SPOKANE, Wash., Dec. 23, 2024 (GLOBE NEWSWIRE) -- Avista's (NYSE: AVA) electric and natural gas general rate cases filed in January 2024 have concluded, with an order from the Washington Utilities and Transportation Commission (Commission) approving a two-year rate plan that will change electric and natural gas rates, beginning Jan. 1, 2025, and Jan. 1, 2026.

For electric operations, the Commission approved rates designed to provide a 0.1 percent, or $0.8 million increase in base revenue for Rate Year 1, and a 11.6 percent, or $68.9 million increase in base revenue for Rate Year 2. For natural gas operations, the Commission approved rates designed to provide a 11.2 percent, or $14.2 million increase in base revenue for Rate Year 1, and a 2.8 percent, or $4.0 million increase in base revenue for Rate Year 2.

For electric Rate Year 1, it is our belief that there is a calculation error with respect to the level of power supply expenses removed from the final revenue requirement, that, if corrected, would move the revenue approved from $0.8 million to approximately $12 million. We have brought this issue to the attention of the Commission. When this correction is made, the base percentage increase will be 2.0 percent.

The Commission approved a rate of return (ROR) on rate base of 7.32 percent, with a common equity ratio of 48.5 percent and a 9.8 percent return on equity (ROE), noting that an upward adjustment is needed to address the challenges the Company faces. The Commission did not, at this time, support a change to the mechanics of the Energy Recovery Mechanism (ERM), but did continue its support for important mechanisms such as Wildfire and Insurance balancing accounts, and decoupling.

While the Commission did not approve a modification to the existing ERM, the forecasted power supply costs that were removed from Electric Rate Year 1, which makes up the majority of the reduction in revenue from the Company’s filed case, to the final order, would flow through the ERM deadband and sharing bands.

"We are pleased with the Commission’s constructive decision, which provides a positive outcome for both our customers and our shareholders. Our Washington electric customers will receive the benefit of Avista's reduced power supply cost in Rate Year 1, mitigating the impact to their bills. At the same time, our shareholders will benefit from the increase in margin, improving the return for our shareholders. The decision reflects the Commission’s recognition of Avista's investment in utility infrastructure to benefit our customers, and that our operating expenses are increasing at a faster pace than revenues. The outcome provides for necessary recovery of the costs to serve our customers and continued investment in our systems," said Dennis Vermillion, chief executive officer of Avista Corp.
