- Eskom has announced that the National Nuclear Regulator (NNR) has granted a 20-year licence extension for Koeberg Nuclear Power Station Unit 2, allowing it to operate until 9 November 2045.
- The decision follows Eskom’s comprehensive application, which included rigorous safety assessments, technical evaluations, and infrastructure upgrades under the station’s Long-Term Operation (LTO) programme.
This milestone is seen as a major boost to South Africa’s energy security and a testament to Eskom’s adherence to global nuclear safety standards. Unit 2, currently supplying 946MW to the national grid, has shown remarkable reliability, maintaining a 100% Energy Availability Factor (EAF) for 241 consecutive days this year. The extension comes after a successful refurbishment programme involving the replacement of three steam generators, extensive safety inspections, and refuelling to ensure continued safe and efficient operation.
Unit 2 now joins Unit 1, which received its licence extension in July 2024, extending its life until 21 July 2044. Together, both units are part of a global group of over 120 nuclear reactors that have surpassed their original 40-year design life, reinforcing Koeberg’s reputation as one of the world’s most resilient nuclear facilities.
Velaphi Ntuli, Eskom’s Chief Nuclear Officer, credited the achievement to the dedication and expertise of Eskom’s workforce, highlighting the depth of nuclear engineering talent in South Africa. He emphasized the importance of continued investment in STEM education to support future nuclear capacity development aligned with the country’s integrated resource plan.
Bheki Nxumalo, Group Executive for Generation, noted that the licence extension underscores South Africa’s ability to manage complex energy infrastructure and supports the nation’s transition to a low-carbon, secure energy future. Group Chief Executive Dan Marokane added that the move is part of Eskom’s broader generation recovery plan, ensuring that national assets continue to serve socio-economic growth.
Marokane also stressed Koeberg’s role in supporting renewable energy integration by providing stable baseload power, essential for maintaining grid reliability. The extension aligns with the Integrated Resource Plan (IRP2025), which recognizes nuclear energy as a key component in delivering cost-effective, low-carbon electricity.
Koeberg Unit 2 will celebrate 40 years of safe operation on 9 November 2025. The station has earned NOSCAR safety status from the National Occupational Safety Association (NOSA) more than 14 times, reflecting its strong safety culture. Situated in the Western Cape, Koeberg contributes to regional grid stability and is surrounded by a 3,000-hectare nature reserve, demonstrating Eskom’s commitment to environmental stewardship.
Eskom expressed gratitude to the community, stakeholders, and partners for their continued support. As Koeberg enters its next phase, the utility reaffirmed its commitment to governance, operational resilience, and long-term sustainability for the benefit of South Africa and the broader region.
