<br />environmental considerations on the fluctuations as to the effect on <br />that fluctuation on the biological life in there and the sunlight <br />coming through four feet and all that? <br /> <br />MR. KREGGER: There are tremendous problems associated with that <br />operation. We have constructed a model of the pump back storage ope~a- <br />tion. And principally what this model does is, through the use of dyes, I <br />in successive pump back and generating cycles, different colors of <br />dyes show the movement of the water along the floor of Twin Lakes and_ <br />to compute the velocities to make sure that we are not going to <br />disturb this glacial flower that there is about four foot of it, I <br />guess, on0 the floor of Twin Lakes. It goes into suspension with very, <br />very little turbulence and it stays in suspension for quite some time. <br />But according to our model studies, we are not go~ng to turn the lake <br />green. There is some concern about pumping .fish back thrOl,lgh the <br />pumping cycle. We have designed a tail race channel, which we.feel will <br />minimize or eliminate the pumping of lake trout, for example, back <br />through the pump back cycle. We have had ongoing studies now for <br />several years and we plan to continue and have a continuing program <br />which will last on through the first couple of years of operation of <br />the power plant. <br /> <br />MR. FISCHER: What's the total lift and why do you go to separate <br />pumps instead of turbines? <br /> <br />MR. KREGGER: We don't have separate pumps. . We have turbines. <br /> <br />MR. FISCHER: Oh, i'm sorry. I thQught that your discussion was that <br />the pumps are Westi~house and the turbines are Allis-Chalmers, etc., <br />etc. Excuse me. . <br /> <br />MR. KREGGER: I made a .mistake , Rolly.. I don 't want to confuse peopJ,.e, <br />not only with my mistakes, but with the technicalities of this thing. <br />But the pump turbines are a unit which will pump on the pump back cycle <br />and act as a turbine on the generating cycle. The motor generator is <br />Westinghouse. <br /> <br />MR. FISCHER: Thank you. <br /> <br />MR. KREGGER: And, of course, it will generate during the.generating <br />cycle, and it will furnish the power or it will drive the pump during <br />the pump back cycle. <br /> <br />MR. FISHER: Where do you get that power to pump back up? <br /> <br />MR. KREGGER: That I s going to come from the customer. In other words, I <br />when we write a power marketing contract, we will write it with a <br />customer who has o~f peak power available - fossil fuel generated po~er <br />that is on the line, not being utilized. They will pump back dur~ng . <br />the off peak periods and generate during peak periods. <br /> <br />MR. FISCHER: Thank you. <br /> <br />MR. STAPLETON: Does anybody else have a non-technical question? (Laughter) <br /> <br />-lO- <br />
