Section 29.49.020 -- Definitions
|
|
a. "Network general service" means service to any general service customer which is provided through an underground distribution network supplied by the Broad Street, Massachusetts Street or Union Street Substations, except for service to customers who are certified by Seattle City Light as having predominantly residential use of electricity.
|
|
Section 21.49.055
|
|
A. Medium network general service provided to customers who have in the previous calendar year half or more than half of the normal billings at 50 kW of maximum demand or greater and have more than half of their normal billings at less than 1,000 kW of maximum demand. Classification of new customers will be based on Seattle City Light's estimate of maximum demand in the current year.
|
|
B. For customers metered on the primary side of a transformer, Seattle City Light will either program the meter to deduct computed transformer losses or provide a discount for transformer losses by reducing the monthly kWh billed by the number of kWh computed in Section 21.49.055, Subsection A.
|
|
C. For customers who provide their own transformation from City Light's standard distribution system voltage of 4 kV, 13 kV, or 26 kV to a utilization voltage, a discount for transformer investment will be provided in the amount stated in Section 21.49.055, Subsection A. Existing customers served by City Light's 34.5 kV system as of January 1, 1995 shall be considered as receiving standard distribution voltage for the purpose of this section. This 34.5 kV voltage will not be offered as a standard distribution system voltage for any new customers.
|
|
D. Seattle City Light will provide
one
transformation from the available distribution system voltage of 4 kV or higher to a standard service voltage, and metering normally will be at the service voltage level. However, if the Department determines that it is either uneconomical or impractical to meter at the service voltage level, the Department will meter at the distribution voltage level and will either program the meter to deduct computed transformer looses or will reduce the monthly kWh billed by the amount of the discount for transformer losses.
If the customer elects to receive service from Seattle City Light's available distribution system voltage of 4 kV or higher, metering will be at the distribution voltage level and the discounts for transformer losses, if applicable, and for transformer investment, if applicable, will be applied to the customer's billings. However, if the Department determines that it is either uneconomical or impractical to meter at the distribution voltage level, the Department will meter at the service voltage level and the discount for transformer losses will not be applicable.

POWER FACTOR RATE

SCHEDULE PF
The monthly charge for average monthly power factors below 0.97 shall be as follows:
|
|
0.14¢ per kVarh
|
|
Section 21.49.080
|
|
A. When any inductive load causes unsatisfactory conditions on the Department's system due to induction, the Department may, at its discretion, install reactive kVA-hour meters and make a monthly charge in addition to demand and energy charges whenever electricity delivered to the customer has an average monthly power factor of less than 0.97.
|
|
B. Unless specifically otherwise agreed, the Department shall not be obligated to deliver electricity to the customer at any time at a power factor below 0.85.
|
|
C. The average power factor is determined as follows:
|
|
|
D. The meter for measurement of reactive kVA hours shall be ratcheted to prevent reverse registration.
|
|
E. All installations of power factor corrective equipment shall be subject to the approval of the Department. The customer's corrective equipment shall be switched with the load so that at no time will it supply leading reactive kVAs to the Department's distribution system unless written Department approval is obtained to do so.
|
|
F. This monthly charge may be waived in whole or in part to the extent that the Department determined that a power factor of less than 0.97 would be advantageous to the Department or if the addition of corrective equipment would be detrimental to the operation of the Department's distribution system.
|
|
G. Customers who install new or enlarged arc furnaces shall install static var generators for flicker control and power factor correction for the entire arc furnace load. The generators shall have one-half cycle response time and independent phase control, supply sufficient reactive power to prevent objectionable flicker at the common connection point of the arc furnace with other utility customers, maintain a minimum power factor of 0.97, and be filtered to limit the total harmonic current to no more than the percentage of fundamental current given in "IEEE Recommended Practices and Requirements for Harmonic Control in Electric Power Systems, IEEE-519", latest revision.
