CASE NO. |PC-E-22-11
APPLICATION
ldaho Power Company ("ldaho Powe/'or "Company"), in accordance with ldaho
Code S 61-502 and RP 052, hereby respectfully requests the Idaho Public Utilities
Commission ("Commission") approve an update to Schedule 55 based on the
quantification of the 2022-2023 Power CostAdjustment ('PCA') to become effective June
1, 2022, for the period June 1 , 2022, through May 31 , 2023. lf the proposed rates and
charges for electric service in the state of ldaho included as Attachment 1 to this

APPLICATION - 1
ln support of this Application, ldaho Power has filed the Direct Testimony of
Jessica G. Brady, Regulatory Analyst. Ms. Brady's testimony details the 2022-2023 PCA
amount, explains the factors that impact this yea/s PCA quantification, details the
calculation of the proposed 2022-2023 PCA rates, and discusses the additional PCA
component related to revenue sharing.
I. BACKGROUND
1. ldaho Power is an ldaho corporation whose principal place of business is
1221West ldaho Street, Boise, ldaho 83702.
2. ldaho Power is a public utility supplying retail electric service to more than
600,000 customers in southern ldaho and eastern Oregon. ldaho Power is subject to the
jurisdiction of this Commission in ldaho and to the jurisdiction of the Public Utility
Commission of Oregon. ldaho Power is also subject to the jurisdiction of the Federal
Energy Regulatory Commission.
3. On March 29, 1993, by Order No. 24806 issued in Case No. IPC-E-92-25,
the Commission approved the implementation of an annual power cost adjustment
procedure in order to provide consistency and stability to rates. The PCA is a cost
recovery mechanism that passes on both the benefits and costs of supplying energy to
ldaho Power customers. Neither ldaho Power nor its shareholders receive any financial
return on this filing - money collected from the surcharge can be used only to pay power
supply expenses.
4. On January 9, 2009, by Order No. 30715 issued in Case No. IPC-E-08-19,
the Commission approved certain changes to the PCA mechanism, including a g5
percenU5 percent sharing mechanism between customers and the Company. Order No.
APPLICATION - 2
30715 also approved changes to the Load Growth Adjustment Rate ('LGAR"), third-party
transmission expense, the PCA forecast, and power supply expense distribution.
5. On January 13,2010, the Commission issued Order No. 30978 in Case No.
IPC-E-09-30 approving the settlement stipulation filed in lieu of a general rate case.
Through this stipulation, a revenue sharing mechanism was established to allow the
Company to accelerate the amortization of accumulated deferred investment tax credits
if the Company's actual ldaho jurisdictional year-end Return on Equity ('ROE') fell below
9.5 percent in any fiscal year from 2009 through 2011. This mechanism also included a
provision for revenue sharing if the Company's actua! ldaho jurisdictional year-end ROE
exceeded 10.5 percent in any year during the same three-year period. Per the terms of
the stipulation, 50 percent of the ldaho jurisdictional year-end ROE in excess of 10.5
percent was to be shared with customers in the form of a rate reduction. The revenue
sharing percentages, thresholds, accounting, and duration were subsequently modified
by Order Nos. 32424, 33149 and 34071.
6. On March 15,2011, the Commission issued Order No. 32206 in Case No.
GNR-E-10-03 adopting a revised LGAR methodology and changing the name of the
methodology to the Load Change Adjustment Rate (.LCAR").
7. On May 28, 20'15, the Commission issued Order No. 33307 in Case No.
IPC-E-15-15 converting the LCAR to a Sales Based Adjustment ('SBA") rate, as well as
modifying the PCA deferral balance's monthly interest calculation. Per Order No. 33307,
the SBA rate is calculated in the same manner as the LCAR, with the only modification
being the replacement of the load-based megawatt-hour ("M\ffh") denominator with the
corresponding sales-based MWh denominator. Second, the Order required the Company
APPLICATION - 3
to calculate monthly interest on the deferral balance by assigning annual base Net Power
Supply Expense ("NPSE") to each month according to expected base rate revenue
collection as set in the Company's last general rate case, Case No. !PC-E-11-08.
8. On May 31, 2018, the Commission issued Order No. 34071 in Case No.
GNR-U-18-01 approving the current iteration of the revenue sharing mechanism. This
order accepted the settlement stipulation filed on April 12, 2018, extending the revenue
sharing mechanism indefinitely and modifoing portions of the previous accounting order.
More specifically, Order No. 34071 approved modifications to the sharing portion of the
mechanism, which allowed for greater customer benefits. First, for actual year-end ldaho
jurisdictional earnings greater than 10 percent ROE, all amounts up to and including 10.5
percent ROE will be shared between customers and the Company on an 80 percent and
20 percent basis, respectively. The customer revenue sharing benefit wil! be in the form
of a reduction to rates at the time the subsequent year's PCA becomes effective. Second,
ldaho earnings above a 10.5 percent ROE will also be shared, with customers receiving
55 percent of the earnings in the form of a reduction to rates at the time the subsequent
year's PCA becomes effective, as well as 25 percent of the earnings applied as an ofbet
to the Company's pension balancing account, with the Company retaining the remaining
20 percent.
