Segment Reporting [Abstract] |
Report of Business Segments | 12. Report of Business Segments OGE Energy reports its operations primarily through a single segment, captioned "electric company," which is engaged in the generation, transmission, distribution and sale of electric energy. The "other operations" caption primarily includes the operations of the holding company and other energy-related investments. Intersegment revenues would be recorded at prices comparable to those of unaffiliated customers and could be affected by regulatory considerations. In accordance with ASC Topic 280, “Segment Reporting,” the Registrants have identified their Chief Executive Officer as the “chief operating decision maker.” The Chief Executive Officer uses net income as the measure of reportable segment profit or loss to make operating decisions, allocate resources, and assess performance. The following tables, which include significant segment expenses, present the results of OGE Energy's business segments for the years ended December 31, 2024, 2023 and 2022.

(A) During 2022, OGE Energy held an investment in Energy Transfer's equity securities and reported the investment's activity, as well as Enable legacy pension and postretirement costs, through the natural gas midstream operations segment. As of the end of September 2022, OGE Energy sold all of Energy Transfer's limited partner units; therefore, beginning in 2023, OGE Energy no longer has a natural gas midstream operations segment.
