NATIONAL ASSEMBLY QUESTION 1310:
Dr S M van Dyk (DA) to ask the Minister of Energy:
What is the total loss in energy that resulted from the recent explosion at
the Duvha-More power station? NW1453E
The turbine, generator and associated components of Unit 4 of Eskomâs Duvha
Power stations were damaged at approximately 22h00 on 9 February 2011
during the course of a routine turbine over-speed statutory test.
There was no explosion.
When operating at full power, Duvha Unit 4 supplies 575MW of electricity to
the national grid. This is approximately 1.4%of Eskomâs total net supply.
In terms of energy, at a typical load factor of 80%, this equates to
approximately 4000 Gigawatt hours (GWh) per year (1.6% of the projected
energy demand for FY2011-2012).
