Avista reaches multiparty settlement of all issues in Washington general rate case

SPOKANE, Wash., June 28, 2022 (GLOBE NEWSWIRE) -- Avista (NYSE: AVA) and certain parties to the company’s electric and natural gas general rate cases have reached a settlement agreement that has been submitted to the Washington Utilities and Transportation Commission (UTC or Commission) for its consideration. If approved, new rates would take effect in Dec. 2022 and Dec. 2023.

In addition to Avista, the parties to the electric and natural gas rate cases include the Staff of the UTC, the Public Counsel Unit of the Washington Attorney General’s Office (Public Counsel), the Alliance of Western Energy Consumers, the NW Energy Coalition, The Energy Project, Walmart, Sierra Club, and Small Business Utility Advocates. All parties, apart from Public Counsel, agreed on the terms of settlement of all issues in Avista’s general rate case.

The settlement includes, among other things, agreement on electric and natural gas revenue requirement increases for both years of the multi-year rate plan. The recommendation to the Commission by the Staff of the UTC or other parties to approve the multiparty settlement is not binding on the Commission itself.

If approved, the settlement agreement is designed to increase annual electric revenues by $38 million effective in Dec. 2022 and $12.5 million effective in Dec. 2023 and increase annual natural gas revenues by $7.5 million effective in Dec. 2022 and $1.5 million effective in Dec. 2023. To mitigate the overall impact of the revenue increases on customers, concurrent with the effective date of this rate case, the settling parties agreed to offset part of the 2022 base rate request with a Residual Tax Customer Credit. The estimated benefits of $27.6 million for electric customers and $12.5 million for natural gas customers will be incrementally returned over a two-year period from Dec. 2022 – Dec. 2024.

The electric and natural gas requests are based on a proposed rate of return (ROR) of 7.03% but the parties did not otherwise agree on an explicit return on equity, cost of debt, or capital structure.

“We are pleased that the parties were able to reach a joint recommendation to the Commission in this case,” said Dennis Vermillion, Avista president and CEO. “If approved, this outcome provides a positive framework for our Washington operations that benefits both our customers and shareholders. We take our responsibility to provide safe, reliable energy at an affordable price very seriously, and we have and will continue to work hard to manage our costs and identify ways to best serve our customers that contribute to keeping energy prices affordable.”

Other Settlement Items
The settlement agreement also addresses several other items, including modifications to the Company’s low-income rate assistance programs, implementation of an insurance expense balancing account to address the volatility of insurance costs, tracking of certain performance metrics, changes to the Company’s natural gas line extension policies, and the cost recovery associated with the Dry Ash Disposal System project at the Colstrip Power Plant. While Avista believes this investment is prudent, the settlement agreement results in a one-time write-off in 2022 of $4.0 million by excluding the project from customer rates.
