    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:

    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.

    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.

    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.

    all classes except for INGR experienced a decrease in the cost-based results. This

    information updates the amounts discussed in Q&A 28 of my prepared direct

    testimony.

    8. Q. WHAT EXPLAINS THE DIFFERENCES BETWEEN EXHIBIT

    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.

    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.
