It will supply 480GWh of clean electricity to South Africa’s power grid annually The 100MW Redstone Concentrated Solar Thermal Power (CSP) plant is the first tower CSP project in sub-Saharan Africa. Located in Postmasburg, Northern Cape Province, South Africa, it is one of the most massive renewable energy investment projects in the country and attained its first partial grid synchronisation in September 2024. The CSP plant adopts advanced tower-based molten salt storage technology, with 41,260 heliostats installed on-site. The mirrors precisely reflect sunlight onto the 248-metre-high solar tower’s heat receiver, heating the molten salt from around 290°C to ~565°C. Concentrated Solar Thermal Power (CSP) plant creates jobs, training opportunities The heated molten salt is stored in specially designed tanks, allowing the unit to run at full capacity for up to 12 hours, ensuring continuous power generation overnight. The project has generated over 600 jobs locally, with around 1,800 workers employed during the construction peak, contributing significantly to the local economy and social development. Additionally, more than 400 local engineers and technicians have received training, enhancing the overall skill of the local workforce through knowledge and expertise sharing. The project will supply 480GWh of clean electricity to South Africa’s power grid annually, meeting the electricity needs of about 200,000 households. It will significantly reduce reliance on traditional fossil fuels and lower local carbon emissions, making a vital contribution to the country’s just energy transition. ESI |
