The South Africa Redstone EPC project has successfully achieved stable full-load operation at 100MW net output for the first time, with all system parameters meeting excellent standards. This milestone marks a significant breakthrough in the project’s construction progress.
As the first tower-type molten salt CSP plant in sub-Saharan Africa and the largest investment project in South Africa’s Northern Cape Province, the project employs advanced tower molten salt energy storage technology. It features 41,260 heliostats installed on-site. Upon completion, the plant will supply 480 GWh of clean electricity annually to the South African grid, meeting the power needs of approximately 200,000 households. This will significantly reduce reliance on traditional fossil fuels, lower local carbon emissions, and hold strategic importance for South Africa’s energy transition.
Located in the Northern Cape Province, the Redstone 100MW Tower CSP Project is South Africa’s largest tower-type CSP facility. Owned by ACWA Power, the project is EPC-contracted by SEPCOIII, a member of the CSPPLAZA platform. Utilizing tower CSP technology, the plant incorporates small-mirror heliostats with a total reflective area exceeding 1 million square meters. Its dual-tank (cold and hot) thermal storage system provides 12 hours of energy storage, enabling power supply during peak evening demand.
On September 14, 2024, the Redstone 100MW CSP plant, contracted by SEPCOIII, was successfully connected to the grid.
