Avista Makes Natural Gas Price Adjustment Filings in Idaho Overall changes in natural gas prices would be effective Sept. 1, 2021

July 2, 2021

SPOKANE, Wash. – July 2, 2021:  Avista (NYSE: AVA) has made two rate adjustment filings with the Idaho Public Utilities Commission (IPUC or Commission) that, if approved and when combined, are designed to increase overall natural gas revenue by approximately $7.1 million or 10.6% effective Sept. 1, 2021. These filings have no impact on Avista’s earnings.

These rate adjustment filings are separate and distinct from the Settlement Stipulation filed on June 14, 2021 related to the pending general rate case filing, that, if approved, would reduce customer’s natural gas bills by an overall 4.5%, also on Sept. 1, 2021.

Natural Gas Adjustment Filings
The first adjustment is the annual Purchased Gas Cost Adjustment (PGA) filing. If approved, Avista’s request is designed to increase annual natural gas revenues by approximately $9.0 million or 13.5% effective Sept. 1, 2021.  

The PGA is filed each year to balance the actual cost of wholesale natural gas purchased by Avista to serve customers with the amount included in rates. This includes the natural gas commodity cost as well as the cost to transport natural gas on interstate pipelines to Avista’s local distribution system. The increase is primarily driven by two factors: 1) wholesale natural gas costs that are higher than the level presently included in rates, and 2) the expiration of a rebate customers are currently receiving from last year’s PGA. About 30% of an Avista natural gas customer's bill is the combined cost of purchasing natural gas on the wholesale market and transporting it to Avista's system. These costs fluctuate up and down based on market prices and are not marked up by Avista. The remaining 70% covers the cost of delivering the natural gas -- the equipment and people needed to provide safe and reliable service.

The second filing is the Deferred Balances Credit filing.  If approved, Avista’s request is designed to decrease natural gas revenues by approximately $1.9 million or 2.9% effective Sept. 1, 2021.  The Deferred Balances Credit filing is comprised of the following items:

•    Natural Gas Deferred Depreciation Expense balance of $900,000. This is a result of the Company deferring the benefit of reduced natural gas depreciation expense recorded on its books of record, but not yet reflected in its natural gas customer rates.
•    Accumulated Funds Used During Construction (AFUDC) Deferral balance of $393,000. AFUDC tax flow-through deferral balances are a result of changing how taxes are recognized for rate making purposes. 
•    CARES Act Deferral balance of $648,000. The CARES Deferral balance is a result of Avista deferring the tax benefits associated with the CARES Act, which allowed companies with taxable net operating losses (“NOL”) for years 2018 through 2020 to carry those losses back to the five previous tax years. 

Customer Bills Resulting from these Filings
If the natural gas PGA and Deferred Balances Credit filings are approved, residential natural gas customers in Idaho using an average of 63 therms per month would see their monthly bills increase from $49.49 to $54.05, an increase of $4.56 per month, or approximately 9.2%. The proposed natural gas rate changes would be effective Sept. 1, 2021. 

The net effect, on an annual revenue basis, for the requested natural gas rate changes by rate schedule are:     
General Service - Schedule 101                               9.2%
Large General Service - Schedules 111 & 112     16.3%
Transportation Service - Schedule 146                 -2.9%
Overall                                                                       10.6%
