Show WATER FOR UTAH . . . Utah's Potential Power Requirements... The sum total of all these potential power requirements for domestic, commercial/ rural and industrial purposes to be met by utilities in Utah reaches a total of approximately 6 billion kilowatt hours, approximately a fivefold increase by 1970. This amount is on the order of Hoover Dam's annual production. ( See Chart 11 - Energy Requirements by Class Use-- page 92.) This estimate is reasonable if if is realized that it will parallel the State's desirable growth. Utah's strategic place of importance in the pattern of national and western expansion can only be maintained if its power resources are abundantly developed. Its unexcelled supplies of agricultural lands and industrial raw materials furnish a base which can provide major- scale wealth and security for the State and the Nation. The keystone, however, is in plentiful water and power supplies; as part of the water supply program, the generation of electric power transmitted to consuming centers, is an imperative " must". ,.. Utah's Power Generation ... In 1947, there were 55 hydroelectric power plants in Utah, with a total installed capacity of 92,445 kilowatts, which produced during that year a total of 366,186,000 kilowatt- hours. In addition, there were 29 internal combusion generating plants and 4 steam electric plants having a combined capacity of 14,099 kilowatts and 68,- 750 kilowatts, respectively; together these produced 26,292,000 and 169,720,000 kilowatt- hours, respectively. ( See Chart 12 - Past State Power Requirements •- page 95.) In other words, of the total installed capacity in the State in 1947, 52.9% was in hydro plants, 20.8% represented steam plants and 8.0% was for internal combusion. This compares with the national average of 28.7%, 68.8% and 2.5%, respectively. As to generated energy, the distribution in Utah was 65.1 % for hydro, 30.3% for steam and 4.6% for internal combustion. The national average for the same year was 30.7%, 68.2% and 1.1%, respectively. This demonstrates the superior place of hydroelectric power in total power facilities of the State. i ', ' J" QXO '*> i* rc o. b* JO •>- , iji « - i? • >*^ •••.'' iwo ' noillim bsibnuri These data, however, refer only to the utility systems of the State. In addition, major industrial plants provided their own power supplies although some were interconnected with utility systems for dependability and to provide excess energy not consumed within industrial operations. For example, in 1944, the Geneva Steel Company and the Kennecott Copper Corporation each placed a 50,000 kilowatt steam- electric plant into operation. Since then, the Kennecott Copper Corporation has added another 50,000 kilowatt to its existing plant. As noted, part of the industrial power capacity of the Geneva Steel Company has been available to the power system of the Utah Power and Light Company. The three most important privately owned utilities in Utah are the Utah Power and Light Company, Southern Utah Power Company and the Telluride Power Company. These provide over 90% of the total utility- assured capacity of the State. The remainder is in publicly owned power plants representing primarily small municipal operations. The privately owned utility power plants, for the most part, are interconnected, but it must be admitted that the transmission systems are characterized by low capacity and low voltages. In order to provide for interconnections with hydroelectric plants in southeastern Idaho and Montana, a major part of the transmission system is heaviest north of Salt Lake City. It must be observed that, as in the case of generation, transmission and interconnection are inadequate for the rapid development of Utah's future power requirements. ( See Map 21 - Existing Electric Utility System - page 97.) As a matter of fact, they are strained to capacity to meet present requirements. This is recognized by the announced plans for some expansion by local private utilities. However, future needs of the State will demand a completely different although supplemental pattern of both transmission and interconnections.
