On Saturday, 23 May 2026, the City of Tshwane’s Energy and Electricity Business Unit will switch offline 1 at 132 kV, which supplies the Waltloo and Rooiwal Substations. This is not load shedding. This is a planned, deliberate shutdown that the city’s technical services and primary distribution teams need to carry out urgent maintenance and repairs on the affected line.
The City of Tshwane describes this as a proactive measure, an action taken now to prevent much larger and costlier breakdowns in the future. The maintenance work aims to improve the reliability and long-term stability of Tshwane’s electrical network, which serves millions of residents and businesses across the city.
Which areas experience power outages and for how long
Power will switch off at 8h00 sharp and return at 18h00, a total of 10 uninterrupted hours. The following areas will be affected:
- Silverton
- Nellmapius Ext 1 & 4
- Eersterust
- Silvertondale
- East Lynne
- Queenswood
- Waverley
- Kilner Park
- Koedoespoort Industrial
- Transnet Works
If you live, work, or run a business in any of these areas, plan ahead now. Charge devices, stock up on water, and make arrangements for anything that depends on electricity, including security systems, refrigeration, and medical equipment.
The Safety Warning You Must Not Ignore
Even with the power off, danger remains. The City of Tshwane issues a firm warning to every resident and business in the affected areas:
“Customers are urged to treat all electrical installations as live throughout the duration of the interruption,” said the city.
Do not touch exposed wiring, tamper with electrical boxes, or assume any installation is safe simply because the power appears to be off. Treat every wire and every switch as energised until electricity officially returns at 18h00. This warning applies to homeowners, tenants, and workers on industrial premises equally.
How to Report a Fault or Get Help
If your power does not return after 18h00, or if you experience any electrical fault during the interruption, contact the City of Tshwane’s customer care centre immediately on 012 358 9999 and select option 3. You can also SMS the word “power” followed by your account number to 082 612 0333 or 44676. The city apologises for the inconvenience and asks for the public’s understanding as it works to keep the network running reliably.
