<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.
