I. Introduction

Weather Normalization Adjustment (WNA) is standard within the natural gas utility industry and protects the customer and the natural gas provider. During the November through April billing periods, when customers’ bills are most sensitive to increased usage during a colder winter, residential and commercial customers will notice a line item called “Rider WNA” on their gas bill. The WNA refunds over-collections when weather is colder than normal and surcharges under collections when weather is warmer than normal. In this way, WNA helps remove variances on a customer’s bill caused by abnormal weather during the heating season. This report is intended to provide information on how WNA is calculated, and specifically the data that was used to calculate the Rider WNA on a customer’s bill during the 2019–2020 heating season. The report includes an explanation of how the WNA Factor is calculated (Section II), the monthly WNA Factors that resulted from the weather in the most recent heating season (Section III), the weather stations that are used for each city served by the Atmos Energy Mid-Tex Division (Appendix A), applicable WNA tariffs (Appendices B, C, D, and E) the base rates for temperature sensitive sales (Appendix F), normal and actual heating degree days for the prior year’s heating season (Appendices G, H, I, and J), and a sample bill calculation with step by step instructions for how to calculate the Rider WNA on a customer’s bill (Appendices K & L).

II. Computation of Weather Normalization Adjustment Factor

The Weather Normalization Adjustment Factor (WNAF) is calculated to the nearest one-hundredth cent per unit of gas (Ccf) by the following formula: (HSF x (NDD-ADD) ) WNAF = R x (BL + (HSF x ADD) ) Where

WNAF = Weather Normalization Adjustment Factor expressed in dollars per Ccf R = base rate of temperature sensitive sales expressed in dollars per Ccf (i.e.,

consumption charge rate from customer’s bill) (see Appendix E) BL = base load sales as stated on applicable WNA tariff (see Appendices B, C

or D) HSF = heat sensitivity factor by weather station as stated on applicable WNA

tariff (see Appendices B, C and D) NDD = billing cycle normal heating degree days, calculated as the simple ten-

year average of actual heating degree days (see Appendix F, G and H) ADD = billing cycle actual heating degree days, calculated by taking 65°F minus

the average of the high and low temperature, when the average temperature is below 65°F (see Appendix F, G and H)

The Weather Normalization Adjustment is computed as: WNA = WNAF x q

Where

WNA = Rider WNA as shown on a customer’s bill q = relevant sales quantity expressed in Ccf (i.e., “Usage in CCF” from

customer’s bill)

III. Monthly WNA Factors

The following tables represent the factors used to calculate the Weather Normalization Adjustment Factors (WNAF) for each calendar month during the 2019-2020 WNA season. It should be noted that the WNA Factor used to calculate the “Rider WNA” on a customer’s bill will differ from those shown below, as the heating degree days (NDD and ADD) are based on the customer’s specific billing cycle and not the calendar month.

Appendix K – Rider WNA Calculation Instructions


Page 68

Step 1. Get copy of Atmos Energy bill in question

Before calculating your Rider WNA adjustment, you will need a copy of your Atmos Energy bill in question. If you don’t already have a copy of your bill, you can retrieve a copy from the Atmos Energy Account Center at atmosenergy.com. If you have already registered your account online, just click the login button in the upper left corner of the screen. If you have not registered your account online, now is a great time to do so. Just click register.

If the bill is for a residential or commercial customer and is from a billing period between November 2019 and April 2020, it should include a Rider WNA line under “Current Gas Charge Total”. This report will assist you in verifying this Rider WNA adjustment amount.

Step 2. Identify weather station

Next identify which weather station applies for the city where your gas meter is located. You can find this in Appendix A. Simply look for your city in the first column. Once you find your city, note the weather station listed in the second column. It will be one of the following: Abilene, Austin, DFW, Waco, or Wichita Falls.

Step 3. Identify Base Load (BL) and Heat Sensitivity Factors (HSF)

Several of the factors in the WNA calculations are dependent on which tariff is applicable to you. If you are a customer in an incorporated city other than Dallas, you will use the tariffs included in Appendix B & E. If you are a customer in the City of Dallas, you will use the tariff in Appendix C. If you are a customer in an unincorporated area, you will use the tariff in Appendix D.

