Commoditv Costs
In CaseNo. AVU-G-21-04, the Commission approved the Company's annual PGA with a September 1,
2021 effective date. In that filing, the Company's commodity weighted average cost of gas
("Commodity WACOG") increased by $0.04022 per therm, from $0.16283 per thenn to $0.20305 per
therm (including revenue sensitive costs). Subsequently, in Case No. AVU-G-21-07, the Commission
approved the Company's proposed "out-of-cycle" PGA adjustment to the commodity weighted average
cost of gas ("Commodity WACOG") included in Schedule 150 by $0.06235 per thenn, from $0.20305
per therm to $0.26540 per therm (including revenue sensitive costs) effective February 1,2022.
Since that time, the price of wholesale natural gas has continued to rise, with prices reaching levels not
seen in over 13 years. The market factors atfibuting to the rise in prices are an overall increase in
demand, lower supply, and more recently the impact that the global natural gas market is having on the
US natural gas market due to the war in Ukraine. The increase in demand for natural gas has been due
to elevated liquified natural gas (LNG) exports, which have been running at or near capacrty throughout
the winter, and use for electric generation remaining elevated. Historically, when natural gas prices reach
high levels, there is a reduction in demand for its use in power generation, however, with the two main
alternative fuels (coal and oil) also being priced at extremely high levels, this has not occurred. On the
supply side, production has been slow to ramp up to pre-pandemic levels and production has
underperformed expectations n2022. The increased demand and lack of supply has also led to storage
balances being well below historical levels. Although the US natural gas market is not directly connected
to the European market except through LNG exports, which as mentioned are already operating at
capacity, there is likely some risk premium being priced into the US market based on the expectation
that world energy prices will remain elevated. Some of these market conditions were present when the
Company made its filings n 2021, but when coupled with the additional market factors increasing
demand for natural gas, there has been additional upward pressure on wholesale natural gas prices, thus
creating a material change from the WACOG approved in the Company's prior PGA. Avista is
proposing a rate adjustrnent that more closely aligns the actual cost of what Avista is paying for natural
gas with what is included in customer rates in this frling.
As a result of the changes in pricing in the wholesale markets, the Company proposes to increase the
Commodity WACOG from the $0.26540 per therm embedded in current rates to $0.35181 per therm,
representing an increase of $0.08641 per therm. Making this filing now results in limiting the surcharge
deferral for the remainder of the PGA year and allows the Company to re-evaluate the estimated
commodity WACOG based on updated market prices when we make our annual fullPGA filing in the
3rd Quarter of 2022.
CaseNo. AVU-G-22-0 Page 3 of5
The Company calculated the proposed Commodity WACOG of $0.35181 per themr by adjusting just
two items. First, the Company used a 30-day historical average of AECO forward prices (as of April
12,2022) to develop an estimated cost associated with index purchases for the one-year period beginning
after the effective date. The estimated monthly volumes to be purchased during this period are multiplied
by the 30-day average forward price for the corresponding month. The annual weighted average price
for these volumes is $4.21 per dekatherm ($0.421 per therm). The annual weighted average price
presently included in rates for these volumes is $3.06 per dekatherm ($0.306 per therm).
Second, the Company entered into additional natural gas hedges after it filed its last PGA Commodity
WACOG update. The weighted average price for hedged natural gas presently included in rates is $2.66
per dekatherm ($0.266 per therm). The annual weighted average price for all hedges during the period,
including those entered into after the annual PGA filing, is now $2.90 per dekatherm (0.290 per therm).
Updating the 30-day historical average of forward wholesale natural gas prices, and reflecting all hedges
entered into to date for the period, results in a proposed $8.3 million annual revenue increase.
x.
Demand Costs
The Company is not requesting any changes related to demand charges in this filing. Any changes to
those items will occur in the Company's next annual PGA filing.
xI.
Schedule 155 / Amortization Rate Change
The Company is not requestrng any changes related to Rate Schedule 1S5/Amortization charges in this
filing. Any changes to those items will occur in the Company's next annual PGA filing.
XII.
If approved as filed, the Company's annual revenue will increase by approximately $8.3 million or about
10.5% effective July 1, 2022. Residential or small commercial customers using an average of 63 therms
per month would see an increase of $5.44 per month, or approximately 9.7%o. The present bill for 63
therrrs is $55.86 while the proposed bill is $61.30.
xrII.
Confidential Exhibit "D" attached hereto contains supponing workpapers for the rates proposed by
Applicant contained in Exhibit "A".

Avista requests that the rates proposed in this filing be approved to become effective on July 1,2022,
and requests that the matter be processed under the Commission's Modified Procedure rules through the
use of written comments. Avista stands ready for immediate consideration on its Application.
Case No. AW-G-22-0 Page 4 of5
XV
WHEREFORE, Avista requests the Commission issue its Order finding its proposed rates to be just,
reasonable, and nondiscriminatory and to become effective for all natural gas service on and after July
1,2022. The overall increase is approximately $8.3 million or L0.5o/o. The Company requests that the
matter be processed under the Commission's Modified Procedure rules through the use of written
comments.

