Developing story: City Power is still assessing the damage and has not given a firm restoration time.
Parts of Johannesburg have been without electricity since the early hours of Sunday after a fire at the Mayfair substation, according to City Power.
Who is affected
Areas without power include Mayfair, Crown, Brixton, Vrededorp and surrounding suburbs. The outage also affects the SABC offices in Auckland Park and Garden City Hospital, as well as other communities and businesses. City Power has not given the number of customers affected.
What City Power says
City Power spokesperson Isaac Mangena said technical teams are still assessing damage to seven cables, a transformer and electrical panels. City Power said gradual restoration is expected to begin on Monday, provided repairs and safety tests succeed.
The utility said heavy rain is complicating the work. It also said an alternative supply route was ruled out because of the risk of overloading the network.
What we do not yet know
The cause of the fire has not been established. City Power has not said how many customers are affected, how long full restoration will take or whether the hospital is running on backup power.
Residents should follow City Power's official channels for updates.
