Business Unity South Africa (Busa) has expressed concern that the Eskom unbundling plan announced in December might represent a “major setback” for the reforms under way in the electricity sector and is seeking urgent clarity as to why the policymaker has endorsed the plan. CEO Khulekani Mathe tells Engineering News that organised business was taken by surprise by the announcement that the National Transmission Company South Africa would remain an Eskom Holdings subsidiary and that the transmission assets would not be transferred to a new Transmission System Operator (TSO) being set up outside of Eskom.
