On Sunday, 3 November 2024, at approximately 17:04, Unit 6 at Kriel Power Station correctly tripped following the loss of hydraulic oil to the turbine valves. A preliminary investigation revealed that an oil pipe had broken, causing an oil spill on the hot surfaces of the turbine, which triggered a fire.
Eskom assures South Africans that this incident will not impact the current generation capacity or lead to loadshedding. The ongoing, incremental results of the Generation Recovery Plan have continually added more of a “buffer” to the system to manage incidents such as this. The system has sufficient reserves.
The station’s fire and emergency team responded swiftly to extinguish and contain the fire. Eskom can confirm no personnel were injured, and all other units at the power station remain fully operational. The standard investigation procedure is now underway to assess the extent of the damage, as well as the time required for repairs and restoration. Eskom will make a further announcement when the results of this investigation are finalised.
Impact on Power Supply:
Kriel Power Station Unit 6 contributes 475MW to the power grid. With this unit temporarily offline, total unplanned outages stand at 8 483MW—still 4 517MW below the base case for summer 2024.
The current available generation capacity is 30 809MW, while today’s peak demand is forecasted at 26 364MW. There are currently adequate reserves for evening peak, with an additional 720MW anticipated to return to service later today, Monday 4 November 2024.
Eskom remains committed to maintaining a reliable power supply and will continue to provide the public with significant updates.
