A report leaked to the media apparently shows that Eskom spokesperson Khulani Qoma accused the power utility's board of ignoring serious allegations of state capture.
According to eNCA, Qoma admitted to drawing up the report but would not confirm any details.
"Unfortunately I will not be in a position to comment further on the content of the report because it's an internal document and it's clear that the story is the consequence of a leak because we did not release a report in an official way. I wrote the report, that I'm not denying, I would not be able to comment further on the content of the report," Qoma said.
Qoma apparently compiled the report, which was meant only to be seen internally, which also urged the board to distance itself from disgraced chief executive officers Brian Molefe and Matshela Koko. Qoma also raised the issue of the organization being perceived to be arrogant in the report.
The document was reportedly submitted to the board in June, and was followed by an unsuccessful bid to have him fired.
The power utility is currently appearing before a Parliamentary committee investigating claims of corruption related to the Gupta-linked consultancy firm Trillian.
Last month, Eskom admitted to lying about payments made to the firm which were worth more than R1 billion.
