Cape Town – On New Year’s Eve, Eskom announced that Unit 2 of the Koeberg Nuclear Power Station in Cape Town has successfully been synchronized with the national grid.

The utility highlighted that this significant achievement in the Generation Operational Recovery Plan marks a step forward in South Africa’s pursuit of a dependable, economical, and environmentally friendly energy supply, reached on Monday, (30 December 2024).

Eskom mentioned in a press release shared with The Bulrushes that “This accomplishment followed a thorough Long-Term Operation (LTO) program aimed at extending Unit 2’s operational lifespan by an added 20 years.”

“Maintenance efforts for Unit 2 included the replacement of three steam generators, extensive inspections, and refueling measures to ensure the reactor operates safely and efficiently.”

“These enhancements are part of Eskom’s comprehensive strategy to ensure the long-term sustainability of Koeberg’s reactors, which are vital for the energy security of the country.”

With a 930MW contribution, Unit 2 plays a crucial role in Eskom’s plan to boost its capacity by 2,500MW by March 2025, as the utility explained.

The National Nuclear Regulator is anticipated to make a decision in 2025 regarding the extension of Unit 2’s operational license.

This decision follows the successful renewal of Unit 1’s license, which now allows operations until 2044.

Unit 1, which also contributes 930MW to the grid, has exhibited exceptional reliability since it returned to service.

“With both Units 1 and 2 together contributing 1,860MW – nearly 5% of South Africa’s total electricity – they play an essential part in reducing load-shedding and stabilizing the grid,” the statement indicated.

Koeberg Nuclear Power Station, celebrating 40 years of safe and efficient operations in 2024, remains a cornerstone of Eskom’s energy strategy.

“The successful completion of Unit 1’s LTO program in 2023 has set the stage for similar advancements with Unit 2, further solidifying Koeberg’s critical role in South Africa’s energy future,” Eskom noted.

“Unit 1 has shown remarkable performance, and it is expected that Unit 2 will meet or exceed these standards.”

Eskom emphasized that Koeberg’s continued success underscores its significance in meeting South Africa’s energy needs and aiding the transition to a low-carbon economy.

“Through strategic partnerships with international designers, suppliers, and industry experts, Koeberg has become a hub for nuclear innovation,” stated Bheki Nxumalo, Group Executive for Generation.

“These collaborations are crucial as South Africa explores advanced nuclear technologies, including Small Modular Reactors (SMRs).

“Such advancements could position the country as a leader in cutting-edge nuclear solutions while fostering a skilled nuclear workforce.”

Moreover, Nxumalo added: “As South Africa phases out some of its aging coal-fired power plants by 2030, nuclear energy is set to provide a reliable and stable baseload power supply.

“In contrast to variable renewable energy sources, nuclear power ensures consistent electricity generation to meet the demands of both residential and industrial consumers.

“Its ability to produce carbon-free energy also aligns with South Africa’s climate improvement goals by reducing greenhouse gas emissions.”

Eskom anticipates Koeberg’s improved performance to be fully evident in FY26, with Unit 2’s record of 498 consecutive days of operation and a 93% energy availability factor serving as a benchmark for future reliability.

“These achievements illustrate Koeberg’s capacity to effectively address South Africa’s energy challenges,” Eskom remarked.
