(A) Three-phase service - minimum installation. Three-phase service will be supplied only where Avilla has the lines available, but no connection will be made for less than five horsepower, nor will the bill be based upon less than four kilowatts.
(B) Determination of customer’s demand.
(1) The monthly kVA billing demand shall be normally determined by measurement of taking the highest 15 minute integrated, or equivalent thermal kW capacity, and dividing same by the average monthly power factor, as may be determined by a ratcheted kVARh meter, or by the average monthly power factor, as may be determined by Avilla via periodic tests using suitable metering equipment. The monthly kVA billing demand may also be determined by means of other suitable indication or recording metering equipment. All kVA billing demand shall be determined to the nearest whole kVA.
(2) The billing demand may be adjusted where highly fluctuating or intermittent loads (such as welding machines, electric furnaces, hoists, cranes, elevator, x-ray equipment, and the like) are in operation by customer. Avilla reserves the right to determine the billing capacity by averaging customer’s total load over a two-minute period.
(3) Customer’s demand upon Avilla’s facilities will be determined by permanently installed meters of suitable design. Any demand resulting from unusual conditions, not conducive to practical or accurate metering, will be estimated and added, for billing purposes, to the measured demand.
(4) When more than one demand meter is used to determine customer’s demand upon Avilla’s facilities, the kilowatts of demand that are used in computing the bill shall be based upon:
(a) The sum of the maximum demands of the several meters, without any consideration of their time of occurrence in the month, when the use of more than one meter is required by customer; or
(b) The sum of the simultaneous demands of the several meters, as near as can be reasonably determined, when the use of more than one meter is required by Avilla.
(5) The billing demand applicable for all customers shall be based upon the total demand established by customer in the month being considered, but with the further provision that the demand charge shall not be based upon less than 60% of the highest demand established in any of the immediately preceding 11 months, or less than the minimum demand provided for in the applicable rate.
(6) The billing demand applicable for service shall be determined as is stated in the rate available for that service.
(C) Voltage measurement and billing. All measurements will be made at the voltage stated in the rate, unless it is necessary and practical that Avilla measure at some other voltage. All bills will be computed at the voltage stated in the rate.
