Almost 7,000MW of private energy generation had been registered by the National Energy Regulator of SA (Nersa) by the end of March 2024. About a third of this is wind power, mostly for wind farms.

The largest wind projects in SA are Hendrina South in Mpumalanga and Mulilo De Aar 2 South in the Northern Cape, each registered to generate 200MW. These facilities were two of seven wind farms registered in March 2023. Their combined capacity of 1,058MW was half the total power registered with Nersa between 2018 and 2024.

The Northern Cape has the highest number of registered private wind projects at 703MW, followed by the Western Cape (547MW) and the Eastern Cape (392MW). Two wind farms on the border of the Northern and Eastern Cape have a combined capacity of 290MW.

Farms and a fishing company registered the remaining wind power, with projects of 1MW or less.
