Material Changes and Unusual Items
This filing represents NW Natural's first Washington rate case in a decade. The material change involves the formal request to recover operating costs and investments made in the Washington distribution system. Additionally, the company is proposing a decoupling tariff to mitigate earnings volatility caused by sales volume reductions due to energy conservation or weather deviations.
Guidance, Outlook, and Risks
Outlook and Timeline: The regulatory review process is anticipated to take up to 11 months. NW Natural has requested that new rates take effect on December 1, 2019.
Management Commentary: The requested rate increase is intended to recover costs and investments. The company is also seeking mechanisms to return federal tax reform benefits to customers in compliance with the Tax Cuts and Jobs Act (TCJA).
Risks and Contingencies: The filing contains forward-looking statements regarding regulatory approvals, cost recovery, and financial results. Actual results may differ materially due to inherent uncertainties in regulatory proceedings, economic conditions, and the final determination of the WUTC regarding the requested rate base, return on equity, and cost recovery mechanisms.
