<br /> <br />SUMMARY <br /> <br />~Electric utility service from central stations came first to the <br />-) Eastern portion of the Great Basin Region when the Salt Lake Power, <br />Light, and Heating Company in April 1881 began operation of its 150- <br />~ horsepower direct-current coal fired steam plant in Salt Lake City. <br />~ The Western portion of the region was served shortly thereafter when <br />~ the Reno Electric Light and Power Company built a small steam plant <br />fired by wood supplemented by coal. By 1965 the growing utility load <br />for the Great Basin Region had reached 994 megawattsl/ (row) with an <br />energy demand of 5,519 gigawatt-hoursl/ (gwh), of which 3,033 gwh were <br />supplied by importation from other regions. Installed capacity in the <br />region for 1965 amounted to 779 row. <br /> <br />1t is expected that by 1980 the Great Basin Region will need 2,850 <br />mw or nearly three times the 1965 capacity, and 16,000 gwh27f energy of <br />which 10,557 gwh will be imported from contiguous regions.- New hydro- <br />elect~ic plants would include units of the Central Utah Project. New <br />thermal-electric generation in the basin would be supplied mainly from <br />fossil-fuel steam-electric plants, supplemented by small amounts from <br />peaking facilities such as diesel and gas turbine in the Western sub- <br />regiohs and pumped storage in the Eastern subregions. . <br /> <br />By the year 2000 the region will have a peak demand of some 10,880 <br />row which is nearly eleven times that of 1965, and the energy use will <br />reach, 61,000 gwh of which about 39,870 gwh will be imported from out- <br />side of the region. New generation in the basin will be furnished <br />mainly by fossil-fuel steam plants supplemented by gas turbine and <br />pumped storage units. <br /> <br />\ <br />,-i' <br />, <br /> <br />The Great Basin Region demand will reach about 27,800 mw by the <br />year f020, or 28 times the capacity supplied in 1965, and the energy <br />load will be about 156,000 gwh of which some 46,000 gwh would come from <br />outside of the region. Most of the new thermal-electric power supply <br />will come from nuclear plants supplemented by geothermal, other steam, <br />pumped storage and gas turbines. <br /> <br />New fossil-fueled and nuclear steaM electric plants to be built in <br />the region will increase the annual consumptive use of water from 6,000 <br />acre teet in 1965 to about 123,000 acre feet in 2020. The land <br />required for thermal power plants will increase from some 250 acres to <br />over 3,300 acres by 2020. In the period between 1965 and 2020 pumped <br />storage plants would need about 1,300.acres mainly for single purpose <br />reservoirs, and transmission line requirements would increase from <br />46,400 acres to about 86,000 acres. <br /> <br />The installation costs of power plants and transmission lines serv- <br />ing the region will increase from about 360 million dollars in the 1965- <br />1980 period to over 4,000 million dollars in the 2000-2020 period. The <br />operat~on, maintenance and replacement annual costs (including fuel) <br />will increase from about 16 million dollars in 1980 to nearly 200 mil- <br />.lion dollars in 2020. These include hydroelectric facility 1965-2020 <br />investment costs totaling about 270 million dollars, and annual opera- <br />tion, maintenance and replacement costs of 5 million dollars in the last <br />time frame. <br /> <br />1/ See: glossary for electric power at the end of this appendix, <br />1/ The'plan developed here is but one of many ways of meeting future <br />loa~s. 11 <br /> <br />
