Seriti Green, the clean-energy unit of South African tycoon Mike Teke’s Seriti Resources, has reached financial close and started construction on the third phase of its Ummbila Emoyeni wind farm in Mpumalanga, signaling a major shift in electricity supply in the country’s coal-heavy region.
The project will deliver more than 900 megawatts of renewable energy across seven phases. So far, the company has installed 25 wind turbines near Bethal, Davel and Morgenzon, a milestone in South Africa’s Just Energy Transition (JET). Seriti Green is now leading efforts to replace coal-fired power with clean energy in one of the country’s most traditional mining regions.
Seriti Green advances Mpumalanga wind power
With turbines in place and thousands of people gaining training and employment, the transition to cleaner power is moving beyond theory into real action. In just two years, Seriti Green has financed three phases totaling 465 megawatts, with the first phase secured in 2024 and the second completed in August 2025.
“Wind power in Mpumalanga was once thought impossible. Today, it is a reality,” said Peter Venn, CEO of Seriti Green. “The Just Energy Transition must deliver, and we are doing our part.” The third phase, which includes five wind farms, a solar facility, and a battery storage site, reached financial close through long-term funding from Standard Bank, RMB, and Absa, enabling full-scale construction to begin.
Sim Tshabalala, CEO of Standard Bank, said the projects align with South Africa’s energy needs. The first 155-megawatt phase is nearly complete and expected to start producing electricity in early 2026. About one-third of the electricity will power Seriti’s mining operations, while the remainder will be traded through NOA Group and the Energy Exchange.
Teke’s Seriti Resources drives renewable growth
Seriti Resources, majority black-owned through Mike Teke’s Masimong Group, Thebe Investment Corporation, Zungu Investments, and Community Investment Holdings, remains active in South Africa’s coal sector. Under Teke, the company launched Seriti Green in 2021 and acquired a controlling stake in Windlab Africa’s wind and solar projects in 2022.
Seriti Green, which includes Windlab Development South Africa and Windlab East Africa, manages 23 projects totaling 2.65 gigawatts at various stages of development. Its portfolio includes operational wind farms along South Africa’s West Coast and the Amakhala Emoyeni wind farm in the Eastern Cape. Ownership is divided among Seriti Resources (54.19 percent), VennEnergy (14.99 percent), RMB (15.41 percent), and Standard Bank (15.41 percent).
The company is developing 1,300 megawatts of projects across the Western Cape, Eastern Cape, and Mpumalanga, alongside a 2,000-megawatt pipeline in Mpumalanga. Seriti Green has also expanded into East Africa with the 300-megawatt Miombo Hewani wind farm in Tanzania and the 120-megawatt Meru County Energy Park in Kenya.
