EXHIBIT A 2022 RRM Rate Tariffs MID-TEX DIVISION ATMOS ENERGY CORPORATION RIDER: WNA—WEATHER NORMALIZATION ADJUSTMENT APPLICABLE TO: ALL CUSTOMERS IN THE MID-TEX DIVISION UNDER THE RRM TARIFF EFFECTIVE DATE: Bills Rendered on or after 10/01/2022 Provisions for Adjustment The Commodity Charge per Ccf (100 cubic feet) for gas service set forth in any Rate Schedules utilized by the cities of the Mid-Tex Division service area for determining normalized winter period revenues shall be adjusted by an amount hereinafter described, which amount is referred to as the "Weather Normalization Adjustment." The Weather Normalization Adjustment shall apply to all temperature sensitive residential and commercial bills based on meters read during the revenue months of November through April. The five regional weather stations are Abilene, Austin, Dallas,Waco, and Wichita Falls. Computation of Weather Normalization Adjustment The Weather Normalization Adjustment Factor shall be computed to the nearest one-hundredth cent per Ccf by the following formula: (HSFi x (NDD-ADD)) WNAFi = Ri (BLi + (HSFi x ADD) ) Where i = any particular Rate Schedule or billing classification within any such particular Rate Schedule that contains more than one billing classification WNAFi = Weather Normalization Adjustment Factor for the ith rate schedule or classification expressed in cents per Ccf Ri = Commodity Charge rate of temperature sensitive sales for the ith schedule or classification. HSFi = heat sensitive factor for the ith schedule or classification divided by the average bill count in that class NDD = billing cycle normal heating degree days calculated as the simple ten-year average of actual heating degree days. ADD = billing cycle actual heating degree days. Bli = base load sales for the ith schedule or classification divided by the average bill count in that class The Weather Normalization Adjustment for the jth customer in ith rate schedule is computed as: WNA; = WNAFI x Where qij is the relevant sales quantity for the jth customer in ith rate schedule.
