Northcliff power outage: four load centres await fault testing
City Power reports four remaining load centres in the outage affecting Northcliff, Blackheath and Berario in Johannesburg. Its 19:00 South African time update on 6 October schedules the test branch for the following morning to locate the fault. This is a testing plan, rather than a restoration deadline.

What the operator has reported
In its morning notice, City Power named Northcliff, Blackheath and Berario and said operators were on site investigating the cause. It said an estimated restoration time would be shared after the investigation. The notice described the outage as reported the previous night. A later notice used the wording earlier today, so the precise onset remains unresolved.
At 13:48 SAST, City Power reported approximately 80% of customers restored following a cable fault. That percentage belongs to the earlier update and refers to customers in the named affected areas. The operator did not supply an absolute customer total or explain the denominator or calculation. Arrangements for a testing team were under way; the remaining cable fault needed to be located and exposed before repairs, with no restoration estimate supplied.

What the evening update changes
The outage record concerns Roosevelt Substation and the Blackheath Distributor in the three named Johannesburg areas. It does not establish a citywide power outage, nor does a percentage show the supply status at any individual address. No independent connection-by-connection restoration check is available in the scanner record.
At 19:00 SAST, the operator reported four remaining load centres and scheduled the test branch for the morning of 7 October to locate the fault. Their identities and the affected customer count are not supplied. The testing appointment cannot be treated as a promise that electricity will return that morning. The earlier 80% figure was not remeasured in this update, and full restoration remains unconfirmed.
