Eskom is being investigated over what the government says are breaches in environmental rules by the state power utility.

“We have started investigations into certain individuals at Eskom,” Frances Craigie, a director of enforcement at the Department of Environmental Affairs, said.

In one example, Eskom's Camden power station east of Johannesburg broke air and water pollution guidelines, she said.

The department would investigate possible criminality by some Eskom employees, Craigie said, declining to elaborate.

Eskom spokeswoman Hilary Joffe said on Friday that many issues at Camden had been fixed and others needed to be addressed through longer-term projects.

The company had yet to review an enforcement report released by the department, Joffe said. - Bloomberg
