“The Ummbila Emoyeni wind farm in Mpumalanga has officially entered commercial operation, delivering 155 MW of clean energy through Eskom’s transmission network. Once fully developed, the 900 MW hybrid cluster—combining wind, solar, and battery storage—will be the largest of its kind in South Africa, symbolizing the country’s shift toward a diversified and sustainable energy mix.”
South Africa’s energy landscape is undergoing a profound transformation. On 9 August 2026, President Cyril Ramaphosa announced the commercial launch of the Ummbila Emoyeni wind farm, a flagship renewable energy project located in Mpumalanga. This development represents not only a technical achievement but also a symbolic turning point in the nation’s journey toward a cleaner, more resilient energy future.
Background: Mpumalanga’s Coal Legacy
For over a century, Mpumalanga has been the heart of South Africa’s coal industry. Its coalfields powered industrialization, fueling mines, factories, hospitals, and homes. Yet, this reliance on coal has also left the region with environmental challenges, including air pollution and carbon emissions. The decision to build South Africa’s largest hybrid renewable energy facility in this very region underscores the government’s commitment to balancing heritage with innovation.
Project Details
- Developer: Seriti Green, a subsidiary of Seriti Resources, one of South Africa’s largest coal producers.
- Current Output: 155 MW from 25 wind turbines.
- Future Capacity: 900 MW hybrid cluster (wind, solar, battery storage).
- Transmission: Energy wheeled through Eskom’s national grid to supply Seriti’s mining operations.
- Significance: Largest hybrid renewable energy facility in South Africa upon completion.
Strategic Importance
The Ummbila Emoyeni project aligns with the 2025 Integrated Resource Plan (IRP), which aims to diversify South Africa’s energy portfolio by:
- Increasing reliance on wind and solar.
- Reducing the share of coal.
- Supporting generation with gas, battery storage, and nuclear power.
This diversification is critical for ensuring energy security, reducing carbon emissions, and meeting international climate commitments.
Growth of Renewables in South Africa
- In 2016, renewables supplied just 2% of electricity.
- By 2021, this rose to 6%.
- By 2024, renewables accounted for 9% of generation.
- Current installed renewable capacity: 16 GW.
- Projects in grid connection pipeline: 32 GW, expected by 2030.
Economic Impact
The project is expected to:
- Create local jobs during construction and operation.
- Stimulate investment in green energy infrastructure.
- Support inclusive growth by involving domestic firms rather than relying solely on foreign investment.
- Attract over R50 billion in green energy commitments announced at the South Africa Investment Conference.
Environmental Benefits
- Reduction in carbon emissions by replacing coal-fired generation.
- Improved air quality in Mpumalanga.
- Contribution to South Africa’s climate targets under the Paris Agreement.
Challenges Ahead
Despite progress, coal remains dominant in South Africa’s energy mix. Transitioning to renewables requires:
- Expanding grid infrastructure to handle intermittent supply.
- Ensuring energy affordability for households.
- Managing the social impact on coal-dependent communities.
Political and Social Dimensions
President Ramaphosa emphasized that the just energy transition must balance environmental goals with social justice. Coal miners and power station workers in Mpumalanga are central to this narrative. Retraining programs, community development initiatives, and inclusive policies will be essential to ensure that no one is left behind.
Future Outlook
The Ummbila Emoyeni project is only the beginning. With 32 GW of renewable projects in the pipeline, South Africa is poised to become a continental leader in clean energy. The hybrid model—integrating wind, solar, and battery storage—offers a blueprint for future projects across Africa.
