Anglo American Platinum Ltd together with Vuselela Energy and H1 Holdings has commissioned a cogeneration plant at its Waterval Smelting Complex in Rustenburg, South Africa.

It uses waste heat from the Anglo Converter Plant (ACP) convertor cooling circuit to evaporate an organic liquid and drive an expansion turbine. The plant has an installed capacity of 5 MWe of which 4.3 MW is available to the grid, reducing capacity bought from utility supplier Eskom.

The Eternity Power Thermal Harvesting project was commissioned in June 2015 and developed by Vuselela Energy in collaboration with Anglo American Platinum at a total project cost of R150million ($11 million). The Eternity Power project was made possible by a Department of Trade and Industry (DTI) grant worth R30million ($2.21 million) from its Infrastructure Development Support package.

Jacques Malan Director at Eternity Power and Vuselela Energy, said: ‘The set of technologies used at the Eternity Power clean energy plant had not previously been used in a smelter environment and a significant amount of novel work was done to design the integration of the technology into the smelter complex and to establish the technical feasibility of the process.’
