Environment, Forestry and Fisheries Minister Barbara Creecy reports that she has had no formal communication from Eskom with regards to it potentially not installing flue-gas desulphurisation (FGD) systems at the Medupi power station in line with a previous commitment to do so. FGD technologies are used to remove sulphur dioxide (SO2) from flue gases and one of the conditions of a 2010 World Bank loan of $3.75-billion to Eskom was that Medupi would progressively install such systems across all six units during future maintenance intervals.
