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. 1,500 = 3 x 12,000 = 36,000 Program Capacity 500 PAGE 45 30,000 - 2.5 × $100/ton = $250.00 Rebate Amount 12,000 Example B: A person in a 2,000 square foot house installs a 60,000 BTUH central air conditioner with a SEER rating of 12.0. 2,000 = 4 x 12,000 = 48,000 Program Capacity 500 48,000 - 4 x $100/ton = $400 Rebate Amount 12,000 Example C: A person in a 2,000 square foot house installs a 60,000 BTUH central heat pump with a SEER rating of 12.0. 2,000 - 4 x 12,000 = 48,000 Program Capacity 5O0 48,000 = 4 x $100/ton = $400 Rebate Amount Minimum SEER/EER Central Air Conditioninq Ratinq Incentive Single Phase (SEER) 12.0 $100 / ton*t Three Phase (EER) 12.0 $100 / ton Central Heat Pumps Single Phase (SEER) 12.0 $100 / ton Three Phase (EER) 12.0 $100 / ton Room Air Conditioners 10.0 $ 50 / unit Room Heat Pumps 10.0 $ 50 / unit Geothermal Heat Pumps 12.0 $500 / unit * Refer to "1992 Appliance Rebate Program: Methods Used in Determining Equipment Efficiency and Eligibility" t For calculation purposes, one ton equals 12,000 BTUH PAGE 46 SCHEDULE MTR 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 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.

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 PAGE 51 SPECIAL FACILITIES RIDER (1) Ail service shall be offered from available facilities.
