Sandringham power outage: City Power reports supply restored
City Power reports that electricity has been restored to customers in Sandringham, Johannesburg, supplied through Gresswold Substation. Its notice on 18 October 2026 attributes the outage to a cable fault. The utility had acknowledged an interruption in Sandringham on 17 October, but the later notice does not explicitly repeat that date or provide an incident number.

In 20 seconds
City Power reports restored supply to customers in Sandringham through Gresswold Substation.
The operator attributes the outage to a cable fault; the customer count and exact affected streets are unknown.
The notices do not establish a uniform outage duration or a restoration statement for other Gresswold areas.
What the restoration notice establishes
The 18 October operator statement names Sandringham and says power has been restored to customers there. It identifies Gresswold Substation and attributes the outage to a cable fault. This is the utility’s account of recovery in the named locality. The available evidence does not include independent confirmation of the supply condition at each property.
The notice was published at 14:12 SAST on 18 October, corresponding to 12:12 UTC. That timestamp records the statement’s publication, rather than an exact physical restoration time. Neither an affected-customer total nor a detailed street boundary is established. The statement therefore cannot be used to calculate a uniform interruption duration for households.
What the sources tell us, and what they do not
- Named area
- Sandringham, Johannesburg; supplied through Gresswold Substation
- Reported cause
- Cable fault, according to City Power
- Affected customers
- Count unknown
- Restoration report
- Supply restored to Sandringham customers, according to City Power’s 18 October notice
Earlier acknowledgment and limits of continuity
At 17:00 SAST on 17 October, City Power acknowledged an outage affecting customers in Sandringham and said operators would be dispatched to investigate. Its reference to possible surrounding areas did not confirm that those places were affected. The publication time is distinct from the unknown time when electricity first went off.
The two notices are kept together because they come from the same operator and name the same locality. However, the 18 October restoration notice does not explicitly identify the 17 October interruption by onset date or incident number. No continuous overnight duration is assigned. Reports concerning Kew West, Kew or Wynberg and other Gresswold interruptions remain separate; this statement does not establish a wider substation-area or Johannesburg all-clear.
