Summary

In this episode of Energy Conversations, host Tugo Zile Zibani interviews Keith Bowen, Senior Manager Market Operator at the National Transmission Company of South Africa (NTCSA), about the ongoing restructuring of South Africa’s electricity market. Bowen explains that the market is already evolving with increased competition, particularly from rooftop solar and private generators. He defines the wholesale market as focusing on large-scale supply and demand, involving bulk suppliers and large power users like Sasol and Anglo American. The role of the market operator is to coordinate transactions that underpin the physical flow of electricity, ensuring that generators and customers are balanced. The conversation covers the recent changes, including the lifting of licensing thresholds, which has led to a significant increase in wheeling capacity from 10-20 MW to over 800 MW in 18 months. Bowen discusses the upcoming implementation of a day-ahead market and balancing mechanism, which will make generators balance responsible. He also addresses the implications for ordinary South Africans, touching on reliability, affordability, and the need for tariff reform to protect captive customers and ensure grid sustainability. The episode highlights the need for new skills in energy trading, risk management, and data analysis, and outlines the next 12-24 months’ milestones, including opening the market to external participants.
