South Africa
Key Project: 100MW Redstone Concentrated Solar Thermal Power (CSP) Plant
Project Location: Northern Cape province, South Africa
The 100MW Redstone Concentrated Solar Thermal Power (CSP) Plant, which is part of the South African Renewable Energy Independent Power Producer (REIPP) Procurement Program, is the first project financed CSP with molten salt central receiver project in the world and one of the largest investments in South Africa under the REIPP.
Redstone 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 without the sunlight.
The heliostats of the project follow the sun and reflect the sunlight onto a 250m-tall central receiver tower, which uses molten salt as heat transfer fluid and storage medium.
The thermal to electric power conversion unit will comprise 115MW high-temperature subcritical steam turbine-generator units.
Auxiliary infrastructure includes two molten salt storage tanks, air-cooled condensers, water purification system, sewage treatment facility, an evaporation pond, emergency.

Key projects:
1. Kariba South Extension Project
Situated on the south bank of Kariba Reservoir, the Kariba South Power Station played a vital role in providing electricity for Zimbabweans. As the Zimbabwean economy grows, the power station needed to expand its capacity. The project started on 10 November 2014 and was successfully completed four years later on 10 March 2018.
The newly installed capacity of the KSEP is 2×150MW. By the end of December 2021, Unit 7 & 8 had each generated 2,532,287.083 MWh and 2,514,742.958 MWh. Running at their full capacity, the newly installed power units are able to provide 1.5 times as much electricity as is needed by the city of Harare everyday. The KSEP is estimated to have generated economic benefits worth 497.6 million USD.
2. Hwange Power Station Expansion Project
The Hwange Power Station Expansion implemented by Sinohydro is one of the largest projects under the Belt and Road Initiative and a Sinohydro flagship project under the finance-build-operate model.
It entails the construction of two additional units, i.e. unit 7 and 8, each with a capacity of 335MW, and power transmission and ancillary facilities. Upon completion, they will meet 50% of Zimbabwe's national electricity demand, greatly alleviating the country's power shortages.
