Avista receives approval of all-party settlement in Idaho general rate case

New rates effective as of Dec. 1, 2019

/EIN News/ -- SPOKANE, Wash., Dec. 02, 2019 (GLOBE NEWSWIRE) -- Avista (NYSE: AVA) received approval from the Idaho Public Utilities Commission (IPUC or Commission) of the all-party settlement that was filed on Oct. 11, 2019, concluding the Company’s electric general rate case. New electric rates are effective as of Dec. 1, 2019.

The approved rates are designed to decrease annual billed electric revenues by $7.18 million, or 2.84%, effective Dec. 1, 2019. The approved 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.

“The Commission’s decision provides new electric rates in Idaho that are 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 make key capital investments so we can continue to provide the reliable energy our customers expect.”

Customer Electric Bills
A residential electric customer using an average of 900 kilowatt hours per month could expect to 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.

The average electric billed decreases by service schedule beginning Dec. 1, 2019 are as follows:

Rate Schedule Dec. 1, 2019 Billing Decrease
Residential Service - Schedule 1 -1.0%
General Service - Schedules 11 & 12 -8.2%
