South African Government warned that on Monday 31 August, Unit 2 of the Koeberg Nuclear Power Station will be shut down for maintenance which will take about three months to carry out.
Koeberg contributes around 1 800 MW to the grid and will lose half that capacity during the maintenance work.
This will increase the risk of load shedding over the next three months.
Construction of Koeberg began in 1976 and Unit 1 was synchronised to the grid on 4 April 1984, with Unit 2 following suit on 25 July 1985.
The Government also announced further delays at Medupi, with the coal power station now only expected to contribute to the national grid in 2019.
The power station was initially expected to cost R 80 billion but is now forecast to cost about R 154 billion.
Medupi was supposed to come online in 2015.
