Show Tells Cost of Steam Plant for Copper Co. SALT LAKE, May 15 A steam power plant to develop 40,000 kilowatts, kilo-watts, as planned by the Utah Copper company engineers, is adequate and will cost about ?3,SO0,000, according to testimony given yesterday by L. B. Stlllwell of Stillwell & Putnum, consulting con-sulting engineers of Now York, before the public utilities commission. The evidence given in connection with Uie application of the Utah Power & Light company for an increase in rates on its power system. Esetimatlng Utah coal to bo delivered deliv-ered at the plant at $3 a ton and to havo a heating quality of 13,000 British thermal units, Mr. Stlllwell said that the total operating cost of the plant-to plant-to produce the load required, 37,960 kilowatts kil-owatts maximum, with an average load of 3S.373 kilowatts, would be $823,791 a year. Adding capital costs for interest, depreciation and the like, tho resulting cost of the power to the Utah Copper company would 4.1 mills per kilowatt hour. This gives the annual load factor of 85 per cent. Tho evidence was introduced intro-duced to controvert that of the power company, given earlier In the hearing, which was to the effect that a power .plant on Utah lake, at 45,000 kilowatt capacity and under a 75 per cent load factor, would deliver power to the terminal ter-minal station at Salt Lake at a cost of 10.63 mills per kilowatt hour. Should the annual load factor fail to 50 per cent, the cost per kilowatt hour would run to to 13.S5 per cent, according to the power company's estimates. |
