Local – An extension of 20 years has been granted to Eskom’s Koeberg Nuclear Power Station Unit 2, marking a significant step in strengthening South Africa’s long-term energy security.
The National Nuclear Regulator (NNR) approved the licence, allowing the unit to continue operating until 9 November 2045.
Eskom said the decision reflects confidence in the country’s nuclear capabilities and demonstrates its ongoing commitment to world-class safety and reliability standards.
“The approval marks a significant step in strengthening South Africa’s long-term energy security and reflects Eskom’s commitment to maintaining world-class nuclear safety standards,” Eskom said.
Consistent Performance and Global Standing
Unit 2 contributes around 946MW to the national grid and has maintained an energy availability factor of 100% for 241 consecutive days this year. Eskom said the plant’s performance underlines its critical role in supporting South Africa’s electricity supply.
“This consistent performance underscores the station’s critical role in supporting South Africa’s electricity supply,” the utility said.
“The licence extension follows the successful completion of an extensive refurbishment and life-extension programme, which included the replacement of three steam generators, thorough safety inspections, and refuelling activities to ensure the unit’s continued safe and efficient operation.”
Koeberg’s Unit 1 received its long-term operating licence in July 2024, extending its lifespan to 2044.
With both units now licensed for extended operation, Koeberg joins more than 120 nuclear reactors worldwide that have safely surpassed their original 40-year design life.
“Together, both units are now part of a global cohort of more than 120 nuclear reactors that have safely extended their service beyond the original 40-year design life – affirming Koeberg’s place among the world’s most resilient and well-managed nuclear facilities,” Eskom said.
“This achievement supports South Africa’s broader energy planning objectives, including the Integrated Resource Plan [IRP2025], which recognises the role of nuclear energy in delivering low-carbon, cost-effective, and dependable baseload power.”
Investing in Nuclear Expertise
Eskom’s Chief Nuclear Officer, Velaphi Ntuli, said the milestone was the result of hard work, dedication, and collaboration across the company and the wider nuclear value chain.
He emphasised that the process showcased South Africa’s strong engineering base and commitment to developing nuclear expertise.
“The rigorous safety assessments and regulatory requirements Eskom had to meet to achieve the long-term operation demonstrate the depth and pipeline of nuclear engineering talent available in South Africa that delivers high-quality jobs,” Ntuli said.
Group Chief Executive Dan Marokane said the licence extension aligns with Eskom’s drive to strengthen energy security and transition to a cleaner power generation mix.
“Koeberg and Eskom’s nuclear power expertise will play a key role as we move aggressively into delivering a cleaner energy portfolio and moving from high-carbon to low-carbon sources of electricity generation,” Marokane said.
“With Koeberg providing more vital baseload power, it further forms the backbone for renewable energy growth and integration into the grid to maintain grid stability and supply.”
