Jabu Mabuza, chairperson of Eskom's board, has said that the Medupi and Kusile power plants are still not generating as much energy as they were intended to.
This comes as the costs of running the plants continues to increase.
Mabuza made the comments before the Commission of Inquiry into State Capture.
Mabu explained that costs had rapidly escalated at the plants. He said that the cap for the costs for Medupi and Kusile respectively were R70 billion and R80 billion. However, he claimed that Medupi's costs were now around R120 billion, while Kusile's stood at R140 billion, according to Eyewitness News.
Reportedly, the plants require extensive maintenance and are prone to outages. There were 87 outages at the plants in 2018 alone.
Additionally, the power stations are only at 40% reliability, according to Eskom insiders, and are not producing electricity at full capacity. As a result, they have been singled out as a major contributor to Eskom's economic woes.
Medupi and Kusile are Eskom's youngest power plants, but they are still not working well enough to ease the power utility's energy problems.
The commission is expected to hear further testimony from Eskom executives like Daniel Mashigo, general manager for Primary Energy Division. They will presumably elaborate on the challenges the power utility is facing.
