Doctors are concerned about the diesel supply after a day-long power outage in Johannesburg.
The Ridge substation in the CBD supplies five health facilities: the Charlotte Maxeke Academic Hospital, Nelson Mandela Children's Hospital, Park Lane Hospital, Brenthurst Clinic and Rand Clinic.
The outage occurred at 11:00 on Sunday when a burned feeder board disrupted power to vital health facilities and impacted customers in Berea, Hillbrow, Parktown and surrounding areas.
