The Power Cost Adjustment is a factor applied to cover fluctuations in the charge the Cooperative incurs from its wholesale power supplier. Rather than adjust the energy charges frequently, this factor allows the Cooperative to maintain a constant energy charge while recovering the actual cost of purchasing power to supply to the membership. When the cost of purchased power is above the base cost, the customer is charged a corresponding amount in the form of a power cost adjustment. When the purchased power is below the base cost a credit is applied to the customer's monthly bill.
