Oklahoma Natural Gas (ONG) is seeking a $28.7M base rate hike, which could impact customers across the state. The company, a division of ONE Gas, Inc., has filed an application with the Oklahoma Corporation Commission requesting review and approval under its performance-based rate plan. The increase is intended to help recover rising business costs and fund continued investment in natural gas infrastructure. If approved, it would result in an estimated $2.73 per month for average residential customers and $0.42 for low-income customers. The case will undergo a public hearing on June 11, 2026. The final decision on the rate increase will be made after a hearing.
