The Koeberg nuclear plant is the only nuclear power plant in Africa. Construction began in the 1970s and the plant came online in 1984. It operates under a licence from the National Nuclear Regulator (NNR) which expires in July 2024. In 2010 the Eskom Board approved spending R20bn on refurbishing Koeberg to extend its life by 20 years, provided that it received approval from the NNR. That approval has not as yet been given to Eskom by the NNR.
Currently Koeberg provides 3.5% of national nominal generating capacity, although over the past few years it has been plagued by problems. For most of 2022, unit 2 has been offline and the plant has run at half of its nominal capacity.
