The City’s Energy and Electricity Business Unit confirmed that the interruption, initially planned for Saturday, 20 June, has been rescheduled to Monday, 22 June. The delay was prompted by the Independent Electoral Commission’s voter registration activities taking place over the weekend.
“The rescheduling is due to the IEC’s voter registration activities taking place over this weekend,” the city said in a media alert issued on 19 June.
When the power outage will hit and which areas are affected
The electricity supply interruption is scheduled to run from 8:00 to 18:00 on Monday, lasting approximately 10 hours. The following areas will be without power:
- Savanna Estate
- The Blyde
- Nellmapius Extensions 6, 7, 8, and 22
- Pienaarspoort
- Kopanong (Skierlik)
Technicians will shut down electricity components at the Heatherley Substation to carry out critical infrastructure upgrades. Residents in these areas should plan accordingly, charging devices, storing water, and making alternative arrangements for heating or cooking ahead of time.
