Power Utility, Eskom said the power system remains stable, as Unit 1 of Mpumalanga’s Kusile Power Station returned to service.
According to Eskom, the unit is expected to contribute an estimated 800MW back to the national grid.
“Kusile Unit 1 officially back online following its successful reconnection to the repaired flue gas desulphurisation (FGD) system and permanent stack, which had been out of service since 31 May 2025.
Once it reaches full capacity, the station will deliver its total combined output of 4 800MW to the national grid”, said Eskom in a statement.
The power utility continued to characterise this as a demonstration of resilience.
Eskom sought to guarantee that its earlier communicated 2025 Winter Outlook, which forecasts a no loadshedding winter period but does not rule out the possibility of lower stages in unforeseen circumstances, remains in place.
“It indicates that load shedding will not be necessary if unplanned outages stay below 13 000MW.
If outages rise to 15 000MW, load shedding would be limited to a maximum of 21 days out of 153 days and restricted to Stage 2,” Eskom reiterated.
As the electricity demand is expected to rise in winter, the public is urged to avoid and report illegal electricity connections.
Eskom warned that this may cause system overloads, explosions, equipment failures and extended outages which might necessitate the implementation of load reduction to protect the network.
