1981 and 1982 due to the Central Utah Project. Other than these.in- creases, the general trend in dependable capacity is downward after 1975 due to the anticipated upstream water depletions by the participating projects. - d. Power marketing criteria. The original power marketing criteria established in 1962. that CRSP power would be sold by summer and winter seasons to customers located in the market area, as described in Subparagraph D(l), with priority being given to preference customers and with the provision that, as loads develop, power could be withdrawn from the Southern Division for sale in the Northern Division until the loads in the Southern Division are reduced to 20 percent of the project capa- bility in the summer season and 7 percent in the winter season. Allo- cations of power were made, based on the applications received and the CRSP generating capacity installed. Sales to customers with no supple- mental supply are permitted by existing contracts to meet their total requirements until April 1976, regardless of load factor. Sales to customers with supplemental supply are generally permitted up to about 70 percent load factor until April 1976. From April 1976 through fiscal year 1986, the maximum seasonal load factor permitted will be 58.2 percent for all customers. This change in marketing policy is planned because, as the CRSP generation decreases due to increased water depletions, the need for purchases of firming energy increases, and the price of such energy is constantly increasing. Therefore, consistent with sound business principles, the amount of energy purchases should be decreased to improve the financial feasibility of the project. In addition to limiting project sales under existing contracts after March 1976 to 58.2 percent load factor per season, it has also been decided to market the power from future CRSP powerplant additions as peaking power, i.e., sales of capacity without energy or with return of energy. Also, at any time the CRSP saleable capacity exceeds the present capacity contracted for, the excess capacity will be sold without energy or with return of energy. After expiration of the existing contracts, most of which will expire in 1986, it has been assumed that new contractual arrangements can be made such that the firm energy and capacity sales will be equal to the gener- ation available less transmission losses. 5. Expenses. Annual expenses of operating the CRSP power system are shown in the repayment study (Table F-l). The several categories of expenses are discussed below. a. Operation and maintenance costs. The operation and main- tenance costs of the project have been increasing steadily since the project operation started in fiscal year 1964, due to increases in the costs of labor, supplies, and maintenance parts. Much of the movable equipment, which is included as an O&M cost, is nearing the end of its 32
