The release restrictions impact the SLCA!IP PRS,and the firm power rate ,in <br />several ways: <br /> <br />1, They make less energy and/or capacity available from GCD at <br />the time(s) it is needed to meet contractual load obligations. <br />Energy must be purchased from other suppliers to assure that <br />SLCA/IP customers receive what they are due. <br /> <br />.'2. Water is required to be released frem GCD at times when load <br />is low, resulting in foregone energy sales, or the sale of <br />energy for considerably less money than could have been <br />'realized ~f ~t were av?ilable at ~ ~ore oppqrtune time. <br /> <br />. 'The actual financial expense associated with the GeES-related releases is <br />the difference between operating expenses with those releases and what <br />operating expenses would be it no special constraints were placed on GCD. <br />This calculation is easier said than done. Dat.a from the actual, real- <br />time releases, incorporating the special studies, is readily available. <br />However, the operating expense which would be incurred without the special <br />releases is only a hypothetical figure. It is necessary to extrapolate, <br />using reasoned assumptions, what would have happened at GCD absent the <br />special studies. <br /> <br />. To determine the "Base Case", i.e.; what expenses would have been without <br />the special releases, Western uses the "peak-shaving" algorithm dev~loped <br />by the Environmental Defense Fund (EDF), with some refinements consistent <br />wi th the Power Resource Studies conducted by the GeES Power Resource <br />Committee, The peak'shaving algorithm follows the actual or projected <br />future firm load, and optimizes resources by utilizing the resource mix to <br />minimize the difference between load and resources for any particular <br />hour. <br /> <br />. Western examines impacts to firm operations only; nonfirm operations are <br />excl uded, <br /> <br />Conclusion: <br /> <br />. Western has concluded that the following affected environmental expenses <br />(both historic and future) are nonreimbursable: <br /> <br />f, GCD EIS <br /> <br />G.
