Not illustrated. 1916 Excerpt: ... The recent development of Detroit as a factory city is responsible in a measure for the unusual increase of commercial load, and the resulting influx of factory employees has developed the residence service in the newer sections. Fig. 188 records the increase in total kilowatt-hours' output, total commercial kilowatts connected, number of meters, and the total horsepower of motors, both direct-current and alternating-current, for the years 1903 to Nov. 1, 1911. In addition to its own lighting and commercial load, the Detroit system furnishes energy for the associated Eastern Michigan Edison Co., operating in the suburban district surrounding Detroit. About one-fifth of its total generated output is purchased by the Detroit city railways for operating cars in all outlying sections of the city. Another unusual traction load taken over by the central-station company within the year is the operation of the Detroit River tunnel of the Michigan Central Railroad. The tunnel substation takes its energy supply through a 500-kw. motor-generator set, being arranged with a storage battery so that the peaks of demand of train acceleration are not felt by the central-station system. Figure 187 taken from Hirshfeld's paper (A.S.M.E., December, 1916) shows the continuation of growth in its relation to population, and similar curves are given in Figs. 190,191 and 192 for Melbourne, Australia. Curves of daily maximum loads show the variation of demand throughout the year and should be studied very carefully as much may be learned from them. Cost Curves at Variable Loads.--Dr. Klingenberg, in " Bau. Gr. Elek.," has shown a very convenient method for showing graphically the economy of central stations. This is possible where it is convenient to get the actual cost a...
