BEFORE THE PUBLIC UTILITIES COMMISSION OF NEVADA Sierra Pacific Power Company d/b/a NV Energy
2016 General Rate Case Gas Department
Docket No. 16-06007
Prepared Certification Testimony of
Laura I. Walsh
Rate Design
I. INTRODUCTION
1. Q. PLEASE STATE YOUR NAME, OCCUPATION, BUSINESS ADDRESS
AND PARTY FOR WHOM YOU ARE FILING TESTIMONY.
A. My name is Laura I. Walsh. I am the Director of Regulatory Analysis, Policy and
Strategy for Sierra Pacific Power Company, d/b/a NV Energy (“Sierra” or the
“Company”) and Nevada Power Company, d/b/a NV Energy (“Nevada Power” and
together with Sierra, the “Companies”). My business address is 6100 Neil Road,
Reno, Nevada. I am filing testimony on behalf of Sierra.
2. Q. HAVE YOU PREVIOUSLY OFFERED PREPARED DIRECT
TESTIMONY IN THIS CASE?
A. Yes, I have.
3. Q. WHAT IS THE PURPOSE OF YOUR TESTIMONY IN THE
CERTIFICATION UPDATE TO THIS CASE?
A. I am Sierra’s witness addressing policy matters related to the Company’s proposed
gas cost of service and rate design. My prepared certification testimony provides
updates to my prepared direct testimony regarding proposed Basic Service Charges

(“BSC”) which include the results of an updated Gas Rule 9 Facilities Study
(“Study”). The original Study has been modified to incorporate corrections to two
errors that were identified subsequent to the direct filing. Cary Shelton-Patchell
supports the development and technical aspects of the Company’s certification cost
of service study and Statement O rate design as well as the updates to the Rule 9
facilities costs.
II. POLICY GUIDING RATE DESIGN FOR THIS GAS GRC
4. Q. HAVE THE POLICY CONSIDERATIONS GUIDING THE GAS RATE
DESIGN CHANGED FROM THOSE STATED IN YOUR PREPARED
DIRECT TESTIMONY?
A. No. The Commission’s past recognition of the importance of moving toward cost-
based levels in each of the past three gas general rate review proceedings continues
to be reflected in the Company’s certification proposal. The Company proposes gas
prices that eliminate both inter-class and reduce intra-class subsidies by setting
class revenue requirements at cost, as well as Basic Service Charges (“BSCs”) that
recover all costs that are generally fixed in nature. The necessary exceptions
continue to be incentive natural gas rate (“INGR”) and gas transportation
(“Transportation”) rates.

III. BASIC SERVICE CHARGES
5. Q. PLEASE EXPLAIN WHY SIERRA’S PROPOSED INCREASES IN BASIC
SERVICE CHARGES SHOULD BE APPROVED.
A. Sierra is proposing increases in the BSC for the Residential and Small Commercial
customer classes. The proposed increases are consistent with a compliance item in
the Commission’s Order in Docket No. 13-06003 in that the BSC recovers Rule 9
facilities costs1 and reflects the importance of reducing intra-class subsidies. The
BSC reflect the certification cost of service results and are summarized below:
BSC Proposal
Present Proposed % of Customer & Facilities Residential 14.00 $ 17.00 $ 100% Small Commercial 18.00 $ 37.00 $ 89% Large Commercial $1,000.00 $1,000.00 93% Incentive $2,300.00 $2,300.00 100% Transportation $ 1,000.00 $ 1,000.00 170%
Large Commercial, INGR, and Transportation BSCs remain unchanged from
present. Additionally, the Transportation per-customer, per-month, administrative
charge, remains unchanged at $300.00. If approved, the certification proposal for
BSCs for all classes will essentially recover all customer and Rule 9 facilities costs.
The exception remains with the Small Commercial class. The Company proposes
to move the BSC for this class halfway from present rates toward a cost-based rate
to mitigate the effect of the change while making significant progress in eliminating
the intra-class subsidy. The proposed Small Commercial BSC at certification will
recover 89% of the customer and Rule 9 facilities costs.
1 Commission Modified Final Order in Docket Nos. 13-06002, 13-06003, and 13-06004, Directive 12, at p. 201.

