City Power reports full restoration for the named Inanda, Illovo and Athol outage.
The interruption was reported on the night of 10 October; its exact start time is unknown.
Cable fault is the operator’s attribution; customer count and exact switching time are not supplied.
Restoration announcement covers three named areas
The operator published its notice at 11:23 SAST on 11 October. That is the announcement time, rather than a confirmed time when supply was switched back on. The statement reports full restoration to customers in the three named areas. It provides an operator account of the reported event, without an address-by-address audit of individual electricity connections.
City Power says the interruption was reported the previous night, 10 October. A reporting date is not an exact onset time, and the notice gives no reporting clock. The duration therefore cannot be calculated from the two dates. No customer or connection count accompanies the announcement, so the available statement supports no numerical measure of the outage’s scale.
What the sources tell us, and what they do not
- Named areas
- Inanda, Illovo and Athol, Cydna Substation, Johannesburg
- Operator-reported status
- Full supply restored, according to City Power
- Operator attribution
- Cable fault; technical details not supplied
- Affected connections
- Count unknown
Cable fault remains the operator’s attribution
The announcement attributes the interruption to a cable fault. It does not identify the equipment involved, explain the technical root cause or describe the repair procedure. The cause is reported with attribution to City Power. The available wording supplies no basis for assigning responsibility or claiming an independently verified technical diagnosis.
The restoration statement applies to the named event reported on 10 October. Earlier Cydna cable-fault and trip reports have an unresolved relationship to this interruption. A shared substation name does not establish that they describe the same event. Their earlier affected areas and percentages are therefore not used to expand this report. The notice also does not establish supply conditions across Johannesburg or verify every individual property.
Planning essential backup power
The runtime calculator helps compare essential device loads with battery capacity. The internet backup planner covers router and modem power, while backup essentials offers a preparation checklist. These tools help plan for future interruptions. They do not verify the condition of a connection or resolve the missing onset, switching time and customer count in this report.
