(A) Applicability. The power supply cost adjustment set forth in this section shall be applied to the total kwh billed to city’s electric consumers for the meter reading period that city determines as most nearly corresponding to the meter reading periods set forth in city’s purchased power billings from its suppliers.
(B) Billed energy and demand charges. The billed energy and demand charges set forth in city’s electric rate schedules are those charges associated with recovery of city’s power supply cost as set forth in division (C).
(C) Power supply cost. The city’s power supply cost is the cost of the city’s power supply requirements as furnished by city’s wholesale power suppliers plus fuel costs associated with energy provided by the city’s generating facilities.
(D) Power supply cost recovery margin. The power supply cost recovery margin shall be the difference between the monthly billed energy and demand charges and the monthly power supply cost. The current target power supply cost recovery margin is 2% and may be adjusted from time to time to achieve and maintain adequate power supply cost recovery.
(E) Monthly determination of power supply cost adjustment (PCA). Each month the city’s billing PCA shall be determined as follows:
(1) The monthly total customer billed kWh, energy and demand charges and total power supply cost for the current month’s billing shall be entered into the appropriate columns of the PCA worksheet.
(2) The monthly target power supply cost recovery margin of 2% shall be entered into the appropriate column of the PCA worksheet.
(3) The PCA worksheet for the current billing month shall calculate the billing PCA as follows:
(a) Power supply cost recovery margin (in dollars) shall equal the monthly total billed energy and demand charges (in dollars) less the monthly total power supply cost (in dollars).
(b) Target power supply cost recovery margin (dollars) shall equal the monthly total power supply cost (dollars) multiplied by the target power supply cost recovery margin (%).
(c) Target power supply cost recovery excess or shortfall (dollars) shall equal the monthly actual power supply cost recovery margin (dollars) less the monthly target power supply cost recovery margin (dollars).
(d) PCA for the billing month shall equal the negative fo the three-month rolling average of the target power supply cost recovery excess or shortfall divided by the three-month rolling average of total KWH billed.
