Eskom is in negotiations with miners for the possible development of a cost-plus coal mine dedicated to supplying the 4,800MW Kusile coal power project, Eskom senior project manager Karabo Rakgolela told the Mining Coal Symposium in Middelburg on 5 September. Cost-plus has proved controversial, with critics arguing that mines are not incentivised to operate efficiently under the structure, which involves Eskom paying for mining costs.
