Approval of PSO Rate Agreement Paves Way for Stronger, More Reliable Grid

TULSA, Okla. (January 15, 2025) - Public Service Company of Oklahoma (PSO) announces that the Oklahoma Corporation Commission (OCC) has issued a final order approving a settlement reached in its rate review late last year. This decision enables PSO to deliver on its commitment to provide safe, reliable, and affordable electricity for customers while modernizing and securing Oklahoma's power grid.

The approval is vital for enhancing grid resiliency and reliability, leading to shorter and less frequent outages.

"With the increasing challenges posed by Oklahoma weather and growing energy demands, PSO recognizes the need for a grid that can effectively withstand these pressures and continue to serve our communities without interruption," said PSO President and Chief Operating Officer Leigh Anne Strahler. "PSO is dedicated to ensuring that the infrastructure we provide is equipped to meet today's challenges and tomorrow's demands."

This approval reflects no change to the interim rates implemented on October 23^rd, 2024, in which the typical residential customer using 1,100 kilowatt-hours per month saw a $12 a month increase. Overall, a typical residential customer's monthly bill has gone down over the last year following a reduction of $16.93 starting in November 2024 due to lower fuel costs.

PSO is dedicated to investing in the future of energy delivery in Oklahoma and looks forward to working closely with the Oklahoman Corporation Commission and our stakeholders to ensure a safe, reliable, and affordable electricity supply for all Oklahomans.
