<br />JJ:;JV <br /> <br />Reservoir. Now the scheme has been modified <br />to the extent that we have one power plant at <br />Elbert and one power plant at otero, on the <br />north shore of Clear Creek Reservoir. <br /> <br />The original installed capacity of the I <br />seven plants was 123,900 kilowatts. The pro- . <br />posed installed capacity of the two plants <br />nm'l in the plans is 111,000 kilm'latts, a minor <br />reduction but still essentially the same gen- <br />eration capacity as proposed in the original <br />plans. There is a real significant difference <br />in this power system; that difference being a <br />change in type of generation. The old original <br />plan with seven plants was essentially a base- <br />load plan, continuous operation and providing <br />a reasonably high load factor in selling <br />kilowatt hours to the customers. The new <br />scheme provides for a modified operation which <br />includes the technique of pump-back storage. <br />By pump-bad. storage I mean that you end up <br />by generating for a relatively short period <br />during the day during the five days in the <br />week when you have peak demands for energy <br />in the late afternoon and early evening. <br />This means that this forebay at the head of <br />this.penstock serves a real vital purpose in <br />that it collects water, which is coming down <br />through the canal during 18 hours of the day, <br />we'll say. This stored water is then released <br />through the penstock and power plant during <br />the peak period of sb: hours \'lhen that addi- <br />tional generating capacity can be ma~.eted <br />at premium rates. <br /> <br />One of our big problems was that we <br />didn't have enough water coming down through <br />our project system. The project imported <br />waters and additional flows that we could pick I <br />up out of the Arkansas, and existing flows <br />coming out of the C.F.& I. Steel Corporation <br />storage were not sufficient to provide for the <br />total operation of the Elbert Power Plant <br />which is nO"l being designed for 100,000 kilo- <br />watts of capacity. We didn't have enough <br />project water and other direct flows to operate <br />
