Eskom had faced intense political pressure over the past year to keep the country's lights on, irrespective of the cost, the power utility board member Busi Mavuso told Parliament in October.
She also said load shedding needed to happen in the country because Eskom's power units are ageing.
On Thursday the power utility implemented stage 2 load shedding.
To discuss what is happening at Eskom, Bongani Bingwa chats to Standing Committee on Public Accounts (Scopa) member Alf Lees and the power utility chief operations officer Jan Oberholzer.
The immediate problem at Eskom is a product of the poor designs of the new power stations of Mudipi and Kusile, which should have been online already. These design problems are resulting in capacity problems there.— Alf Lees, Member - Scopa
He says these new power stations are operating later than they should have been.
Khusile is still not completed and even the units that are completed, they are operating around 60% efficiency because of bad design and bad workmanship.— Alf Lees, Member - Scopa
The old power stations that should have been retired are now having to need a lot of maintenance, he adds.
You have a problem where new power stations that needed to be operating at full capacity three years ago coupled with trying to compensate for that with old power stations.— Alf Lees, Member - Scopa
Oberholzer says the reason for the load shedding is because the utility is operating 13,000 MW of unplanned breakdowns.
We have lost 10 units on breakdowns and five of them being on the boiler tube leaks. We expected three of them to return last night. One returned but we lost another one. We will be implementing load shedding again this morning— Jan Oberholzer, COO - Eskom
He believes that by 6am on Saturday morning Eskom may be in a position to abandon load shedding.
