Koeberg Nuclear Power Station’s Unit 1 is offline.
Eskom confirmed that a turbine which tripped, in the early hours of Thursday morning, was the reason for taking it offline.
Daphne Mokwena, Eskom’s Spokesperson, said all plant monitoring confirmed that operating conditions remained stable throughout the event.
“Nuclear safety was never compromised and there was no risk to employees, the public, or the environment. Koeberg’s protection and monitoring systems functioned as designed, ensuring the unit always remained safe” she said.
She also said the removal of the unit, will not compromise capacity.
Koeberg’s Unit 1 was last taken offline for major maintenance, completed in October 2025.
The cause of the turbine trip is currently under investigation.
