In Kowloon and the New Territories, electricity is supplied by China Light & Power Co., Ltd., whose services extend to Lantau and several other outlying islands.
In 1959, sales were again substantially increased, while the Com- pany's generating capacity and network were further expanded. New connexions included multi-storeyed apartment buildings in the business centre of Kowloon, and factories in Kwun Tong, Castle Peak and Tsuen Wan. Severe electrical storms in the summer taxed the Company's repair facilities, but in all cases service was restored with a minimum of delay.

The normal electricity supply, is alternating current of 50 cycles, at 200 volts for single phase and 346 volts for three-phase. Main transmission over long distances is carried at 33,000 volts, while ordinary distribution is effected at 6,600 volts. The network is made up of underground cables in the urban districts and, to an increasing extent, in rural areas, while the remaining lines consist of overhead wires. The total length of the main system at 30th September 1959 was: 33,000 volts, 160.6 miles; 6,600 volts, 207.23 miles. At the same time, the Company had 203 substations, and 611 transformers totalling 477,400 KVA.
The Generating Station is situated facing Kowloon Bay at Hok Yuen. During the year, the extensions planned in 1955 were completed, bringing the total capacity to 182,500 kilowatts. The three latest turbines have an output of 30,000 kilowatts each and consume steam at a pressure of 600 lbs. per sq. in., and a temperature of 850°F., while the remaining machines operate at 400 lbs. per sq. in. and 695°F. respectively. All steam is raised in boilers which are at present fired by fuel oil exclusively. Further extensions are planned to deal with the ever rising demand.
Approximately 646,901,300 units of electricity were generated during the financial year 1958-9 of which 552,046,000 were sold. Total sales in units were as follows:
