TVA has both fixed and variable costs that it must recover. Since fuel and purchased power cost can fluctuate significantly with changes in weather and shifts in global supply and demand, TVA recovers these variable costs through a monthly fuel cost adjustment (FCA). The TVA Act assigns rate setting duties to the TVA Board of Directors (Board). The rates approved by the Board include the formula used to calculate the monthly FCA, which represents approximately one-third of the wholesale rate.
