This rider is available to the customers who receive service
from Rate Schedules GSS, GSL, or TGS.
APPLICATION
This rider is available to electric service supplied at any one
location. It is for firm electric service applicable to new and
existing customers as described below, over a five year period.
This rider is available to the following classes of customers:
(1) New customers whose electric service represents demand not
previously served by the City at any location in the
City's service area in the last 12 months, where such
metered demand will be in excess of 225 KVA or 200 KW, as
estimated and mutually agreed upon by the Director of
Electric Utilities and the customer.
(2) Existing customers served under Rate Schedules GSS, GSL or
TGS who increase their prior existing metered demand by
225 KVA or 200 KW. This increase shall be verified by
comparing a three month rolling average of the new level
of demand to the prior demand averaged for corresponding
months. During periods in which this verification method
cannot be applied, the Director of Electric Utilities and
the customer may develop a mutually agreed upon formula to
estimate the base and additional demand levels.
NET MONTHLY RATE
The customer shall be charged under the appropriate applicable
rate schedules with the exception that the monthly billing demand
(For GSS and GSL) or system demand and on-peak demand (For TGS)
will be adjusted in accordance with the following table:

A design shall be submitted to the Director of Electric Utili-
ties for approval. The thermal storage equipment shall be checked
for input electric demand (KVA) and output capacity (BTU). The
system shall be limited for incentive payment to a maximum of
12,000 BTU per 500 square feet for the conditioned area of the
facility to be served, if such facility is used for office
purposes. If the facility is used for other purposes, such as, for
example, an industrial use, the customer may request an exception
from the City of Denton Electric Utility. The City Electric
Utility will study the request for exception and make recommenda-
tions to the Electric Utility Director and the Executive Director
of Utilities as to whether a different formula should be used. The
decision of the Executive Director of Utilities will be final.
Upon completion, the input-output of the thermal storage units
will be measured by the City of Denton. The customer may observe
and verify all information and calculations for the actual size of
the facility. Auxiliary equipment used to circulate fluid or air
handlers which would operate under normal peak periods will not be
included in calculating the KVA load for incentive payments.

APPLIANCE REBATE
(Effective 10/01/95)
Application/Proqram Summary
The City of Denton Utility Department is offering cash payments
to customers who purchase and install high efficiency air condi-
tioners or heat pumps in new or existing residential or commercial
facilities.
The program's objective is to reduce energy demand and consump-
tion, thereby saving customers dollars on their utility bills and
reducing the peak load of the City of Denton's electric system.
Proqram Guidelines
1. All installations must be for accounts served by the City
of Denton Utility Department and must meet all applicable
national, local, and manufacturers' codes and specifica-
tions.
2. To qualify for a rebate, equipment must be new when in-
stalled.
3. All equipment must be purchased. No leased or lease/
purchased equipment will qualify for a cash rebate.
4. Installations must be made by licensed contractors and/or
dealers.
5. No rebate will be paid on a partial replacement of an air
conditioner. The compressor, condenser and the evaporator
coil must be replaced to qualify for a rebate.
6. Payments for residential central cooling systems, which
include apartments and mobile homes, will be limited to a
capacity based on a minimum of 500 conditioned square feet
per ton.
7. The conditioned area in square feet is required on each
residential central system request for payment.
8. The rebate will be paid to the purchaser of the qualifying
equipment upon verification of compliance with program
guidelines.
9. Requests for payment must be received by the Director of
Electric Utilities within 60 days of installation.
PAGE 42
10. Equipment and installation are subject to inspection by
the City's Building Inspection Department before final

