Background
Oklahoma Gas & Electric Company (OG&E) began construction of two new power generation units (units GT1 and GT2) at its Horseshoe Lake power station in October 2024. The new gas units, designed to safely burn hydrogen when it becomes a readily available fuel source, will replace two 60-year-old units at the plant (units 6 and 7) and provide approximately 450 MW of generation capacity. The units are equipped to reduce emissions compared to the units they will replace, increase capacity and have the capability to supply power at peak times. The project had been approved by the Oklahoma Corporation Commission in 2023 to support OG&E’s growing service area. The new units are anticipated to begin providing power to customers by late 2026.[3][7]
The first shipment of the equipment (transformers) for the project took place in June 2025. The remaining equipment, including two GE Vernova gas turbines and two GE Vernova generators, will be delivered to the power station in phases throughout June, July, and August 2025.[8]
