Gresswold power outage: City Power continues cable-fault investigation
City Power reported partial electricity supply at Gresswold in Johannesburg at 11:55 SAST on 7 October and requested the test branch for an additional fault. The investigation is linked to its 5 October acknowledgement. Its earlier 69% supply-restoration figure is historical; no new percentage or full restoration time is confirmed.

In 20 seconds
City Power says investigation continues at Gresswold on 7 October.
Approximately 69% power-supply restoration was reported on 6 October; it is not a current customer percentage.
Full restoration time, exact onset and affected customer count remain unknown.
Investigation continues on 7 October
The 11:06 SAST notice provides continuity for the investigation from 5 October through 6 October, with the 7 October notices providing further updates. It does not confirm completion of the remaining repairs or full restoration. The named substation area includes Bramley Park, Raumarais Park and Wynberg. The statements do not establish that every connection in those places has the same supply status, or that the interruption extends across Johannesburg.
At 10:02 SAST on 6 October, City Power reported approximately 69% of power supply restored and further investigations underway. Its 12:36 SAST notice repeated that position and requested the test branch to locate the remaining fault. The percentage described power supply in the operator’s wording. No denominator was given, and it cannot be converted into a customer total, household count or percentage of people.
What the sources tell us, and what they do not
- Named area
- Gresswold Substation; Bramley Park, Raumarais Park and Wynberg, Johannesburg
- Latest operator position
- Partial supply remains at 11:55 SAST on 7 October; earlier 69% supply restoration is historical
- Customers
- Absolute affected count unknown; supply percentage is not a customer count
- Full restoration
- Estimated restoration time unknown
- Fault information
- Cable-fault investigation with an additional fault discovered on 6 October
What remains uncertain
The exact outage onset, affected customer count and full restoration time remain unknown. An earlier apparent all-clear could not be verified from the original post. Its relationship to the continuing investigation is unresolved. A separate 6 October trip report in Bramley and Wynberg also has an unconfirmed relationship to this interruption; the historical 69% figure should not be applied to that separate signal.
At 11:55 SAST, City Power still reported partial supply and requested fault-location work. An adjacent post about final tests names Bramley and Wynberg but refers to a 6 October acknowledgement. Its exact relationship to this three-area interruption remains unresolved. It therefore does not establish final testing or full restoration across Gresswold. For a particular address, the area update provides context rather than a verified connection status.
Planning for uncertain supply
The runtime calculator helps compare essential device consumption with battery capacity. The internet backup planner covers router and modem power, and the backup essentials guide provides a preparation checklist. These tools support household planning; they do not predict the operator’s repair schedule or verify local electricity supply.
