South Africa: NNR Extends Koeberg Nuclear Power Station Unit 2 Licence To 2045

South Africa’s National Nuclear Regulator (NNR) has approved a 20-year licence extension for Eskom’s Koeberg Nuclear Power Station Unit 2, allowing it to continue operating until 2045.

Koeberg Nuclear Power Station Unit 2 marks 40 years of safe, clean, and reliable operation, reaffirming South Africa’s capability to manage world-class nuclear facilities and deliver affordable, low-carbon electricity to the nation.

This follows a similar approval granted for Unit 1 in 2024.

Since entering commercial operation on 9 November 1985, Unit 2 has been a cornerstone of South Africa’s energy system—providing dependable baseload power, enhancing grid stability, and supporting economic growth in the Western Cape and beyond.

With both Units 1 and 2 now extended for an additional 20 years, they will together supply approximately 1,860 MW of clean, reliable, and affordable power to the national grid for the next two decades—supporting the goals of the Integrated Resource Plan (IRP) 2025 and South Africa’s just energy transition.

“Koeberg’s 40-year milestone is a proud moment for South Africa and proof of our ability to operate complex infrastructure safely and sustainably. With both units now licensed for another 20 years, Koeberg remains a cornerstone of our energy security and a key contributor to the clean energy transition under IRP 2025,” Eskom’s Group Chief Executive, Dan Marokane, said in a statement on Sunday.

Commenting on the achievement, Eskom’s Group Executive for Generation, Bheki Nxumalo, said:
“Koeberg’s success over the past four decades is driven by the exceptional dedication, professionalism, and expertise of its employees—men and women whose commitment ensures safe, reliable operations every day.

“Their work keeps the lights on for millions of South Africans. Koeberg’s consistent performance continues to demonstrate operational excellence, environmental stewardship, and the value of investing in South African skills and capability.”

Koeberg Unit 2, which currently contributes 946 MW to the grid, achieved a 100% Energy Availability Factor (EAF) for 244 consecutive days this year, reflecting world-class reliability.

The station has also received more than 14 NOSCAR safety awards from the National Occupational Safety Association (NOSA), underscoring its strong culture of safety and discipline.

Located near Cape Town, Koeberg reduces transmission losses, supports regional energy needs, and operates within a 3,000-hectare nature reserve—highlighting Eskom’s commitment to sustainability and environmental preservation.
