IDAHO PUBLIC
UTILITIES COMMISSION
GORALSKI, DI 2
Idaho Power Company
Q. Please state your name and business address. 1
A. My name is Pawel (“Paul”) P. Goralski. My 2
business address is 1221 West Idaho Street, Boise, Idaho 3
83702. 4
Q. By whom are you employed and in what capacity? 5
A. I am employed by Idaho Power Company (“Idaho 6
Power” or “Company”) as a Regulatory Consultant in the 7
Regulatory Affairs Department. 8
Q. Please describe your educational background. 9
A. In May of 2007, I received a Bachelor of 10
Business Administration degree in Finance from Boise State 11
University in Boise, Idaho. I have also attended “The 12
Basics: Practical Regulatory Training for the Electric 13
Industry,” an electric utility ratemaking course offered 14
through the New Mexico State University’s Center for Public 15
Utilities, “Electric Utility Fundamentals and Insights,” an 16
electric utility course offered by Western Energy 17
Institute, and “Electric Rates Advanced Course,” an 18
electric utility ratemaking course offered through Edison 19
Electric Institute. 20
Q. Please describe your work experience with 21
Idaho Power. 22
A. In 2017, I was hired as a Regulatory Analyst 23
in the Company’s Regulatory Affairs Department, and in 2020 24
I was promoted to my current position of Regulatory 25
GORALSKI, DI 3
Idaho Power Company
Consultant. My primary responsibilities include supporting 1
the Company’s class cost-of-service activities, developing 2
pricing for special contract customers and other large load 3
pricing analysis, supporting the Company’s annual Fixed 4
Cost Adjustment (“FCA”) calculation and serving as the 5
Company witness. I have also been its witness for the 6
Company’s annual Demand-Side Management (“DSM”) prudency 7
filings. 8
Q. What is the purpose of your testimony? 9
A. The purpose of my testimony is to describe the 10
Company’s request to implement its annual FCA rates in 11
conformance with Idaho Public Utilities Commission 12
(“Commission”) Order No. 32505 (Case No. IPC-E-11-19), 13
which approved the FCA as a permanent rate mechanism for 14
the Residential and Small General Service customers, and 15
Order No. 35273 (Case No. IPC-E-21-39), which approved 16
modification of the FCA to institute separate fixed cost 17
tracking for residential and small general service 18
customers added to the Company’s system effective January 19
1, 2022. 20
Q. What is the Company requesting in this case? 21
A. The Company is seeking authority to collect 22
the 2022 FCA deferral balance of $25,065,075 through its 23
proposed 2023-2024 FCA rates. If approved, the 2023 – 2024 24
FCA rates will result in a decrease to annual billed 25
GORALSKI, DI 4
Idaho Power Company
revenue for the Residential and Small General Service 1
classes of $9,976,903, or 1.56 percent, effective June 1, 2
2023. 3
Q. How is your testimony organized? 4
A. My testimony will discuss four areas related 5
to the FCA mechanism and Schedule 54, Fixed Cost 6
Adjustment. First, I will discuss the need for the FCA 7
itself. Second, I will discuss how the FCA modification 8
approved by Order No. 35273 was incorporated in the 2022 9
FCA deferral balance. Third I will provide an overview of 10
the FCA mechanics and how each component is determined, and 11
determination of the 2022 FCA deferral amount. Lastly, I 12
will discuss the calculation of the proposed FCA rates to 13
become effective June 1, 2023, remaining in effect until 14
May 31, 2024. 15
I. BENEFIT OF FIXED COST ADJUSTMENT MECHANISM 16
Q. Why is the FCA mechanism necessary? 17
A. The existing two-part rate design for 18
Residential and Small General Service customers collects a 19
significant portion of the classes’ fixed costs through the 20
volumetric energy rate. The FCA is a true-up mechanism that 21
“decouples,” or separates, billed energy sales from revenue 22
in order to remove the financial disincentive that exists 23
when the Company invests in DSM resources and activities. 24
Under the FCA, rates for Residential Service (Schedules 1, 25
GORALSKI, DI 5
Idaho Power Company
3, 4, 5, and 6) and Small General Service (Schedule 7 and 1
8) customers are adjusted annually to recover or refund the 2
difference between the level of fixed cost recovery 3
authorized by the Commission in the Company’s most recent 4
general rate case and the level of fixed cost recovery that 5
the Company received based upon the actual billed energy 6
sales during the previous calendar year. 7
