CSP plants generate electric power by using mirrors to concentrate (focus) the sun's energy and convert it into high-temperature heat. That heat is then channeled through a conventional generator.
Learn the basics about concentrating solar power and how this technology generates energy. What is concentrating solar-thermal power (CSP) technology and how does it work? CSP technologies use mirrors to reflect and concentrate sunlight onto a receiver. The energy from the concentrated sunlight heats a high temperature fluid in the receiver.
Concentrated solar power systems require a significant amount of land with direct sunlight or irradiance. Because of this, there are limited places to build these types of systems. CSP systems tend to be large, utility-scale projects capable of providing a lot of electricity as a power source to the grid.
Concentrated solar power (CSP) is a promising technology to generate electricity from solar energy. Thermal energy storage (TES) is a crucial element in CSP plants for storing surplus heat from the solar field and utilizing it when needed.
Concentrating solar-thermal power systems are generally used for utility-scale projects. These utility-scale CSP plants can be configured in different ways. Power tower systems arrange mirrors around a central tower that acts as the receiver.
The three main types of concentrating solar power systems are: linear concentrator, dish/engine, and power tower systems. Linear concentrator systems collect the sun's energy using long rectangular, curved (U-shaped) mirrors. The mirrors are tilted toward the sun, focusing sunlight on tubes (or receivers) that run the length of the mirrors.
