal policy shifts, environmental regulations, and supply chain pressures add operational uncertainty that introduces volatility into OG&E's resource planning.

In 2025, the EPA announced it would begin reconsideration of several environmental regulations, including those affecting OG&E's existing fleet. As federal environmental policy continues to develop, OG&E will continue to evaluate compliance strategies, assess potential operational impacts, and take action as appropriate to maintain compliance with both current and proposed federal requirements.
OG&E is also monitoring other federal policies such as tax and federal import regulations that may impact resource availability.
In summary, OG&E will complete the currently active regulatory approval processes and continue monitoring and refining its planning assumptions. The Company issued two RFPs in early 2026 to address capacity needs identified in this 2026 IRP and to ensure cost-effective and reliable service for customers.
