<br />PRODUCTION <br /> <br />Power Potential <br /> <br />Kilowatt-Hours Produced: The amount of power that can be pro- <br />duced by the project is computed allowing an overall efficiency of <br />80 percent (turbines, 85 percent, x generators. 96 percent, x <br />switchin~. 98 percent). Since prices in the project revenue com- <br />putations are based on the customer's receiving power at the Dot- <br />sera Powerplant. no transmission losses are included. The annual <br />kilowatt-hours available for sale are obtained by multiplying the <br />" acre-feet of water annually run through the plants by the average <br />head, the efficiency factor J and the factor 1.025. Head losses are <br />assumed to average those in effect with 60 percent of the maximum <br />flow for the computation of kilowatt-hours. <br /> <br />Powe:I'fllant <br /> <br />Acre - <br />feet <br />annually <br /> <br />Net head <br />after deduc- <br />tion of <br />friction <br />losses <br /> <br />KW.-hours <br />annual pro- <br />duction <br />available for <br />market <br /> <br />Sweetwater plant <br /> <br />115,630 <br /> <br />1,418 <br /> <br />134,118,000 <br /> <br />DotseI'o plant <br /> <br />143,380 <br /> <br />1,468 <br /> <br />172,890,000 <br /> <br />TOTAL . . . <br /> <br />. . . . . . . . . . . . . . . <br /> <br />307,008,000 <br /> <br />Powerplant Capacities: The design capacity of the Sweetwater <br />Powerplant is based on the maximum head when Meadows Res- <br />ervoir is full. This would be 1~490 feet less pipe and penstock <br />friction losses~ or 1,388 feet. Since the capacity is based on the <br /> <br />2114 <br /> <br />generator output~ lOSses in the switching area are not included. <br />The efficiency factor is then 0.85xO.96, or 0.816, ai1d the design <br />capacity is 1,388 (foot head) x 0.816 (efficiency factor) x 260 (cubic <br />feet per second) x .0846 (conversion factor), or 24~ 900 kilowatts. <br /> <br />The installed capacity of Dotsero Powerplant is: 1,384.5 x 0.816 <br />x 330 x 0.0846, or 31,500. The total design capaoity for both <br />powerplants is 56~ 400 kilowatts. The system capa8ity factor is <br />307,000,000 divided by 494,064,000, or 62 percent. <br /> <br />Power factors are based on the ability of a syste.:n. to meet the <br />demands of the market and are often the same as the capacity <br />factor. Where plants feed into a large interconnected transmis- <br />sion system~ as contemplated for the Sweetwater Project~ only <br />the capacity factor is significant in referring to the Sweetwater <br />Projectfs capability. <br /> <br />Water Service Potential <br /> <br />A total of 143~ 380 acre-feet of water would be passed through the <br />Dotsero Powerplant by the project. While all of this water would <br />be clear and suitable for municipal use, some of it must be re- <br />leased to senior downstream rights. The amount available for <br />sale by the project would be all water imported from the White <br />River Basin, all annually placed in storage from the Colorado <br />River Basin, and that water which passes through the Dotsero <br />Powerplant during the spring runoff not belonging to senior appro- <br />priators downstream. The first of these has been det:=rmined, but <br />the last two cannot be determined exactly without a more detailed <br />hydrOlogy study. For the purposes of this preliminary report~ <br />these amOunts of water are estimated by an approximate method <br />as follows: <br /> <br />16 <br />
