The three wind projects include the 140MW Khobab and 140MW Loeriesfontein 2 in the Namakwa municipality and the 80MW Noupoort in Umsobomvu.
A Mainstream-led consortium was selected by the Department of Energy in South Africa in October 2013 for the development of three wind farms under the third round of the country’s Renewable Energy Procurement Program.
Construction of the three wind facilities in South Africa’s Northern Cape province is scheduled to commence this month.
Mainstream onshore procurement construction and operations managing director Barry Lynch said: "Globally, Mainstream continues its aggressive wind and solar expansion programme; we have hundreds of megawatts in construction and operation in Ireland, Chile, Canada and of course South Africa.
"We are close to putting additional projects into construction in Chile in the coming months and recently received consent to build and operate two multi-billion pound offshore wind farms in the UK."
