become effective on or after January 1,2023

APPLICATIoN PAGE 1 oF 7
Boise, lD 83707
[e-mail]
In support of this Application, Intermountain alleges and states as follows.
I.
Intermountain is a gas utility, subject to the jurisdiction of the Commission, engaged in the
sale of and distribution of natural gas within the State of Idaho under authority of Commission
Certificate No. 219, issued December 2,1955, as amended and supplemented by Order No. 6564,
dated October 3,1962.
Intermountain provides natural gas service to the following Idaho communities and counties
and adjoining areas:
Ada County - Boise, Eagle, Garden City, Kuna, Meridian, and Star;
Bannock County - Arimo, Chubbuck,lnkom, Lava Hot Springs, McCammon, and Pocatello;
Bear Lake County - Georgetown and Montpelier;
Bingham County - Aberdeen, Basalt, Blackfoot, Firth, Fort Hall, Moreland/Riverside, and Shelley;
Blaine County - Bellevue, Hailey, Ketchum, and Sun Valley;
Bonneville County - Ammon,Idaho Falls, Iona, and Ucon;
Canyon County - Caldwell, Greenleaf, Middleton, Nampa, Parma, and Wilder;
Caribou County - Bancroft, Grace, and Soda Springs;
Cassia County - Burley, Declo, Malta, and Raft River;
Elmore County - Glenns Ferry, Hammett, and Mountain Home;
Fremont County - Parker and St. Anthony;
Gem County - Emmett;
Gooding County - Gooding and Wendell;
Jefferson County - Lewisville, Menan, Rigby, and Ririe;
Jerome County - Jerome;
Lincoln County - Shoshone;
Madison County - Rexburg and Sugar City;
Minidoka County - Heyburn, Paul, and Rupert;
Owyhee County - Bruneau and Homedale;
Payette County - Fruitland, New Plymouth, and Payette;
Power County - American Falls;
Twin Falls County - Buhl, Filer, Hansen, Kimberly, Murtaugh, and Twin Falls;
Washington County - Weiser.
Intermountain's properties in these locations consist of transmission pipelines, liquefied
natural gas storage facilities, compressor stations, distribution mains, services, meters and
APPLICATIoN PAGEZoF 7
regulators, and general plant and equipment. Intermountain is a wholly owned subsidiary of MDU
Resources Group, lnc. ("MDU") and shares certain centralized services provided by MDU with
other utilities also owned by MDU.
II.
lntermountain's existing base rates and charges for natural gas service were approved by the
Commissionin2}lT in Case No. INT-G-16-02 and subsequently decreased in Case No. GNR-U-
l8-01 in 2018. A copy of lntermountain's current, Commission-approved tariffs are attached as
Attachment I to this Application.
III.
A copy of the Company's tariffs showing the changes proposed in this Application are
attached as Exhibit No. 5 and the resulting clean tariffs as Exhibit No. 6 to Ms. Blattner's testimony.
Intermountain proposes to increase the revenue collected through rates by approximately
$1 I .3 million. This request represents a margin revenue increase of 10.3%, or an overall revenue
increase of 3.2o/o. The changes in rates and charges proposed in this Application are just and
reasonable. If the changes are approved as proposed, the expected rate of retum to the Company
will be approximately 7.37oh, which is a fair rate of retum on the Company's investment in property
used and useful in rendering gas utility services.
IV.
Under its presently authorized rates, the Company is earning a rate of retum of
approximately 5.20%o based on a test year ending December 31,2022. The Company seeks
additional revenues to recover increased operating expenses and costs associated with plant
additions, as well as revenues necessary to produce a fair rate of return to enable continued adequate
and reliable service. If the requested rate increases are not approved, lntermountain's rates will not
APPLICATIoN PAGE 3 oF 7
be fair, just and reasonable and Intermountain will not have an opportunity to realize a fair rate of
return on its investments in the State of ldaho.
V.
Included within the changes proposed in this Application are certain items that have been
decided or discussed in other proceedings before this Commission, such as inclusion of in-person
payment transaction fees within base rates and revisions to the Company's Line Extension tariff.
