Affected addresses and recovery time unknown
Heriotdale Extension 10 is the affected area named by City Power. The statement provides neither a customer count nor a complete address list, so it cannot establish that every property in the extension is without power. Naming Cleveland Substation and the Marathon Distributor does not establish an outage throughout Cleveland or across Johannesburg.
The available evidence is one primary operator statement, without independent confirmation of the current position at individual addresses. No completed restoration is recorded. The notice concerns this specific distributor and extension on 30 October; a connection with earlier Cleveland-area interruptions has not been established. Their causes, repair histories and timings cannot be transferred to this incident simply because a substation name is shared.
