The electricity supply to Northpine and Wallacedene was restored on Saturday afternoon, said Eskom.
This came after Eskom customers in these areas were without electricity supply since the morning due to network overload, Eskom said in a statement.
It said the repairs forced them to switch off supply to those areas, which caused the network overload.
Supply was also interrupted to Bothasig as a result of vandalism, in the early hours of Saturday, Eskom said.
The public can report theft and vandalism of electrical infrastructure to Eskom’s crime line at 0800 11 27 22 or the police.
