Advice Letter No. 517 November 27, 2019

PUBLIC UTILITIES COMMISSION OF NEVADA

Southwest Gas Corporation tenders herewith for filing the following tariff sheets applicable to its Nevada Gas Tariff No. 7:

Proposed PUCN Sheet No. Supersedes PUCN Sheet No. 57th Revised Sheet No. 10 56th Revised Sheet No. 10 57th Revised Sheet No. 11 56th Revised Sheet No. 11 56th Revised Sheet No. 12 55th Revised Sheet No. 12 56th Revised Sheet No. 13 55th Revised Sheet No. 13

The purpose of this filing is to adjust rates to reflect the change in the quarterly Gas Cost rate, effective January 1, 2020. The quarterly Gas Cost rate includes two components, the Base Tariff Energy Rate (BTER) and the Deferred Energy Account Adjustment (DEAA). In Southern Nevada, the BTER will increase by $0.00017 per therm. The DEAA will increase by $0.02500 per therm. As such, the overall change in the Southern Nevada Gas Cost rate will be an increase of $0.02517 per therm. This results in an increase in annualized revenue of $11,436,576. The calculation of Southern Nevada’s annualized revenue change is attached in Schedule 1. In Northern Nevada, the BTER will increase by $0.00278 per therm. The DEAA will increase by $0.02500 per therm. As such, the overall change in the Northern Nevada Gas Cost rate will be an increase of $0.02778 per therm. This results in an increase in annualized revenue of $2,873,961. The calculation of Northern Nevada’s annualized revenue change is attached in Schedule 2. Customers are being notified of the rate changes by means of a bill insert included with each bill beginning approximately December 1, 2019. Copies of the bill inserts are attached. This filing is made in accordance with the Nevada Administrative Code, Chapter 703, of the Commission’s Rules of Practice and Procedure. Respectfully submitted, SOUTHWEST GAS CORPORATION

INFORMATIONAL TRACKING DATA

PURSUANT TO THE ORDER IN

DOCKET NO. 18-08016

Docket No. 18-06016 Cost Tracking Overview

Pursuant to ordering paragraphs 3, 4, and 5 of the April 19, 2019 order issued in Docket No.

18-08016, Southwest Gas submits the informational data contained on Exhibits A and B and

Confidential Exhibits C and D. This information relates to the gas flow months of July 2019

through September 2019 or the August 2019 through October 2019 accounting period

(Reporting Period). An overview of the information included on each of the exhibits is

provided below.

Exhibits A & B

The information summarized for Southwest Gas’ Southern Nevada and Northern Nevada rate

jurisdictions, provided on Exhibits A and B, respectively, for the Reporting Period includes: 1)

Southwest Gas’ intraday purchases; and, 2) a non-confidential summary information of

excess imbalance charges paid by both special contract and non-special contract

transportation customers.

Exhibits C & D

Confidential Exhibits C and D contain the same summary information for the Southern

Nevada and Northern Nevada rate jurisdictions, respectively, but individually identify each

special contract transportation customer’s information.

The Company did not make any intraday purchases during the Reporting Period for either

rate jurisdiction and there were no instances where Southwest Gas avoided making an

intraday purchase due to over-deliveries by transportation customers in either rate

jurisdictions during the Reporting Period. Consequently, there were no costs or potential

savings associated with under- or over-deliveries by transportation customers. Southwest

Gas will make available confidential individual transportation customer information to the

Commission’s Regulatory Operations Staff and the Bureau of Consumer Protection upon

execution of a Protective Agreement.