As stated in my prepared direct testimony, cost-based BSCs reduce the intra-class
subsidy and produce a decrease in the volumetric price bringing it closer to its cost
based level. The proposal to have both the volumetric price and the BSC closer to
cost based results in dampened seasonal variation in both customer bills and
Sierra’s revenue stream. The chart below demonstrates this.

IV. RULE 9 FACILITIES COSTS
6. Q. HAS THE COMPANY’S CERTIFICATION COST OF SERVICE
PROPOSAL CHANGED FROM THAT PROPOSED BY THE COMPANY
IN ITS DIRECT FILING?
A. No. The Company continues to propose a cost of service study and class revenue
requirement including Rule 9 facilities as an allocation factor. Ms. Shelton
Patchell’s prepared direct and certification testimonies explain the incorporation of
the Rule 9 facilities into the gas cost of service study and the facilities study itself.
As she explains, inclusion of Rule 9 facilities is in response to the Commission’s
Order in Docket 13-06003, in which Sierra was ordered to include information on
the costs of Rule 9 facilities in the determination of cost based BSC. The updated
Rule 9 facilities are used to split out a portion of the Distribution Mains function to
a new category, Customer Rule 9 Mains in the certification cost of service study.
This is a better reflection of cost causation as it identifies a component of cost that
is directly tied to each class rather than continuing to utilize a less informed
allocation of Distribution Mains plant which is based on system peak demand.
Because Rule 9 facilities are local facilities, closest to the customer, and designed
to meet that customer’s individual planned maximum demand the cost causation
can be directly linked to each class. Once installed, these costs are relatively fixed
in nature. Therefore, identifying the Rule 9 facilities on a typical customer basis by
class is appropriate. As explained in the prepared direct testimony, the investment
per customer and estimate of the Rule 9 facilities plant additions were calculated to
reflect how investments were made over time in order to appropriately remove them
from Distribution Mains Plant. Ms. Shelton-Patchell’s testimony discusses this
process and the certification results.

7. Q. SHOULD THE RESULTING CERTFICATION COST ALLOCATIONS
AND RATES DRIVEN BY THOSE COSTS BE APPROVED?
A. Yes. For the reasons stated above and in my prepared direct testimony and that of
Mrs. Shelton-Patchell, the certification gas cost study and resulting gas prices
should be approved.
8. Q. DOES THIS COMPLETE YOUR PREPARED CERTIFICATION
TESTIMONY?
A. Yes.

6. Q. WHAT ADJUSTMENTS HAVE BEEN MADE TO THE DIRECT FILING
IN EXHIBIT SHELTON-PATCHELL CERTIFICATION-2?
A. Sierra has updated Statements F (cost of capital), I (revenue requirement) and J
(revenues) to recognize changes in results of operations through May 31, 2016.
Statements F, I and J contain, among other things, changes in rate of return,
expense levels, investment amounts, present rate revenues and sales that occurred
during the 12-month Certification period ended on May 31, 2016.
Exhibit Shelton-Patchell Certification-2 reflects the update to Sierra’s rate of
return for the natural gas division from 6.23% to 5.94%, changes in expense and
investment levels occurring during the certification period, and changes in present
rate revenues. As a result of these certification updates, the revenue requirement
required by Sierra’s gas operation to earn its proposed rate of return decreased
from a reduction of $8,000 in the direct filing (see Statement H) to a reduction of
$1,544,000 in this certification filing (see Statement I).
In addition to the revenue requirement updates, Exhibit Shelton-Patchell
Certification-2 reflects a correction to the Rule 9 Facilities Study. In reviewing
the Rule 9 Facilities Study, it was noted that two projects for Large Commercial
Natural Gas (“LCNG”) customers were duplicated and that total project costs for
projects that were for multiple rate classes were reflected in each rate class. The
two duplicate LCNG projects were removed from the study and project costs that
were for multiple rate classes were disaggregated to each rate class using the
number of meters assigned to each rate class. The results of the corrected Rule 9
Facilities Study are shown in Exhibit Shelton-Patchell Certification-5.

