Eskom laments poor quality of coal

Eskom COO Jan Oberholzer has called on coal mining companies to "play ball" and improve the quality of the coal they supply to the utility. He has also outlined the massive challenges facing the utility and said Eskom was holding out for the National Energy Regulator of South Africa (Nersa) to approve its latest application for tariff increases of up to 15% a year over the next three years.
