1. (a) A regulated participating electric utility shall request a change in its power cost equalization per kilowatt-hour in conjunction with a request for

   1. (1) approval of tariff filing under 3 AAC 52.501 - 3 AAC 52.519; or
   2. (2) a permanent or interim rate change that establishes higher or lower nonfuel costs for the utility.

2. (b) A nonregulated participating electric utility shall request, in accordance with 3 AAC 48.095, a change in its power cost equalization per kilowatt-hour if the utility has

   1. (1) experienced a change in its fuel or purchased power costs; or
   2. (2) changed its rates.

3. (c) The commission will, in its discretion, adjust the power cost equalization per kilowatt-hour of a participating electric utility based on

   2. (2) a review of the annual filing submitted by the utility;
   3. (3) any other evidence that the power cost equalization per kilowatt-hour of the utility is not just and reasonable; or
   4. (4) a determination by the Alaska Energy Authority that appropriations are insufficient to finance full payments to eligible electric utilities, in which case the power cost equalization per kilowatt-hour of each participating utility will be reduced by an equal percentage.

4. (d) A regulated participating electric utility shall submit in support of each request for adjustment of its power cost equalization per kilowatt-hour

   1. (1) a tariff advice letter under 3 AAC 48.270;
   2. (2) tariff sheets that show the amount of power cost equalization per eligible kilowatt-hour requested;
   3. (3) a schedule showing the computation of the requested power cost equalization per kilowatt-hour for each rate schedule;
   4. (4) a summary of the data necessary for determination of the power cost equalization per kilowatt-hour; and
   5. (5) documentation of all data submitted under (4) of this subsection, except that in the case of a request for an adjustment of power cost equalization per kilowatt-hour that is in conjunction with a request for a fuel surcharge rate change, the utility shall rely on the nonfuel costs per kilowatt-hour established in its most recent general rate case.

5. (e) A nonregulated participating electric utility shall submit in support of each request for an adjustment of its power cost equalization level

   1. (1) a written statement of the power cost equalization per kilowatt-hour requested and the name of the person responsible for providing information in support of the request;
   2. (2) a copy or summary of all effective rate schedules for each customer class, stating the current charges without power cost equalization;
   3. (3) a schedule showing the computation of the power cost equalization per kilowatt-hour for each rate schedule;
   4. (4) a summary of all data necessary for determination of power cost equalization per kilowatt-hour; and
   5. (5) documentation, including a copy of the most recent fuel bill, of all data submitted under (4) of this subsection, except that in the case of a request for an adjustment of power cost equalization per kilowatt-hour that is in conjunction with a change in fuel or purchased power costs only, the utility shall rely on the nonfuel power costs per kilowatt-hour established in the approval of its most recent power cost equalization change.

6. (f) A participating electric utility shall file with the commission a periodic fuel or purchased power cost report as follows:

   1. (1) for a regulated participating electric utility, the report required by this subsection is the tariff filing required under 3 AAC 52.501 - 3 AAC 52.519;

   2.
