Integration of TES in CSP plants is important for improving environmental issues as well as alleviating the global energy crisis. This chapter provides a comprehensive discussion on the integration of Thermal Energy Storage systems (TES) in Concentrating Solar Power plants (CSP) plants worldwide. Different TES technologies and their implementation in commercial-level CSP plants are discussed. It was observed from the discussion that CSP technology is already developed for commercialization. A good number of well-established CSP plants are producing electricity worldwide, led by Spain and the United States. In addition, a good number of commercial CSP plants are under construction or in the project state hinting towards a development of the renewable energy sector in the future.

The integration of TES into CSP plants is one of the major design changes that results in significant benefits including uninterrupted electricity production even during a day without the sun radiation or nighttime. Such systems will make the CSP plant more sustainable as well as more economically competitive and dispatchable. Even though a good number of CSP plants have been using TES, fast progress is needed in the TES technologies. As observed from the current state of the art, a large number of CSP plants implement sensible thermal energy storage systems. This is due to the reliability, low cost and large data owing to sensible energy storage. However, based on the disadvantages like low energy storage density, new ways like latent and thermochemical energy storage systems may be considered for future CSP plants. Latent and thermochemical energy storage systems have larger energy storage density which might lead to a bright future for CSPTES technology. However, more research efforts are needed to overcome the disadvantages of latent and thermochemical energy storage systems.
