Kafue Gorge Upper Power Station


The Kafue Gorge Upper Power Station, is an operational hydroelectric power plant across the Kafue River in Zambia.

Location

KGU is located on the Kafue River, approximately, by road, south of Lusaka, the capital and largest city in Zambia. This is approximately  upstream of where the Kafue River empties into the Zambezi River, and approximately upstream of the Kafue Gorge Lower Power Station. The geographical coordinates of Kafue Gorge Upper Power Station are:15°48'25.0"S, 28°25'16.0"E.

Overview

KGU is an earth-rockfill dam with a concrete spillway with four radial gates. The electromechanical capacity is six generators of 150 megawatts each, for maximum capacity of 900 megawatts. The reservoir measures in surface area. The power generators and electromechanical power house are below ground. The water effluent from 900 megawatts Kafue Gorge Upper Power Station is used downstream to power the 750 megawatts Kafue Gorge Lower Power Station, in what is known as cascaded generation.

History

Construction of this power station started in 1967. In 1971, the first 150 megawatt turbine was installed and commissioned. Three other turbines were installed and commissioned in 1972. At some point between 1973 and 2009, two more turbines of 150 megawatts each, were installed to bring the generating capacity at the power station to 900 megawatts.
