Thermal energy storage provides a workable solution to this challenge. In a concentrating solar power (CSP) system, the sun's rays are reflected onto a receiver, which creates heat that is used to generate electricity that can be used immediately or stored for later use. [1][2] The 280 MW plant is designed to provide six hours of energy storage. It allows households and businesses to store excess energy generated during peak sunlight hours, reducing electric bills while contributing to renewable energy goals. It is an effective way of decoupling the energy demand and generation, while plays an important role on smoothing their fluctuations.
