After identification and quantification of saline sources, efforts were directed to highl.ighting opportunities of using saline water in power- ~ plant cooling and industrial processing as well as coal slurry pipelines. ~ The WSCC (Western System Coordinating Council) estimates that about UI 15,500 megawatts 'of ;new coal-fired generat ing capacity wi 11 be installed in ~ or near the Colorado River Basin in the 1981-1990 period. These projec- tions reflect th~ influence of recent energy conservation measures. An additional 17,000 megawatts of coal-fired generating capacity is antici- pated in the Basi'n by the 1990's. I About 42 potential powerplant and synfuel facility sites located in the Basin were screened1for saline water use. Those 42 sites are active as well as dormarit in terms of near term potential development. Water supplies for most have already been identified and some have been obtained. Saline water use 'generally has not been considered because of the addi- tional cost. However, if technical and financial barriers can be overcome, saline water use ,on a large scale could be achieved. The needs for cooling water in the 1980's:for 15,500 megawatts of installed capacity would be about 185,000 acre-feet per year. A similar volume could be used in the 1990's. In view of 't he 610,000 acre-feet per year saline water supply available, a sizable portion of the projected future water requirement for energy development in and near the Basin could be met using saline water. I The study summarizes projected powerplant additions for the Western States and the Colorado ,River Basin to further delineate the need for cooling water. A significa~t shift in the electrical plant generation mix was seen over the next 25 ,years to coal-fired facilities. For purposes of this study, a coal ma~ket scenario was developed which projects the need for about 50 to 100 million tons of coal to be transported to possible future market centers near1the West Coast. This is based on a conservative view of the combination of possible coal uses illustrated in the following table: .
