Matshela Koko, the former head of generation at Eskom, told the state capture commission of inquiry that there was nothing wrong with a controversial R1.68 billion pre-payment which the power utility made to Gupta-owned Tegeta Exploration and Resources after the company clinched a coal supply deal in 2015. “I would testify here that there is absolutely nothing wrong with the transaction of the R1.68 billion pre-payment. In fact, it was the only alternative available to Eskom,” Koko said on Tuesday, without explaining the importance of the payment.
