Residents across multiple Johannesburg regions face scheduled electricity interruptions from 18 to 24 May 2026.
This comes as City Power rolls out network maintenance work aimed at reducing the risk of unplanned outages.
Why City Power is cutting power this week
Isaac Mangena, the utility’s spokesperson, confirmed that the work is essential to the long-term health of the city’s electricity grid.
“The planned interruptions form part of ongoing work to strengthen, maintain and improve the reliability and stability of the electricity network,” Mangena said.
He added that the timing of the maintenance is particularly significant given current weather conditions.
“These maintenance activities also assist in protecting the network during periods of high demand, especially as colder weather conditions place additional pressure on electricity infrastructure,” explained Mangena.
What residents need to know before the power goes off
City Power has urged all affected customers to take precautions during the interruption periods.
“Customers are advised to treat all electricity supply points as live at all times during the interruption period, as supply may be restored earlier than anticipated,” Mangena said.
Residents have also been cautioned against leaving appliances plugged in.
Mangena said this was to “avoid possible damage when power is restored”.
