The total installed capacity in the Guangdong power system will be 1871 MW by the end of 1980, comprising 1019 MW thermal plants and 852 MW hydro plants. The largest unit capacity is 125 MW.

demand in 1980
The system maximum
is 1450 MW. The maximum demand is expected to grow at an average rate of 10.8% to 4050 MW in 1990.
In order to meet the growth in system demand, it is planned to construct Shajiao Power Station and Maoming Shale-fired Power Station and to extend Shaoguan Power Station by 2 x 200 MW sets by 1987. Several medium-sized hydro power stations will also be commissioned. The interconnection between the Guangdong and Guangxi systems is scheduled for implementation around 1990. 500 kV transmission system will be formed in stages during this period.

A
Guangdong power systems are shown
There are two major power companies operating in Hong Kong, viz, China Light and Power Company Limited (CLP) which supplies Kowloon Peninsula, New Territories and Lantao Island, and Hongkong Electric Company Limited (HEC) which supplies the Hong Kong Island and Lamma Island. The total installed capacity in 1980 is 3472 MW, all being oil-fired plants. The largest unit capacity is 200 MW.
The highest operating voltage in Hong Kong is 132kV. By April 1981, the CLP and HEC systems will be interconnected by 132kV cables.
The maximum demand for the Hong Kong system in 1980 is 2774 MW. The maximum demand is expected to grow at an average rate of 8.8% to 6465 MW in 1990..
