17 OK Stat § 17-251 (2021)
2021 Oklahoma Statutes|Title 17. Corporation Commission|§17-251. Change in price of fuels or power - Approval of fuel adjustment clauses - Rules for making determination.

|A. No fuel adjustment clause of any kind shall hereafter be authorized by the Corporation Commission if such clause operates automatically to permit charges, assessments or amendments to existing rate schedules to be made which have not been first approved as provided by Sections 251 through 255 of this title, except as otherwise provided for purchased power adjustments by electric distribution cooperatives in Sections 258 through 262 of this title. |B. If the Commission finds that the changes in the price of fuels required for the generation of electricity by any electric public utility, that the changes in the price of purchased electricity required for distribution by any public utility or changes in the price of purchased gas required for distribution by any gas utility, portends a likely and substantial threat to the ability of the utility to earn a reasonable rate of return, or are likely to cause the utility to have an excessive rate of return, or are likely to substantially impair the ability of the utility to acquire adequate supplies of fuel or gas, the Commission may, after investigation and public hearing, approve suitable fuel adjustment clauses to be superimposed upon the existing rate schedules of the public utility. The Commission shall design the fuel adjustment clause to allow the electric or gas public utility to increase or decrease charges to the consumer according to changes in the cost of fuel, purchased power or purchased gas as compared to the price of such fuels or power as reflected in the base rates.C. In the Commission's design of fuel adjustment clauses, the following rules shall apply:1. For the purpose of determining fuel or gas costs, the price paid for the fuel or gas shall be computed at the actual cost of fuel or gas purchased from nonaffiliated persons, firms and corporations; and the actual cost of the production of fuel owned by the public utility or received from affiliated persons, firms and corporations, and in the case of gas, the fair field price for gas owned by the public utility or received from affiliated persons, firms or corporations;2. The cost of fuel or gas shall be the price paid at the point of delivery into the utility system. In the event the transportation is performed by an affiliated person, firm or corporation as defined in this act which is not subject to the regulatory jurisdiction of the Commission, a regulatory agency of another state having jurisdiction, or the Federal Energy Regulatory Commission or successor agency, the charges made for transportation shall be, if allowed at all, only such as the Commission finds fair, just and reasonable, for purposes of this section. Transportation charges approved by this Commission, a regulatory agency of another state having jurisdiction, or by the Federal Energy Regulatory Commission, or successor agency shall be included for purposes of this section, if allowed by this Commission. The proposed adjustment charge shall not include the cost of transportation beyond its point of delivery into that portion of the utility system regulated by the Corporation Commission unless there is presented to the Commission and it is persuaded by reliable evidence which clearly points to the conclusion that failure to do so will substantially threaten the ability of the utility to earn a reasonable rate of return;3. The amount of electric energy produced by hydroelectric generating plants and purchased by the public utility proposing the adjustment charge shall be deducted from the amount of electric energy to which any fuel cost applies;4. The actual efficiency or heat rate of electric public utilities shall be utilized and line losses shall be considered only if reliable evidence clearly points to the conclusion that failure to do so will substantially threaten the ability of the utility to earn a reasonable rate of return;5. Fuel or gas removed from storage or stockpiles shall be taken into consideration on the basis of the weighted average cost method of inventory accounting; and6. No estimated fuel adjustment shall be allowed.Added by Laws 1977, c. 252, § 2, emerg. eff. June 15, 1977. Amended by Laws 1994, c. 315, § 16, eff. July 1, 1994; Laws 2007, c. 340, § 1, eff.
