3 recovery authorized by the Commission in the Company's most
4 recent general rate case and the l-evel- of fixed cost
5 recovery that the Company received based upon the actual
6 billed energy sales during the prevj-ous calendar year.
7 Q. What leve1 of incremental annual DSM energy
8 efficiency savings did Idaho Power achieve in 20L6?
9 A. On a system-wJ-de basis, Idaho Power achieved
10 710,792 megawatt-hours of incremental annual energy
11 effici-ency savj-ngs Ln 2016, which is a 4 percent j-ncrease
t2 from savings reported j-n 201-5.
13 O. Please describe the ECA mechanism.
74 A. For both the Residential and Smal-l- General-
15 Service classes, the FCA mechanism is the same. The
76 formula used to determine the FCA amount is:
71 FCA : (CUST X ECC) (ACTUAL X FCE)
18 Where:
1-9 ECA : Eixed Cost Adjustment;
20 CUST : Average Number of Customers, by class;
2L FCC : Fixed Cost per Customer rate, by class;
22 ACTUAL : Actual Bil-ted kilowatt-hours (*kwh")
23 Energy Sa1es, by class; and
24 FCE : Eixed Cost per Energy rate, by cl-ass.

O. Can the FCA deferral balance be either
posi-ti-ve or negative?
A. Yes. The ECA amount is the di-f ference between
the Company's l-evel of "authorized fixed cost recovery"
(CUST X FCC) and the level of "actual fixed cost recovery"
(ACTUAL X FCE), which can result in either a positive or
negative FCA deferral- balance. A positive FCA indicates

e., the use per customer has decreased. The
13 effect would be that the Company has under coll-ected its
74 authorized level of fixed costs. In a similar fashion, a
15 negative FCA indicates the Company's authorized fixed cost
LG recovery amount is less than the fixed costs determined to
1,7 have been recovered through the energy rate and results in
18 a refund to customers.

20 O. Did the rates for the ECC and ECE change in
27 20L6?
22 A. No. The ECC and FCE rates used to determine
23 the 2076 FCA deferra1 bal-ance did not change and are the
24 same rates used to determine the 20L5 FCA deferral balance.
25 The FCC and FCE rates were established in the Company's

1 most recent general rate case, Case No.IPC-E-11-08, and
Schedule 54, Fixedare found in the Company's tariff under
Cost Adjustment.
O. How is the authorj-zed leveI of fixed cost
recovery derived?
A. The authorized level of fixed cost recovery is
the product of the FCC and the average number of customers,
by class. The Company uses a prorated customer count based
on the number of active utility service agreements at the
end of each month. This approach applies the same
11 methodology that was used to determine customer counts in
L2 the Company' s most recent general rate case. The annua.l-
13 average customer count is derived by calculating the
L4 average of the 12 monthly prorated customer counts.
15 O. How j-s the actual level of fixed cost recovery
16 determined?
1,7 A. In compliance with Order No. 33295 issued in
18 Case No. IPC-E-14-I7, the actual- Ievel of fixed cost
19 recovery j-s the product of the FCE and the actua1 bil-l-ed
20 energy sales for the calendar year, measured in kwh.
2L O. Does the Company compute a monthly ECA
22 deferral bal-ance and report the estimated monthly ECA
23 deferral balance to the Commission?
24 A. Yes. Although the FCA is an annual mechanism
25 that is ultimately calculated and determined using customer

Company
1 counts and bi11ed energy sales data for the entire cal-endar
2 year, to maj-ntain compl-iance with Generally Accepted
3 Accounti-ng Principles (GAAP), a monthly FCA deferral
4 balance is estimated and recorded in the Company's
5 accounting records. At year-end, once the annual FCA
6 amount is determined, an adjustment is made to the sum of
7 the prevj-ous1y recorded 12 monthly estimates to align with
8 the annual ECA deferral- balance. The annual customer count
9 is the average of the 12 monthly customer counts and is not
10 available until year-end. An adjustment is needed
11 primarj-1y because the monthly customer counts used to
t2 determine the estimated monthly FCA balance will- not align
13 with the average annual customer count.

10 O. Please describe the calculation of the FCA
11 rates the Company i-s proposing to go into effect on June 1,
L2 2011.
13 A. The FCA rates the Company proposes to go into
14 effect on June L, 2077, were calculated by taking the ECA
15 deferral balances for each customer class described above
16 and dividing by the respective class energy sales forecast
71 for the June t, 2071, through May 37, 20L8, time frame

3 Q. What are the corresponding FCA rates for the
4 Residential and Small- General Service classes based on a
5 combined and equal ECA rate changer ds defined in the
6 approved mechanism?
7 A. To recover the authorized level of fixed
I costs, the FCA rate for the Residential class woul-d be
9 0.6728 cents per kWh and the corresponding rate for the
10 Small General Service class would be 0.8576 cents per kwh.
11 The calculation of these rates is found in Exhibit No. 5.
72 fn Order No. 32505, the Commj-ssion ordered that the ECA
13 deferral balance will continue to be recovered or refunded
74 equally between the Residential and Small General Service
15 customer classes. Order No. 32505 at 9. Because the
76 Residential and SmaII General Service classes reduced their
t7 energy consumption per customer such that the Company under
18 coll-ected its authorized level of fixed costs as
79 establlshed in Case No. IPC-E-I1-08, each class requires a
20 rate surcharge.
2! O. What is the difference between the ECA
22 deferral balance currentl-y in amortlzatj-on and the proposed

$35,0L2,042, which is $6,951,500 more than the current FCA
deferral balance of $28,054,542. The current deferral
balance was approved in Order No. 33527, issued in Case No.
IPC-E-1 6-02, with rates based on that balance effective for
the period June L, 20L6, through May 31, 2077. Order No.
33527 at 4.
O. How is the 3 percent rate adjustment cap
determined?
10 by the
A. As agreed to in the stipulation and approved
Commission 1n Order No. 33295, the Company
11 calculates the 3 percent cap on annual increases
1,4 0. Does the proposed FCA deferraf balance exceed
15 the 3 percent cap on annual increases over base revenue?
76 A. No, the proposed ECA deferral balance does not
I7 exceed the 3 percent cap on annual increases over base
18 revenue. The proposed FCA deferral balance is an increase
79 of $6,957,500 over the existing FCA deferral balance. The
20 total base revenue for the Company's Test Year for the
