Eskom has reassured South Africans that there will be no immediate load shedding, despite Koeberg Nuclear Power Station’s Unit 2 tripping and being taken offline. The unexpected shutdown occurred during work on Unit 1, which has been offline for maintenance as part of the Long-Term Operation (LTO) program.
While the trip has not triggered rolling blackouts, Eskom acknowledges that generation capacity remains constrained. The power utility continues to focus on maintenance to enhance the reliability of its electricity generation fleet, particularly in preparation for increased winter demand.

Koeberg Unit 2 Shutdown: What Happened?
Unit 2 of the Koeberg Nuclear Power Station—located in Cape Town—inadvertently tripped while work was being conducted on Unit 1. Eskom has assured the public that Unit 2 was safely shut down in line with standard protection protocols to maintain stability and security.
Despite the temporary loss of this unit, load shedding remains suspended, and Eskom expects to reconnect Unit 2 to the national grid within 48 hours.
Eskom spokesperson Daphne Mokwena confirmed that:
“While the trip did not necessitate the implementation of load shedding, which remains suspended, Eskom acknowledges that overall, generation capacity remains constrained.”
The power utility remains committed to improving its generation performance and preventing power cuts by maintaining high levels of scheduled maintenance.
Load Shedding: What Does This Mean for South Africa?
South Africans have been experiencing a reprieve from load shedding due to improved generation performance, increased maintenance, and higher energy availability. However, Eskom warns that the power grid remains fragile, and any further unexpected breakdowns could lead to renewed rolling blackouts.
Current electricity supply situation:
- Eskom has maintained an average maintenance level of 7,032MW in February.
- The suspension of load shedding is expected to continue, but electricity users are urged to use power responsibly.
- Eskom is preparing for higher electricity demand in winter, ensuring power stations operate at optimal levels.
While the situation is stable for now, continued investment in infrastructure and proactive maintenance will be crucial in keeping load shedding at bay.
Koeberg’s Role in South Africa’s Energy Supply
The Koeberg Nuclear Power Station is a vital component of South Africa’s electricity supply, providing 5% of the country’s total power generation. It consists of two units (Unit 1 and Unit 2), both of which contribute significantly to reducing the risk of load shedding.
Unit 2’s Recent Maintenance and Future Plans
- Unit 2 was last taken offline in December 2023 for refueling, maintenance, and the replacement of its three steam generators.
- This maintenance followed a similar 11-month outage for Unit 1, which began in mid-December 2022.
- The National Nuclear Regulator (NNR) is expected to review and decide on extending Unit 2’s operational license in 2025.
Unit 1’s Reliability
Unit 1, which contributes 930MW to the national grid, has shown exceptional reliability since its return to service. Eskom remains optimistic that both units will continue to play a key role in ensuring energy stability.
Concerns Over Structural Issues at Koeberg
While Eskom has been working hard to extend Koeberg’s lifespan, concerns over structural integrity remain. Over the past 40 years, significant cracks have appeared in the containment buildings that house the nuclear reactors.
To address safety concerns, Eskom has been conducting overpressure tests to:
- Ensure no radiation leaks occur in the event of an accident.
- Identify and repair any cracks or leakages in the structure.
These measures are critical to maintaining Koeberg’s safety and operational efficiency.
The Future of South Africa’s Electricity Supply
Eskom remains committed to:
✅ Preventing load shedding by maintaining a stable electricity grid.
✅ Enhancing power generation capacity through maintenance and upgrades.
✅ Extending the lifespan of Koeberg Nuclear Power Station to ensure reliable energy supply.
While the situation is currently under control, South Africans are urged to remain energy-conscious and continue using electricity efficiently.