These items are discussed in Ms. Blattner's testimony.
Allocation ofthe proposed revenue increase, and associated changes to rate design, are
discussed in Mr. Amen's testimony.
VI.
To support this Application, Intermountain is concurrently filing the Direct Testimony of
Nicole Kivisto, Tammy Nygard, Ann Bulkley, Patrick Darras, Hart Gilchrist, Dyke Boese, Kirsti
Hourigan, Jacob Darrington, Ron Amen, and Lori Blaffner. This testimony and the accompanying
exhibits include information regarding the Company's finances, revenue analysis, analysis of cost of
service, and supponing work papers that justifr and support the changes proposed in this
Application. The native files for exhibits created in Microsoft Excel will be provided with or shortly
after this Application is filed.
VII.
The testimony, information, and evidence in support of the proposed changes are based on a
12-month test year ending December 31,2022. The test year consists of ninth months actual and
three months forecasted, with the forecasted months to be trued up as actual numbers become
available. lntermountain's testimony, information, and evidence regarding ratebase is presented on a
thirteen-month average basis. A complete justification of the changes proposed in this Application
APPLICATIoN PAGE 4 oF 7
is provided in this testimony and exhibits. A brief overview ofthe subject-matter of each witresses'
testimony is provided in the testimony of Ms. Kivisto.
vm.
Notice to Intermountain's customers is being accomplished by news media releases
concurrent with this Application and by an individual notice delivered to each customer. Copies of
the press release and customer notice are attached as to this Application as Attachment2 and
Attachment 3. In addition, a copy of the Application and relevant rate schedules are available on the
Company's website at www.intgas.com, and this Application and supporting materials are available
for public review on the Commission's website at www.Duc.idaho.eov
Ix.
lntermountain stands ready for an immediate hearing on this Application and requests that a
hearing be held as soon as possible.
x.
For the reasons set forth above and in the accompanying testimony and exhibits,
Intermountain respectfu lly requests:
l. That this Application be heard and acted upon at the earliest possible date;
2. That the Commission find that the Applicant's existing rates are unjust,
unreasonable and insuffrcient to provide the Company with a fair rate of retum, and that the changes
proposed in this Application are just and reasonable;
3. That the Commission approve the changes proposed in this Application, effective
January 1,2023;and
4. That the Commission grant such other relief as the Commission may determine
proper under the circumstances.

A INTERMOUNTAIN
GAs COMPANY
ASuMdiary of MDU Besrlurcx 6nD,lnc.
Intermountain Gas Company requests price increase with Idaho PUC
BOISE, lD - December 2,2022 - Intermountain Gas Company filed a request with the Idaho Public Utilities
Commission to increase its price to serve its natural gas customers. If approved, it would increase the monthly
bill for an average residential customer by about $2.19, or 4.4Yo, and for the average commercial customer by
about $3.43 , or l.5oh.
The proposed increase is for $l 1.3 million annually over current prices, or a3.2o/o overall increase. This base
price change is not impacted by changes in the cost of natural gas. The last base price increase was 2.5yo,
effective in 2017.
The primary reason for the request is due to the infrastructure investments made by the company since the last
regulatory proceeding that was filed in 2016. Intermountain's rate base, which is partially how customer prices
are determined, has grown by about $152 million since 2016, or about 640/o.
"We recognize prices have increased for many day-to-day necessities because of rising inflation since mid-
2021 ; however, a good portion of the infrastructure investments that are part of this regulatory request were
made before rising inflation," said Nicole Kivisto, president and CEO of Intermountain Gas Company. "We
believe the infrastructure investments are prudent to ensure safe and reliable natural gas service to our
customers. Current prices do not reflect the cost of providing service to our customers, which is why we are
requesting this increase."
The Idaho PUC has up to seven months to issue a decision on this request. This is just the second general price
increase request made by the company over a37-year period. The request is in regard to the cost to serve
customers and does not include the cost of natural gas, which is about 64%o of a customer's monthly bill.
Intermountain Gas encourages customers to use energy wisely. Conservation tips, information on energy
