If approved, new rates would take effect beginning Sept. 2025 and Sept. 2026
SPOKANE, Wash., June 09, 2025 (GLOBE NEWSWIRE) -- Avista (NYSE: AVA), the Staff of the Idaho Public Utilities Commission, Clearwater Paper Corporation, Idaho Forest Group, LLC and Walmart Inc., parties to the Company's electric and natural gas general rate cases, have reached a settlement agreement that has been submitted to the Idaho Public Utilities Commission for its consideration, and which would resolve all issues in the proceeding.
If approved, the settlement agreement is designed to increase annual base electric revenues by $19.5 million or 6.3%, effective Sept. 1, 2025, and by $14.7 million or 4.5%, effective Sept. 1, 2026. For natural gas, the settlement agreement is designed to increase annual base natural gas revenues by $4.6 million or 9.2%, effective Sept. 1, 2025, and reduce base revenues by $0.2 million or 0.4%, effective Sept. 1, 2026.
The settlement capital structure includes a 9.6% return on equity (ROE) with a common equity ratio of 50% and a rate of return (ROR) on rate base of 7.28%.
'This settlement agreement will provide new rates in Idaho that are fair and reasonable for our customers, the Company, and our shareholders,' said Heather Rosentrater, Avista President and CEO. 'This is a constructive outcome. Our customers will benefit from longer recovery periods for certain deferred costs, which mitigates the bill impact of improved recovery of our costs to serve our customers. This agreement provides us with the opportunity to earn a fair return in Idaho while we invest in and maintain our infrastructure so we can continue to provide the reliable energy our customers expect.'
Residential Customer BillsIf the settlement is approved, a residential electric customer using an average of 939 kilowatt hours per month would see a 6.7% billed increase of $6.95 per month for a revised monthly bill of $111.25 effective Sept. 1, 2025, and a 4.7% billed increase of $5.22 per month for a revised monthly bill of $116.47 effective Sept. 1, 2026.
A residential natural gas customer using an average of 66 therms per month would see a billed 6.8% increase of $4.11 per month for a revised monthly bill of $64.74 effective Sept. 1, 2025, and no rate change effective Sept. 1, 2026.
