Oklahoma natural gas customers of Summit Utilities Oklahoma could see a slight increase in rates as the firm is asking approval from the Oklahoma Corporation Commission.
Summit filed a recent request for a change in what is known as its Performance Based Rate Change Plan, based on costs it incurred in 2025.
If approved, the request would result in a monthly increase of $2.59 or 3.2% per customer in Oklahoma. The company serves 525,000 families and businesses in Oklahoma, Arkansas and the Texarkana, Texas area. It also maintains 17,000 miles of gas main pipeline in the three regions.
In its testimony on file with the Corporation Commission, the company pointed to growing 2025 costs of making “significant investments in its Oklahoma distribution system to replace an aging infrastructure under guidelines for pipeline safety.” Summit claimed it invested approximately $26.9 million in distribution mains and services. The total capital additions in mains and services was $26,989,576.
Summit is asking the regulators to approve its Return on Equity rate to 9.60% which would amount to an increase of $3.3 million. It proposed allocating 68.95% or $2,337,481 to the residential class, 14.41% or $488,515 to the General Service class, 12.32% of 4417,662 to the Commercial Service and 4.32% of $146,453 to the Large Commercial Service.
