Koeberg Nuclear Power Plant Long-Term Operation Extension
Theme: Nuclear energy
Assessment
Responsible: Department of Mineral Resources and Energy / Eskom / NNR / NERSA
Feasibility Assessment
High: NNR licence extension granted; steam generators installed. Operational risk is ongoing maintenance and fuel procurement. Fiscally positive — avoids costly replacement capacity.

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. EskomEskom: South Africa's national electricity utility and dominant power producer, transmitter, and distributor. Eskom's debt crisis and maintenance failures have been a primary cause of load shedding and a binding constraint on economic growth. applied to NERSANERSA — National Energy Regulator of South Africa: The regulatory authority for the electricity, piped-gas, and petroleum pipelines industries in South Africa. NERSA approves Eskom's tariff applications and licenses new electricity generators. 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.

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.
Complete Unit 1 and Unit 2 steam generator replacement and submit Periodic Safety Review (PSR) documentation to the NNR for the extended operating period to 2044
Implement the Ageing Management Programme (AMP): annual inspections of reactor pressure vessels, primary circuit components, and civil structures; quarterly reporting to NNR as required by operating licence conditions
Negotiate and sign the long-term fuel supply agreement with a qualified nuclear fuel supplier (Framatome/Westinghouse/TVEL) covering enrichment, fabrication, and delivery for 20 years of extended operations
Evidence & Research
Research corpus →- The labour market effects of South Africa’s electricity crisis
UNU-WIDER · Jan 2026
The paper quantifies the labour market damage from electricity supply shortfalls and demonstrates that reliable baseload generation (via Cape Town's outage mitigation) recovers employment; Koeberg's life extension directly addresses South Africa's electricity reliability crisis by preserving 1,800…
- Coal, weather shocks, and electricity reliability: Evidence from South Africa
SA-TIED
The paper analyses electricity reliability constraints and supply-chain vulnerabilities in South Africa's power system; evidence on coal's weather-driven unreliability directly supports the case for Koeberg's continued operation as reliable baseload generation that avoids such disruptions.
- Firm Adaptation and Reallocation under Rationing: Evidence from South Africa Working paper 932
ERSA · May 2026
The paper studies how power rationing affects firm revenues and adaptation during South Africa's 2021-2023 power crisis, providing evidence on the economic consequences of electricity supply constraints that the Koeberg extension directly addresses by maintaining baseload generation capacity.
