JOHANNESBURG - Power has been restored to all areas affected by the Robertsham substation fire.
City Power technicians managed to return the last feeder boards to service on Wednesday.
It is apologising for the inconvenience after some residents were left without power for up to 48 hours.
The blaze broke out on Monday night, plunging 16 Joburg south suburbs into darkness.
The cause is not known at this stage but investigations are underway.
Authorities are not ruling out sabotage.
