Despite the advanced age of Eskom’s coal fleet, coal power will remain a significant part of the domestic electricity mix for many years yet, with the new Medupi and Kusile stations having extended coal’s horizon by decades. South Africa should not be planning to build any new coal capacity, however. This is not only because of the environmental and climate impacts, but because such plants would only add to South Africa’s already steeply rising cost of electricity. What’s more, they are going to be hard, if not impossible, to finance.
