FPPPA charges stand for Fuel & Power Purchase Price Adjustment charges, which are a variable portion of the electricity bill that changes monthly depending on the amount of electricity used. The charges are based on the varying prices of fuel or coal, and they are assessed for each unit of power used. The FPPPA charge varies from quarter to quarter, and it is usually incurred by the generating company, which is then passed on to the distribution utility, who in turn recovers it from the end consumers. The FPPPA charge can be positive or negative, and any decrease in monthly electricity usage will help to lower the amount in this component. The FPPPA charge is one of the components of the electricity bill, and it is not a fixed charge.
