South Africa - Redstone 100MW Concentrated Solar Power (CSP) Project

The Redstone Concentrating Solar Power Plant (CSP) Project is designed to design, build, operate and maintain a 100 MW capacity concentrated solar power plant. It is expected to close the energy supply gap, reduce dependence on coal, limit carbon emissions, create local jobs, and develop a national solar energy industry. Redstone's capacity will be increased, with a thermal storage potential increased to 12 hours (1,200 MWh), a relatively economical option compared to battery storage used in photovoltaic solar power plants. The thermal storage system will allow the Redstone CSP (100 MW) to operate at full capacity for 12 hours in the absence of solar radiation (after sunset or on temporary cloudy days). The project will provide the country with access to clean energy and reduce peak-hour production costs, and will be carried out by experienced private sector developers and contractors, particularly ACWA and Solar Reserve.
