PUBLIC WORKS AND UTILITIES

The system transmission voltages are 66 kV and 33 kV. Primary distribution is carried out at 11 kV and 6.6 kV. The secondary distribution voltages are 346 volts, three-phase, four-wire and 200 volts, single-phase. The frequency of the system is stabilized at 50 hertz a second. The obsolescent 6.6 kV system is gradually being replaced by 33 kV and 11 kV systems. Maximum demand on the company's generating plant rose to 251 MW in 1968, an increase of 14.2 per cent over 1967. The number of consumers increased by 6.9 per cent during the year, and sales of electricity amounted to 983.9 million kWh, an increase of 10.5 per cent. These were made up of: domestic and residential, 293.2 million kWh; commercial, 520.2 million kWh; industrial, 164.4 million kWh; street lighting, 6.1 million kWh.

For domestic, commercial and small industrial consumers, the company has separate block tariffs ranging from 25 cents to 12.4, 14 and 12 cents per unit respectively, depending on quantity con- sumed. Special rates are quoted for bulk supplies of electricity.

The Cheung Chau Electric Company Limited supplies Cheung Chau Island which contains some small industries and a population of fisherfolk who founded the company in 1913 as a community project. It is now operated by commercial interests and it supplies power on a 50-cycle, three-phase, four-wire system of 200/346 volts for domestic, commercial and industrial purposes.

The charges for electricity have been gradually lowered by modernizing and increasing the efficiency of the generating plant. Current rates are 57 cents per unit for lighting and 25 cents per unit for domestic and industrial power. Special rates are given to bulk consumers.

The Hong Kong and China Gas Company Limited supplies Hong Kong Island, Kowloon and the New Territories. Town gas is available throughout the urban areas, including Repulse Bay on the island, and the industrial towns of Kwun Tong and Tsuen Wan in Kowloon. Liquefied petroleum gas (or bottled gas) is offered to customers who are out of reach of the town gas supply.
