[8-K] OGE ENERGY CORP. Reports Material Event

Rhea-AI Filing Summary

OGE Energy Corp., parent of Oklahoma Gas and Electric Company, announced that its utility has received pre-approval from the Oklahoma Corporation Commission to construct two natural gas combustion turbines with a total nameplate capacity of 448 megawatts at the Horseshoe Lake facility. The OCC found a need for Horseshoe Lake Units 13 and 14, scheduled to go into service by the end of 2029, approved rider recovery once they are in service, and approved two Capacity Purchase Agreements without a return on the CPAs, but did not approve Construction Work in Progress.

Following this decision, OGE Energy updated and extended its capital plan through 2030, estimating total capital expenditures of $7,285 million for 2026–2030 across transmission, Oklahoma and Arkansas distribution, generation reliability and capacity projects, and technology, fleet and facilities. The company reaffirmed a long-term consolidated earnings per share growth target of 5% to 7%, aiming for the top half of that range through 2028.

Insights

Utility sector and regulation analyst

OCC pre-approval supports OGE’s long-term gas capacity and capex plan.

The Oklahoma Corporation Commission has pre-approved construction of Horseshoe Lake Units 13 and 14, two natural gas turbines totaling 448 megawatts. This decision confirms a regulatory finding of need and allows rider recovery after the units are placed in service by the end of 2029. However, the OCC did not approve Construction Work in Progress and did not grant a return on the two Capacity Purchase Agreements, which shapes how cash recovery will occur over time.

OGE Energy has updated and extended its capital plan through 2030, outlining planned capital expenditures of $7,285 million for the years 2026–2030. Spending is spread across transmission, Oklahoma and Arkansas distribution, generation reliability and capacity projects, and technology, fleet and facilities. Management reiterates a long-term consolidated earnings per share growth target of 5% to 7%, targeting the top half of that range through 2028, tying growth expectations to this large, largely regulated investment program.

Item 8.01. Other Events

OGE Energy Corp. ("OGE Energy") is the parent company of Oklahoma Gas and Electric Company ("OG&E"), a regulated electric company with approximately 910,000 customers in Oklahoma and western Arkansas.

OGE Energy today reported that OG&E has received pre-approval by the Oklahoma Corporation Commission (“OCC”) to construct two natural gas combustion turbines with a total nameplate capacity of 448 megawatts at its Horseshoe Lake facility in Oklahoma.

On November 13, 2025, the OCC issued an order finding that OG&E has demonstrated a need to construct Horseshoe Lake Units 13 and 14, which are scheduled to go into service by the end of 2029, but did not approve the use of Construction Work in Progress. The OCC order did approve rider recovery for the Horseshoe Lake Units 13 and 14 once they are placed in service, approved two Capacity Purchase Agreements ("CPAs"), but did not approve a return on the CPAs. As a result of receiving pre-approval, OGE Energy has updated its five-year capital plan, including the addition of Horseshoe Lake Units 13 and 14, as well as extended its capital plan through 2030. OGE Energy expects to finance these incremental investments with a mix of debt and equity content to support strong investment grade credit ratings and targeted credit metrics. OGE Energy's long-term consolidated earnings per share growth target is five percent to seven percent, targeting the top half of the range through 2028.

The following table presents OGE Energy's estimates of capital expenditures for the years 2026 through 2030. OGE Energy will continue to update estimates of capital expenditures as customers are added and the service territory continues to grow.
