The Damlaagte PV Facility (Damlaagte) formally began commercial operation on 23 August 2025, marking the start of a 20-year operational period for this 97.5-megawatt (MW) site.
The Damlaagte solar PV facility located near Parys in the Free State is now in commercial operation.
Located near Parys in the Free State, Damlaagte connects to the Eskom grid and will provide about 270 million kilowatt hours (kWh) of clean electricity in its first year of operation. The facility is owned by Mainstream Renewable Power, uBuzwe Energy (Pty) Ltd, and the Thembelihle Trust. The plant, built and operated by Mainstream Renewable Power (Mainstream), is the first renewable energy project to supply power under a landmark joint procurement programme initiated by its strategic partners, Air Liquide and Sasol.
The renewable energy from Damlaagte will be supplied to the Secunda site where Air Liquide owns and operates the world's largest oxygen production facility, having acquired it from Sasol in 2020. The project forms part of the joint Air Liquide and Sasol initiative to procure a total of nearly 700 MW of renewable power for these operations. The programme is a key enabler for both companies to achieve their decarbonisation goals.
“The Damlaagte PV Facility coming online marks another great accomplishment for us in our journey towards lower carbon intensity in our operations,” said Simon Baloyi, President and Chief Executive Officer of Sasol. “This year, we have achieved several milestones in our renewable energy plan, including securing an additional 160 MW, bringing our total renewable energy secured in South Africa to more than 900 MW. We are well on track to meet our 2030 renewable energy target of up to 2 GW.”
Nicolas Poirot, CEO, Africa, Middle East & India (AMEI) for Air Liquide, said: “Damlaagte reaching commercial operation is a major milestone for the decarbonisation of our operations in Secunda, the world's largest oxygen production site. It is a significant step towards our goal of reducing CO₂ emissions from the Secunda operations by 30% to 40% by 2031, and a demonstration of our global commitment to decarbonisation.”
Energy policy and supply are not only about technology but also have a strong influence on economic growth and socio-economic development. Construction of Damlaagte started in November 2023 and close to 2 000 people were employed on the project, coming from nearby communities including Tumahole, Schonkenville, and Vredefort. Damlaagte and its partners, Power China Maanda, LeadEPC, and Tractionel Holdings, used the services of local businesses where applicable and established a skills development programme through which more than 100 people were trained.
“uBuzwe, a member of the Kholosani Group of Companies, is an infrastructure investment company with a portfolio that includes 17 renewable energy assets. uBuzwe has experience in the solar, solar thermal and wind power generation sectors and currently generates over a 1 000 GWh per year of clean energy. We drive solutions for the development and improvement of critical infrastructure projects across South Africa,” says Indiran Pillay, uBuzwe Director.
Hein Reyneke, Mainstream’s General Manager for Africa, says, “We are proud to partner with Sasol and Air Liquide, delivering an efficient and cost-effective solution to their decarbonisation needs. As one of the most successful developers of renewable energy in South Africa, Mainstream is well positioned to participate as a partner in private PPAs. Power purchase agreements are key to unlocking the country’s energy constraints, as they can make a significant contribution to increasing energy security and overcoming load shedding challenges quickly and cost-effectively. Mainstream is at the forefront of the energy transition.”
