Fuel Cost Charge is Prorated

The electric charges usage period on your bill typically spans parts of two calendar months according to the billing cycle. The Fuel Cost Charge line item reflects a prorated or blended charge to match this usage period. The amount is based on the number of billed days and the corresponding effective fuel cost charges for each calendar month. For example, a metered customer's bill with usage period from June 15 to July 15, this customer is billed 15 days for June fuel cost charge and 15 days for July fuel cost charge.
