Docket No. UE 301 Staff/100 Gibbens/1

Q. Please state your name, occupation, and business address. 1

A. My name is Scott Gibbens. I am a Utility Analyst for the Public Utility 2

Commission of Oregon. My business address is 201 High St. SE Ste. 100 3

Salem, Oregon 97301. 4

Q. Please describe your educational background and work experience. 5

A. My Witness Qualification Statement is found in Exhibit Staff/101. 6

Q. What is the purpose of your testimony? 7

A. The purpose of my testimony is to present Staff’s analysis and concerns 8

regarding the 2016 October Update, the first portion of Idaho Power 9

Company’s (IPC or Company) Annual Power Cost Update (APCU). 10

Q. How is your testimony organized? 11

A. My testimony is organized as follows: 12

Filing, Compliance and Model Changes .................................................... 1 13 Issues ......................................................................................................... 4 14

Filing, Compliance and Model Changes 15 Q. Did the filing conform to applicable rules and orders? 16

A. Yes, the filing follows all of the applicable rules and orders. Commission Order 17

No. 08-238 (Order) contains the majority of rules and stipulations regarding the 18

APCU October Update. The Order requires IPC to utilize the AURORA model 19

to determine the estimated net power supply expense and reprice the 20

wholesale electric prices. In addition, the Order stipulates inputs to be updated 21

annually, which will be discussed in the following section. 22

Docket No. UE 301 Staff/100 Gibbens/2

Q. Please describe what inputs the Company updated. 1

A. Per the Order, the Company updated the following inputs: 2

a. Fueling prices and transportation costs; 3

b. Planned outages and forced outage rates; 4

c. Heat rates; 5

d. Forecast of Normalized Load and Normalized Sales; 6

e. Contracts for wholesale power and power purchases and sales; 7

f. Forward price curve; 8

g. PURPA contract expenses; and 9

h. The Oregon state allocation factor. 10

IPC did not update wheeling expenses from the previous filing as there was no 11

update submitted by the Company’s transmission planning group due to the 12

fact that wheeling expenses had not changed since the previous filing. 13

Q. Did Staff check the validity and reasonableness of the updated input 14

parameters? 15

A. Yes, Staff reviewed every updated input used in the October Update. In 16

general, the values seem reasonable and in line with both previous filings and 17

last year’s actual parameter values. Staff currently has pending several Data 18

Requests that are intended to clarify a few outliers. Potential issues associated 19

with input parameters are discussed later in my testimony. 20

Q. Did IPC perform the prescribed calculations properly? 21

Docket No. UE 301 Staff/100 Gibbens/3

A. Yes, Staff has found no errors associated with the calculations used in the 1

APCU. Company adhered to all pertinent Commission orders in every 2

calculation. 3

4

Q. How does this projection compare with last year’s actual parameter 5

values? 6

A. Historically, the 2015 calendar year was a poor hydro year. The hydro power 7

generated was approximately 30 percent lower than the mean of the previous 8

87 years. This resulted in higher generation costs among coal, natural gas and 9

purchased power. The total “net power supply expense” NPSE for the calendar 10

year was $388,073,000. The October Update predicts an April-March NPSE of 11

$352,028,000. Staff believes that the ten percent discrepancy between these 12

two numbers is warranted given the nature of the hydro year. 13

Q. Did the Company propose any modeling changes in the APCU? 14

A. Yes, there was one major change to the model. The Company adjusted the 15

manner in which it portrays operations and maintenance (O&M) costs. These 16

costs are associated with oil, handling, administrative and general expenses 17

(OHAG) and do not vary with the amount of power generated by the plant. As 18

such, IPC removed these costs from the AURORA model and added them 19

back as a fixed cost after the model was run. This resulted in a change to the 20

“per unit” costs of coal fired plants, notably Valmy. The results of last year’s 21

and this year’s APCU modeling remain similar. Staff finds that NPSE are 22

Docket No. UE 301 Staff/100 Gibbens/4

projected to rise approximately 3.5 percent. This year’s update estimated a 1

decrease in coal-generated power of approximately 35 percent. 2

3

Q. What impact on NPSE does the model change to O&M have, according 4

to the Company? 5

A. Including O&M expenses outside of the AURORA model will more closely align 6

the projection with the actual decisions made by IPC’s dispatching department. 7

The change will ensure that these costs are recovered regardless of the 8

amount of generation by a plant. 9

Issues 10

Q. What issues does Staff have in regards to the change to modeling O&M 11

costs in AURORA? 12

A. In principal, Staff agrees that fixed costs modeled as variable costs will result in 13

misallocations and inefficiencies. However, Staff still has concerns with the 14

stated reasons and results of the model change. 15

Q. Do you agree that the main driver of the increase in per–unit cost at 16

Valmy is the change in OHAG expense modeling? 17

A. No, Idaho Power/100, Noe/8 at lines 9 through 11 states that the “change in 18

modeling and recovery of OHAG expenses (is) the main driver of the increase 19

in per-unit cost at Valmy.” This is not correct. The increase in per unit costs is 20

due to a decrease in annual energy from 2015 to 2016. However, had OHAG 21

remained as a variable cost in the modeling, annual energy would have 22

decreased even more (See Table 1 below.) Staff is continuing to investigate 1

the appropriate modeling treatment of OHAG. 2

Q. Does Staff have further questions regarding O&M costs? 4

A. Yes. Staff found that the Boardman plant O&M was over 9,000 times smaller 5

than either of IPC’s other two coal plants. In response to Staff’s stated issues, 6

IPC responded that this was due to IPC having minority ownership in the plant, 7

and thus contributing less to O&M costs. However, Staff does not believe that 8

the relative difference in ownership among plants is sufficient to explain the 9

discrepancy between O&M at the Boardman plant as compared to IPC’s two 10

other plants. Staff continues to investigate this discrepancy. 11

Q. What issue does Staff have with regard to contract costs? 12

A. Staff requested information regarding the projected PURPA contract costs for 13

calendar years 2015 and 2016. Staff has further questions following IPC’s 14

confidential response to its data request. 15

Q. Is Staff investigating any other issues? 16

A. Yes. Staff believes FERC account 501, related to recovery under the power 17

cost adjustment mechanism, includes some component of labor costs. Staff is 18 1 Exhibit Staff/102 2 Exhibit Staff/103 3 Exhibit Idaho Power/101

investigating whether these costs are appropriately included in the power cost 1

calculations. These accounts also include certain fixed costs related to 2

depreciation. Staff is investigating whether these costs are appropriately 3

included in the power cost calculations. 4

Q. Does this conclude your testimony? 5

A. Yes. 6
