Another day of load shedding ahead
Eskom says it's working to build up more power reserves by today to minimise disruptions for Monday.
Large areas around the country have been left without power.
This is the third time the utility has implemented load shedding this year.
On Friday, the power utility started with scheduled blackouts across the country.
Eskom has been experiencing problems since the collapse of a coal silo at the Majuba Power Station in Mpumalanga earlier this month.
The collapse led to rolling blackouts across the country on 2 November.
The power grid says it's working to build up more power reserves by the end of today to minimise disruptions for South Africans and businesses tomorrow morning.
Eskom's Tony Stott says although the power grid is still under severe strain he hopes to see some improvements by later today.
"We have had some units come back in today and we hope to have more coming back and that should ease the situation going into the week."
Stage two load shedding resumed over some parts of the country yesterday, with some areas experiencing lengthy outages.
Stage two means the frequency of power cuts has been increased.
Wet weather conditions expected in Johannesburg this afternoon could place further strain on the already fragile power grid.
