Solar Power Towers (SPT), also denominated Central Receiver Systems (CRS), are set up by a heliostats field which reflects solar radiation into a central receiver located atop a tower. These heliostats track the Sun with two axis. They are also considered as point focus collectors.
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.
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.
The power tower plant is typically the largest of the CSP designs, consisting of a field of mirrors, heliostats, that track the sun throughout the day and year to maintain a constant focal point on the receiver, which consists of absorber panels of tubes near the top of the tower .
2.3. Thermo-economic data Regarding efficiency values and as a general overview, it can be highlighted that thermal efficiency (solar to mechanical) is estimated between 30% and 40% for solar power towers.
In 2018, worldwide and operational solar power tower gross installed capacity was 618.42 MW and, in the following years, it will finish achieving 995 MW . The overall capacity of under construction and development solar power towers reached around 5383 MWh e in 2019, with an average power capacity of 207 MWh e .

Solar power tower
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). Concentrating Solar Power (CSP) systems are seen as one viable solution for renewable, pollution-free energy.
