Application

This Rider will be applied in conjunction with currently applicable rates.

Billing

The Association's rate schedules subject to this Rider shall be increased or decreased in an amount equal to the kWh used, multiplied by an adjustment computed in accordance with the following formula:

PCA=C/S   -$0.0835      ($0.0055) effective  04/01/2011

                                        ($0.0011) effective 01/01/2012

IPCA= CI/SI - $0.0712  ($0.0055) effective 12/01/2009

                                       ($0.0011) effective  01/01/2012

LPCA = Flow through from power supplier

Where:

PCA=Power Cost Adjustment (applies to all customers with a billing demand less than 1,000 kW.)

IPCA= Industrial Power Cost Adjustment  (applies to all customers with a billing demand equal to or greater than 1,000 kW and not on a market based rate or rate schedule 22.)

LPCA = Large Power Cost Adjustment (applies to customers billed under rate schedule 22A and subsequent versions)

C= Projected Annual Cost of Purchased Power for all rate schedules with a billing demand less than 1,000 kW.

S = Projected Annual kWh Sales for all rate schedules with a billing demand less than 1,000 kW.

CI= Projected cost per kWh purchased for customers with a monthly billing demand equal to or greater than 1,000 kW and not on a market based rate.

SI = Projected annual kWh sales to customers with a monthly billing demand equal to or greater than 1,000 kW and not on a market based rate.

The Power Cost Adjustment for any year will be made on the basis of the projected costs and sales for the year. Actual costs and sales as subsequently accounted for will be used to determine any overage or deficiency in the adjustment applied in the year. Such overage or deficiency will be taken into account by subtracting or adding an appropriate amount to the adjustment as projected for the succeeding year. The Power Cost Adjustment as calculated annually may be adjusted during the year to minimize any overage or deficiency.
