Please state your educational background and professional experience.

In 1998, I graduated from San Antonio Abad University in Peru with a Bachelor of Science

in Mechanical Engineering. In 2005, as a Fulbright Scholar, I graduated with a Masters in

Business Administration, with a concentration in Finance, from Willamette University in

Salem, Oregon. My professional experience includes more than 20 years working within

the energy industry, energy regulation, and academia. From 1999 to 2008, I worked for a

power generation company in Peru in various roles such as Shift Operations Engineer,

Manager of Economic Planning, and Vice-President of Power Operations and Marketing.

From 2009 to 2016, I worked as a Senior Financial Economist for the Public Utility

Commission of Oregon. From 2017 to 2018, I taught Accounting for Decision Makers and


000004

the Commission.

8 II. PURPOSE AND SCOPE OF TESTIMONY

9 Q. What issues identified in the Preliminary Order does your testimony address?

10 A. My testimony addresses the following issue identified in the Commission' s Preliminary

11 Order filed May 7, 2021 in this proceeding:

12 57. Should baseline amounts be determined in this proceeding for future SPS

13 interim transmission cost of service, transmission-cost-recovery-factor, or

14 distribution-cost-recovery-factor filings? If so, what are the investment and

15 expense components and amounts?

16 Q.

17

18

19 A.

20

If you do not address an issue or position in your testimony, should that be

interpreted as Staff supporting Southwestern Public Service Company's (SPS)

position on that issue?

No. The fact that I do not address an issue or position in my testimony should not be

construed as agreeing with, endorsing, or consenting to any position taken by SPS.

21 Q.

22 A.

23

What is your role in this proceeding?

I prepared Commission Staff' s Class Cost of Service Study (CCOSS), which incorporates

Staff's proposed jurisdictional allocation, functionalization, and class allocation


000005


1 treatments. A summary of the CCOSS can be found in Attachment JO-2. In preparing

2 Staff's CCOSS, I incorporate the recommended adjustments presented by Staff witnesses

3 William Abbott and Mark Filarowicz. I then calculate Staff's recommended SPS Texas

4 retail rates and Staff' s recommended distribution cost recovery factor (DCRF), purchased

5 power capacity cost recovery factor (PCRF), and transmission cost recovery factor (TCRF)

6 baseline values based on Staff's CCOSS.

7 Q.

8

9 A.

10

11

12

13

What documents and data did you review in arriving at the conclusions and

recommendations contained in your testimony?

In order to arrive at the recommendations proposed in my testimony, I reviewed the

Application of Southwestern Public Service Company for Authority to Change Rates

(Application), including witness testimony, and SPS's responses to various Requests for

Information (RFIs) during the discovery period. I also considered previous base rate cases

filed by SPS before the Commission.

14

15 III. SUMMARY OF RECOMMENDATIONS

16 Q. What is your recommendation?

17 A. I recommend that:

18 • The Commission approve Staff's proposed DCRF, TCRF, and PCRF baselines

19 included as Attachment JO-9; and

20 • The Commission approve Staff's proposed rates as identified in Attachment JO-7.

21 Q.

22 A.

23

What Texas retail revenue requirement results from Staff's recommendations?

Incorporating all of Staff' s adjustments produces a Texas retail revenue requirement for

SPS of $729,216,738. This represents a $110,359,939 increase from SPS's Texas retail


000006


1 present revenues of $618,856,799.1 The summary of these figures can be found in

2 Attachment JO-2. This compares to SPS's proposed Texas retail revenue requirement of

3 $761,917,417, which represents a $143,060,618 increase from SPS's proposed Texas retail

4 present revenues.2

5

6 IV. BASELINES

7 Q. What are baseline values?

8 A. Baseline values represent a detailed snapshot of certain base-rate related parameters for

9 SPS's DCRF, TCRF, and PCRF rate formulas to be used in SPS's potential future DCRF,

lo TCRF, or PCRF proceedings. A utility may initiate the aforementioned proceedings

11 between base rate cases to seek approval to recover certain incremental costs that are not

12 being recovered in base rates. Establishing baseline values in the present rate case

13 facilitates the process of determining these incremental costs in future cost recovery factor

14 proceedings.

15 Q.

16

17 A.

18

19

20

Did you make any adjustments to SPS's calculation of DCRF, TCRF, and PCRF

baselines?

Yes. The Staff-recommened baseline values are different from the SPS-proposed baselines

as a result of the flow-through effects resulting from recommended adjustments presented

by Staff witnesses William Abbott and Mark Filarowicz. Beyond these flow-through

effects, I made no adjustments to the baselines proposed by SPS.
