Abstract: Clean safe and affordable energy is a necessity for every human being. Electricity, as an important modern energy, is a basic substance not only for national but individual and household development. In Zambia, only 40 percent of a population of about 17 million has access to electricity consisting of 67 and 4 percent urban and rural area access respectively. Since 1970 Zambia’s electricity generation has largely been solely on the southerly located part of Zambezi as a major hydro power source.
