APPLICABLE TO: ALL CUSTOMERS IN THE MID-TEX DIVISION UNDER THE RRM TARIFF
EFFECTIVE DATE: Bills Rendered on or after 12/01/2021 PAGE:
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 jth 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;= WNAF; x
Where qq is the relevant sales quantity for the jth customer in ith rate schedule.
