Public Announcement from City Power Johannesburg
A planned outage is a power interruption that occurs when City Power switches off electricity supply at a substation or other portion of the network in order to execute maintenance and /or emergency duties to correct defects in the network so that it functions at its maximum potential.
Loss of Power
A subsequent loss of power to customers as a result of a planned outage being implemented, may affect all or some of the areas/customers supplied from the substation or portion of the network concerned as in certain occasions only part of the substation may be isolated.
However it is important to note that the areas mentioned as affected in the scheduled planned outage notice document are the areas that will definitely be isolated (switched off).
