This amount represented more than half of the <br />total amount of energy used within transmission distance of the Hoover <br />plant. And the Hoover plant continues to supply more than half of all <br />energy requirements in its pov,ler-market area. <br />As of June 30, 1947, a grand total of 39,655,519,030 kilowatt.hours of <br />energy have been generated by this giant power plant. <br />The income resulting from the Hoover Dam power plant has risen steadily. <br />In its first fiscal year of operation, 1937-38, the gross income amounted to <br />nearly $3,000,000. Gross annual income reached $4,500,000 during the <br />fiscal year 1939-40. <br />As the number of generating units increased so also did the gross re\'enue_ <br />Gross yearly returns have averaged nearly $8~OOO,OOO since 1943. <br />Since commercial power production began, a grand total of $62,657,725 <br />has been returned to the Treasury of the United States from the sale of <br />energy. After operation and maintenance costs have been deducted the net <br />returned to the Treasury has been approximately $47,000,000. <br />Fourteen high-voltage transmission lines connect the Hoover power plant <br />with its power-market area. Three lines terminate at Los Angeles 266 miles <br />away_ Two lines extend directly to Chino, Calif., a distance of 233 miles, <br />and a third line also extends to Chino via Hayfield, Calif. A seventh line <br />goes to San Bernardino, Calif., while other lines extend to; Kingman, Ariz.; <br />Needles, Calif.; Pioche, Nev.; Las Vegas, Nev.; Boulder City, Nev.; and <br />two lines go to the basic magnesium plant at Henderson, Nev. <br />Parker Dam, on the Colorado River 155 miles below Hoover Dam, has an <br />installed capacity of 120,000 kilowatts. The Parker power plant produces <br />about 750,000,000 kilowatt.hours of energy annually. Transmission lines <br />from Parker Dam supply energy to Phoenix, Yuma. Tucson, and other points <br />in Arizona, and to the Imperial Valley in California. The Hoover and Parker <br />power plants are interconnected to secure maximum benefits from these <br />important plants. <br /> <br />, <br />, I , <br /> - - --- <br /> - <br /> I - <br /> - , <br /> ........~OWER OUT~UT --- <br /> --- <br /> --- <br /> . <br /> - <br /> , <br /> _pow RREVENUE <br /> t-- <br /> , <br /> --- <br /> -- <br />, , <br /> --- <br /> 0 <br /> <br />o <br /> <br />of 1944, four additional generators had been placed in operation, bringing <br />the plant to its present capacity of 1,034,800 kilowatts. <br />Two of the foregoing generators supply energy {or the city of Los Angeles, <br />and two serve the Southern California Edison Co. <br />One of the major users of energy during the late war, was the huge basic <br />magnesium plant. Constructed some 12 miles northwest of Boulder City. <br />by Defense Plant Corporation, this plant, in 1943, consumed one-quarter <br />of the total output of the Hoover power plant. In this plant was produced <br />a substantial portion of the magnesium used in the manufacture of incendiary <br />bombs which ultimately found their targets on the industrial cities of <br />Germany and her allies. <br />As new generators were added, the plant output in terms of kilowatt.hours <br />of energy increased. Under the stress of wartime demands, more than <br /> <br />The ROllliiied Benefits <br /> <br />As the amount of energy generated at Hoover Dam has risen steadily; so <br />also have the benefits ramified into the varied phases of Southwestern <br />economy. <br />A direct result of the Hoover power plant has been the lowering of energy <br />rates throughout the power-market area. Nowhere has this trend been more <br />pronounced than in Las Vegas, Nev. In fact, Las Vegas enjoys one of the <br />lowest energy rates of any American city. Rates in this Nevada city have <br />been reduced from a maximum of 8 cents a kilowatt. hour to 3 cents. And <br />the rate for energy over and above 500 kilowatt-hours is only 5 mills. <br />Likewise lowered energy rates have been the result in Los Angeles. In <br />the first year of operation, it has been estimated that Hoover energy resulted <br /> <br />50 <br /> <br />51 <br />