I. GENERAL PROCEDURES
A. Application
To determine who qualifies for a rebate, an appli-
cation for rebate must be completed and sent to the
Director of Electric Utilities within 60 days of
installation of the equipment. Participating
dealers have rebate application forms and will
complete these forms for the purchaser. It is the
purchaser's responsibility to see that the dealer
completes the form and submits it to the Director
of Electric Utilities.
B. Inspections
Installations of central systems will be inspected
by the City's Building Inspection Department and
must be approved before rebates will be processed.
C. Payments to Participants
Cash payments will be made to the purchaser of the
qualifying equipment. Participating retail equip-
ment dealers will receive a cash payment of $20 per
unit for the sale of window units, central air
conditioning systems, or heat pumps to offset their
cost for properly filling out the applications for
purchasers. Program participants are responsible
for submitting the correct,information. The Utili-
ty Department will not issue any additional payment
unless the payment was incorrect due to a mistake
in processing by a City employee.
1. The twenty dollar ($20.00) payments to
dealers will be made only if they supply the
qualifying equipment to the customer or
builder who is paying for the installation
of the equipment. Dealers and purchasers
may be denied payment for failure to follow
program guidelines such as: failing to
supply correct square footage or SEER/EER
figures; installing equipment which is not
PAGE 43
new; replacing part of a split system; or
failure to fill out rebate forms properly.
2. Payments will be made to customers who pur-
chase and install new qualifying equipment.
If a tenant purchases and installs qualify-
ing equipment, the payment is made to the
tenant. If the owner of rental property
purchases and installs qualifying equipment,
the payment is made to the owner. If the
purchaser of a mobile or custom home selects
and pays for a qualifying unit, the purchas-
er will receive the rebate.
II. CENTRAL ELECTRIC AIR CONDITIONERS AND HEAT PUMPS
A. A new condensing unit with an inside evaporator
coil will qualify if matched, as specified, in the
current issue of the ARI Directory of Certified Air
Conditioners and Air Source Heat Pumps and the unit
meets the minimum ratings as specified in the 1992
Appliance Rebate Program. If the unit is not in
the current ARI Directory, the manufacturer's
latest data approved for publication will be ac-
cepted.
If the unit is not in the current ARI Directory or
data approved for publication, the average of the
high and low SEER/EER coil only, not including
blower coil, will be accepted as listed in the
current ARI Directory.
B. Computer simulations may be used if ratings are not
listed in the current ARI Directory, provided the
following criteria are met:
1. Systems using mix-matched coils must meet
all established program guidelines to quali-
fy for a rebate.
2. The computer simulations must be signed,
certified, and dated by a registered profes-
sional enqineer and an officer of the compa-
ny making the submittal.
3. The engineer who certifies a simulation must
attest to the accuracy of the input data,
the validity of the calculation procedure
used, and that the results are in accordance
with D.O.E. approved methodology.
4. A complete set of the input data and an
indication of the source of the data must
accompany the simulated ratings.
PAGE 44
5. The simulated ratings must be based on the
condensing unit's tested combination as
listed in the current ARI Directory or
latest data approved for publication and
identified by the correct model numbers of
both the condensing unit and coil as listed
in the current ARI Directory.
6. Simulated ratings must not exceed 105% of
the SEER rating of the tested system used as
a base.
7. An open file of computer simulations will be
maintained at the Energy Management Office.
Supplying erroneous ratings or data can lead
to disqualification of those involved from
further program participation.
C. Program Capacity and Payment Formula
1. The maximum allowable BTU per hour capacity
eligible for a residential rebate is deter-
mined by dividing the square footage of the
conditioned area by 500 and multiplying by
12,000.
Example: The Program Capacity for a 1,500 square
foot house is:
1,500 = 3 0 × 12,000 = 36,000 BTUH
500 '
The City will pay a rebate on a unit that meets
program efficiency standards and is sized at
36,000 BTUH or less.
2. Actual payment will be determined by dividing the
BTUH of the installed unit (up to, and including
the Program Capacity) by 12,000 and multiplying by
the incentive.
The incentive amounts and SEER ratings are refer-
enced on page 5 of the "1992 Appliance Rebate
Program: Methods Used in Determining Equipment
Efficiency and Eligibility," and are incorporated
herein as if fully set forth at length:
Example A: A person in a 1,500 square foot house
installs a 30,000 BTUH central air
conditioner with a SEER rating of 12.0.

