Show II UTAH LifT AND POWER COMPANY I 1q The system now owned and operated re by the Utah Light and Power company dt com-pany comprises three waterpower plants enghty miles of highpension transmission JInes and also light and t power distribution apparatus In and near Salt Lake City and Ogden together I 1 to-gether with one substation for supplyIng V y supply-Ing the Salt Lake City railroad md I some reserve steam plants Probably no other city of Its size In the United t States has electrically transmitted f power reached such a relatively Important R Import-ant place In the community as at Salt Lake City The development not only gr started early but has been very rapid tl The snowfed mountain streams of the Wnsatch range to the fast of Salt Lale t vrJloy offered opportunities to the hydraulic hy-draulic and electrical engineer which i have not been neglected To understand under-stand the situation a short historical It review will be necessary Although coal is not excessively high being from 250 a ton for slack to 150 for best lump 1 the proximity of waterpower with high wood canyon for transmitting power for the Salt Lake City railroad The first two of these plants finally became consolidated with the electric lighting Interests of Salt Lake City and are now operated together with the third plant us parts of one complete and comprehensive com-prehensive system covering a district extending north and south about sixty miles Including Ogden Salt Lake City and a district thirteen miles south of the latter place Including some large smelters The accompanying map shows the district covered and the lines I and powerhouses The Ogden powerhouse has an electrical elec-trical Installation of 5000 horsepower ai present The company Is now about to commence com-mence the construotlon of a large dam In the Ogden carryon which will forma form-a storage reservoir for the flood waters The reservoir so constructed will have a total capacity of about 2000000000 cubic feet of water and will be used for both Irrigating and power purposes When this reservoir Is constructed the Ogden powerhouse will have a maximum maxi-mum capacity of 8500 horsepower The plant will then be completed as It was 1 I 1 Ii F a I k I f r I 5 I I tlt 0 9d I I G Ogden I A r I tL i ti Weber vrA t u I Ii d t o r La s o Fr rn n bn 1 J c r e ai = So La e 1 i Ur 1 I J I J I I

reliable under all the I varylnc conditions that hMO been < r t found to occur in the Cottonwood canyon can-yon The power is being transmitted from Ogden at 16000 volts and from the Cottonwood Cot-tonwood canyon at 12000 volts Certain Cer-tain changes are now being carried out and when these are completed the whole transmission system will be operated ope-rated at 25000 volts These improvements Improve-ments will reduce losses to a minimum and will enable the company to obtain not only greater efficiency from all the plants but also to give a much more reliable service under all conditions In Salt Lake City the company have now three reserve steam plants of an aggregate capacity of 2000 horsepower These plants are used in case of emergency emer-gency and to supply any shortage of power caused by a breakdown or other accident at the powerhouses In the I canyons The companys engineers are now designing = de-signing an entirely new station to be built in the west end of the city This station Is eventually to replacethe sevi oral substations and anxlliary stcanii plants In Salt Lake City It will be the > most modern and economical generat ing and distributing station that can be r I built It will be used first aa a receiving re-ceiving station for all hightension trnnsmliwlon circuits Second as a distributing dis-tributing station foi the light power and street railway circuits hi Salt Lake City and third as an auxlllhry generating gene-rating station to be used In case of breakdown of any of the waterpower plants or tranmnlahlon linen The generating machinery will be specially designed with a view I to be able to be started on short notice incase case of emergency The designs will provide for the 4na allailon of steam engines of large capacityr atfirst andy and-y It is very probable that steam turbines will be used As soon as the gas engine has been sufficiently developed to allow al-low of Its use for generating electricity In large units gas engines will be installed in-stalled as additional machinery may be required In this station there will also be located lo-cated all the stepdown transformers switchboards arc lighting machinery rotary transformers and other apparatus appara-tus required for distributing power and I light In Salt Luke City Provision will also bo made for the erection of a storage stor-age battery which will be used for regulating reg-ulating and for emergency During the past year the company has expended approximately 100000 In reconstructing repairing renewing and modernizing Its distributing system sys-tem Further large amounts will be spent during the coming year and when the improvements outlined above are all completed the company will be In a position to sell more than twice as much power as It does at present and to give a service that will be absolutely abso-lutely reliable The company also owns qulto an extensive ex-tensive gas plant In Salt Lake City also a smaller plant in Ogden City In Salt Lake there are about thirty miles of gas mains The works are located In a two and halfacre lot in the west end of the city where there Is every facility for the delivery of coal The plant at present has a capacity of 100 000 cubic feet per day and Is a mixed coal and water plant so designed that either or both systems can be used ln the manufacutre of gas tit a time Designs De-signs have been made for the extension of this Rant as the demand for gas increases up to a capacity of 1000000 cubic feet per day Considerable work has been done during the past years and all work that is being carried out is inline In-line with the general design so that in a comparatively short time the com panys plant will be absolutely modern in every respect The personnel of the administrative staff and management of the company Isas follows Hon Joseph JR Smith president Col John R Winder first vicepresident Col Thomas G Webber second vicepresident MrL S Hills treasurer each of whom with the
