(a) Power Cost Adjustment-Rider No.1. The power cost adjustment per kWh, which shall be applied to all kWh units sold under these rate schedules, shall be calculated as a rolling twelve (12) month average, shall be the sum of purchased power supply costs based on data from the most recent twelve-month period preceding the start of the billing month to which the adjustment is to be applied, less an average retail power supply cost of $0.0600 per kWh, which has been incorporated into all retail base rate schedules. Components of the adjustment are hereby adopted for all utility bills issued on and after June 1, 2018, and are calculated as follows:
12 month P/S Cost ($) - $0.0600
12 month P/S units / 1.048
(1) Power supply cost. The power supply cost increment per kWh shall include all costs incurred in the procurement of adequate power supply, transmission of power supply, and adjustments required to reconcile previous over/under PCA collections.
(2) If at any time the power cost adjustment for a month increases by more than fifty percent (50%) over the preceding month, it may be spread equally over two billing periods. The portion to be carried over into the second billing period shall be adjusted by the ratio of the net kWh units of the first month to the net kWh units of the second month.
(b) Primary Metering Discount-Rider No. 2. If the electricity is metered on the primary side of the transformer, a discount of two percent (2%) of the total electric bill, prior to any applicable taxes, in each of the City's electric schedules shall be allowed for electricity so metered.
(c) School Discount--Rider No. 3. For electricity provided to all public schools and property within the City corporation limits and under the jurisdiction of the local Board of Education, a discount of thirteen and seven tenths percent (13.7%) shall be allowed for the total electric billing plus power cost adjustments in each of the City's electric schedules.
