Northwest Natural Gas Company, a subsidiary of Northwest Natural Holding Company, has filed a general rate case with the Public Utility Commission of Oregon, seeking an annual revenue requirement increase of $59.4 million. On June 23, 2025, a stipulation was filed with the Commission by NW Natural and various parties involved, addressing certain issues in the case. This agreement provides for a total revenue requirement increase of $21.3 million over existing rates, contingent upon the completion of specified capital projects. The new rates are expected to be effective by October 31, 2025, pending approval. The expected rate base as of November 1, 2025, is projected to be $2.234 billion, marking an increase since the last rate case. The stipulation accounts for a capital structure with an equal split between common equity and long-term debt, with a return on equity set at 9.50%.
