<br />18 <br /> <br />COLO,RADO RIVER 8TORAGE PROJECT <br /> <br />determined for each subsequent 10-year period to be the average <br />annual generation for each period wIthin the monthly load pattern <br />estimated by the Federal Power Commission, Data from the study <br />indicate that the installed capacity of 1,228,000 kilowatts is required <br />in the initial de(lades to market power and energy at the estimated <br />load factor for tile market area of the study. When stream depletions <br />increase in later :years, project power could be marketed at lowerload <br />factors than the area load factor. Marketing the power initially at <br />the load factor for the area and later at lowerload factors will result in <br />utilizing the project plants most effectively to supply the requirements <br />of the area when operated in conjunction with other power systems, <br />Preliminary data from the power market survey indicate that <br />project-produce4. power and en~rgy Cl>n be readily, absorbed in the <br />market area as 'It becomes avaIlable from the project powerplants. <br />The estimated requirement by 1970 for 3,659,00,0 kilowatts of new <br />generating capa~ity and 14,313 million kilowatt-hours of generation <br />can only be par~ially satisfied by the 1,109,000 kilowatts of capacity <br />and 6,850 millio):\ kilowatt-hours of energy deliverable to load centers <br />from the author/zed units of the Colorado River storage project and <br />, the central Utali participating project. ' <br /> <br />POWER RATES <br /> <br />As shown in the preliminary repayment study on page 48, an average <br />rate of 6 mills per kilowatt-hour for firm ,energy and 2,5 mills per <br />kilowatt-hour fQr nonfirm energy will provide sufficient revenues to <br />repay all reimbl~sable power costs and additional rcvenues to assist in <br />repayment of irr gation costs as required by the authorizing legislation. <br />Definite rate sc edules for firm and nonfirm power and energy will be <br />,developed in a4cordance with departmental policy and marketing <br />,criteria when cqsts are more firmly established and a need for such <br />schedules exists.! <br /> <br />SUMMARY OF PJ;\OCEDURES FOR ECONOMIC AND FINANCIAL ANALYSIS <br /> <br />Procedures adopted for the economic and financial analysis of the <br />'Colorado Riverj storage project and participating projects are con- <br />sistent with present policies of the Bureau of Reclamation and with <br />the provisions o~ the project authorizing act of April 11, 1956. Salient <br />information con'cerning the procedures is listed below. <br />(1) Analyses }vere made of the storage project units and, partici- <br />pating projects In the followin~ combinations: ' <br />(a) The ~our storage umts were analyzed separately and jointly <br />for benefit-cost comparisons and jointly for cost allocations and <br />repayment,. <br />(b) The ill participating projects were each analyzed sep- <br />arately. : <br />(e) The <I storage units and 11 participating projects were <br />analyzed jointly to show ths overall expenditure and repayment <br />reqUIrements, <br />(2) Construc~ion cost estimates are the latest official estimates of <br />the Bureau of R~clamation and cooperating agencies and are based on <br />the January 19r7 price level except that bid prices are used where <br />
