Filing UE - 220232

Company: Avista Corporation
DBA: Avista Utilities
Filing Type: Staff Investigation
Case Status: Closed
Dates (Opened & Effective): 03/31/2022 & 12/24/2024
Summary: Annual filing by Avista Corporation to review and confirm power cost deferrals in the 2021 Energy Recovery Mechanism. In sum, power costs were higher than the 2021 baseline by approximately $16.4 million. This was primarily due to the extreme heat event in the summer of 2021 as well as unfavorable hydrogeneration conditions. The Company proposes to increase the deferral account in the surcharge direction by approximately $8.8 million which includes $97,357 in interest. Combined with the -$13,157,482 deferral balance approved for 2019-2020 but not approved for rebate, the total balance approved for prudency, but not yet approved for rebate would be -$4,335,413 in the rebate direction. This balance would not result in any rate changes at this time.
