US-based SolarReserve and Saudi Arabia’s Acwa Power are jointly undertaking the 100 MW Redstone solar thermal project. SolarReserve’s vice-president Terence Govender said at a media briefing this week that construction will begin by September.
The project is planned to feature 12 hours of full-load thermal storage capacity and is expected to power around 200,000 South African households during peak demand times.
SolarReserve said the plant will feature dry cooling in order to minimize water use.
The Redstone plant will be located in the town of Postmasburg in the Northern Cape province and will be built next to two existing solar photovoltaic (PV) plants, the 96 MW Lesesdi plant and the 75 MW Jasper plant. In combination, SolarReserve said the plants represent the world’s first combined PV and CSP solar park.
