Description

Koeberg Nuclear Power Station near Cape Town contributes approximately 1,800 MW to South Africa's grid — roughly 4–5% of national capacity — and is the only nuclear plant on the African continent. Eskom applied to NERSA for a 20-year life extension beyond the original 2024 decommissioning date. Unit 1's life extension was approved following steam generator replacement (a major technical milestone completed in 2023–24). Unit 2 life extension approval is pending regulatory review. Koeberg's continued operation is significant for Western Cape grid stability, providing reliable baseload generation that wind and solar cannot replicate without storage. The life extension avoids decommissioning costs of R20+ billion and preserves 1,800 MW of zero-carbon baseload capacity. As of early 2026, Unit 1 has returned to service under extended licence; Unit 2 steam generator replacement is scheduled, with full dual-unit extended operation expected by 2025–26.

Assessment

Growth Impact4/5

Feasibility Assessment

High: NNR licence extension granted; steam generators installed. Operational risk is ongoing maintenance and fuel procurement. Fiscally positive — avoids costly replacement capacity.

Implementation Roadmap

The Koeberg long-term operation (LTO) extension secures 1,860 MW of baseload zero-carbon generation through at least 2044, providing critical system stability during the transition to renewables. The NNR granted the safety case for LTO in 2023 following Eskom's Periodic Safety Review submission; steam generator replacement for both units was completed in 2023–24. Implementation now focuses on the continuous ageing management programme, regulatory reporting obligations, workforce retention, and spent fuel management for the extended operating period. This is the lowest-cost firm low-carbon generation option available to South Africa in the near term, with a projected LCOE below R1.20/kWh.

Timeline

NNR LTO approval granted 2023; ongoing ageing management through 2044; fuel supply agreement Q3 2025; spent fuel facility expansion Q4 2026

Estimated Cost

Steam generator replacement: R25 billion (Eskom capital, substantially complete). Ongoing LTO ageing management: ~R800 million/year. Spent fuel storage expansion: ~R2 billion (2025–2026). Total LTO programme cost ~R43 billion to 2044 vs. R150–200 billion for equivalent new-build replacement.

Required Legislation

No new primary legislation required. NNR Act 47 of 1999 and Nuclear Energy Act 46 of 1999 provide the complete framework. The NNR operating licence constitutes the operative regulatory instrument.

Political Feasibility

Broad support: Koeberg is the only operating nuclear station and LTO avoids a 1,860 MW capacity gap during a grid crisis. ANC, DA, and most GNU parties support it on energy security grounds. Environmental NGOs (Earthlife Africa, groundWork) maintain principled opposition but have not challenged the LTO licence in court.

International Precedents

France's EDF has operated LTO programmes across its 56-reactor fleet, extending plant lives to 60 years — the global model. The US NRC has granted 20-year LTO extensions to over 80 reactors. Finland's Loviisa NPP operates under a similar safety case framework and provides a directly applicable small-fleet precedent.
