[edit] General
In 1993 Duvha became the first power station in the world to be retrofitted with pulse jet fabric filterplants on three of its six units. These plants contribute largely to the reduction of air pollution by removing 99.99% of the fly ash which otherwise would be released into the air through the station's chimneys.
[edit] History
Construction of Duvha Power Station started in November 1975 and the last unit came into operation in 1984. At the time of its construction, Duvha was a giant of superlatives: it cost a staggering R1.6 billion to build, its chimneys were largest freestanding concrete structures and its mine the largest open-cast colliery in the Southern Hemisphere.
[edit] Safety
Duvha's excellent safety record is proven by the fact that it has been awarded NOSCAR status twice already by the National Occupational Safety Association (NOSA). The last award was made in March 2001.
