For South Africa to be energy secure by 2032, it needs to bring 53 GW of electricity into the energy system, which, in turn, requires 14 000 km of new transmission lines to be built in a decade.
The current transmission building capacity, however, is about 400 km/y, Stellenbosch University Centre for Sustainability Transitions junior researcher Alboricah Rathupetsane pointed out this week.
