Cape Town – On New Year’s Eve, Eskom announced the successful synchronization of Unit 2 from the Koeberg Nuclear Power Station in Cape Town with the national grid.
Eskom highlighted that this significant milestone in the Generation Operational Recovery Plan and South Africa’s pursuit of a reliable, cost-effective, and environmentally sustainable energy supply was achieved on Monday, (30 December 2024).
“This achievement follows a comprehensive Long-Term Operation (LTO) program designed to extend Unit 2’s operational lifespan by an additional 20 years,” Eskom reported in a press release shared with The Bulrushes.
“The maintenance work for Unit 2 included the replacement of three steam generators, in-depth inspections, and refueling efforts to ensure ongoing safe and effective reactor performance.
“These enhancements are part of Eskom’s wider strategy to secure the future viability of Koeberg’s reactors, which are vital for the country’s energy security.”
Contributing 930MW, Unit 2 is essential to Eskom’s goal of increasing its capacity by 2,500MW by March 2025, as the utility clarified.
The National Nuclear Regulator is anticipated to make a decision regarding the extension of Unit 2’s operational license in 2025.
This comes after the successful renewal of Unit 1’s license, which now allows operation until 2044.
Unit 1, also providing 930MW to the grid, has shown exceptional reliability since its return to service.
“Collectively, Units 1 and 2 will provide 1,860MW – nearly 5% of South Africa’s total electricity – playing a crucial part in mitigating load-shedding and stabilizing the grid,” the statement said.
Celebrating 40 years of safe and efficient operations in 2024, Koeberg Nuclear Power Station remains a cornerstone of Eskom’s energy framework.
“The successful completion of Unit 1’s LTO program in 2023 has set the stage for similar upgrades with Unit 2, further solidifying Koeberg’s critical role in South Africa’s energy landscape,” Eskom stated.
“Unit 1 has consistently delivered outstanding performance, and Unit 2 is expected to match or exceed these achievements.”
The power utility underscored that Koeberg’s sustained success underscores its importance in fulfilling South Africa’s energy demands and aiding the transition to a low-carbon economy.
“Through strategic collaborations with international designers, suppliers, and industry leaders, Koeberg has emerged as a hub for nuclear innovation,” remarked the Group Executive for Generation, Bheki Nxumalo.
“These partnerships are expected to be pivotal as South Africa explores advanced nuclear technologies, including Small Modular Reactors (SMRs).
“This initiative could position the country as a leader in cutting-edge nuclear solutions while also cultivating a skilled nuclear workforce.”
Nxumalo further emphasized: “As South Africa moves to phase out some aging coal-fired power plants by 2030, nuclear energy is positioned to offer a reliable and stable baseload power supply.
“Unlike intermittent renewable energy sources, nuclear power guarantees uninterrupted electricity generation to meet the needs of both residential and industrial consumers.
“Its ability to produce carbon-free energy also supports South Africa’s climate goals by reducing greenhouse gas emissions.”
Eskom expressed its expectation for Koeberg’s enhanced performance to be fully realized in FY26, highlighting Unit 2’s record of 498 consecutive days of operation and a 93% energy availability factor as benchmarks for future reliability.
“These accomplishments demonstrate Koeberg’s potential to effectively address South Africa’s energy challenges,” Eskom added.
