In recent years the cost of fuel to operate power plants for electric utilities has increased much faster than many utility executives and regulators have anticipated. In the presence of substantial regulatory lag in adjusting rates, stockholders have had to absorb the difference between revenues and unanticipated increases in fuel expenses. In an effort to shorten the time required for increased costs to be reflected in increased prices to consumers, many firms have been allowed to use an automatic fuel adjustment clause (FAC) to pass on increased costs to consumers as they occur. The FAC usually allows the firm to adjust the price of electricity when the price of fuel deviates from some fixed base price. Presently more than 40 of the 50 state regulatory commissions allow some type of FAC.
