SECTION 2D OF THE ORDINANCE AND ADDING A NEW SECTION 2D
TO ORDINANCE NO. 10849.
BE IT ORDAINED BY THE CITY COUNCIL OF THE CITY OF FORT WORTH,
TEXAS:
Section 1. Effective upon the date of final passage and
approval of this ordinance, Ordinance No. 10849 is amended.
Section 2. Section 2D of Ordinance No. 10849 is deleted.
Section 3. A new Section 2D as set forth below is added to
Ordinance No. 10849.
Section 2D
Weather Normalization Adjustment
Effective with bills rendered during the October 1992
through May 1993 billing months, and annually thereafter
for the October through May billing months, the above
residential and commercial consumption rates for gas
service will be subject to a weather normalization
adjustment each billing cycle to reflect the impact of
variations in the actual heating degree days during the
period included in the billing cycle from the normal
level of heating degree days during the period included
in the billing cycle. The weather normalization
adjustment will be implemented on a per Mcf basis and
will be applicable to the heating load of each customer
during the period included in the billing cycle. It will
be determined separately for residential and commercial
customers based on heating degree data recorded by the
D/FW weather station. The adjustment to be made for each
billing cycle will be calculated according to the
following formula:
NDD - ADD
WNA = ADD x M x AHL
Where WNA = Weather normalization adjustment
NDD ~. Normal heating degree days during
the period covered by the billing
cycle
ADD = Actual heating degree days during
the period covered by the billing
cycle
M = Weighted average margin per Mcf
included in the commodity portion of
the rates effective during the
October through May billing months
AHL = Actual heating load per customer
The heating load to which the weather normalization
adjustment is to be applied for residential customers is
determined by subtracting the residential class base load
from the total volume being billed to the customer. The
heating load to which the weather normalization
adjustment is to be applied for commercial customers is
determined by subtracting the base load for the customer
from the total volume being billed to the customer. The
base load of a customer is the average level of
nonheating consumption.
The weather normalization adjustment is subject to a 50~
limitation factor based on temperatures being fifty
percent warmer or colder than normal. The weather
normalization adjustment will be calculated to the
nearest $.0001 per Mcf.
Section 4. It is hereby found and determined that said
meeting at which this ordinance was passed was open to the public,
as required by Texas law, and that advance public notice of the
time, place and purpose of said meeting was given.

SUBJECT REVISION OF LONE STAR GAS COMPANY'S WEATHER NORMALIZATION ADJUSTMENT
RECOMMENDATION:
It is recommended that the City Council:
1. Adopt the attached ordinance amending Ordinance No. 10849 to revise the
calculation of the Weather Normalization Adjustment.
BACKGROUND:
Lone Star Gas Company rates in effect for Fort Worth were approved by City Council in
M&C G-9158 and were established by Ordinance No. 10849 adopted May 28, 1991. This
ordinance contains an innovative Weather Normalization Adjustment (WNA) clause designed
to stabilize the level of revenue approved by the City Council that would be produced
under conditions of normal weather.
The WNA has been in effect for one heating season, and it has worked as designed.
After the first year's experience, however, Lone Star Gas Company and City staff feel
that the WNA can be refined.
The current WNA is applicable to customers' bills rendered in the months of October
through April. This period does not include all of the heating degree days for all of
the customers. Uniform application of the WNA through the billing cycles is
accomplished by extending the period through the month of May.
The current WNA is applied to all commercial and residential gas used during the
applicable period. The revised formula contains a provision to exempt non-weather-
related gas from the WNA.
The calculation of the WNA is particularly sensitive to actual temperatures at the
beginning and end of the heating season. The revision limits the heating degree days
used in the calculation to be within a range of ± 50% of the normal heating degree
Gays.
These revisions will result in a fair and uniform application of the Weather
Normalization Adjustment.
FISCAL INFORMATION/CERTIFICATION:
This Council action will not require the expenditure of City funds.
