Power utility Eskom on Tuesday highlighted the success of the upgrade of the second reactor (known as Unit 2) of its two-reactor Koeberg nuclear power plant, located north of Cape Town. On Monday (March 9), Unit 2 had accumulated 365 days of uninterrupted operation, with an average energy availability factor (EAF) of 99.4%. In practice, this meant that Unit 2 reliably delivered some 946 MW of electricity to the national grid. “This milestone follows major upgrades to Unit 2, which returned to the grid on 30 December 2024 and has operated continuously since 9 March 2025,” pointed out Eskom Group Executive for Generation Bheki Nxumalo. “It showcases the strength of South Africa’s nuclear skills base. The successful installation of the new steam generators highlights the skill and dedication of the Koeberg team, engineers, technicians, operators, and support staff, who have worked tirelessly to ensure the unit runs safely and efficiently.”
