This rider is applicable to and becomes a part of all the Cooperative’s Rate Schedules and Riders, which provide for the supply of metered electric service.
The Cooperative reserves the right to implement a Wholesale Power Cost Adjustment charge at such time as the average cost of purchase power to the Cooperative deviates by 0.001 cents per kWh from the base cost of purchased power used in the design of the Cooperative’s retail Rate Schedules. The Wholesale Power Cost Adjustment (WPCA) will be applicable to all kWh billed under the Cooperative’s retail Rate Schedules and will be calculated as follows:
WPCA = C – B x P + D
C = Actual purchased power costs for the most recent 6 months available plus the projected purchased power costs for the six months immediately thereafter.
B = Base cost of purchased power (6.993¢ / kWh) built into the retail rates.
P = Actual kWh purchases for the most recent 6 months available plus the projected kWh purchases for the six months immediately thereafter.
D = The total accumulated difference between the Cooperative’s WPCA charges and the purchased power posts applicable to this clause through the end of the most recent month available.
S = Actual kWh sold for the most recent 6 months available plus the projected kWh sold for the six months immediately thereafter.
