Johannesburg – Eskom is on Friday calling on everyone in the country to use electricity sparingly as it battles to keep up with demands.
South Africa is having to put up with another day of stage two load-shedding, which is expected to last until at least 5am on Saturday.
But Eskom said the power system remained vulnerable and unpredictable, meaning the situation could change with little notice.
The utility is trying to return generation units to service at its ageing power plants and said it was working to replenish emergency reserves.
