On July 2, 2021, Avista Corporation dba Avista Utilities (“Company”) applied for an
Order Approving a Change in Natural Gas Rates and Charges to Rebate Certain Deferred Credit
Balances asking to decrease its annualized revenues by about $1.9 million (2.9%). Application at
1. The Company proposes to refund to customers deferred credit balances associated with
depreciation expense, Allowance for Funds Used During Construction (“AFUDC”), and the
Coronavirus Aid, Relief, and Economic Security (“CARES”) Act benefits.
The Company said its proposal, if approved, will decrease rates for an average
residential or small commercial customer using an average of 63 therms per month by $1.44 per
month (2.9%). Id. The Company states it provided notice of this Application to its customers in
compliance with Commission authorities. Id. at 2. The Company asks that the Application be
processed by Modified Procedure, and that the new rates take effect September 1, 2021. Id. at 1.
On July 27, 2021, the Commission issued a Notice of Application, Notice of Modified
Procedure and Order setting comment deadlines for interested persons and a reply comment
deadline for the Company. See Order No. 35117. The Commission Staff (“Staff”) filed comments

Now, based on the record, the Commission approves the Application as set forth below.
THE APPLICATION
The Company’s proposed refund to customers of deferred credit balances would offset
the Company’s proposed Purchased Gas Cost Adjustment (“PGA”) rate increase in its application

supports the Company’s proposal to return to natural gas customers in Idaho approximately $1.9
million of deferred credits. After examining the Company’s Application, prior Orders, and
reviewing the deferral balances, Staff recommended the Commission approve the Company’s
proposed Tariff Schedule 178 and set the rebate rates as set forth in the Company’s Application.
COMMISSION FINDINGS AND DECISION
The Commission has reviewed the record, including the Application and comments.
The Company is a gas corporation and public utility, and the Commission has jurisdiction over it
and the issues in this case under Title 61 of the Idaho Code, and more specifically, Idaho Code §§
61-117, 61-129, 61-307, 61-501, and 61-502. The Commission must establish just, reasonable,
and sufficient rates for utilities subject to its jurisdiction. Idaho Code § 61-502. The Commission
must establish just, reasonable, and sufficient rates for utilities subject to its jurisdiction. Idaho
Code § 61-502.
Based on our review of the record, we find the Company’s proposal to refund to
customers deferred credit balances associated with depreciation expense, AFUDC, and CARES
Act benefits totaling $1,935,000 to be fair, just, and reasonable. The Commission approves the
Company’s proposed Schedule 178 containing rates that will be used to refund the deferred credit
balances to the Company’s customers. Approval of the Company’s Application to refund deferred
credit balances to customers comes at an opportune time as this will help to mitigate the rate
impacts of the Company’s PGA adjustments approved by Order No. 35151.
