<br />Utilities Company and California-Pacific Utilities Company energy
<br />from Hoover power plant at the rate of 5,3 mills per kwhr after
<br />February 1, 1960, and energy from Davis power plant at the rate
<br />of 5.3 mills per kwhr after December 31, 1962, Contracts for the
<br />supply of this energy provide for the generation of the Hoover
<br />power plant energy from water allocated to the District and for
<br />replacing this energy by deliveries to the District through Southern
<br />California Edison Company transmission facilities from generation
<br />by the City of Los Ange]es, Southern California Edison Company
<br />and California Electric Power Company in the ratios of 55, 40 and
<br />[, per cent, respectively, During the operating ,'ear ending May 31,
<br />1961,52,971,464 kwhr were delivered to the District during off-peak
<br />hours to replace a similar amount generated at Hoover power plant
<br />by Citizens Utilities Company and California-Pacific Utilities Com-
<br />pany from water allocated to the District, The City of Los Ange]es,
<br />the Southern California Edison Company and the California E]ec-
<br />tric Power Company are reimbursed for energy so delivered at the
<br />rate of 5,3 mills per kwhI' but are charged for one-half of the cost
<br />(,f the Hoover generatinp: facilities utilized by Citizens Utilities
<br />Company and California-Pacific Utilities Company in the ratio of
<br />55, 40 and 5 per cent respectively, The District is charged for the
<br />uther half of the generating cost. The District's cost amounted to
<br />~27,359,37 for the operating year ending May 31, 1961,

<br />The District's pumping load required a total of 2,104,840,769
<br />Iewhr during the operating year ending May 31, 1961, Hoover power
<br />plant supplied 1,322.302,890 kwhr of this amount out of a total of
<br />3,750,985,232 kwhI' or 90,9 per cent of firm energy availab]e to
<br />Hoover allottees, The Hoover firm energy included 3,740.624,000
<br />kwhr generated at Hoover power plant and 10,361,232 kwhr of in-
<br />terchange energy delivered from the Parker-Davis system, Another
<br />250,847,552 kwhI' of the District's energy requirements were de-
<br />livered from Parker power plant as the District's portion of Parleer
<br />energy making a total of 1,573.150,442 kwhI' of hydro energy de-
<br />I'vered during the operating ,vear or enough to pump approximately
<br />760,000 acre-feet of Colorado River water into and through the
<br />aqueduct, The energy availab]e at Parker power plant from July 1,
<br />I 960, to June 30, 1961. and at Hoover power plant from ,June 1,
<br />I960. to May 31, 1961, is summarized in Table 12,
<br />
<br />The remaining 531,690,327 kwhI' required for the District's
<br />pumping load was electric energy purchased from the Southern
<br />California Edison Company, Since the District's pumping load re-
<br />quired more generating capacity than is presently availab]e to the
<br />District from Hoover and Parker power plants, 146,720,036 kwhr
<br />of this purchased energy were delivered during on-peak hours to
<br />supply this additional generating capacity, The remaining 384,970,-
<br />291 kwhr were delivered during off-peak hours. In addition, the
<br />Southern California Edison Company provided the District with
