Summary Report - Central Arizona Project with Federal Prepayment Power Arrangements

Summary Report, Central Arizona Project with Federal Prepayment Power Arrangements, February 1967, page 13early years. Following 1990, it is expected that commercial power sales would increase gradually as project water supply and associated project pumping power requirements decrease. By the year 2030 it is estimated that commercial sales would average 179,000 kilowatts. For purposes of deriving power prepayment cost estimates, it was assumed that a large, coal-fired powerplant would be located near Page, Arizona, adjacent to Lake Powell. Such a plant would burn coal obtained from the Black Mesa fields in northeastern Arizona. Sufficient transmission costs were included in the estimates to provide for proper connection of the plant to the integrated system. Even thought the central Arizona area would be the large commercial load area closest to the powerplant, the commercial power production of the plant would not necessarily serve this area alone. The power output of the thermal plant could be integrated with the power production of Reclamation's interconnected hydroelectric power system which extends generally throught the West. Such coordination could enhance and broaden the usability of the power produced by both the thermal plant and the hydroplants. The coordinated output of these plants could be available to serve loads from Reclamation's interconnected transmission system. Water Salvage Measures Included in this plan are water salvage measures consisting of ground-water recovery in the Yuma area and phreatophyte clearing along the Lower Colorado River. These undertakings would yield 14Epson Perfection 4870 Photo, 400 dpi, 8 bit, 832,779 byte
