State-owned power utility Eskom says group finance GM Martin Buys will serve as acting CFO with immediate effect and until further notice.
It says Buys is a seasoned executive who started his career at Eskom in 1987.
He has held various roles over the course of his almost 40-year career at Eskom, predominantly within the field of finance.
This follows the appointment, in February, of Calib Cassiem as Eskom interim CEO, following the departure of Andre de Ruyter.
