Answer -- 258,450 kilowatts and 1,849,570,000 KWH annually at the pumps (or about 287,000 KW and 2,050,000,000 KWH annually at the generating plants). 2. (a) How much power will be developed at Marble Canyon under Arizona's plan? Answer -- 510,000 KW installed capacity (nameplate) and average annual generation at load centers of 2,374,000,000 KWH. 2. (b) How much will be developed at Marble Canyon under the Bureau's plan? Answer (1) For 700,000 KW plant at Marble Canyon the average annual generation, at site, would be 2,580,000,000 KWH, or 2,373,600,000 KWH at load centers. Answer (2) For the Marble-Kanab Tunnel plan 2,530,000 KW and 7,698,000,000 KWH at site, or 2,280,000 KW and 7,082,160,000 KWH at load centers. 3. Assuming no Bridge Canyon Dam is built, how much power would be left for sale after providing for pump lift if a plant is installed at Marble Canyon only? Answer -- The Marble Canyon plant, with 700,000 KW installed capacity, is not financially feasible if operated as the primary energy source for pumping. 4. How much power would be left for commercial sale after providing for pump lift if only a High Bridge Canyon Dam is constructed? Answer -- 3,550,195,000 KWH. 5. How much power would be left for commercial sale after providing for pump lift if only a Low Bridge Canyon Dam is constructed? Answer -- A Low Bridge Canyon Dam that would keep water out of both the Grand Canyon National Park and the Grand Canyon National Monument is not financially feasible.Epson Perfection 4870 Photo, 400 dpi, 8 bit, byte
