President Cyril Ramaphosa has reaffirmed government's commitment to unbundling Eskom by backing the creation of an independent transmission system operator, despite resistance from within the utility. The move is intended to create a more competitive electricity market and expand grid capacity, but concerns remain over Eskom's financial sustainability, the loss of transmission assets and the growing burden of municipal debt. Energy analyst Professor Sampson Mamphweli explains what these reforms could mean for South Africa's power sector and electricity consumers.
