On 22 July 2022, Unit 2 suffered a fire caused by a leaking fuel oil supply/return pipeline.

In mid-December 2022, at the request of the Minister of Public Enterprises, Pravin Gordhan, and President Cyril Ramaphosa, Minister of Defence Thandi Modise deployed a small contingent of SANDF troops at the station (besides at Camden, Majuba and Tutuka) to curb growing threats of sabotage, theft, vandalism, and corruption.
