Okla. Stat. tit. 17, § 17-259

Whenever the Commission approves a purchased power adjustment

clause pursuant to Section 258 of this title, the clause shall apply

to all similar distribution cooperatives affected by such increased

costs. In addition, the Commission shall continually monitor and

oversee the application of the adjustment clauses. The Commission

shall hold a public hearing thereon whenever it deems it necessary,

but no less frequently than once every twelve (12) months. The

Commission shall undertake such other investigation thereof as is

necessary to determine whether:

1. Charges or credits made under the adjustment clauses are

based upon the actual prices paid for purchased power, are properly

computed in accordance with the applicable adjustment clause, and

that portion representing fuel adjustment charges made by an

electric generation cooperative are fair, equitable and properly

computed; or

2. Whether the purchased power adjustment clause should be

amended, suspended or discontinued.

If the Commission finds that the charges or credits are not based

upon the actual prices paid for purchased power, or are not properly

computed in accordance with the applicable adjustment clause, it

shall recompute the charges or credits. Appropriate adjustments

shall then be ordered by the Commission in the amount used in

calculating the power adjustment charge for one (1) or more

succeeding months under the purchased power adjustment clause by the

electric distribution cooperative making the error. The purchased

power adjustment clause may be amended upon a finding of changed

circumstances by the Commission, but shall not be wholly

discontinued or suspended except by order of the Commission after

due notice and hearings for the cooperatives affected have been

rendered.
