Power System Overview
INTRODUCTION
Electric energy occupies the top grade in the energy hierarchy. It finds innumerable uses in
home, industry, agriculture and even transport. The reasons why it is very attractive as compared to
other forms of energy are its ability to be transported almost instantaneously, its use can be controlled
more easily and its almost pollution free at consumer’s level. The per capita consumption of electricityin any country is an index of the standard of living of the people in that country.
The per capita consumption of electrical energy in some of the countries is (data from 2001):
Iceland 31,147.292 kWh
Norway 24,011.233 kWh
Canada 16,279.411 kWh
USA 12,924.224 kWh
Japan 7,701.962 kWh
United Kingdom 5,773.615 kWh
Malaysia 3,724.977 kWh
Kenya 145.803 kWh

In Malaysia, the total installed capacity as of 2005 was 17,314 MW. TNB’s installed capacity
was 10,760 MW while IPP’s installed capacity is 6554 MW. The nation’s maximum demand is about
12,023 MW so we have a reserve margin of about 30%. In the year 2007, the maximum capacity is13000 MW. For year 2007, the maximum demand is almost 1300 MW.
