Brian Molefe has been appointed as acting CEO of Eskom, Public Enterprises Minister Lynne Brown said on Friday.
Brown said the appointment of Molefe as a 'permanent' acting CEO was meant to address leadership issues at the power utility.
"I needed to stabilise leadership both at Eskom executive management and board [level] so I had to make this appointment," said Brown.
"The suspension of Eskom's executives and the inquiry has created uncertainty."

Molefe, currently group CEO of Transnet, stated that his first priority is to minimise load shedding.
"My immediate agenda is to minimise load shedding and ensure that going forward, we move away from the heavy reliance on coal for our energy needs," he said.
Molefe added that South Africa currently generates 85 per cent of its power from coal-fired power stations.
"We have 200 years of coal in our country, in the short term we need to use it to generate more power but systematically reduce our reliance going forward," he added.
Brown stated that an acting CEO for Transnet would be announced on Monday.
