Mainstream has arranged ZAR 6.6 billion ($524 million) to invest in the two sites, the first of which could begin construction this month.
The 140MW Kangnas site near Springbok, Northern Cape and the 110MW Perdekraal East project, 80km northeast of Ceres, Eastern Cape, were awarded licences under the fourth round of South Africa’s Renewable Energy Independent Power Producer Procurement Programme (REIPPP) in June 2015.
However, signing of the power deals with state utility Eskom had been repeatedly delayed until April 2018, during a long-running legal process, which had all-but stopped any wind power development taking place in South Africa for almost two years.
A consortium of Concor and Conco has been appointed as construction contractor for the projects, while Siemens Gamesa Renewable Energy will supply and install the wind turbines, Mainstream said.
The projects are due online in 2020. They are Mainstream’s fouth and fifth South African projects, following completion of the Noupoort, Loeriesfontein, and Khobab projects in 2016-17, totalling 360MW.
