Eskom’s newest coal-fired power stations, Limpopo-based Medupi and Mpumalanga-based Kusile have suffered setbacks since their commissioning, some of which are yet to be finalised. Because Eskom ordered boilers of such a high capacity – at about 800 MW a unit – this meant that the power utility suffered from teething problems associated with plant and equipment deployed in few other places in the world. This meant Eskom had to work with the boiler manufacturers to understand the issues and work together to solve them.
