Avista reaches all-party settlement in Idaho general rate case

If approved, new rates would take effect beginning Dec. 1, 2019

/EIN News/ -- SPOKANE, Wash., Oct. 11, 2019 (GLOBE NEWSWIRE) -- Avista (NYSE: AVA) and all parties to the company’s electric general rate case have reached a settlement agreement that has been submitted to the Idaho Public Utilities Commission (IPUC or Commission) for its consideration. If approved, new rates would take effect Dec. 1, 2019.

If approved, the settlement agreement is designed to decrease annual billed electric revenues by $7.18 million, or 2.84%, effective Dec. 1, 2019. The settlement revenue decreases are based on a 9.5% return on equity (ROE) with a common equity ratio of 50% and a rate of return (ROR) on rate base of 7.35%, which is a continuation of current levels. This outcome is in line with the Company’s expected margin in this case.

“We’re pleased to pass the benefits of this settlement agreement to our customers during the heating season. This settlement agreement will provide new rates in Idaho that are fair and reasonable for our customers, the Company and our shareholders,” said Dennis Vermillion, Avista president and CEO. “This outcome provides us the opportunity to continue to earn a fair return in Idaho and supports Avista’s efforts to invest in and maintain our infrastructure so we can continue to provide the reliable energy our customers expect.”

The primary element of the difference in the agreed upon base revenues in the settlement agreement from Avista’s original request is the continued recovery of costs for Avista’s wind generation power purchase agreements, which will include Palouse Wind and Rattlesnake Flat, through the Power Cost Adjustment (PCA) mechanism rather than through base rates. 

Residential Customer Electric Bills
If the settlement is approved, a residential electric customer using an average of 900 kilowatt hours per month would see a billed decrease of $0.86 per month, or 1.0%, for a revised monthly bill of $84.45, effective Dec. 1, 2019.

The actual percentage rate change will vary by customer class and will depend on how much energy a customer uses.

Avista serves more than 133,000 electric customers in Idaho.

Avista’s Original Request
Avista’s original request included an increase of annual electric billed revenues by $5.3 million or 2.1%, effective Jan. 1, 2020.

The electric request was based on a proposed rate of return (ROR) on rate base of 7.55% with a common equity ratio of 50% and a 9.9% return on equity (ROE).
