City Power identifies Siemert Substation (Sivewright) in its New Doornfontein notice.
Operators are on site investigating the cause, according to the utility.
The reporting timeline is uncertain; no common outage duration or restoration deadline is established.
What City Power has confirmed
The utility published its statement at 11:32:29 South African Standard Time on 3 November, equivalent to 09:32:29 UTC. That is the publication time of the notice, rather than a verified start time for the physical interruption. City Power says the outage was reported that morning. A report reaching the operator does not establish when electricity first failed at each property.
The notice establishes an on-site investigation at the time of the update. It does not establish that a technical fault has been diagnosed, repairs completed or power restored. Siemert Substation (Sivewright) is the network reference supplied by the operator; that name alone does not identify every affected circuit or address.

Start time and affected boundary remain unclear
The reporting timeline is disputed. Resident accounts refer to Saturday, 31 October, while the operator says the outage was reported on the morning of 3 November. These accounts do not establish an uninterrupted outage since Saturday for all customers. Exact addresses and circuit links have not been verified, so a single duration cannot be assigned to the whole area.
New Doornfontein is the named affected area, but the notice supplies neither a street list nor a connection total. It does not establish loss of supply at every property or across Johannesburg. The connection between Maboneng resident complaints and this investigation remains unresolved. The separate Siemert incident reported restored in October cannot establish the present supply position or continuity with this interruption.
Planning for essential devices
The grid-down essentials guide, internet backup guide and runtime calculator explain essential loads and backup capacity. These resources support household preparation; they cannot confirm electricity at an individual address or predict when network repairs will finish. A later operator finding is needed before a supported cause or recovery estimate can be reported.
