Residential customers served by Public Service Company of Oklahoma (PSO) will see a temporary increase on their electric bills beginning July 1, 2026, while the Oklahoma Corporation Commission (OCC) continues reviewing the utility’s request for a permanent rate adjustment.The interim increase will add approximately $11 per month for the average residential customer using about 1,100 kWh of electricity.
PSO is seeking approval for a larger base rate increase that would raise the average residential bill by approximately $25 per month, or about 15%. The utility says the additional revenue is needed to help cover rising costs associated with inflation, vegetation management, and major infrastructure improvements, including investments in natural gas and battery storage.
The temporary increase will remain in effect while the OCC reviews the request. If regulators approve a permanent rate that is lower than the interim amount customers are paying, PSO customers will receive a refund for the difference.
