MPUMALANGA, South Africa — South Africa powers up the Ummbila Emoyeni Wind Farm, launching one of the country’s largest new renewable energy projects into commercial operation and signaling a major shift in its historic coal heartland. Located in the Mpumalanga province, the facility represents a critical step in expanding national electricity generation and cutting carbon emissions without compromising local energy security or community livelihoods.
For over a century, coal mines in Mpumalanga have powered the national economy. Today, giant wind turbines are spinning into action in that same region, marking a new era in the country’s energy journey. South African President Cyril Ramaphosa visited the site to officially celebrate the first phase entering commercial operation. During his address, Ramaphosa congratulated Seriti Green, describing it as a “proudly South African company.” He noted that despite being a young enterprise of less than ten years, the developer has built a proven track record in the nation’s coal industry and remains foundational to South Africa’s evolving energy production.
The newly activated 155-megawatt first phase is expected to generate approximately 480,000 megawatt-hours of electricity annually, providing enough renewable power for roughly 500,000 homes. The wind farm will churn clean electricity onto a grid historically fed by legacy coal-fired power stations. Over its operational lifespan, this initial phase is projected to produce 5.8 million megawatt-hours of clean energy, helping the nation avoid around 6.5 million tons of carbon emissions.
To bring advanced international green technology into one of the nation’s most coal-dependent regions, Seriti Green partnered with Chinese wind turbine manufacturer Goldwind, which supplied 25 turbines for the first phase. Chinese Ambassador to South Africa Wu Peng highlighted the deep bilateral ties driving the initiative, noting that it is proven in practice that Chinese enterprises are “not merely visitors from afar, but partners deeply rooted in South Africa” who are actively contributing to the nation’s development. Goldwind Vice Chairman Cao Zhigang also expressed pride in collaborating with local partners to advance sustainable growth and clean energy infrastructure.
Beyond environmental benefits, the project addresses vital economic transitions by creating more than 2,000 local jobs across project development, construction, operations, and the local supply chain. For communities historically reliant on coal mining, the central question remains whether renewable projects can deliver sufficient long-term employment to offset economic risks as the national energy mix evolves. Addressing these concerns, Seriti Green CEO Mike Teke emphasized the importance of lasting community impact. Echoing the president’s vision, Teke stressed the need to ensure that economic activity and opportunities endure well beyond the construction phase and into long-term operations, even if future projects move to other regions.
While coal remains central to South Africa’s electricity system and Mpumalanga’s economy, Seriti Green is actively building toward 900 megawatts of total renewable capacity. Ultimately, the Ummbila Emoyeni Wind Farm will serve as a crucial test case, demonstrating whether private investment and international cooperation can successfully transform the country’s coal heartland without leaving its communities behind.
