Eskom has confirmed that technicians have been dispatched to restore electricity in Pimville and Klipspruit, following a power outage that affected Zones 5 and 6 of Pimville.
UPDATE: Eskom has issued an update on the situation in Pimville. See details below:
“Due to the nature of the fault and the cable repair work being conducted on site, it is taking longer than anticipated to restore supply to Klipspruit, Pimville Zones 5 and 6. The ETR is 16:00 We apologise for the inconvenience.”
What Eskom said about the Pimville power outage
The utility did not provide an estimated time for when power would be restored.
This marks the second outage to hit the Gauteng suburb in less than a week.
On Tuesday, 4 June 2025, residents in Zones 1, 2, and 3 experienced a blackout that, according to community members, began the night before at around 11:30 PM and lasted approximately 15 hours.
Ward 22 councillor Sebenzile Mabuza confirmed that the earlier outage was caused by a power trip.
“The Technical Support Unit is currently on site to address the issue,” Mabuza said at the time.
Power trips can happen when there is a sudden fault or overload in the electricity network.
These faults can include things like damaged cables, overloaded transformers, or illegal electricity connections, all of which can cause the power to automatically shut off to prevent further damage.
Eskom’s national grid — the system responsible for generating and distributing electricity across the country — is currently described as “stable but constrained.”
This means that while the electricity supply is mostly steady, there isn’t a lot of extra electricity available to deal with unexpected problems. In simple terms, there’s enough power to go around under normal conditions, but there’s not much room for error if something breaks down or demand increases suddenly.
According to Eskom, the current focus is on bringing back power units that have been undergoing maintenance.
The utility reported that more than 2 500 megawatts (MW) of electricity generation capacity is expected to return to service by Monday evening, 9 June 2025. To explain, 1 MW can power around 650 average homes, so this amount can support millions of households.
The energy availability factor — which measures how much of Eskom’s total power-generating equipment is working — is currently fluctuating between 61% and 64%.
That means nearly four out of every ten power-generating units are either broken or under maintenance.
Eskom also continues to reduce its use of diesel-powered emergency generators, which are expensive to run and only used when other systems fail.
Unplanned outages, which refer to breakdowns or faults that were not scheduled, are still a concern.
From 30 May to 5 June 2025, Eskom reported an average of 14 644MW of unplanned outages, well above its preferred limit of 13 000MW. If unplanned outages continue to increase, Eskom has indicated that loadshedding could return, although it is currently suspended.
The utility has warned that illegal connections and overuse of electricity, especially during the cold winter months, can damage transformers and lead to further outages.
