Duvha Power Station
power plant in South Africa
Duvha Power Station in Mpumalanga, South Africa, is a coal-fired power plant operated by Eskom. The 300 metres (980 ft) tall chimneys at Duvha are the second and third tallest structures in Africa, only a chimney located at the Secunda CTL plant is taller.
History
Construction of Duvha Power Station started in November 1975 and the last unit came into operation in 1984.
In 1993 Duvha became the first power station in the world to be retrofitted with pulse jet fabric filter plants 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.
On 8 January 2003, Unit 2 generator exploded while being returned to service after a malfunction. On 9 February 2011 another unit failed catastrophically while performing over speed testing. The units are over speed rated at 3600 rpm and the last recorded speed before failure was 4250 rpm.
It was the first power station in South Africa to have a black power station manager, Ehud Matya.
Power generation
The station consists of six 600 MW units with a total installed capacity of 3,600 MW operating with a turbine efficiency of 37.6%.
Begin with the source’s own compact description: “Duvha Power Station” is power plant in South Africa. The dossier treats that line as a proposition to test through Duvha, Power and Station, not as a finished interpretation.
Why this record matters
The phrase “power plant in South Africa” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jul 31, 2026. The linked authority identifier is Q2320823. Authority coordinates are -25.964, 29.337. 1 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1975, 1984, 1993 and 2003.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
