South Africa’s electricity minister proposed a plan to stave off deeper power cuts by increasing the use of diesel turbines along with building more storage capacity to store the fuel. State-owned utility Eskom Holdings will need to increase its budget for diesel, Minister Kgosientsho Ramokgopa said, according to a copy of a presentation seen by Bloomberg. A special dispensation could reduce the cost by allowing Eskom to directly purchase the fuel, the plan showed.
