Energy analyst Sampson Mamphweli warns that South Africa is heading towards a total blackout. eNCA reports that earlier today, Eskom warned of the possibility of Stage 6 power cuts. In a briefing earlier, the power utility explained it had suffered significant losses overnight. It adds the current strike by employees also poses a serious challenge. “The strike itself came at the wrong time because it came at a time when the system is heavily constrained with more than 40 megawatts that’s not available due to a number of factors like breakdowns,”¬†Mamphweli said.
