Mainstream is the biggest independent winner in South Africa’s announced tenders to-date securing eight projects with a total capacity of 848 MW. 

Mainstream entered the South African market in 2009 through a local joint venture partnership. Mainstream's strategy is to form partnerships to compete in the Government's REIPPP and this has enabled the company's success in the competitive auctions.

Mainstream develops, manages construction activites and delivers projects into commercial operation.  It provides operations and maintenance through its subsidiary, MAMSA.
