Corrected July 10, 1979 3 - (3) Should the electrical energy furnished under this schedule for any reason be metered on the primary side of the service transformers, the energy metered shall be reduced by 1 1/2 per cent before calculating the energy charge.

(d) Provided however, if a customer has not been on the system a sufficient period of time to establish sufficient demand history to allow calculation of (b) or (c) above, then the utility shall issue a bill using the greater of the current monthly peak measured demand or 75% of the highest previously measured demand as the "billing demand" . (4) Minimum bill : The monthly minimum bill shall be the highest demand charge in' the current or preceding eleven months . (5) Power factor adjustment: A power factor adjust- ment may be made, at the option of the city, when the power factor at the time of maximum monthly demand is less than 85% lagging. If the power factor is less than 85% , the billing demand may be increased as follows : (85% Minus Measured Power Factor) times 1 . 5 times (Current Month Measured Demand) (6) Service facilities : The city shall furnish as a standard installation facilities adequate to supply service at a single point of delivery to a normal load equal to the maximum 15-minute demand of the customer.

(8) Multiple metering : Where two or more demand metering installations are provided, the maximum 15-minute demand shall be determined by adding together the separate demands at each metering installation. However, primary metering may be installed to measure the total demand at one point, if feasible . Where two or more watthour metering installations are provided, the total Kwh used for billing purposes shall be determined by adding together the Kwh metered at each installation. However, the maximum demand and Kwh supplied at two or more premises will not be combined for billing purposes hereunder. (9) Primary service: Customers who take service at primary voltage shall be granted discounts as follows : (a) 1 1/2% of the demand and energy charge where metering is on the high voltage side of city-owned transformers . (b) 5% of the demand charge and 1 1/2% of the energy charge where metering is on the high voltage side of customer-owned trans- formers . (c) Voltages below 8 ,000/13 , 000 Y nominal are considered secondary voltage . (10) Conditions: The Large Power Rate shall be sub- ject (a) to the general condition in subsection 36-8005 (a) , and (b) to the following specific conditions : (1) The customer ' s total usage on a single premise shall determine whether the customer qualifies for service under this rate structure. In no event will the customer be billed on both the general power and large power rates. A premise is defined as the main building of a commercial or industrial establishment, and shall include the outlying or adjacent buildings used by the same provided the use of service in the outlying buildings is supple- mental and similar to the service used in the main building. (2) Fluctuating loads. If use of energy is intermittent or subject to violent fluctuation, the city may add to the 15-minute measured demand an amount equal to 65% of the rated capacity in Kw of apparatus which causes such fluctuations . Section 36-8005 (d) . The standard approved type of electric water heater shall have a single 120 volt heating element no larger than 1500 watts or shall have multiple thermostatically controlled noninductive 240-volt heating elements of not more than 5000 watts per element with such multiple elements connected inter- locking so that only one element may operate at a time. Section Three . All ordinances or parts of ordinances in conflict herewith are repealed to the extent of such conflict . Section Four. This ordinance shall be in full force and effect for billing periods ending on or after November 25 , 1979 and after its publication as required by law. . - 6 - Enacted this 24th day of July , 1979.