Q. What level of incremental annual energy 8
efficiency savings was achieved in 2022? 9
A. Idaho Power achieved 169,889 megawatt-hours 10
(“MWh”) of savings system-wide, which is enough energy to 11
power approximately 14,900 average homes a year in Idaho 12
Power’s service area and exceeded the economic technical 13
achievable potential energy efficiency target set in the 14
Company’s 2021 Integrated Resource Plan for the year 2022. 15
These energy savings are more particularly described in the 16
2022 DSM Annual Report filed in Case No. IPC-E-23-10. 17
Q. Do claimed incremental DSM savings encompass 18
the entirety of energy savings customers experience from 19
Idaho Power’s DSM efforts? 20
A. No. First, it is important to recognize that 21
savings claimed in any given year continue to recur in 22
subsequent years through the life of the DSM measure. For 23
example, a measure installed in 2019 with a five-year 24
measure life continues to provide energy savings in 2022, 25
GORALSKI, DI 6
Idaho Power Company
though those savings are not included in the 2022 claimed 1
savings reported in the Company’s 2022 DSM Annual Report. 2
Thus, the full impact of the Company’s DSM efforts is 3
better represented by the cumulative impact of historical 4
claimed savings whose measure life extends through 2022. 5
Second, the Company promotes significant customer 6
educational, outreach and awareness activities, promotion 7
of codes and standards, and marketing efforts that are not 8
quantified or claimed as part of Idaho Power’s annual DSM 9
savings but are likely to result in energy savings 10
experienced by the customer and accruing to Idaho Power’s 11
electric system over time. 12
Q. Has the FCA mechanism been effective at 13
removing the financial disincentive that would otherwise be 14
associated with Idaho Power pursuing all cost-effective 15
energy efficiency? 16
A. Yes. The FCA has been and continues to be an 17
effective mechanism that has positioned the Company to 18
continue to support energy efficiency resources while 19
maintaining a reasonable opportunity to recover its fixed 20
cost of serving residential and small commercial customers. 21

II. 2022 FCA DEFERRAL INCLUSIVE OF COMMISSION-APPROVED 1
MODIFICATION 2
Q. Does determination of the 2022 FCA deferral 3
amount include the modification approved by the Commission 4
in Case No. IPC-E-21-39? 5
A. Yes. As part of determining the 2022 FCA 6
deferral, customers added to Idaho Power’s system starting 7
January 1, 2022, are considered “new” and have separate, 8
reduced fixed cost tracking, while the 2021 FCA customer 9
count constitutes the level of “existing” customers whose 10
fixed costs are tracked with then-existing FCA components. 11
These new and existing FCA components are described in more 12
detail later in my testimony. 13
Q. How was the existing customer count determined 14
in the calculation of the 2022 FCA deferral? 15
A. Consistent with the method approved by the 16
Commission in Order No. 35273, the existing customer count 17
was set at the 2021 average number of customers. This 18
existing customer count will remain at that level until new 19
rates go into effect following the Company’s next general 20
rate case. 21
Q. How was the new customer count determined in 22
the calculation of the 2022 FCA deferral? 23
A. Because the FCA is an annual mechanism based 24
on average customers for the entire year, new customers 25
GORALSKI, DI 8
Idaho Power Company
were determined as the difference between 2021 average 1
customers and 2022 average customers. This method captures 2
customers added starting January 1, 2022 through December 3
31, 2022 to determine the annual average incremental or 4
“new” customer count. 5
Q. Is there a difference in FCA rates to recover 6
the FCA deferral between existing and new customers? 7
A. No. While determination of the 2022 FCA 8
deferral includes separate, and reduced fixed cost tracking 9
for new customers, the 2022 FCA deferral is recovered 10
through a single FCA rate applicable to all Residential 11
customers, new and existing, and a single FCA rate 12
applicable to all Small General Service customers. 13
III. FCA DETERMINATION FOR CALENDAR YEAR 2022 14
Q. Please describe the FCA mechanism components 15
and calculation. 16
A. For both the Residential and Small General 17
Service classes, the FCA mechanism is the same. The formula 18
used to determine the FCA amount is: 19
FCA = (CUST X FCC) – (ACTUAL X FCE) 20
