<br />.." <br /> <br />(. ~ <br /> <br />The installed capacity having the lowest cost of energy and <br />having a reasonable plant factor for a hydroelectric installation <br />will be selected for the project. <br /> <br />This analysis shall include the following: <br /> <br />a. Obtain preliminary equipment quotations from suppliers <br />of major equipment. <br /> <br />b. Establish unit power values for energy and capacity as <br />described in Task 14. <br /> <br />c. Make a preliminary estimate of the construction cost for <br />each alternative, based on experience cost data for the <br />major project features. Such cost data could Include a <br />combination of current Corps of Engineers, FERC and <br />Contractor's experience data, and will be based on the <br />cost parameters developed in Task 10. <br /> <br />d. Determine annual costs of each alternative. <br /> <br />e. From Task 9, arrive at an annual cost of power from an <br />energy and capacity viewpoint, for each alternative <br />installed capacity. <br /> <br />f. Compare cost of power from each alternative installed <br />capacity to the cost of purchasing the same amount of <br />power using the unIt values in b. above. <br /> <br />g. Compare benefit-cost ratios for each installed capacity <br />to arrive at the selected installed capacity. <br /> <br />Task 16 - Cost Estimate <br /> <br />A detailed construction cost estimate of the selected <br />project arrangement will be made upon completion of the <br />preliminary design. The estimate will be made on the basis of <br />January 1, 1982, cost data. Powerhouse mechanical and electrical <br />equipment costs will be based on manufacturer's quotations, while <br />the civil/structural, substation and transmission features of the <br />project will be based on experience data for prices as applied to <br />unit quantities of construction. <br /> <br />Estimates will also be prepared of the annual cost of <br />project amortization, and of all operatIon and maintenance and <br />replacement costs. <br /> <br />Taski7 - Final Report <br /> <br />A final report will be prepared summarizing all of the <br />work accomplished during the study, including the work reflected <br /> <br />-14- <br />
