Majuba Power Station
History
This 4 110 megawatt station, constructed at a cost of R11.9 billion, is one of the five biggest power stations in the world and the first to have been officially opened in South Africa after 1994. Construction started in 1983 and the first of its six units was placed in commercial operation in April 1996. The remaining five units were added at a rate of one unit per year, with the final unit coming into operation in April 2001.
 
Majuba Power Station has always generated a great deal of interest and speculation. The original planning proposal for Majuba as contained in the Planning Proposal for Expansion Schemes dated January 1982, allowed for Unit 1 to start production in September 1988, with subsequent units at one year intervals (Unit 6 in September 1993).
