The correct integration of a TCES to an SPT increases the system's competitiveness and decreases the cost of electricity compared to the current technology of storage.

The mean parameters to the simulation are mass flow and the temperature of the power block.

This study considers the SPT plant integrated into a TCES system.
The methodology is divided into three parts:
1 Selection of the type of TCES, power block, and input parameters.
2 Simulation of the system in TRNSYS program which is a program dedicated to solving this type of problems
3 The resultant configuration to be compared with the current technology. Some other programs are going to be used to perform calculations.

· To find new settings that integrate TCES to enhance the efficiency of the system.

· To generate a new methodology to simulate this system, which consists of a solar tower with a Brayton cycle in the power block integrated a TCES.

· A projection and comparison of the final configuration with the commercial systems in function of cost and efficiency

-The irradiance of the sun can be used as a renewable source of energy, and it is available around the world.

Concentrating solar power (CSP) technologies are systems that can transform solar energy into electricity. It consists of a heliostat field, the receiver, the power block, and thermal storage.
-One of the main problems of the SPT lies in the thermal energy storage (TES), which helps us to mitigate the intermittency and variability of the solar resource as a function of time, climate, and geographical location (Liu et al., 2018).

-There are four principal CSP technologies: parabolic through, linear Fresnel, parabolic dish, and solar power tower. This last one is the most remarkable for the developers of new energy projects due to its greater concentration capacity (Crespo, 2021).
