The Damlaagte Solar PV Farm near Parys in South Africa’s Free State province has reached full commercial operation, following construction that began after financial close in late 2023. The facility now supplies clean electricity to Sasol and Air Liquide under 20-year corporate PPAs, supporting the companies’ decarbonization goals

The 20-year power purchase agreements (PPAs) signed with Sasol and Air Liquide are integral to their collaborative effort in advancing sustainability and reducing carbon footprints. Hein Reyneke, Mainstream’s General Manager for Africa, expressed pride in the partnership, highlighting the efficiency and cost-effectiveness of the solution to meet decarbonization needs.

Mainstream’s role as a leading developer of renewable energy in South Africa positions it as a preferred partner for private PPAs. Reyneke emphasized the significance of such agreements in overcoming the country’s energy challenges, contributing swiftly and cost-effectively to energy security and addressing issues like load shedding.

Commencement and Operational Dates for Solar Farm Construction in Free State

The project is set to commence construction later this year with a target for full operational capacity by 2025. In addition to driving the clean energy transition, the project is set to make a positive impact on the local community. Job creation and socio-economic investments are earmarked as notable contributions, reinforcing Mainstream’s commitment to holistic development.

Hein Reyneke underlined the broader implications of this initiative, emphasizing its role in South Africa’s energy security and economic recovery. Mainstream’s robust project pipeline, comprising over 10GW of onshore wind and solar projects across multiple provinces, signifies a substantial contribution to the country’s renewable energy landscape.

Moreover, Mainstream Asset Management South Africa (MAMSA), a subsidiary of Mainstream, plays a crucial role by providing operations and maintenance services. This aspect ensures the long-term integrity and sustainability of the assets, further solidifying Mainstream’s comprehensive approach to renewable energy development and management.

The Solar PV Farm Now Fully Operational, Supplying Clean Power 

Since its inauguration in August 2025, Damlaagte has generated approximately 270 million kWh of renewable electricity in its first year of operation. The project, a collaboration between Mainstream Renewable Power, uBuzwe Energy, and Thembelihle Trust, represents South Africa’s first joint privately procured renewable project under corporate offtake agreements with Sasol and Air Liquide.

Construction progressed smoothly from late 2023, with the facility now fully operational. Furthermore, it is expected to maintain a 20-year lifespan supplying clean power wheeled via the national grid.

The success of Damlaagte echoes developments at other utility-scale solar projects in South Africa, such as the $240 million Orkney Solar Plant in North West province, which reached financial close in 2026 and is currently under construction. These projects collectively highlight the growth of private renewable energy procurement and corporate PPAs across the country’s energy sector.
