A South African case study on transformer procurement process optimization for a constrained global supply chain value

The National Transmission Company South Africa (NTCSA), formerly Eskom Transmission has a long history of transformer procurement shaped by evolving market conditions and legacy supplier relationships. Historically, the organization relied on a small pool of long-standing international transformer suppliers, model that was effective for many years. However, the recent surge in transformer demand driven largely by renewable energy integration and grid strengthening projects resulted in factory slot shortages and extended manufacturing lead times.
