Abengoa CSP SA

active

The Project consists of the construction and operation of two greenfield concentrating solar power (“CSP”) projects near the towns of Upington and Pofadder, in South Africa’s Northern Cape Province, by Abengoa Solar, through its affiliates Abengoa Solar South Africa (Pty) Ltd (“ASSA”) and Son Revieren (Pty) Ltd, in partnership with the Industrial Development Corporation (IDC). Abengoa Solar’s parent company, Abengoa S.A. (“Abengoa”) is a leading developer of renewable energy projects. CSP is a general term used to describe a variety of technologies by which solar energy is concentrated onto a receiver with the subsequent concentration of heat used to power applications such as the generation of electricity by a steam-driven turbine. The 100 MW plant (“!KaXu Solar One”, or “Pofadder Solar Thermal Plant”) will utilize parabolic trough (“PT”) CSP technology. PT technology involves a field of pivoting concave mirrors tracking the sun, and concentrating the reflected sunlight onto a closed circuit network of piping that contains synthetic oil. The heated oil cycles through a generator creating steam to drive a 100 MW net capacity turbine. The electricity generated is transmitted through a high voltage substation for dispatch to the grid. The plant design includes a molten salt thermal energy storage (“TES”) system that allows for extended electricity generation of up to 2.5 hours for controlled dispatch during cloud cover or to meet evening electricity demand. The 50 MW plant (“!Khi Solar One”, or “Upington Solar Thermal Plant”) will utilize a central receiver, also known as solar power tower technology. The tower technology captures solar radiation in a field of dual axis mirrors that track the sun, and concentrate the reflected sunlight onto receivers (steam generators) located on top of a single 200m tower. Superheated steam is piped to a 50 MW net capacity turbine that generates electricity, which is transmitted through a high voltage substation and dispatched to the grid. The plant design includes a high pressure steam storage system, which like the molten salt TES of the !KaXu plant, allows for controlled dispatch during cloud cover or to meet evening electricity demand.Each of the CSP power plants will be owned by a special purpose project company (the “Company” and together the “Companies”).The actual footprint of the !KaXu and !Khi power plants are 300 ha each. Infrastructure components for both plants are similar and include: a solar field equipped with mirrors; a power island/tower housing a steam generator, steam turbine, power generator, transformer, auxiliary boilers and associated equipment (including thermal storage); an overhead power line feeding to an on-grid substation; a water abstraction point, supply pipeline and reservoirs to provide water for steam generation and mirror cleaning and storage of blow down water; and access roads and service buildings.