Where: 21
FCA = Fixed Cost Adjustment; 22
CUST = Average Number of Customers, by class; 23
FCC = Fixed Cost per Customer rate, by class; 24
GORALSKI, DI 9
Idaho Power Company
ACTUAL = Actual Billed kilowatt-hours (“kWh”) 1
Energy Sales, by class; and 2
FCE = Fixed Cost per Energy rate, by class. 3
The FCA amount is the difference between the Company’s 4
level of “authorized fixed cost recovery” (CUST X FCC) and 5
the level of “actual fixed cost recovery” (ACTUAL X FCE). 6
The FCC and FCE are bifurcated for new and existing 7
customers, with new customer components labeled as “FCC-8
Dist” and “FCE-Dist.” 9
Q. What is the difference in fixed cost tracking 10
between new and existing customers, and what is the basis 11
for those costs? 12
A. For both new and existing customers, the basis 13
for fixed cost tracking is the same, the Company’s most 14
recent general rate case. Existing customer FCC and FCE 15
remain unchanged and represent fixed costs associated with 16
the Company’s generation-, transmission-, and distribution-17
related system components. Starting with the 2022 deferral, 18
for new customers only the distribution-related system cost 19
components are tracked by the FCA. Table 1 lists the FCA 20
cost components for new and existing customers. 21
// 22
// 23
// 24
// 25
GORALSKI, DI 10
Idaho Power Company
Table 1. FCA Components – Existing and New Customers 1
Residential Small General Service
FCC (per Existing Customer) $650.63 $360.57
FCC-Dist. (per New Customer) $317.72 $256.29
FCE (per kWh Existing Customer) $0.051602 $0.068633
FCE-Dist. (per kWh New Customer) $0.025199 $0.048783
2
Q. Can the FCA deferral balance be either 3
positive or negative? 4
A. Yes. A positive FCA indicates the Company's 5
authorized level of fixed cost recovery is greater than the 6
level of fixed costs recovered through the energy rate, 7
which occurs when energy use per customer (“UPC”) has 8
decreased from when the FCA components were established. In 9
a similar fashion, a negative FCA indicates the Company's 10
authorized fixed cost recovery amount is less than the 11
fixed costs determined to have been recovered through the 12
energy rate and results in a refund to customers. 13
Q. Did the underlying cost basis for the FCC and 14
FCE rates used to determine the 2022 FCA deferral balance 15
change from prior years? 16
A. No. All customers included in the 2022 FCA 17
calculation use costs from the Company’s most recent 18
general rate case, Case No. IPC-E-11-08, to establish the 19
FCC and FCE, and they can be found in the Company’s tariff 20
under Schedule 54, Fixed Cost Adjustment. FCC-Dist and FCE-21
Dist rates are based on the same underling general rate 22
GORALSKI, DI 11
Idaho Power Company
case data, but only represent distribution system costs as 1
previously noted, and were established as part of the FCA 2
modification filing, IPC-E-21-39. 3
Q. How is the authorized level of fixed cost 4
recovery derived? 5
A. The authorized level of fixed cost recovery is 6
the product of the applicable FCC and the average number of 7
customers, by new and existing customer, and by class. The 8
Company uses a prorated customer count based on the number 9
of active utility service agreements at the end of each 10
month. This approach applies the same methodology that was 11
used to determine customer counts in the Company’s most 12
recent general rate case. The annual average customer count 13
is derived by calculating the average of the 12 monthly 14
prorated customer counts. 15
Q. How is the actual level of fixed cost recovery 16
determined? 17
A. In compliance with Order No. 33295, the actual 18
level of fixed cost recovery is the product of the 19
applicable FCE and the actual billed energy sales for the 20
calendar year, measured in kWh. 21
Q. How are billed energy sales allocated between 22
existing and new customers? 23
A. For each customer group, Residential and Small 24
General Service, total billed energy sales are divided by 25
GORALSKI, DI 12
Idaho Power Company
average customer count to determine the UPC for the 1
customer group. The count of existing and new customers is 2
multiplied by the respective customer group UPC to allocate 3
the share of total billed energy sales on a pro rata basis 4
between existing and new customers. 5
Q. Does the Company compute a monthly FCA 6
deferral balance? 7
A. Yes. Since 2009, the Company has reported the 8
estimated monthly FCA deferral balance in the monthly FCA 9
