Koruson 2 Wind and Solar Project in South Africa has reached full commercial operation. It adds 520 MW of wind and solar power to the national grid. Envusa Energy, a joint venture between Anglo American and EDF power solutions, developed the cluster.
A similar shift towards cleaner energy is underway where the Mpumalanga Wind Farm project is advancing as part of South Africa’s broader renewable energy expansion.
The investment totals R15 billion to R16 billion and spans the Eastern Cape and Northern Cape. It combines three facilities: the 240 MW Mooi Plaats solar PV plant, the 140 MW Umsobomvu wind farm and the 140 MW Hartebeesthoek wind farm.
The project supplies renewable electricity to energy-intensive industries, including mines and processing facilities operated by Valterra Platinum, Kumba Iron Ore and De Beers.
Power from the three facilities enters South Africa’s national grid under long-term offtake agreements. Therefore, the project is expected to cut carbon dioxide emissions by about 2.2 million tonnes annually. It will also help industrial customers manage electricity costs and reduce reliance on coal-fired power.
Koruson 2 Wind and Solar Project in South Africa Reaches Full Commercial Operation
Koruson 2 is the first major generation portfolio delivered under Envusa Energy’s renewable energy programme.
The cluster reached commercial and financial close on 28 February 2024 after being awarded in October 2021. Its construction involved coordinating three generating facilities in two provinces and connecting them to shared high-voltage transmission infrastructure.
Mooi Plaats was the first facility to enter commercial operation in March 2026. The 140MW Umsobomvu wind farm followed in April 2026. At the cluster’s inauguration on 24 April 2026, the two facilities had brought 380MW of capacity into operation, while Hartebeesthoek was progressing through its final construction and commissioning stages.
By August 2026, all three projects had officially entered commercial operation. By 5 August, 130 MW of Hartebeesthoek’s 140 MW capacity was commercially operational, while the remaining 10 MW was scheduled to come online in September. Envusa’s current project information now lists all three generators as operational.
The completion marks an important milestone for private-sector electricity generation in South Africa. It demonstrates how wind and solar projects can be combined into a single power supply portfolio for large commercial and industrial customers.
Three Renewable Energy Facilities Form The Koruson 2 Project Cluster in South Africa
The Koruson 2 portfolio consists of three utility-scale renewable energy facilities.
240 MW Mooi Plaats Solar PV Farm
Located in the Northern Cape, the solar facility uses photovoltaic panels to convert sunlight into electricity. It entered commercial operation in March 2026 and provides the largest share of the cluster’s installed capacity.
140 MW Umsobomvu Wind Farm
Located in the Eastern Cape, the wind farm uses wind turbines to generate electricity. It entered commercial operation in April 2026.
140 MW Hartebeesthoek Wind Farm
The second wind facility completed the cluster’s generation portfolio during 2026. Its final capacity is progressing through commercial commissioning by the end of the third quarter.
Together, the projects provide 520MW of installed renewable generation capacity. The cluster comprises approximately 50 wind turbines, 420,000 solar panels and 943 string inverters. The inverters convert the direct current generated by the solar panels into alternating current suitable for transmission through the electricity network.
The combination of wind and solar technologies allows the portfolio to draw on two renewable resources. Solar generation is concentrated during daylight hours, while wind output varies according to weather conditions. Aggregating electricity from the three facilities enables Envusa Energy to manage supply across its customer portfolio.
Koruson Transmission Substation Supports Grid Connection
The three generation facilities connect to the Koruson 400kV Main Transmission Substation, developed as part of EDF power solutions’ wider Koruson 1 project cluster. The substation provides the high-voltage connection required to transmit electricity from the renewable facilities into the national grid. It is designed to support connections for up to 1.5GW of renewable energy generation.
The transmission infrastructure is central to the project’s operating model. Instead of relying on a direct physical connection between each generating facility and every customer, electricity is injected into the national grid and allocated through an electricity wheeling arrangement.
Envusa Energy aggregates generation from multiple assets and supplies power to industrial customers under contractual agreements. This approach allows electricity produced in the Northern and Eastern Cape to support mining and processing operations in other parts of South Africa, subject to grid and commercial arrangements.
The development therefore includes more than the wind turbines and solar panels. Its delivery required coordination between renewable generation facilities, grid connection infrastructure, transmission access, power trading and long-term offtake agreements.
Koruson 2 Wind and Solar Project in South Africa: Investment, Financing And Delivery
Koruson 2 wind and solar power projects represents an investment of approximately R15 billion to R16 billion.
Envusa Energy was established in 2022 as a joint venture between Anglo American and EDF power solutions.
Pele Green Energy holds a 20% equity stake in the three Koruson 2 project companies.
Community trust also provides a mechanism for local participation in the long-term benefits of the development.
Financial partners including Absa, Nedbank and Rand Merchant Bank supported the funding platform.
The project’s commercial and financial close in February 2024 provided the basis for advancing construction across the three sites. Delivery then progressed through separate commissioning milestones, culminating in the full cluster’s commercial operation during 2026.
Renewable Power Supports Mining Decarbonisation
Koruson 2 wind and solar power project South Africa supplies renewable electricity to three major industrial customers.
Under the reported offtake arrangements, Valterra Platinum has contracted 461MW, Kumba Iron Ore 11MW and De Beers 48MW.
These contracted capacities total 520MW, matching the cluster’s installed generation capacity, although actual electricity production varies with wind and solar conditions.
The project is expected to avoid approximately 2.2 million tonnes of carbon dioxide emissions annually once operating at full capacity. The reduction comes from displacing electricity that would otherwise be supplied from more carbon-intensive sources.
For mining companies, renewable electricity can reduce operational emissions while supporting long-term energy procurement planning.
The project also generated economic benefits during construction. More than 2,000 direct and indirect jobs were created. About 80 small, medium-sized and micro-enterprises from surrounding communities participated in project-related work. More than R70 million was also directed towards local economic activity and development initiatives.
Envusa Energy’s Expansion Plans
Koruson 2 wind and solar power project in South Africa also forms part of Envusa Energy’s wider ambition to develop between 3GW and 5GW of renewable energy capacity across Southern Africa by 2030.
Furthermore, the company is advancing another tranche of wind projects with a combined capacity of 340MW, with financial close targeted for the first quarter of 2027 and commercial operation planned for 2029.
The next phase is expected to build on the model demonstrated by Koruson 2 wind and solar power project which combines private investment, renewable generation, grid access and long-term industrial power agreements.
Koruson 2’s full operation also establishes a major reference project for South Africa’s private renewable energy market. Its combination of solar, wind and transmission infrastructure demonstrates how multiple generation assets can supply industrial customers through the national grid while contributing to emissions reduction and electricity supply diversification
