The National Energy Regulator of South Africa has granted freight logistics group Transnet a 7.69% increase in its allowable revenue to R5.68-billion for 2019/20, which translates to a 10.95% increase in pipeline tariffs. Should Energy Minister Jeff Radebe decide to use the pipeline tariff as a proxy for the cost of transporting fuel to Gauteng, the increase will have a 4.5 c/l impact on the petroleum transportation charge for the Durban-to-Alrode destination, the regulator said in a statement on Monday.
