Leading independent developer

Mainstream is the second biggest winner in South Africa’s announced tenders to-date securing eight projects with a total capacity of 842 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. 

Mainstream asset management SA

Headed up by Titania Stefanus-Zincke, Mainstream Asset Management South Africa (MAMSA), operates and maintains utility scale wind and solar projects to ensure long term asset integrity.  The company operates over 600 MW of wind assets on behalf of its joint venture company, Lekela Power. 

The MAMSA objective is to maximize availability, production and revenue at an optimal cost level.  Key to achieving this is the implementation of safety systems to ensure zero Lost Time Incidents and to operate in a respectful manner that accounts for the social and environmental impact created by the business.

MAMSA ensures that all projects are managed in compliance with the applicable laws, regulations, permits and project agreements. Lender and Equity Reporting remains a core output of the MAMSA service offering. Working with communities to transition to economic independence through the implementation of Socio-economic and Economic Development projects remains one of the strengths of the MAMSA team.
