Abstract
The increase of solar energy production has become a solution to meet the demand of electricity and reduce the greenhouse effect worldwide. This paper aims to determine the performance and viability of direct normal irradiation of three solar tower power plants in Algeria, to be installed in the highlands and the Sahara (Béchar, El Oued, and Djelfa regions). The performance of the plants was obtained through a system advisor model simulator. It used real data gathered from appropriate meteorological files. A relationship between the solar multiple (SM), power generation, and thermal energy storage (TES) hours was observed. The results showed that the optimal heliostat field corresponds to 1.8 SM and 2 TES hours in Béchar, 1.2 SM and 2 TES hours for El Oued, and 1.5 SM and 4 TES hours for Djelfa. This study shows that there is an interesting relationship between the solar multiple, power generation, and storage capacity.
Highlights
Algeria highlighted its solar potential where as of the most important heritages in theWorld, because more than 2 million km2 receive an annual insulation of about 2.5 kWh/m2 [1,2].The renewable energy program involves the installation of renewable power of the order of 22 GW by the year 2030 for the national market [3].The world market for solar thermodynamics (CSP) is estimated at 14 GW in 2020 and 72 GW on the horizon of 2035 in very strong growth compared to the capacity installed in 2012 which amounts to2.8 GW [4]
Each plant is equipped with a molten salt storage mode, the receiver is of external type and the implantation of the field of heliostats that has been defined for an annual production of 20 MW

Summary
Algeria highlighted its solar potential where as of the most important heritages in theWorld, because more than 2 million km receive an annual insulation of about 2.5 kWh/m2 [1,2].The renewable energy program involves the installation of renewable power of the order of 22 GW by the year 2030 for the national market (i.e., more than 37% of national electricity production with maintaining the export option as a strategic objective) [3].The world market for solar thermodynamics (CSP) is estimated at 14 GW in 2020 and 72 GW on the horizon of 2035 in very strong growth compared to the capacity installed in 2012 which amounts to2.8 GW [4]. Algeria highlighted its solar potential where as of the most important heritages in the. The renewable energy program involves the installation of renewable power of the order of 22 GW by the year 2030 for the national market (i.e., more than 37% of national electricity production with maintaining the export option as a strategic objective) [3]. This strategic choice is motivated by the potential of solar energy from the “Sahara and. This energy constitutes the major axis of the program which is devoted to solar thermal energy [5,6]. The geographic location of Algeria has several advantages to using solar energy. The climate is transitional between maritime (north) and semi-arid to arid (middle and south)
