<br />,!'l r,i"'1 " 6 <br />iJ f,;,~ .d1 <br /> <br />When Flaming Gorge and Glen Canyon dams were constructed in the late <br /> <br /> <br />50's and early 60's and the above preference customers (among others) began <br /> <br /> <br />purchasing power through the Colorado River Storage Project, it was estimated <br /> <br /> <br />at first that the power from these two sources would meet their needs well into <br /> <br /> <br />the 1990's. It became apparent by 1970 that this was not the case and new <br /> <br /> <br />power sources must be found to meet members' needs in the 1980's. <br /> <br />Under leadership of Moon Lake Electric Association, siting studies for <br /> <br /> <br />a steam electric power plant in northeast Utah and western Colorado have been <br /> <br /> <br />conducted over the last 15+ years. Preference right leases to mine coal on <br /> <br /> <br />Bureau of Land Management lands within their service area near Rangely, Colorado, <br /> <br /> <br />were acquired in 1963. In early 1973 oil shale developments in western Colorado <br /> <br /> <br />and northeast Utah were being proposed. Projected power requirements to meet <br /> <br />the oil shale industry needs were in the 200-600 MW range. This prospective <br /> <br /> <br />large power user, however, has not materialized so planning for a greatly reduced <br /> <br />size of plant has now emerged. (1979). Sizing alternative studies to serve only <br /> <br /> <br />projected owner-consumer demands concluded that a 350 MW unit would be required <br /> <br /> <br />in 1985 and a second 350 ~fW unit in 1998. <br /> <br />The site selection study using the following criteria evaluated and <br /> <br /> <br />compared four Utah sites and one Colorado site as follows: (1) Development <br /> <br /> <br />of an adequate long-term water supply, (2) development and delivery of a long-term <br /> <br /> <br />coal supply, (3) environmental constraints, (4) socioeconomic considerations, <br /> <br /> <br />(5) site engineering requirements, and (6) potential bulk power delivery points. <br /> <br />Site No. 3 in Utah (figure 18) was selected as the preferred site. <br /> <br />A potential water supply for the Moon Lake Plant, estimated at 8,000 <br /> <br /> <br />acre-feet annually, is obtainable from White River Reservoir. However, a 30 <br /> <br /> <br />cfs right in Green River has also been acquired by the Cooperative. Water supply <br /> <br /> <br />pipeline routes from the water sources to the plant site are shown in figure 18. <br /> <br /> <br />As can be observed in figure 18, the length of pipeline from Green River to <br /> <br /> <br />site 3 is approximately 17 miles. Timing of White River Reservoir construction <br /> <br /> <br />will apparently determine which water source will be used for Moon Lake Power <br /> <br />Plant demands. <br /> <br />- 33 - <br /> <br />
