Eskom has provided further details on the distinctive roles it envisages being performed by the National Transmission Company South Africa (NTCSA) in relation to the transmission system when compared with the yet-to-be-established Transmission System Operator (TSO). Under a newly approved unbundling framework, the NTCSA is set to remain a wholly owned subsidiary of Eskom Holdings and retain ownership of the transmission system assets, while the TSO will be established as a new State-owned company outside of Eskom Holdings.
