The affordable education loan option
Members of the media continued to keep watch outside former president Nelson Mandela's home in Houghton, north of Johannesburg, on Saturday.
Cameramen and reporters took shelter from the heat under gazebos directly across Mandela's home, while others sat in their cars.
Neighbours and visitors were seen taking pictures outside the home where messages of support had been laid.
Two police cars were parked at the corner of the house, and another eight cars parked near the gate, one with a military number plate.
A back-up generator was cordoned off with yellow tape on 11th avenue, parallel to the street where the ailing icon lives. It was being guarded by a City Power official.
On Thursday, Mandela's home was among those hit by widespread power outages in Johannesburg.
The sounds of generator could previously be heard coming from behind the walls of Mandela's home, however it was silent on Saturday.
Earlier, City Power spokesman Sol Masolo said power had been restored to about 80 percent of Johannesburg.
The power outages have been blamed on sabotage, allegedly by disgruntled workers who embarked on an unprotected strike on Wednesday. They were unhappy about a new shift system being implemented.
Mandela was discharged from the Medi-Clinic Heart Hospital in Pretoria on Sunday to recuperate at home following a lengthy stay for a recurring lung infection.
His home has been reconfigured to ensure he receives the correct care, and some staff who had been at the hospital are also caring for him at home.
His condition was last described by the presidency as critical and stable, but at times unstable. - Sapa
