Fuel Adjustment Factors
Fuel adjustment factors are the fuel charges as calculated according to the Fuel Adjustment Clause. The tables on this page list the fuel charges for Secondary Service, Primary Service, and Transmission Service in cents per kilowatt-hour (kWh).
Please note that Austin Energy uses a fuel adjustment factor averaged on a yearly basis. In case of unforeseen circumstances, it may be necessary to change the adjustment factor during a year.