9. On May 28, 2021, the Commission instructed ldaho Power 'to initiate
discussions with interested parties and to file a case with the Commission to review
whether the PCA mechanism should be modified" before the Company files its PCA
application in April 2022. Order No. 35054. On January 10, 2022, the Commission issued
Order No. 35290 in Case No. IPC-E-2'!-18 approving a modification to the PCA filing to
APPLICATION - 4
replace the "true-up" and "true-up of the true-up" with a single balancing account referred
to below as the "Balancing Adjustment." This modification does not materially affect the
overall cost recovery of the PCA.
il. 2022-2023 PCA CALCULATTON
10. The PCA is a rate mechanism that quantifies and tracks annual differences
between actual NPSE and the normalized or "base level" of NPSE recovered in the
Company's base rates for recovery or credit through an annual rate change on June 1.
The PCA is also the rate mechanism used by the Company to provide direct revenue
sharing benefits resulting from the revenue sharing mechanism approved in Order No.
u071.
11. The PCA mechanism utilizes a 12-month test period of April through March
('PCA Year") and consists of a forecast component and a Balancing Adjustment. The
PCA forecast component is based on the Company's March Operating Plan and
represents the difference between the NPSE forecast in the March Operating Plan and
the base level NPSE recovered in the Company's base rates. The Balancing Adjustment
includes a backward-looking tracking of differences between the prior PCA Yea/s
forecast and actual NPSE incurred by the Company, and also tracks the collection of the
prior year's Balancing Adjustment.
12. \Mth the exception of Public Utility Regulatory Policies Act of 1978
CPURPA") expenses and demand response incentive costs, the PCA allows the
Company to pass through to ldaho customers 95 percent of the annual differences in
actual NPSE as compared to the base level NPSE, whether positive or negative.
APPLICATION - 5
13. Forecast. The testimony of Ms. Brady describes and computes the PCA
rate to be effective June 1, 2022, through May 31 , 2023. The system-level forecast of
NPSE for the 2022-2023 PCA Year is $498,834,556, which is $193,149,687 higher than
the currently approved base level NPSE of $305,684,869. The 2022-2023 PCA forecast
component to be collected from ldaho customers is $178,795,145. As described in the
testimony of Ms. Brady, the system-level forecast of NPSE for the 2022-2023 PCA Year
is $56,477,149 higher than last year's forecast amount of $442,357,407. This year, due
to an expected reduction in hydro generation and increase in both naturalgas prices and
market energy prices, the Company expects to increase coal generation for load service
as well as off-system surplus sales.
14. Balancino Adiustment. Per Order 35290, the'true-up" and the "true-up of
the true-up" have been combined into a single Balancing Adjustment. !n addition to the
NPSE incurred during the April 2021 through March 2022 period, ldaho Power included
its actual cost of Western Energy lmbalance Market ("ElM') participation for April 2021
through March 2O22in the Balancing Adjustment as approved by Commission Order No.
34100. Benefits associated with EIM participation are embedded in actual NPSE
experienced over that same period.
15. The PCA Balancing Adjustment deferral balance at the end of March 2022,
with interest applied, was approximately $38.7 million. This balance was primarily driven
by a decrease in actual hydro generation from expected as we!! as higher than forecast
market purchases, oftset by increased surplus sales.
16. Combined Uniform PCA Rate. The Company's uniform PCA rate for the
2022-2023 PCA Year is comprised of (1) the 1.'1926 cents per kilowatt-hour ('k\Jh")
APPLICATION - 6
adjustment for the 2022-2023 projected power cost of serving firm loads under the current
PCA methodology and g5 percent sharing and (2) 0.2579 cents per kWh for the 2021-
2022Balancing Adjustment. The sum of these two components results in an approximate
1.4505 cents per kWh charge for all rate classes.
III. REVENUE SHARING
17. The Company's earnings in each year from 2011 through 2015, as well as
2018, resulted in revenue sharing with ldaho customers totaling $126.2 million, either as
a direct rate ofbet in the PCA or as an ofbet to amounts that would have othenrise been
collected in rates. The Company's earnings in 2016, 20'17,2019, and 2020 were below
the revenue sharing threshold. As described in greater detail in the direct testimony of
Ms. Brady, the Company's 2021 ldaho jurisdictional year-end ROE was 10.02 percent.
ln accordance with the terms of the modified revenue sharing mechanism approved by
Order No. 34071, the Company's ldaho jurisdictional year-end ROE was above the 10.0
percent ROE threshold for revenue sharing. Therefore, the 2022-2023 PCA will include
a revenue sharing component of $568,771.
IV. CUMULATIVE PROPOSED JUNE 1. 2022. RATE CHANGES
18. PCA. The 2022-2023 total PCA amount, as measured from the currently
approved base level NPSE, including the revenue sharing provision, is $216.9 million.
