South African CSP Project: Khi Solar One


Khi Solar One (50 MW) will be Abengoa´s third commercial solar tower and its first outside of Spain. The tower plant will be located on a 1482 acres site close to Upington, in the Northern Cape Province.


Project details

  • The plant, with 2 hours of thermal storage, will use a technologically advanced dry cooling system, which dramatically reduces water consumption by two-thirds.

  • The plant will also contain important technological advances in efficiency, using higher temperatures during the generation process, and having more than double the capacity of Abengoa’s previous towers. These advances come as a result of the latest generation of solar tower technology using superheated steam, which was developed by Abengoa in its R&D centers in Spain.

Environmental – social – economic benefits

  • Khi Solar One will prevent approximately 183,000 tons of CO2 emissions per year, and will supply clean energy to approximately 45,000 households.

  • The plant will create an average of 600 jobs during construction, and approximately 35 permanent, full-time jobs during plant operation.

  • It will contribute to South Africa´s goals of introducing up to 17,800 MW of renewable energy by 2030, and reducing its dependence on oil and natural gas.
