We are looking at building 50 wind turbines with 2 megawatts each before the end of this year across the country, said Fani Zulu, spokesman from Eskom.
Although he declined to give the cost of the project, Zulu said that it would cost more than the current coal-fired plants.
It is a little more expensive than generating electricity by coal, but by all means, it is a worthwhile cost, Zulu said.
Zulu also said that the country, which will host the 2010 World Cup, needs to construct new power stations to avert a repeat of the blackouts that crippled the nation in January 2008.
Eskom said in 2008, it was doubling its spending to ZAR343 billion ($36.3 billion, EUR26 billion) over the next five years to construct new power plants and expand transmission lines.
Eskom has struggled to meet increasing demand for electricity and in 2008, it has been forced to launch power rationing, which has hurt the economy and especially the critical mining industry.
