Reports of a tender process being under way for six new nuclear power plants are wrong, says South Africa's Department of Energy.
"At no point has the Government committed to build six new nuclear reactors," it said.
The Government "hasn't selected any design, vendor nor suppliers of the nuclear power plants.
"No decision has been made on the actual number."
South Africa plans to diversify away from coal, which makes up more than 90 per cent of its generation capacity of about 40,000MW.
