Project Description

This summary covers an application made by Atlantica Yield PLC’s to cover its equity and shareholder loan investments in an existing Concentrated Solar Power plant against the risk of Breach of Contract (BoC) as part of the company’s overall risk management strategy.

KaXu Solar One (the Project) is a 100 MW CSP plant located in the Northern Cape Province in South Africa. The Project consists of a solar field with parabolic trough collectors and a heat transfer fluid (HTF) system, a molten salt Thermal Energy Storage (TES) system, a steam cycle and steam turbine generator, a cooling system and other auxiliary equipment. The stored thermal energy can be discharged anytime to keep the power plant running during times of low solar radiation and is used to extend power production after sunset, allowing the plant to extend electricity generation by approximately 3 hours.
