The South African Petroleum Industry Association (Sapia) is not anticipating a domestic diesel supply crunch this winter as a result of a spike in generator-related demand, despite ongoing warnings of possible higher levels of loadshedding and the prospect of Eskom, businesses and even some households turning to the fuel in an effort to mitigate the impact of regular power cuts. Sapia executive director Avhapfani Tshifularo tells Engineering News that domestic diesel demand has remained relatively static over the past few years and that the average monthly consumption is about 1.1-billion litres currently.
