City Power offices in Johannesburg.
Johannesburg City Power has placed Thabang Mashishi, a manager in the Supply Chain Division, on precautionary suspension with immediate effect pending investigations.
The suspension relates to media reports and allegations lodged by a whistleblower of acts of misconduct and extortion involving current and former City Power contractors.
The utility has also confirmed that Marvin Baepi, General Manager for Research and Development, remains on suspension following a separate case previously reported against him involving similar allegations against Mashishi.
It is alleged that senior City Power officials extorted over R2 million from the whistleblower, who has been contracted to the utility for years, with payments often made in cash ranging between R100 000 and R250 000.
City Power spokesperson Isaac Mangena says, “These steps form part of our ongoing efforts to root out corruption….Over the past year, we intensified efforts to address wrongdoing and collusion. This has resulted in several dismissals and suspensions… We remain firm in our stance that there is no place for corruption and unethical conduct within City Power.”
