PRESIDENTIAL ADDRESS. 45 



The extension to the outlying suburbs has made necessary 

 a very considerable increase in the substations; in 1904 

 there were five, in 1907 eight, in 1910 seventeen, in 1913 

 sixty-three, and at the present time about one hundred, 

 besides a large number of pole transformers. The capital 

 expenditure, which at the end of 1904 amounted to £151,894, 

 has grown until at the end of 1916 it was £2,860,000. 



The Electric Light and Power Supply Corporation was 

 formed in 1908, they built works on the water side near 

 the Iron Gove Bridge at Balmain, in order to carry out a 

 contract entered into with the Balmain Municipality to 

 supply electric current, and also destroy their garbage, the 

 waste heat from this being used for the generation of steam. 

 The supply which has been extended to the adjoining muni- 

 cipalities of Newtown, Petersham, Leichhardt and Ashfield, 

 commenced in September 1909, since which time the suc- 

 cess of the company must be most gratifying to its share- 

 holders and officials. 



The power station is equipped with two reciprocating 

 triple expansion engines and three steam turbines driving 

 generators of 5050 kw. total capacity, supplying an alter- 

 nating three-phase current at 5000 volts which is conveyed 

 to twenty-two different transformer substations by bare 

 overhead mains and from them supplied to consumers at 

 415 volts. 



The area within which the company has the sole right to 

 supply electric light and power covers ten square miles 

 with a population of 146,000, the street mileage being 212, 

 number of premises, including many large factories, 29,762, 

 with a capital value of £17,620,741. 



The expenditure to October 1916 amounted to £266,951; 

 116 miles of streets being lighted, of which 98 miles are 

 reticulated for private lighting, the high pressure trunk 

 mains from the power house to the district substations 

 amounting to 33 miles.
