<br /> <br />. <br /> <br />CHAPI'ER II <br /> <br />COMPREHENSIVE PLAN <br /> <br />Power Economy and Development <br /> <br />Power market area <br /> <br />The Juniper powerplant would become an integrated part of the Colo- <br />rado River Storage project interconnected system now under construction, <br />The market area for this system will encompass all of the States of Wyo- <br />ming, Utah, Colorado, Arizona, and New Mexico and southern portions of <br />the States of California and Nevada. The low plant factor peaking capac- <br />ity and energy production of the Juniper project would be minor compared <br />with the total capacity and production of the interconnected system and <br />could probably be readily absorbed by the growing loads of the market area, <br />As the power load grows it is expected that the need for low plant factor <br />peaking power capacity in the interconnected system will increase. Fur- <br />ther studies will be re~uired, however, to determine the marketability of <br />project power with power from existing and proposed generation facilities, <br /> <br />Project power development <br /> <br />. <br /> <br />The Juniper powerplant would have an installed capacity of 30,000 <br />kilowatts and a dependable output of about 27,000 kilowatts deliverable <br />to load centers after allowances for a 10-percent transmission loss at <br />peak generationo Under comprehensive development the long-term average <br />annual energy generation would be approximately 96,000,000 kilowatt-hours <br />with about 89,000,000 kilowatt-hours deliverable to load centers after <br />transformation and transmission losses estimated at 7 percent of genera- <br />tion. The maximum and minimum static power heads for the powerplant would <br />be 205 feet and 164 feet, respectively, with a weighted average operating <br />head of about 193 feet. The powerplant would be rated at the minimum static <br />head which is 80 percent of the maximum static head and the dependable gen- <br />erating capability of the plant would therefore be e~ual to its installed <br />capacity. <br /> <br />The maximum water release through the powerplant for full plant capac- <br />ity power output would range from about 2,200 second-feet at maximum head <br />to 2,700 second-feet at minimum head. Under the reservoir operating cri- <br />teria the stream fishery portion of the available water for power produc- <br />tion would provide for about 2,500 kilowatts of generation at a 100-percent <br />plant factor. The additional firm peaking power water releases would pro- <br />vide for about 27.500 kilowatts of peaking operation at a monthly plant fac- <br />tor of about 18 percent. The minimum overall monthly plant factor would be <br />25 percent, while the plant factor would average about 36 percent for <br />energy generation over the long-term period 1922 to 1961, inclUding energy <br />production from advance water releases in' anticipation of reservoir spills <br />in high runoff years as previously explained in the discussion on Juniper <br />Reservoir operationso <br /> <br />. <br /> <br />48 <br />
