A solar power tower, also known as ''central tower'' power plant or ''heliostat'' power plant, is a type of solar furnace using a tower to receive focused sunlight. It uses an array of flat, movable mirrors (called heliostats) to focus the sun''s rays
The paper examines design and operating data of current concentrated solar power (CSP) solar tower (ST) plants. The study includes CSP with or without boost by combustion of natural gas (NG), and with or without thermal energy

The National Institute of Solar Energy (NISE) says India could make 748 GW from solar energy. This makes it a giant in the solar power world. By mid-2023, India had made about 70.10 GW from clean energy stations.
A solar power tower, also known as 'central tower' power plant or ' heliostat ' power plant, is a type of solar furnace using a tower to receive focused sunlight. It uses an array of flat, movable mirrors (called heliostats) to focus the sun's rays upon a collector tower (the target).
All the issues commented above make solar power towers, among other concentrated solar power technologies, a promising technology with commercial possibilities in the mid term. Better performance and cheaper electricity compared with other options seems within reach.
A solar power tower consists of an array of dual-axis tracking reflectors (heliostats) that concentrate sunlight on a central receiver atop a tower; the receiver contains a heat-transfer fluid, which can consist of water-steam or molten salt. Optically a solar power tower is the same as a circular Fresnel reflector.
Due to this experience, sodium as a HTF was never used again in solar tower power plants. A solar thermal power station consists of a conventional block-unit power station and a solar component which replaces the combustion chamber of a conventional power station.
The development of solar tower power plants aims to use higher concentrating solar radiation compared to parabolic trough as the power plant process at higher temperature and therefore operates with better efficiency. Higher temperature is also an advantage for storage of thermal energy, as storage volume per unit of energy can be reduced.
In summary, the power tower concentrating solar power plant, at the heart of which lies the heliostat, is a very promising area of renewable energy. Benefits include high optical concentration ratios and operating temperatures, corresponding to high efficiency, and an ability to easily incorporate thermal energy storage.
