Power utility Eskom has confirmed that an explosion occurred at unit 4 of Medupi power station on Saturday night.
While no injuries have been reported, emergency services attended to seven employees for shock. All employees and contractors have been accounted for, said Eskom.
The incident is thought to have caused unit 5 to trip.
In a statement on Sunday morning, Eskom said the explosion took place at 22:50 on Saturday.
It said that the area had been cordoned off following the blast. Once it has been declared safe, inspections will start to try and ascertain the cause of the explosion.
