- 148 MW facility to deliver about 300 GWh of electricity annually to Richards Bay Minerals under a 20 year corporate power purchase wheeling agreement.
- Development marks first women backed large scale photovoltaic project for an industrial client in South Africa and created about 800 jobs during construction.
Independent power producer Voltalia has announced the full commissioning of the 148 MW Bolobedu solar power plant in Limpopo, marking a major milestone for corporate renewable energy procurement in South Africa. The project is the first large scale photovoltaic installation in the country developed specifically for a private industrial offtaker.
The plant is expected to generate approximately 300 GWh of clean electricity each year. All output is supplied to Richards Bay Minerals, a subsidiary of Rio Tinto, under a 20 year corporate power purchase agreement. Electricity is transmitted to the mining operations in KwaZulu Natal through a wheeling arrangement using the national grid operated by Eskom.
The project is expected to avoid more than 237,000 tonnes of carbon dioxide emissions annually, reinforcing the growing role of renewable energy in decarbonising energy intensive industries in Africa.

Construction of the facility generated employment for approximately 800 local residents and incorporated structured training programmes aimed at building long term technical capacity in solar installation, engineering support, and safety operations. The project is also notable as the first large scale renewable energy development in South Africa backed exclusively by women investors in partnership ith Black Economic Empowerment stakeholders, highlighting an evolving investment landscape in the regional energy sector.
The commissioning aligns with a broader strategic partnership between International Finance Corporation and Voltalia, signed in October 2025, focused on accelerating decarbonisation in the African mining sector through power to mine initiatives.
The project also reflects the expanding role of energy wheeling in South Africa’s electricity market. Wheeling enables privately generated electricity to be transported across the grid from independent power producers to remote consumers without the need for direct dedicated transmission lines. In this model, electricity is injected into the grid at the point of generation and an equivalent amount is accounted for at the point of consumption, with financial settlement managed through utility billing systems and use of system charges.
South Africa is also advancing toward virtual wheeling frameworks that aggregate consumption across multiple sites and simplify corporate procurement structures. Under this model, smart meter data is consolidated and renewable energy certificates are issued to support verified emissions reductions, an increasingly important mechanism for export oriented companies seeking compliance with international carbon border adjustment requirements.
