A brief overview of the Ummbila Emoyeni wind farm, including its capacity and purpose
The Ummbila Emoyeni 900MW hybrid renewable energy facility will be the largest renewable hybrid energy facility in South Africa. Based in the Highveld, the project is set to redefine the Mpumalanga province’s journey towards a just energy transition, located between Bethal and Morgenzon in Mpumalanga. The entire project has been designated as a Strategic Integrated Project by the Department of Public Works and Infrastructure, and has already received its Environmental Authorisation from the Department of Forestry, Fisheries and the Environment, a critical requirement to start construction.
Ummbila Emoyeni, the first phase of this flagship project of 155MW, will supply Seriti’s coal mining operations with 75% of its power requirements of its power requirements via a wheeling agreement with Eskom, expected to commence commercial operation in 2025. The remainder of the 900MW project is expected to be fully commissioned by 2027, by which time it will provide electricity for the equivalent of ~500,000 South African households. In addition, Seriti Green is in the early development phase of a 1.3 GW project called Phefumula Emoyeni, which is adjacent to Ummbila Emoyeni in the Mpumalanga province.

Essential facts or statistics related to energy production and impact
Energy Heartland
As the hub of South Africa’s energy generation, primarily from coal, Mpumalanga has a developed infrastructure that can support additional forms of energy generation. Transitioning some of the energy production to renewable sources can help diversify and make the energy grid more sustainable.
Excellent Wind Resource
Locations for wind farms are carefully chosen
based on wind resource assessments. Mpumalanga’s topography and climate conditions will provide a consistent and strong wind flow, crucial for the efficient operation of wind turbines.
Coexistence with Coal Operations
A wind farm in this region can operate alongside existing coal power plants, offering a complementary energy source. This can be particularly advantageous during periods when wind energy production is high, allowing for reduced reliance on coal and consequently, a decrease in greenhouse gas emissions. This coexistence is pivotal for a gradual transition to renewables, ensuring energy security and stability during the shift.
Access to Existing Grid Infrastructure
The presence of an established energy infrastructure means that connecting a new wind farm to the grid
is more cost-effective and less complex. This access facilitates the immediate distribution of generated wind energy to consumers.
