Restoration reported for Glenvista
The latest notice identifies Glenvista as the area where customers have had power fully restored. Mulbarton is the substation named in the heading, rather than a separate confirmed affected neighbourhood in the body of the statement. The available evidence supports reporting restoration for the customers City Power names, without extending that conclusion to other parts of Johannesburg or every supply connected to the substation.
City Power attributes the outage to a cable fault. Its brief restoration announcement does not specify which cable failed, how the fault developed, or the technical repair sequence. There is no verified basis here to describe the interruption as a wider grid collapse, scheduled load shedding or equipment failure at another facility.
What the sources tell us, and what they do not

- Cable fault, according to City Power
- Latest operator report
- Power fully restored to customers in Glenvista
- Affected customers
- Count not supplied

- Unknown; publication time is not the switching time
Timing and impact remain limited
The 12:26 SAST timestamp records when the operator published the update on Saturday, 10 October. It is not an exact switching time for every connection. The outage’s precise onset is also unknown, so the available information does not establish a reliable duration. No customer count or address boundary is supplied, and there have been no independent checks of individual connections.
Residents reading this report should therefore distinguish the operator’s restoration announcement from an address-specific service check. The report records City Power’s statement about the named area. It cannot determine whether a particular property has an unrelated local fault, or whether a later interruption has occurred. Those questions require fresh local information beyond this notice.
