The lack of adequate and reliable electricity supply has been directly affecting the South African economy since the first series of blackouts occurred in 2008. Recognising the looming crisis, Eskom and the Department of Energy launched the New Build Programme in 2005 whereby previously mothballed coal-fired power stations such as Camden and Grootvlei were recommisioned and two new modern coal-fired power stations, Kusile and Medupi, with a generation capacity of 4800MW were commissioned to be built. However, delays in the building of these new power stations, inadequate maintenance of existing plants, along with a steady increase in demand relative to a stagnant supply culminated in a second wave of load shedding across South Africa at the end of 2014. At the time of writing, South Africa’s economy is in desperate need of an expansion of electricity supply to facilitate economic growth and development. In this regard, the role of Kusile and Medupi is essential, and provides the motivation for the research conducted in this study.
