<br />A-19 <br /> <br /> <br />. <br /> <br />I', "':,' ,"~' ~\ <br />v'-o,', '-..' <br /> <br />The recurrent operation of the Mt, Elbert Pumped-Storage <br /> <br />Powerplant for pecldng power production and pumping will cause <br /> <br />daily fluctuations in Twin Lakes a.'1d the Mt. Elbert Forebay. <br /> <br />The most pronounced water level changes due to powerplant <br /> <br />operations will occur when Twin Lakes and the Mt. Elbert Fore- <br /> <br />bay are near the minimum storage level where their capacity <br /> <br />per foot of water level is lowest. <br /> <br />Powerload curves show that summer peaks are long and flat <br /> <br />being caused mainly by air conditioning and winter peaks are <br /> <br />. <br /> <br />sharper in nature and shorter being caused mainly by lighting. <br /> <br />It is expected that the summer peaks will require about 8 hours- <br /> <br />a-day powerplant operation and winter peaks about 6 hours-a- <br /> <br />day operation, Power demands are lower in the spring and fall <br /> <br />and will probably require only about l\ hours-a-day operation. <br /> <br />It is expected that powerplant operation will average about <br /> <br />6 hours daily, Monday through Friday. Weekend operation of <br /> <br />the powerplant for power production is not planned as pOlo/er <br /> <br />demands fall off on the weekend. <br /> <br />With 6-hour powerplant operation and the average Mt. Elbert <br /> <br />Canal flow of 275 c.f.s" a daily fluctuation of 5.5 feet is <br /> <br />expected in the Mt. Elbert Forebay with one generating unit <br /> <br />. <br /> <br />operating. This will I'esult in a daily fluctuation of fI'om <br /> <br />. <br />
