A Solar Breakthrough in South Africa
ACWA Power Leads Innovation with Redstone CSP Project
A consortium led by ACWA Power, has developed the Redstone CSP Independent Power Project located in Northern Cape Province, 600 km west of Johannesburg in the Republic of South Africa. The newly developed project will generate power by using Concentrated Solar Power “CSP” tower technology in South Africa. Redstone CSP Project has been developed by ACWA Power as lead developer together with Solar Reserve as co-developer.
The Redstone CSP project is a Greenfield Independent Power Project (IPP) developed as part of South Africa’s renewable IPP program. The project will be developed on a BOO (build, own, operate) with a total power generating capacity of 100 MW net power output. The project will be equipped with the largest thermal storage size ever adopted in South Africa and is among the most efficient solar plants in the world operating in this class of capacity and technology yielding a record high generation in excess of 480 GWh/year to support the power grid of South Africa.
