Chapter IV develops the future need for additional de- <br />pendable electric utili to' generating capacity for the years 1960, <br />1965, 1970, and 1975 in the Power Market Region. The selected Market <br />Region includes the entire AIIR basin and adjoining areas in I~hich the. <br />potential ~droelectric power could be marketed (plate 1). It com. ' <br />prises about 554,000 square miles or nearly twice the area within the' <br />physical boundaries of the three river basins. The nmximum use of <br />electricity, expressed in terms of kilo\\'att demand at time of peak loa <br />was 6,319,000 kilowatts in 1952. By 1975 the peak load is expected to, <br />increase to 17,819,000 kilowatts or 2.8 times the amount in 1952 <br />(table 12). Dependable capacity available to supply the 1952 loads <br />amounted to 7,370,200 kilowatts, of which 536,500 kilowatts was nydro- <br />electric capacity. After taking into account 3,700,000 kilowatts of <br />fuel-electric capacity and 339,000 kilowatts of ~droelectric capacity <br />already scheduled for installation, and after making allollance for <br />estimated future retirements and for reserves, it is estimated that <br />there will be a need for additional dependable capacity amounting to <br />1,063,000 kilowatts by 1960 and 11,007,000 kilowatts by 1975. <br /> <br />6. I~rdroelectric power that is planned for development at <br />proposed multiple-purpose projects in the MIR Basin m~ be used to <br />supply part of these capacity deficiencies. The type of capacity, <br />hydroelectric or fuel-electric, that cou1d supply tho future loads is <br />determined in chapter VI for each of the eight subdivisions of the <br />Market Region. ' , <br /> <br />Chapter V - Projects Existing and Under Construction for <br />, Hydroo1ectric Power Generation and TransQission <br /> <br />7. This chapter presents pertinent detail on the power <br />aspects and the physical features of the larger ~droelectric proj- <br />ects existing and under construction in the AWR Basins. The ,projects <br />have been categorically grouped as to ownership and are described <br />, under the sub-titles of private, Federal, and other public ownerso <br />Brief infoI'1nation is given on the output and capability of the plants, <br />and of the transmission and marketing of power from the projects. Of <br />the total of 2G plants existing and under construction in the three <br />basins, eight are Federally owned (including two WIder construction), <br />thirteen are privately Olmed, and five are municipally or publicly <br />owned. The total initial installation of the plants is 755,000 ldl- <br />O1fatts and, the annual generation is 2,730 million kilmratt.hours.''- <br />These and other pertinent hydroelectric data are presented in detail <br />in table 2. <br /> <br />2 <br />
