There are no scheduled power cuts for this week, Eskom said on Monday.

"[The] system will be tight but no load shedding is planned at this stage," Eskom spokesperson Andrew Etzinger said in a statement.

"We are starting the week in a good position as we were able to replenish our emergency reserves over the weekend," he said.

The power utility urged consumers to use electricity sparingly.

It encouraged consumers to switch off geysers, air conditioners, pool pumps, and all non-essential appliances throughout the day to alleviate pressure on the system and limit the need for rotational load-shedding.

Last month, a coal storage silo at the Majuba power station in Mpumalanga collapsed, resulting in widespread power cuts. The silo held more than 10 000 t of coal and affected coal supplies to all six units at the power station.

Maintenance at the hydroelectric facility Cahora Bassa in Mozambique also had an impact on power supply.
