2,077,350 kilowatt hours. New primary substations at Hospital Road West and Taikoo (Westlands Road) were completed during the year. The rebuilding of Zetland Street primary substation is nearing completion. Forty-two secondary substations were among the distribution projects completed in 1962.
The amount of electricity generated in 1962 was 596,315,185 kilowatt hours, an increase of 11.25 per cent over the previous year, and the number of consumers at the end of the year was 111,408, an increase of 4.93 per cent. The total sales of electricity for 1962 were:

Charges for electricity range from 28 cents to 15.4 cents a unit for lighting and 12 cents to 11.4 cents a unit for power. These rates are subject to a variable fuel surcharge which, at the end of the year, was seven per cent. Special rates are quoted for bulk con- sumers of industrial power.
Electricity for Kowloon and the New Territories, including Lantau Island and many other outlying islands, is supplied by the China Light and Power Co Ltd. The increased demand for electrical energy experienced in recent years continued unabated. The capacity of the generating station at Hok Yuen, facing Kowloon Bay, was increased to 302.5 MW during 1962 by the addition of two 60 MW turbo-alternator sets and associated boilers. Steam for the turbines is supplied at 900 pounds per square inch at 900°F and the output of each generator steps up from 11,800 volts to 33,000 volts for transmission to various bulk-supply sub- stations. The substations use automatic voltage controlled trans- formers to control the voltage at 11,000 or 6,600 volts to supply distribution and factory substations. Distribution to domestic and small industrial consumers is at 50 cycles AC, 200 volts single phase or 346 volts three phase.
Two more 60 MW turbo-alternator sets, including boilers, are on order. Switchgear, transformers and oil-filled cables are also on order to inaugurate a 66,000 volt transmission system. The first