Report provided to the Commission. Exhibit No. 1 is a copy 10
of the monthly FCA Report for calendar year 2022 with year-11
end information. 12
Although the FCA is an annual mechanism that is 13
ultimately calculated and determined using customer counts 14
and billed energy sales data for the entire calendar year, 15
a monthly FCA deferral balance is estimated and recorded in 16
the Company’s accounting records to maintain compliance 17
with Generally Accepted Accounting Principles. This 18
estimated monthly FCA deferral balance is provided to the 19
Commission in the monthly FCA Report. 20
Q. Is it possible for the reported monthly FCA 21
deferral balance estimate to differ from the annual amount? 22
A. Yes. Because the monthly FCA deferral balance 23
is computed using monthly customer counts while the annual 24
FCA deferral balance is computed using the average customer 25
GORALSKI, DI 13
Idaho Power Company
count for the year, the sum of the monthly calculations may 1
differ from the annual calculation. 2
Q. How is the reported monthly estimate adjusted 3
to align with the authorized annual amount? 4
A. At year-end, once the annual FCA amount is 5
determined, an adjustment is made to the sum of the 6
previously recorded 12 monthly estimates to align with the 7
annual FCA deferral balance. Because the annual customer 8
count is the average of the 12 monthly customer counts, it 9
is not available until year-end. 10
Q. What adjustment was made to the 2022 monthly 11
estimates to translate to the Company’s single year-end 12
2022 FCA deferral balance? 13
A. To align with the annual FCA amount to be 14
recorded in the Company’s 2022 financial records, an upward 15
adjustment of $134,280 was made for the Residential 16
customer classes, reflected as the sum of lines 6 and 11, 17
column O of Exhibit No. 1. A downward adjustment of $249 18
was made for the Small General Service customer classes, 19
reflected as the sum of lines 25 and 30, column O of 20
Exhibit No. 1. The total upward adjustment for both 21
customer classes is $134,031. 22
Q. What is the total amount of the FCA, not 23
including interest? 24
GORALSKI, DI 14
Idaho Power Company
A. As shown in Exhibit No. 2, the total amount of 1
the FCA for the Residential and Small General Service 2
customer classes, not including interest, is $24,715,199. 3
The calculation of the FCA uses the average annual customer 4
count and the annual billed sales amount, which are 5
included in Exhibit No. 3. The calculated FCA deferral 6
balance for the Residential customer classes, not including 7
interest, is $23,740,357. An amount of $23,740,356 is found 8
in Exhibit No. 1 when summing lines 6 and 11, column P. 9
The $1 difference between Exhibit No. 1 and Exhibit No. 2 10
is due to rounding. 11
The calculated FCA deferral balance for the Small 12
General Service customer classes, not including interest, 13
is $974,842. An amount of $974,841 is found in Exhibit No. 14
1 when summing lines 25 and 30, column P, with the 15
difference between Exhibit No. 1 and Exhibit No. 2 also due 16
to rounding. 17
Q. What is the total amount of the 2022 FCA, 18
including interest, the Company is requesting to implement 19
in rates on June 1, 2023? 20
A. The total amount of the 2022 FCA the Company 21
is requesting to begin recovering in rates on June 1, 2023, 22
is $25,065,075.31, reflected on line 42, column V, of 23
Exhibit No. 4. The FCA for the Residential classes is 24
$24,076,901.44 reflected on line 20, column V, of Exhibit 25
GORALSKI, DI 15
Idaho Power Company
No. 4. The FCA for the Small General Service classes is 1
$988,173.87 reflected on line 39, column V, of Exhibit No. 2
4. Exhibit No. 4 and Exhibit No. 1 both contain the same 3
information as the FCA Report sent to the Commission each 4
month; however, Exhibit No. 4 calculates interest from 5
January 2022 through May 2023 while Exhibit No. 1 shows 6
that information only for the 2022 calendar year. 7
Q. What is the significance of these numbers with 8
respect to the Company’s recovery of its fixed costs? 9
A. Because the Residential and Small General 10
Service FCAs are positive numbers, the average UPC based on 11
actual billed sales for the year were lower than the level 12
established in the Company’s most recent general rate case 13
for both Residential and Small General Service customer 14
classes. In accordance with the approved mechanism, the 15
Residential and Small General Service classes will receive 16
