City Power, suspended its chief executive officer Mongezi Ntsokolo in connection with alleged impropriety and findings against him in 2018 while he was employed by Eskom.
Ntsokolo reportedly failed to declare allegations of maladministration and corruption from three years ago.
City Power spokesperson Isaac Mangena said an investigation into the allegation will be carried out in due course, but he said he could not comment on the allegations at this stage.
Eskom informed Ntsokolo at the time that he was implicated in serious acts of misconduct, including his failure to declare a personal relationship with the owner of Uphill Transport Ltd, Mpumi Phike.
He also failed to declare his relationship to other entities in business with Eskom Holdings.
Ntsokolo was employed by Eskom for 27 years and was retrenched in December 2018 - just one day after receiving a letter from then group chief executive Phakamani Hadebe that he had to respond to allegations of serious misconduct in flouting Eskom’s conflict and declaration of interests policies.
At the time of his appointment, City Power board chairperson Lindiwe Maseko said Ntsokolo’s appointment as CEO would bring stability to the power utility.
