In the calculations no reserve steam capacity <br /> <br />was contemplated to be used for firming project energy. <br /> <br />Table No.3 in the appendix is a summary of the net energy pro- <br /> <br /> <br />duction of &11 projeot plants. Table No.4 indioates the monthly produc- <br /> <br />tion by each plant for the period 1902 to 1941. Table No.. 5 indicates <br /> <br />the quantity of energy necessary to be supplied during off-peak periods <br /> <br />by steam plants to firm the projeot energy to 720,000,000 kilowatt.hours <br /> <br />per year. It may be noted that there are sixty-seven month_s out of a <br /> <br />total of four hundred and eighty when off- peak S'team energy would have <br /> <br />been required. <br /> <br />The provisions of the oontract between the United States and <br /> <br /> <br />the Northern ColoradO Water Conservancy District (see page 8 of this <br /> <br /> <br />report) would limit the generation of rim energy to about 750.000,000 <br /> <br />kilowatt-hours per annum summarized as followsl <br /> <br />Source <br /> <br />Energy 1,000.000 kwh. <br />per Annum <br /> <br />Tunnel diversions 255,000 A.F. <br />Big ThCllllpson <br />Plant No. t; <br /> <br />583 <br />98 <br />113 <br /> <br />794 <br /> <br />J!!i <br /> <br />750 <br /> <br />Total <br /> <br />Energy required for pumping <br /> <br />Net <br /> <br />The above is on the assumption that water at all times would be available <br /> <br />in amounts of at least 255,000 aore-feet per annum for diversion through <br />
