Mabuza has been appointed by Ramaphosa to lead a task team on the sustainability and turnaround of Eskom.
“We're pleased by the progress we're making, better transforming and improving the performance of Eskom under the leadership of the new CEO,” he said.
“The timeline can be up to 2022. We hope by that time we'll have completed the restructuring of the whole entity, dividing into three entities.”
Mabuza then moved to apologise to the country for Eskom's ongoing load-shedding, which on Wednesday suddenly moved from stage 2 to stage 4, meaning residents and the economy could now experience power cuts up to three times a day.
“We must apologise for the continued disruptions in terms of energy supply. This is because of our maintenance challenges. Our people and honourable members will understand that we're dealing with a very old fleet and from time to time it presents operational problems,” he said.
“We're confident with the introduction of Medupi and Kusile into the grid — I think Medupi would be operational at the end of the year, if everything goes well — gradually it will reduce pressure on the generation of electricity.”
