Rate case PUD 2025-000075
- Jan 2026Filed with the commission as docket PUD 2025-000075
Public Service Company of Oklahoma filed a rate review with the Oklahoma Corporation Commission on Jan. 2, 2026, seeking a $299 million annual base-rate increase that PSO said would add about $25 a month, or 15%, to the bill of a residential customer using 1,100 kWh; it cited grid investment and growing demand. In June 2026 PSO, commission staff and other parties filed a non-unanimous partial settlement for a $73 million increase with a 9.375% return on equity, which the Attorney General says cuts the residential increase to about 1%, or $2.45 a month. Interim rates of about $11 a month for a typical residential customer took effect July 1, 2026, subject to refund. An administrative law judge's report was filed Aug. 21, 2026, and the commission had not set a decision date as of September 2026.
