About this data. OurPower compiles this record from public power outage notifications published by City Power Johannesburg. Each entry is a reported outage with its reported duration. We only show what City Power publicly announces, so some localised faults never appear here. "Time to restoration" is measured from when the outage was first reported, not from when it began, so it's a proxy rather than an exact repair time. This record starts from April 2026.
