The potential to produce electricity from wind turbines in South Africa is more widely spread than initially thought, a study by the Council for Scientific and Industrial Research (CSIR) has determined.
CSIR energy centre head, Dr Tobias Bischof-Niemz, says the study outputs could serve as input into South African energy-planning processes such as the Integrated Energy Plan, the Integrated Resource Plan for electricity, strategic grid planning, the Transmission Development Plan and wind and solar PV strategic environmental assessments.
“The magnitude and cost competiveness of wind power in South Africa is on par with that of solar PV. In addition, wind and solar PV are complementary, with wind supply peaking in the evening and solar PV peaking at midday,” said CSIR energy centre group leader, Crescent Mushwana.
The total technical wind power potential in South Africa, if wind farms were to be installed across the country, was 6 700GW. To generate 250TWh/y, which was South Africa’s electricity demand, 0,6% of the available South African land mass would have to be dedicated for wind farms with an installed capacity of about 75GW. The study showed that more than 80% of South Africa’s land mass had enough wind resources for economic wind farms with very high yearly load factors greater than 30%.
