House Bill No. 1737, known as the "Natural Gas Utility Infrastructure Cost Recovery Act of 2025," establishes a framework for natural gas utilities in Oklahoma to seek pre-approval from the Corporation Commission for investments in energy infrastructure facilities. This includes projects related to renewable natural gas, hydrogen, and other alternative fuels. The bill outlines that if the Commission determines a project serves the public interest, its costs will be subject to cost recovery rules. Additionally, any costs exceeding the approved amount by more than 10% will undergo a prudency review during the utility's next general rate filing. The Commission is required to make a decision on applications within 240 days of filing.

The bill also allows the Corporation Commission staff and the Office of the Attorney General to request assessments of specific costs associated with the analysis of applications, which will be recoverable by the natural gas utility. The Commission is tasked with promulgating rules to implement these provisions, including rules for timely cost recovery and the information required from utilities when filing applications. The act is set to take effect on November 1, 2025.
