SASOLBURG - South Africa’s biggest fuel producer, Sasol, has reportedly restarted the Natref refinery in Sasolburg it owns with TotalEnergies after delayed oil deliveries last month resulted in a shutdown. The disruption caused Sasol to declare a force majeure on petroleum products, which remains in effect. The company said in response to emailed questions from News24 that the 108,000 barrel-a-day plant is now "online and production ramp-up is in progress". Natref’s shutdown also meant the whole of South Africa’s oil-refinery fleet was out of action as a series of other facilities suspended production over the past two years. News24 reports the plants have faced costly upgrades to meet pending cleaner-fuel regulations. South Africa has delayed the implementation of those rules from next year to 2027, which Sasol has welcomed.
