TABLE B.-Power demand in California

[Southern California, by F. H. Fowler, American Society Civil Engineers, 1923; northern California, by T. A. Panter, city of Los Angeles, 1924]

1 Based upon hydro carrying 80 per cent of kilowatt hours and operates at 55 per cent capacity load factor. Based upon hydro carrying 85 per cent of kilowatt hours and operates at 60 per cent capacity load factor.

TABLE C.-Growth in power demand for city of Los Angeles, including system of Los Angeles Gas & Electric Co. but excluding rails

[Actua! Agures, 1905 to 1923, inclusive; 1924 to 1930, inclusive, estimated]

Average increase in kilowatt hours demand from 1916 to 1923, inclusive, was 20.5 per cent per annum compounded. This means that the demand doubles in a little less than four years.

Mr. PANTER. From what I have just read it is apparent that southern California has a great deal more steam developed than the north.

Any forecast made as to the future requirements for power must necessarily be based upon the records of the past and the analysis of the known factors affecting the future growth of the community together with all other statistics having a reasonable bearing upon the problem and corelated in accordance with the best judgment of the parties making such forecast. It is therefore apparent that certain assumptions must necessarily be made to form a basis for obtaining the final result.

Statistics obtained from the files of the railroad commission of the State of California show that the annual rate of increase for the entire State of California, from 1910 to date, has been at the rate of 9 per cent per annum compounded, and for the past seven years at the rate of nearly 12 per cent compounded annually.

In southern California the increase for the past 14 years has been at the rate of 13 per cent compounded annually, while for the past 5 years the increase has been at the rate of 15.5 per cent compounded annually, or in other words the demand now doubles practically every 5 years.

The attached table A shows that under certain reasonable assumptions as to percentage increase of growth, and also assuming that the hydroelectric plants will furnish 85 per cent of the total power,
