Overcoming energy transmission congestion is vital to stabilise energy supply in South Africa and, to ensure that energy supply meets demand, transmission assessments and upgrades need to be conducted to allow for energy access from resource-rich solar and wind areas, states renewable-energy producer Enel Green Power (EGP RSA) country manager William Price. Energy transmission is similar to traffic, as energy can flow both ways, but the location of the transmission grid in relation to the energy supply and source of energy consumption impacts on the energy flow through the transmission line, he explains.
