What is one primary use of solar concentrating thermoelectric power plants?

Solar concentrating thermoelectric power plants primarily focus on electricity generation. This type of power plant uses mirrors or lenses to concentrate sunlight onto a small area, typically a receiver, where the intense heat is converted into thermal energy. This thermal energy is then used to produce steam that drives turbines connected to generators, ultimately converting the thermal energy into electrical energy.

Unlike other options, which pertain to direct thermal applications, the design and function of solar concentrating thermoelectric power plants are specifically optimized for large-scale electricity output. While there are technologies that can use solar energy for water heating or cooling systems, these applications are distinct from the primary operation of thermoelectric power plants aimed at generating electricity for the grid.
