Parts of Jo'burg without power
The cause of the power failure in Johannesburg was unknown, while operators worked on the problem.
JOHANNESBURG - City Power said on Saturday evening it was still not clear how long it would take to restore power to various areas in Johannesburg's northern suburbs.
Residents in Highlands North, Sydenham, Killarney and Sandringham had been without electricity since early on Saturday morning.
City Power's Louis Pieterse said the exact cause of the failure was still being investigated.
He said power would be restored as soon as possible.
"Our operators are on site and if all goes according to plan, we hope to start restoring power in the next two hours."
