The Sunday Times has reported that the stepdaughter of Eskom boss Matshela Koko received contracts for her company worth R1 billion from Eskom.

The report stated that Koketso Choma was appointed as a director at Impulse International in April 2016, after which it received eight contracts from the division of Eskom which Koko headed up.

Koko was appointed Eskom acting CEO in December.

Impulse International – an engineering and project management company – has received R1.8 billion in total deals from Eskom, stated the report. R1 billion in contracts came after Choma was a director at the company.

26-year-old Choma has since resigned from the position. Koko said he only found out that Choma worked for Impulse four weeks ago.

The report stated that Koko was also named in the public protector’s state capture report for authorising a payment of R600 million to the Gupta-owned Tegeta.

The news comes after National Treasury warned that Eskom’s delay in signing power purchase agreements with renewable energy independent power producers – whose bids were approved by the Department of Energy – could result in manufacturers going out of business.
