“The cold and wet weather has resulted in increased demand for electricity but the power grid is stable,” said spokesman Andrew Etzinger.
“No load shedding has been planned at the moment.”
Earlier this 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 tons of coal and affected coal supplies to all six units at the power station.
An investigation into the collapsed silo has since been launched.
