Eskom says it is doing everything possible to ensure the burden of load shedding is spread evenly across the country.
Spokesperson Tony Stott says it's unlikely that any power outage of longer than two hours would be due to load shedding.
Eskom has now instituted its stage three load shedding schedule, which requires up to 4000 Megawatts to be shed.
Meanwhile, The Nelson Mandela Metro Traffic Department has pleaded with motorists to be extremely careful and patient at traffic lights, which are out of order due to the load-shedding power outages.
Senior Traffic Officer Lukhanyo Tinise said on Thursday that there had already been eight minor accidents, which could be directly linked to the traffic lights which were out of order.
Tinise said he was deploying all available officers for point duty at the busiest affected intersections, but that it was not enough.
He reminded motorists to treat all intersections with out-of-order traffic lights, as four-way stops, as the rules of the road stipulated.