SHELTON-PATCHELL DIRECT-2 AND EXHIBIT SHELTON
PATCHELL CERTIFICATION-2?
A. Changes in revenue requirement and the Rule 9 Facilities Study corrections drive
the differences between Exhibit Shelton-Patchell Direct-2 and Exhibit Shelton-
Patchell Certification-2. Between the direct filing and the certification filing,
sales and throughput for all customers and some allocators changed. These

changes to inputs produced small changes in the final allocation of costs between
rate classes. Present rate revenues were also updated for certification, causing the
percent-of-change calculation to change.
9. Q. DID YOU UPDATE EXHIBIT SHELTON-PATCHELL DIRECT-6,
WHICH WAS DISCUSSED IN Q&A 29 OF YOUR DIRECT
TESTIMONY?
A. Yes. As discussed in my direct testimony, changes in the Customer Weighting
Factor Study (“CWFS”), the Demand Study, the Meter Study and the Rule 9
Facilities Study resulted in significant cost shifts between classes. Exhibit
Shelton-Patchell Certification-6 updates the exhibit in my prepared direct
testimony and separately shows the impact of the Rule 9 Facilities Study
corrections discussed above. Line 1 shows the revenue requirement using the
customer weighting factor, demand and meter studies from Docket No. 13-06003.
The isolated changes dues to the customer weighting factor, demand, meter and
facilities studies are shown on lines 4 through 7. Line 8 shows the impact of the
corrections made to the Rule 9 Facilities Study.
10. Q. HOW HAS STATEMENT O CHANGED, GIVEN THE RESULTS OF
EXHIBIT SHELTON-PATCHELL CERTIFICATION-2?
A. The changes in Statement O mainly relate to the change in the revenue
requirement. All classes show a decrease consistent with the overall decrease in
revenue requirement.

11. Q. WHAT ARE THE RESULTS OF CERTIFICATION STATEMENT O?

Compared to the direct filed Statement O, all of the customer classes, except
Transportation, experienced a decrease in class revenue requirement. Also, the
percentage changes are consistent with the percentage changes from Shelton-
Patchell Certification-2.

12. Q. PLEASE UPDATE THE CUSTOMER COSTS THAT ARE THE BASIS
FOR SETTING THE BASIC SERVICE CHARGES THAT WERE FIRST
DESCRIBED IN Q&A 33 OF YOUR DIRECT TESTIMONY.
A. Between the direct filing and the certification filings, the Customer Costs for
various classes have been updated and decline as result of the lower revenue
requirement associated with the reduction in the rate of return for the natural gas
department mentioned above. Except for the Transportation class, the reduction
in the Customer Costs are not significant enough to change the Basic Service
Charges that are proposed in Sierra’s direct filing. The cost reductions for each
class are:
• Residential Natural Gas (RNG): From $17.36 to $16.98.
• Residential Propane (LPG): From $17.24 to $16.86.
• Small Commercial Natural Gas (SCNG): From $46.48 to $41.70.
• Small Commercial Propane (LPG): From $50.12 to $44.87.
• Large Commercial (LCNG and LPG): From $1,065.60 to $1,075.96.
• INGR: From $2,504.85 to $2,360.35.
• Transportation: From $1,030.34 to $588.27.
Although the Customer Costs for the Transportation class have gone down by
43%, Sierra continues to propose that the per-meter-per-month charge for the
Transportation class be set at the same rate as proposed for large commercial
customers, or $1,000, to remain consistent with the requirement stated in the tariff.

13. Q. WERE THE ALTERNATE COST STUDY AND ALTERNATIVE
STATEMENT O DISCUSSED IN Q&A 40 OF YOUR DIRECT
TESTIMONY UPDATED?
A. Yes. The alternate Cost Study that does not include the effects of the Rule 9
facilities cost breakout was updated and is Exhibit Shelton-Patchell
Certification-7. Exhibit Shelton-Patchell Certification-8 is the updated
alternative Statement O with rates that do not include the effects of the Rule 9
facilities cost break-out. Exhibit Shelton-Patchell Certification-9 compares the
rates proposed in Statement O with the alternate rates from Exhibit Shelton-
Patchell Certification-8.
