OGE Energy Corp. operates primarily through its regulated utility subsidiary, Oklahoma Gas and Electric Company (OG&E), which provides electricity to residential, commercial, and industrial customers across a 30,000-square-mile service territory in Oklahoma and western Arkansas. The company's generation portfolio includes natural gas, coal, wind, and solar assets, supported by ongoing investments in grid modernization and reliability. Historically, OGE Energy held a significant stake in the midstream natural gas business through Enable Midstream Partners, but it fully divested this position by 2022 to focus exclusively on its core electric utility operations. Today, the company derives its revenue entirely from regulated electric utility rates and services. OGE Energy is recognized for its steady customer growth and strategic transition toward cleaner energy sources and enhanced infrastructure.