a rate adjustment to allow for recovery of the fixed costs 17
that were not recovered through actual billed energy 18
charges during the year. 19
IV. CALCULATION OF THE 2023-2024 FCA RATE 20
Q. Please describe the calculation of the FCA 21
rates the Company is proposing to go into effect on June 1, 22
2023. 23
A. The FCA rates the Company proposes to go into 24
effect on June 1, 2023, were calculated by taking the FCA 25
GORALSKI, DI 16
Idaho Power Company
deferral balances for each of the customer classes 1
described above and dividing by the respective class energy 2
sales forecast for the June 1, 2023, through May 31, 2024, 3
time frame. The forecasted June 1 through May 31 time frame 4
is the same period that has been used historically and is 5
also used for the Power Cost Adjustment mechanism. 6
Q. What has the Company determined the forecast 7
energy sales to be for both the Residential and Small 8
General Service classes? 9
A. The Company’s forecasted energy sales are 10
5,519,189,071 kWh for the Residential classes and 11
139,209,221 kWh for the Small General Service classes. The 12
forecasted energy sales are found in Exhibit No. 5. 13
Q. What are the corresponding FCA rates for the 14
Residential and Small General Service classes based on a 15
combined and equal FCA rate change, as defined in the 16
approved mechanism? 17
A. To recover the authorized level of fixed 18
costs, the FCA rate for the Residential classes would be 19
0.4402 cents per kWh and the corresponding rate for the 20
Small General Service classes would be 0.5541 cents per 21
kWh. The calculation of these rates is also found in 22
Exhibit No. 5. 23
On page 9 of Order No. 32505, the Commission ordered 24
that the FCA deferral balance will continue to be recovered 25
GORALSKI, DI 17
Idaho Power Company
or refunded equally between the Residential and Small 1
General Service customer classes. Because the Residential 2
and Small General Service classes reduced their energy 3
consumption per customer such that the Company under-4
collected its authorized level of fixed costs as 5
established in Case No. IPC-E-11-08, each class requires a 6
rate surcharge. 7
Q. What is the difference between the FCA 8
deferral balance currently in amortization and the proposed 9
FCA deferral balance to be collected through the FCA rate? 10
A. In this filing, the Company is proposing to 11
collect rates based on an FCA deferral balance of 12
$25,065,075.31 which is $10,138,173 less than the 2021 FCA 13
deferral balance of $35,203,248. The 2021 deferral balance 14
was approved in Order No. 35410, issued in Case No. IPC-E-15
22-07, with rates based on that balance effective for the 16
period June 1, 2022, through May 31, 2023. 17
Q. Considering the current FCA rates in effect, 18
what is the percentage change in billed revenue as measured 19
from total billed amounts currently recovered from 20
Residential and Small General Service classes? 21
A. Because the 2022 FCA deferral balance is less 22
than the 2021 FCA deferral balance and annual sales for 23
June 2023 through May 31, 2024 are forecast to be slightly 24
lower than the same period in the prior year, the 2023 – 25
GORALSKI, DI 18
Idaho Power Company
2024 FCA rates represent an annual decrease of $9,976,903, 1
or 1.56 percent, from current billed revenue for the 2
affected customer classes. The percentage change in billed 3
revenue is found in Exhibit No. 6. This proposed decrease 4
results in an approximate $1.66 decrease to the monthly 5
bill of a typical residential customer using 950 kWh per 6
month. 7
Q. How will the Company incorporate the FCA 8
surcharges for the Residential and Small General Service 9
classes on customers’ bills? 10
A. The Company proposes to continue including the 11
FCA with the Fixed Cost Adjustment line item on Residential 12
and Small General Service customers’ bills. 13
V. CONCLUSION 14
Q. Please summarize the Company’s request in this 15
filing. 16
A. Idaho Power requests the Commission authorize 17
the Company to implement Fixed Cost Adjustment rates for 18
electric service from June 1, 2023, through May 31, 2024 in 19
the amount of 0.4402 cents per kWh for the Residential 20
classes, and 0.5541 cents per kWh for the Small General 21
Service classes. If approved, the 2023 – 2024 FCA rates 22
will result in a decrease to annual billed revenue for the 23
Residential and Small General Service classes of 24
$9,976,903, or 1.56 percent, effective June 1, 2023. 25
