Eskom says it will aim to suspend load shedding during peak traffic hours in the morning and evening.
On Tuesday, it is aiming to suspend power cuts between 6am and 9am, and again between 4pm and 6pm. This comes after it suspended rotational power outages between 4pm and 6pm on Monday for the first time in a bid to "help ease traffic congestion".
"Suspending load shedding during the peak traffic hours is a pilot programme aimed at achieving an appropriate Loadshedding Philosophy for the country," the utility said in a statement. "As this is not possible everyday, it will be confirmed each day, dependent on the risk based on the available capacity and emergency reserves on the day."
Power rationing is set to continue until Thursday morning at 6am.
"We regret that load shedding has a negative impact on South Africa. Critical maintenance is being done on units that are currently on planned outages as well as some of those on unplanned outages to ensure timeous return to service," the utility said.
