Summary

Only African country with an operating commercial nuclear power plant (Koeberg Units 1 & 2, 1,860 MW net total). The 2039 grid target refers to IRP 2025's plan for 5,200 MW of *new* nuclear capacity by 2039 (cabinet-approved October 2025, potential expansion to 10,000 MW) — separate from existing Koeberg operations. Koeberg licence positions: Unit 1 extended to 21 July 2044 (granted July 2024), Unit 2 extended to 9 November 2045 (granted November 2025). Strong SME base and PBMR legacy. Procurement route for new build not yet finalised.