PREMIUM-EPPICIENCY MOTOR REBATE
(Effective 10/01/95)
APPLICATION/PROGRAM SUMMARY
The City of Denton Utility Department is offering cash payments
to customers who purchase and install premium-efficiency motors and
adjustable speed drives in facilities serviced by Denton Electric
Utility.
The program's objective is to reduce energy demand and consump-
tion, thereby saving customers dollars on their utility bills and
reducing the peak load of the City of Denton's electric system,
thereby conserving energy and improving the power factor.
PROGRAM GUIDELINES
1. All installations must be for accounts served by the City
of Denton Electric Utility and must meet all applicable
national, local, and manufacturers' codes and specifica-
tions.
2. To qualify for a rebate, equipment must be new when in-
stalled. All equipment must be purchased; no leased or
lease/purchased equipment will qualify for a cash rebate.
Removed motors must be properly disposed of after inspec-
tion and not re-used with the Denton Electric Utility
system. Method of disposal must be stated.
3. The City will pay the rebate to the purchaser of the
qualifying equipment upon verification of compliance with
program guidelines.
4. Equipment and installation are subject to inspection by
the City's Electric Utility before final approval for
payment is issued.
5. Replacement motors must be the same horsepower or lower
than the original motor. Exceptions must be approved in
writing by the City's Electric Utility. Only motors 20
horsepower and above are eligible for the program.
6. All information must be complete on the Motor Rebate
Application in order for a rebate to be issued (see Motor
Rebate Application).
7. The Premium-Efficiency Motor Rebate program guidelines and
payments are subject to change without notice. This
program may be discontinued with prior notice, at any time
by the City of Denton Electric Utility.
PAGE 47
REBATE METHODOLOGY
Rebates for the Premium-Efficiency Motor Rebate Program will be
based on the following methodology:
REPLACEMENT MOTORS:
1. The Denton Electric Utility staff will visit the site to
determine the existing motors efficiency. If the existing motor is
non-operational, an estimate will be made.
2. The customer must provide all information on the rebate
application concerning the proposed motor purchase.
3. A new motor must not exceed the horsepower of the existing
motor without express written consent by the Denton Electric
Utility, which consent shall be given only if the utility finds an
increased efficiency.
4. The information concerning the existing and the proposed
motors will be entered into the Motor Master software program to
calculate the kilowatt (KW) or kilovolt amperes (KVA) savings yield.
The calculation is based on horsepower, efficiency, RPM, and load
information.
5. The KW or KVA yield will be multiplied times the rebate
incentive amount of $100/KW or $90/KVA:
KW yield x $100 / KW
or KVA yield x $ 90 / KVA
6. The Denton Electric Utility will to the site to verify
installation, and following successful installation, a rebate check
will be mailed to the customer.
NEW MOTORS:
New motors will follow the procedure outlined above for
replacement motors but the efficiency comparison will be made
against a standard new motor, to be determined by the Motor Master
software program used by the City, Department of Energy standards,
or the Denton Electric Utility.
ADJUSTABLE SPEED DRIVES:
The Denton Electric Utility will visit the customer site to
determine KW/KVA savings from the proposed Adjustable/Variable Speed
Drive. Those savings will be awarded on a $100/KW or $90/KVA basis.
A watt meter will be used before and after installation.
KW / KVA SAVINGS:
Rebates in excess of $1,000.00 require advance approval of the
Director of Electric Utilities.

ENERGY COST ADJUSTMENT
(Effective 10/01/95)
ENERGY COST ADJUSTMENT
All monthly KWH charges shall be increased or decreased by an
amount equal to "X" cents per KWH, to be known as the energy cost
adjustment (ECA). The ECA shall be computed during the last month
of each fiscal year quarter (December, March, June and September) to
be applied to the quarter immediately following. The City shall in
no case change the energy cost adjustment more than once in any
three (3) month period. The ECA shall be calculated using the
following formula:
Projected enerq¥ cost for next quarter
ECA =
Projected KWH sales for next quarter
In the event that actual plus estimated cumulative costs of
fuel, variable costs of Texas Municipal Power Agency (TMPA) energy
and purchased energy (excluding TMPA's fixed charges) are greater
than or less than the actual and projected ECA revenues by $500,000
or more during the next quarter, the Director of Electric Utilities
or his designate shall recompute the Energy Cost Adjustment and may
re-establish an ECA that collects or returns such difference over
the next three month period. Such change in ECA shall be applied
evenly to each month during the three month period.
The above formula results in an October - December 1995
estimated ECA as follows:
ECA = 1.70¢ / KWH
