<br />CHAPTER III <br /> <br />PLAN FORMULATION <br /> <br />per kWh, which is the current pump back energy rate. This value was <br />based on 25 mills, of which the fuel portion, 22.3 mills, was escalated <br />using the fuel escalation factor for coal of 1.73. <br /> <br />Alternatives <br /> <br />Four alternative forebay sites, including the original Dunham <br />Point site selected in 1978, were identified at the beginning of p1sn <br />formulation as being worthy of study. McPhee Reservoir was considered <br />as a potential afterbay in combination with the Hoppe Point, Dunham <br />Point, Trimble Point, and Campbell Mesa forebay sites; and Plateau Creek <br />was considered as a potential afterbay site in combination with Campbell <br />Mesa, The Alternative Reservoir Sites drawing shown below illustrates <br />each of these potential sites. All of the alternatives except Campbell- <br />Plateau Creek failed the tests of acceptability because they would have <br />caused excessive fluctuation of McPhee Reservoir and would have had <br />significant adverse affects on the fishery, recreation, scenery, and <br />operation of the reservoir, Fluctuation control structures were exam- <br />ined but failed the test of completeness because of serious engineering <br />problems and the test of efficiency because of high estimated costs. <br />Consequently, the Campbell-Plateau Creek Alternative remained the only <br />viable configuration, and efforts were concentrated on determining the <br />appropriate powerplant size for this plan. <br /> <br />-----(~ _.- .:::-...... <br />, <br /> <br />Dolores Pumped -Storage Unit <br />--- -~ ~~.-~....,.......~:~ <br /> <br />~ <br /> <br /> <br />".~i, <br /> <br />/'-;; <br />________--=--:::::::::::---- "-.."";~:'::-~->-- ...;,J'i Campbell (Foreboy) ,"I{rw.\)~ <br />. --- }-:~{ I <br />___~ r-_......., I~ -""""'"l., <br />______ ,- -~:-- I OUn~rebaJ) -~i(* /~~'., _~_ll\" ,>1f:"_-~ <br /> <br />Hoppe Point~{For'boy)/ ~-..- ;,_"-&.-'?: ~,_;f;.;,:..-:-' _, ~''''':,~~_ -_J~- Pd~~:ku <br />~.. .~"_'. ;./ . /' . ~:'.;..'.'.'~ .:.::';~~~.~'~.f-(A""b"l <br />~-=-... :' ".", -~~w.:._''of:'.4rimblePo,nt .~\ __ .=:-- <br />-;. 0',' " ~{ , ,~.~t' Fore~ ,_'" __ _~ 7__ <br />. :;$f''- .~;.- '. ~;,"~,\~1 / ", ,,,":;-".iJ;: , _/ <br />.-.<1",... .R;,.~,...Oi:.,.\',.!I., ...
