PUBLIC WORKS AND UTILITIES
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 7%. Special rates are quoted for bulk consumers of industrial power.
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 1960 this Company's network expanded again. New consumer connexions caused a greatly in- creased load which was, however, met at all times, and planning continued for a considerable strengthening and extension of the system together with construction work for the installation of plant to generate an additional 120 MW.
The normal electricity supply is at 346/200 volts, 50 cycle AC, with transmission at 33 kV and primary distribution at 6.6 kV. To meet the continued demand economically, equipment was ordered for the introduction of higher transmission and distribution pressures at 66 kV and 11 kV. On 30th September 1960, the length of the main system was: 33,000 volts, 190 miles; 6,600 volts, 248 miles; and there were 240 substations and 713 transformers total- ling 589,400 KVA. The Generating Station is situated facing Kowloon Bay at Hok Yuen and has a capacity of 182.5 MW. The two 60 MW turbines now being erected, together with associated 555,000 lbs per hour boilers, will consume steam at a pressure of 900 lbs per square inch and a temperature of 900°F, while the recent 30 MW turbines operate at 600 lbs per square inch and 850°F and the earlier sets at 400 lbs per square inch and 695°F. All boilers are fired exclusively by fuel oil. About 797,816,600 units of electricity were generated during the financial year 1959-60 of which 679,498,691 were sold as follows:
