<br />., ;=' <br /> <br />, <br /> <br />..men the 8~ to 9-mile tunnel length between reservoir and power <br />plant is considered. ~Iith the 14.3 foot tunnel and appropriate <br />indices the tunnel cost was estimated at over 23 million dollars, <br />at mininn.un head would be 16! feet. <br /> <br />",;I.",,,K <br />2! The cost of a 115 kil~"att line from Curecanti to Gunnison, <br />Montrose, and Grand Junction with step-up and steP:':down transforma- <br />tion was estimated at $4,652,000 which is $95 per ~ and represents <br />an energy cost of only .8 mills per kwh. The cost ~f alternate <br />stea;n used for benefit-cost analysis includes transmission and sub- <br />station co sts totalling $60 per kw and was based on two eeparate <br />25,0)0 kw steam plants located at the best points to serve the <br />local lIk'l.rket area. <br /> <br />~ The annual cost of O&M and replacement shown for the dam, <br />tunnel and transmission system should be increased to compensate <br />for the increased construction costs. The O&M and replacement cost <br />for '_he powerplant of 68,000 kilowatts of $201,356 is much too low <br />but is some.mat higher than the $184,500 estimated for the 48,000 <br />kilo',att plant size that can be justified with this type of <br />d ev elo pment . <br /> <br />W Their item 19 under cost comperison gives a vallie of <br />1,551,460 for amortization of $49,880,000 at 2~ percent interest <br />over 50 years. This was computed wrong--a factor of .,l03~)e .oaSaS8 <br />should be used which when used with their cost would give <br />$1,758,670. <br /> <br />2/ This is the annual equi valent of the present worth of sal- <br />vage at the end of 50 years for the co sts shown under Bureau <br />adjustment . <br /> <br />3 <br />
