Cape Town nuclear plant, which began operation in 1985, could now be online until 2045
South Africa’s state power company Eskom has Eskom successfully synchronised Unit 2 of the Koeberg nuclear power station in Cape Town to the national grid on 30 December following an extensive long-term operation programme designed to extend the plant’s operational lifespan by an additional 20 years to 2045.
Eskom said the maintenance programme for Unit 2 included the replacement of three steam generators, comprehensive inspections, and refuelling activities.
The company said the programme aligns with its broader strategy to secure the future of Koeberg’s two reactors, which are critical to the country’s energy security.
South Africa’s nuclear regulator is anticipated to decide on the extension of Unit 2’s operational licence in 2025.
This comes after the renewal of Unit 1’s licence, which extends its operation until 2044.
Koeberg-1 began commercial operation in 1984 and Koeberg-2 in 1985. Both are pressurised water reactor units and according to Eskom have a combined capacity of 1,860 MW.
Nuclear energy provided about 5% of South Africa’s electricity generation in 2023, according to International Atomic Energy Agency data.
Koeberg is South Africa’s only commercial nuclear power station and the only such facility in Africa, although Russia is building a new nuclear station in Egypt.
Nuclear Plans Include Small Modular Reactors
South Africa’s electricity minister Kgosientsho Ramokgopa announced in December 2023 that Pretoria would begin a procurement process for an additional 2,500 MW of nuclear power capacity to tackle blackouts that have crippled the nation.
Earlier this year Ramokgopa said the procurement process for planned new nuclear in South Africa could be delayed by up to six months to allow for more consultation following legal challenges.
Eskom increased power cuts to record levels in 2023 as its fleet of coal stations struggled with constant breakdowns and plant malfunctions triggered by age, poor maintenance and corruption.
Eskom group executive for generation, Bheki Nxumalo, said South Africa is exploring advanced nuclear technologies such as small modular reactors. “This could position the country as a leader in cutting-edge nuclear solutions while continuing to build and maintain a skilled nuclear workforce,” he said.