This represents an increase in total billed revenue of $103.4 million, an increase of 8.27
percent, for ldaho customers, effective June 2022 through May 2023.
19. Fixed Cost Adiustment ("FCA"). On March 15,2022. ldaho Power filed its
annual FCA in Case No. IPC-E-22-07. The Company's 2022 FCA filing proposes a $4.9
million decrease in current billed revenue, or a 0.81 percent decrease, for ldaho
APPLICATION. T
Residential and Small General Service customers, effective June 2022 through May
2023.
20. Jim Bridoer Power Plant ("Bridoef) Cost Recoverv Request. On June 3,
2021, ldaho Power filed an application to increase rates to accelerate the depreciation
schedule for all coal-related investments at Bridger and establish a balancing account to
track the incrementalcosts and benefits associated with ldaho Power's cessation of coal-
fired operations at the plant. On February 16, 2022, the Company filed an amended
request to reflect changes resulting from the expected conversion of Bridger Units 1 and
2 to natural gas in accordance with the results of the 2021 Integrated Resource Plan. lf
the amended request is approved as filed, the filing would result in an increase of total
billed revenue of $27.1 million, an increase of 2.17 percent, for ldaho customers,
beginning June 1 ,2022.
21. Combined Effect of the PCA. FCA. and Bridoer Filinos. lf the proposed
PCA, FCA, and Bridger rate changes are approved as filed, the combined impact is an
overall increase in current billed revenue of $125.6 million, or 10.05 percent, for June
2022through May 2023.
22. Aftachment 1 to this Application is Idaho Power's proposed IPUC No. 29,
Tariff No. 101, in both clean and legislative formats, which contains the tariff sheets
speciffing the proposed Schedule 55 rates for providing retail electric service to its
customers in the state of Idaho for June 1,2022, through May 31 ,2023.
23. Aftachment 2 to this Application contains a summary of revenue impact
showing the effect to each customer class of applying the Company's proposed PCA
APPLICATION - 8
rates that collect $103.4 million more, from June 2022through May 2023, than the PCA
rates currently in effect.
24. Rate Mitiqation. Due to the magnitude of the requested increase, ldaho
Power considered proposing rate mitigation measures as part of this filing. As detailed in
the testimony of Ms. Brady, it has not done so for several reasons. The Company
believes that customer interests are generally best served by matching cost recovery as
closely as possible with the period in which power supply costs are incurred. Additionally,
mitigating rate impacts by spreading recovery over multiple years creates the possibility
that the deferred collection will result in "rate pancaking" with potential future rate
increases, essentially deferring an increase in the current year to create an even larger
increase in the future. The Company also considered prior Commission orders
concerning use of rate mitigation measures in the PCA. !n orders from the 2008, 2009,
2013, and 2020 PCA cases in which rate mitigation was discussed, the Commission
declined to adopt any rate mitigation measures, primarily for the same concerns
surrounding rate pancaking, appropriate matching of costs and recovery, and the overal!
intent of the PCA mechanism. Order Nos. 30563, 30828, 32821, and 34682.
25. While the Company is not proposing any rate mitigation measures in this
filing, it is open to discussing these measures if the Commission determines they may be
appropriate. A two-year recovery period, for example, would reduce the rate impact from
the proposed $103.4 million, or 8.27 percent increase, to an approximate $50 mi!!ion, or
slightly more than 4 percent, annual increase in collection spread over two years.
APPLICATION.9
V. MODIFIED PROCEDURE
26. Idaho Power believes that a technical hearing is not necessary to consider
the issues presented herein and respectfully requests that this Application be processed
under Modified Procedure, i.e., by written submissions rather than by hearing. RP 201,
ef seg. lf, however, the Commission determines that a technical hearing is required, the
Company stands ready to present its testimony and support the Application in such
hearing.
VI. COMMUNICATIONS AND SERVICE OF PLEADINGS
27. ln conformance with RP 125, this Application will be brought to the attention
of ldaho Power's customers by means of a press release to media in the Company's
service area and a customer notice distributed in customers' bills, both of which
accompany this filing. To ensure that all customers are notified in a timely manner and
have sufficient time to submit comments, ldaho Power is sending a direct mail postcard
to a subset of customers that receive their bill toward the end of the processing time for
this case. As such, a bill insert and/or the direct mail postcard will be mailed no later than
May 20, 2022.
28. The Company has also prominently displayed its intent to file the PCA on
its website since March 15,2022. Upon filing of this Application, this web graphic will link
directly to the PCA press release and bill insert. Idaho Power will also keep its
Application, testimonies, and exhibits open for public inspection at its offices throughout
the state of ldaho. ldaho Power asserts that this notice procedure satisfies the Rules of
Procedure of this Commission; however, the Company will, in the alternative, bring the
APPLICATION - 1O
Application to the attention of its affected customers through any other means directed by
this Commission.
