Operator acknowledges interruption on the Parkhurst line
The City Power statement was published at 23:05:44 SAST on 22 October, equivalent to 21:05:44 UTC. It links the interruption to a trip at Delta Substation on the Parkhurst line. That is the time of the public statement, rather than a verified outage start time. No precise onset is available in the evidence.
The operator names Forest Town, Westcliff, Craighall Park, Saxonwold, Parkview and Greenside. Its notice establishes a reported interruption affecting customers in these areas, without a complete street list or customer count. It does not establish that every property within each named area lost electricity, and it provides no basis for describing the interruption as citywide.

Investigation and restoration outlook
City Power says operators are being mobilised to investigate the underlying cause, with their findings intended to guide restoration. This describes a planned response. It does not confirm that a team has arrived, that a fault has been located or that repairs are complete. The available statement provides no estimated restoration time or confirmed restoration report.
The incident account currently rests on one primary operator statement. Individual premises have not been independently checked, and the available record does not prove a link to older or nearby interruptions. The substation trip identifies a network event; the underlying cause remains under investigation. Further findings would be needed to explain the fault and establish a supported restoration outlook.
Planning for essential devices
The runtime calculator can help compare essential-device demand with battery capacity. The internet backup planner covers connectivity needs while electricity is uncertain. These tools support household preparation; they do not confirm supply at a particular property or predict a utility repair deadline. For this incident, City Power’s stated position remains mobilisation for investigation without a restoration estimate.
