(a) The costs used to calculate the amount of power cost equalization for all electric utilities eligible under AS 42.45.100 - 42.45.150 include all allowable costs, except return on equity, used by the commission to determine the revenue requirement for electric utilities subject to rate regulation under AS 42.05. The costs used in determining the power cost equalization per kilowatt-hour shall exclude any other type of assistance that reduces the customer's costs of power on a kilowatt-hour basis and that is provided to the electric utility within 60 days before the commission determines the power cost equalization per kilowatt-hour of the electric utility. In calculating power cost equalization, the commission may not consider validated costs or kilowatt-hour sales associated with a United States Department of Defense facility.
(b) An eligible electric utility is entitled to receive power cost equalization
(1) for sales of power to local community facilities, calculated in the aggregate for each community served by the electric utility, for actual consumption of not more than 70 kilowatt-hours a month for each resident of the community; the number of community residents shall be determined annually by the latest figures of the United States Bureau of the Census or other population data that the Department of Commerce, Community, and Economic Development determines is reliable; and
(2) for actual consumption of not more than 500 kilowatt-hours a month sold to each residential customer.
(c) The amount of power cost equalization provided for each kilowatt-hour under (b) of this section may not exceed 95 percent of the power costs, or the average rate for each eligible kilowatt-hour sold, whichever is less, as determined by the commission. However,
(1) the power costs for which power cost equalization are paid to an electric utility are limited to minimum power costs of more than 12 cents a kilowatt-hour and less than $1 a kilowatt-hour;
(2) each year, the commission shall adjust the power costs for which power cost equalization may be paid to an electric utility based on the weighted average retail residential rate in Anchorage, Fairbanks, and Juneau; however, the commission may not adjust the power costs under this paragraph to reduce the amount below the lower limit set out in (1) of this subsection; and
(3) the power cost equalization for each kilowatt-hour may be determined for a utility without historical kilowatt-hour sales data by using kilowatt-hours generated.
(d) An electric utility whose customers receive power cost equalization under AS 42.45.100 - 42.45.150 shall set out in its tariff the rates without the power cost equalization and the amount of power cost equalization per kilowatt-hour sold. The rate charged to the customer shall be the difference between the two amounts. Power cost equalization paid under AS 42.45.100 - 42.45.150 shall be used to reduce the cost of all power sold to local community facilities, in the aggregate, to the extent of 70 kilowatt-hours per month per resident of the community, and to reduce the cost of the first 500 kilowatt-hours per residential customer per month.
(e) The power cost equalization program shall be administered by the authority based on a determination by the commission under (a) and (c) of this section of power cost equalization per kilowatt-hour for each eligible electric utility.
(f) The authority may not deny an eligible electric utility power cost equalization because complete cost information is not available. The commission shall assist an eligible electric utility that is exempt from rate regulation under AS 42.05 to provide the cost information the commission considers necessary to comply with AS 42.45.100 - 42.45.150. Only power costs that are supportable may be considered in calculating power cost equalization. Each electric utility is responsible for keeping records that provide the information necessary to comply with AS 42.45.100 - 42.45.150 including records of monthly kilowatt-hour sales or generation, monthly fuel balances, fuel purchases, and monthly utility fuel consumption.
(g) The commission shall determine the cost of fuel for each eligible electric utility using the procedure for approving fuel cost rate adjustments of electric utilities subject to rate regulation under AS 42.05.
(h) Each electric utility receiving power cost equalization approved by the commission shall
(1) report monthly to the authority within the time and in the form the authority requires; and
(2) use operational equipment designed to meter individual utility customer power consumption and to determine and record the utility's overall fuel consumption.
(i) The authority shall review the report required under (h) of this section. After review and approval of the report, the authority shall, subject to appropriation, pay to each eligible electric utility an amount equal to the power cost equalization per kilowatt-hour determined under (a) and (c) of this section, multiplied by the number of kilowatt-hours eligible for power cost equalization that were sold during the preceding month to all customers of the utility under (b) of this section. Payment shall be made by the authority within 30 days after receipt from the utility of the report required under (h) of this section. If appropriations that have been made for the purpose by July 1 of a fiscal year are insufficient for payment in full, the amount paid to each electric utility shall be reduced on a pro rata basis. In making the pro rata reductions required by this subsection, the authority may not consider any potential supplemental appropriation until the appropriation has been enacted.