Find the Base Use/Heat Use Factors table in the applicable tariff. Next, find the row that applies to the weather station you identified in step 2. If you are a residential customer, you will use the Base Use and Heat Use Factors in the first two columns, while commercial customers will use these factors from the last two columns.

Note the base use factor as BL and the heat use factor as HSF.

Step 4. Identify Base Rate (R)

Base rate information can be found in Appendix F. Identify the applicable base rate by referencing Table F-1 (incorporated cities under the RRM Tariff), Table F-2 (incorporated cities within the ATM Coalition) Table F-3 (City of Dallas) and Table F-4 (unincorporated areas), for the correct billing period (month when bill was issued) and customer type (residential or commercial). For verification, this rate should match the rate on your bill under “CURRENT GAS CHARGE TOTAL” next to “CONSUMP CHRG”.

Note this base rate as R.

Step 5. Calculate heating degree days (NDD and ADD).

The heating degree days are based on the actual days included in your billing period. On your bill, note the “from” and “to” service dates in the table in on the right side of the bill. Heating degree data can be found in Appendix G & J for customers in an incorporated city other than Dallas and Appendix H if you are a customer in the City of Dallas and Appendix I for customers in unincorporated areas. Once you locate the correct appendix, add the Normal Heating Degree Days (NDD) from the day before the first date of the billing period (i.e., FROM) to the day before the last date of the billing period (i.e., TO).

Note this total Normal Heating Degree Days as NDD.

Then add the Actual Heating Degree Days (ADD) from the day before the first date of the billing period (i.e., FROM) to the day before the last date of the billing period (i.e., TO).

Note this total Actual Heating Degree Days as ADD.

Step 6. Calculate WNA Factor

The WNA Factor can be calculated using the formula in Section II using each of these factors (BL, HSF, R, NDD, ADD)

Step 7. Identify Sales Quantity of Natural Gas (q)

From your applicable bill, find the “ACTUAL USAGE IN CCF” number in the table on the right.

Note this relevant sales quantity as q.

Step 8. Calculate Rider WNA

The Rider WNA amount can be calculated by multiplying the WNA Factor calculated in Step 6 by the relevant sales quantity (q) identified in Step 7.

Step 2. Identify weather station (Appendix A)

Weather station is .

Step 3. Identify Base Load (BL) and Heat Sensitivity Factors (HSF) (Appendix B, C, D, D.1 or E)

BL =

HSF=

Step 4. Identify Base Rate (R) (Appendix F)

R= $ /Ccf

Step 5. Calculate heating degree days (NDD and ADD) (Appendix G, H, I, I.1 or J)

NDD =

ADD =


(HSF x (NDD-ADD) ) WNAF = R x (BL + (HSF x ADD) )

WNAF = $ /Ccf

Step 7. Identify Sales Quantity of Natural Gas (q) (Customer bill in question)

q = Ccf


Rider WNA = $

Step 2. Identify weather station (Appendix A)

Weather station is Wichita Falls .

Step 3. Identify Base Load (BL) and Heat Sensitivity Factors (HSF) (Appendix B, C, D, D.1 or E)

BL = 11.40

HSF= 0.14680

Step 4. Identify Base Rate (R) (Appendix F)

R= $0.17423/Ccf

Step 5. Calculate heating degree days (NDD and ADD) (Appendix G, H, I, I.1 or J)

Billing cycle is 1/4/2020 through 2/4/2020 (subtract one day from start/end date for NDD and ADD calculations).

NDD = 719

ADD = 546


((HSF x (NDD-ADD)) WNAF = R x ((BL + (HSF x ADD)) ((0.1468 x (719 - 546)) WNAF = 0.04071 x (11.40 + (0.1468 x 546)) WNAF = $0.0483314/Ccf Step 7. Identify Sales Quantity of Natural Gas (q) (Customer bill in question)

q = 75 Ccf


Rider WNA = WNAF x q

Rider WNA = 0.0483314 x 75

Rider WNA = $3.62
