South Africa’s R440-billion transmission grid expansion programme has attracted interest from international developers, including a company owned by Indian billionaire Gautam Adani and Chinese firms. The continent’s most industrialised nation started up the Independent Transmission Projects program in December to bring in private partners to help install 14 000 km new power lines. The government aims to add 34 gigawatts of generating capacity from wind and 25 gigawatts from solar over the next 14 years, and will require more connections to an already constrained system.
