REDSTONE SOLAR THERMAL POWER PLANT T he Redstone Solar Thermal Power Plant (Redstone
Thermal Power Project features molten salt energy storage technology in a tower configuration with the capability to support South Africa’s demand for energy when it’s needed most – day and night. The 100 MW project with 12 hours of full-load energy storage will be able to reliably deliver a stable electricity supply to more than 200 000 South African homes during peak demand periods, even well after the sun has set. Fuelled completely by the sun, with no backup fuel required, the project also features dry cooling of the power generation cycle as an important element to minimise water use. With the lowest delivered electricity price of any CSP project in the country to date, the Redstone project will generate more than 480 000 megawatt-hours per year. This annual output is more than twice that of other technologies per MW of capacity, such as photovoltaics (PV) or direct steam solar thermal.
SCP) has been developed to meet the increasing electricity demands in the Republic of South Africa, which forms part of the South African Renewable Energy Independent Power Producer (REIPP) Procurement program. It is the first and largest CSP- financed molten salt central receiver project in South Africa. The project owner is ACWA Power, Eskom is the off-taker, and SEPCOIII Electric Power Construction Co Ltd is the EPC Contractor for this project. CHRYSO is the admixture supplier and Scribante Concrete is the concrete supplier for the project. Scribante Concrete's mobile batching plant was erected at the site. This project site is located on the remainder of the farm 469, The Hay District (Administration District), approximately 5 km South East of the Groundwater community and 30 km East of Postmasburg & falls within the jurisdiction of the Tsantsabane Local Municipality of the ZF Mcgawu District in the Northern Cape Province, South Africa. The project's scope includes engineering, procurement, construction, commissioning and maintenance of the 100 MWe Net Concentrated Solar Power Redstone Project. The Redstone Solar Thermal Plant construction is considered one of the largest innovations of 2022. Located in the Northern Cape Province of South Africa, the Redstone CSP project will be equipped with a 12-hour thermal storage system that will deliver clean and reliable electricity to nearly 200 000 households around the clock. Commencement of operations is scheduled for Q4 2023. In addition to efficiently delivering clean energy to the national grid, the Redstone project will offer tangible socioeconomic value through utilising local supply chains and creating job opportunities: the project will reach close to 44% local content on procurement during the construction period; create more than 2 000 construction jobs at peak, with about 400 from the local community; and create approximately 100 permanent direct jobs during the operating period. The first of its kind in Africa, the Redstone Solar
