The outages will take place between 08:00 and 16:00 on both days. These interruptions are part of City Power’s ongoing efforts to improve service reliability and prevent unplanned blackouts.

On Saturday, 28 June, no specific outages have been officially announced yet, but residents are advised to stay alert for updates from City Power.
Background and Reason for Outages
City Power has emphasised that these outages are necessary to maintain and upgrade Johannesburg’s electrical network. The city’s power infrastructure is ageing and under strain due to increased demand, especially during colder months when heating needs rise.
Maintenance work includes upgrading substations and switching stations to reduce the frequency of unplanned outages and improve overall power quality.
Impact on Residents and Businesses
During the outages, residents and businesses will experience complete power loss for the scheduled hours. City Power advises all affected customers to treat all electrical points as live and take precautions to ensure safety.
Residents should plan ahead by charging essential devices and storing water, as electric pumps may be affected. Businesses, particularly those relying on continuous power, should prepare backup systems or adjust operations accordingly.