DRAFT
Important Notice for Idaho Customers
(May 2022)
Avista has frled a Purchased Gas Cost Adjustment (PGA) rate adjustmant request with the Idaho Public
Utilities Commission (Commission), that if approved, is designed to increase overall natural gas revenue
by approximately $8.3 million or 10.5% effective July 1, 2022. Tltis filing has no impact on Avista's
earnings.
The PGA is typically filed annually to balance the actual cost of wholesale natural gas purchased by
Avista to serve customers with the amount presently included in customer's rates. PGAs ensure that
customers pay what Avista pays for natural gas, only at a more predictable and stable rate throughout the
year.
Since the last PGA was filed in late 202l,the price of wholesale natural gas has continued to rise. Due to
this increase of wholesale natural gas prices, Avista is proposing a rate adjustment that more closely
aligns the actual cost of what Avista is presently payrng for wholesale natural gas with the cost of
natural gas included in customer rates.
About 40Yo of an Avista natural gas customer's bill is the combined cost of purchasing natural gas on the
wholesale market and tansporting it to Avista's systan. These costs fluctuate up and down based on
market prices, of which Avista cannot control. lmportantly, Avista does not make a profit on, or
markup, the wholesale cost of natural gas; what Avista pays is what is passed through to customers, dollar
for dollar.
Natural Gas Customer Bills
If approved, residential natural gas customers in Idaho using a monthly average of 63 therms would see
their bills increase $5.44 or approximately 9.7Yo, from $55.86 to $61.30 per month effective July 1,2022.

FOR AVISTA CORPORATION
I, David J. Meyer, represent Avista Corporation. I am Vice President and Chief
Counsel for Regulatory and Governmental Affairs for Avista Corporation (Avista or
Company) and I an appearing on its behalf in this proceeding.
I make this certification and claim of confidentiality pursuant to IDAPA 31.01.01
because Avista, through its supporting workpapers, is disclosing certain information that
is CONFIDENTIAL and constitutes TRADE SECRETS as defined by Idaho Code
Section 9-340 and 48-801 and protected under IDAPA 31.01.01.067 and 31.01 .01.233.
The electonic information Avista provides will, as required under IDAPA Rule
31.01.01.067, be marked as CONFIDENTIAL on all documents. [n accordance with
Case No. GNR-U-20-01, OrderNo.34602 which suspends the requirement to physically
file documents due to the COVID-l9 Pandemic, the Company will file all workpapers,
tariffs, and exhibits only in electronic format.
The confidential information that Avista is disclosing includes, but is not limited
to certain forward wholesale natural gas pricing which is provided by a third-party
vendor, who does not allow public access to their proprietary information. Avista herein
asserts that the aforementioned information is confidential in that making third-party
pricing data public will violate the terms of our agreement with the vendor.
I am of the opinion that this information is CONFIDENTIAL, as defined by
Idaho Code Sections 9-340D and 48-801, should therefore be protected from public
inspection, examination and copying, and should be utilized only in accordance with the

Avista Makes Natural Gas Price Adjustment Request in Washington
and ldaho
Overall changes in naturalgas prices would be effective July 1, 2022
SPOKANE, Wash. April29, 2022,4:05 p.m. PST: Avista (NYSE: AVA) has made Purchased
Gas Cost Adjustment (PGA) filings with the utility commissions in Washington and ldaho that, if
approved, are designed to increase overallnaturalgas revenue 12.60/o and 10.5%, respectively,
effective July 1 ,2022. These filings have no impact on Avista's earnings.
PGA requests are $pically filed annually to balance the actual cost of wholesale natural gas
purchased by Avista to serve customers with the amount presently included in customeds rates.
Avista does not make a profit on, or markup, the wholesale cost of natural gas; PGAs ensure
customers pay what Avista pays, dollar for dollar, only at a more predictable and stable rate
throughout the year.
Since the last PGA filings were made, the price of wholesale natural gas has continued to rise
with dramatic sustained increases since late March, with prices reaching levels not seen in over
13 years. About 40o/o 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.
As the effects of inflation impact the entire country, the cost of doing business is going up for all
companies and industries. This filing is an effort to incrementally align customers' rates with the
market conditions for predictability.
Natura! Gas Customer Bills
Washington: lf approved, residential natural qas customers using an average of 67 therms per
month would see their monthly bills change from $64.86 to $72.66, an increase of $7.80 per
month, or approximately 1 1.7o/o.
The percentage change varies by rate schedule and is dependent upon how much energy
customers on the respective rate schedules use. lf approved, natural gas customers would see

DRAFT
Important Notice for Idaho Customers
odty 2022)
Avista has filed a Purchased Gas Cost Adjustment (PGA) rate adjustment request with the Idaho Public
Utilities Commission (Commission), that if approved, is designed to increase overall natural gas revenue
by approximately $8.3 million or 10.5% effective July l, 2022. T\is filing has no impact on Avista's
earnings.
The PGA is typically filed annually to balance the actual cost of wholesale natural gas purchased by
Avista to serve customers with the amount presently included in customer's rates. PGAs ensure that
customers pay what Avista pays for natural gas, only at a more predictable and stable rate throughout the
year.
Since the last PGA was filed in late 202l,the price of wholesale natural gas has continued to rise. Due to
this increase of wholesale natural gas prices, Avista is proposing a rate adjustment that more closely
aligns the actual cost of what Avista is presently paying for wholesale natural gas with the cost of
natural gas included in customer rates.
About 40Yo 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, of which Avista cannot control. lmportantly, Avista does not make a profit on, or
markup, the wholesale cost of natural gas; what Avista pays is what is passed through to customers, dollar
for dollar.
Natural Gas Customer Bills
If approved, residential natural gas customers in Idaho using a monthly average of 63 therms would see
their bills increase $5.44 or approximately 9.lYo, from $55.86 to $61 .30 per month effective luly 1,2022.
