Show DISCUSSION OF DR. PLUMB'S ADDRESS Toastmaster ( A* B » Young): That you may comprehend that the cost of power described by Dr. Plumb is extremely cheap when the necessity of transmitting it over long distances is eliminated, the chaii* wishes to state that an industry consuming somewhere around 2000 to 4- 000 H. P, has to pay for that power at present at slightly over 8 mills per kilowatt hour of consumed energy. The basic price for power for electrolytic purposes in Montana is $ 25.00 per H. P, year as against the $ 27,00 to $ 30.00 estimated by Dr. Plumb, This figure for Montana power is correct, is it not Mr. Elton? Mr, Elton: Yes, Toastmaster: I might say that for the conditions outlined by Dr* Plumb, that is, a 100,000 kilowatt demand with 75,000 kilowatt average load, under the best rates now obtainable the cost of power per kilowatt hour would be somewhere between 6 and 6- 1/ 2 mills, or slightly over $ 40* 00 per H, P. year on energy consumed.
