###### Abstract
[PERSON] [34] analyzed the effect of the heat transfer fluid on four condenser models of an STPP plant. The results of that study suggest that the wet-cooled condenser shows better performance compared to the air-cooled condenser. [PERSON] et al. [35] combined the Wind-Pumped Hydro Storage Plant and the CSP power plants to assess their effectiveness on the Island of Rhodes. The results from their study suggest that renewable energy source penetration of about 80% can be achieved annually using the combination of both plants. An LCOE of 0.20 EUR/kWh was obtained as the best investment selling price for the electricity produced. Similarly, [PERSON] et al. [36] combined the PTC and the tower plants for an increased day to day performance. They found a steadier day-to-day performance for the system of the 29 MWe and 25 MWe towers of the north-south oriented PTC compared to the single-system power plants. [PERSON] et al. [37] evaluated India's solar thermal potential. They developed a comprehensive framework which took into consideration factors such as the direct normal irradiance, the availability of wastelands, suitability of wasteland for the generation of wind power, wastlands that are the habitat of endangered species or prone to earthquakes, and/or tribal population. [PERSON] et al. [38] assessed the cost effectiveness of the PTC technology in India. Their study indicated that a plant with a TES hour of around 7 h could reduce the cost of electricity from 0.15 USD/kWh to 0.14 USD/kWh. Using the System Advisor Model, ref. [39] evaluated the performance of two different solar thermal power plants, i.e., the linear Fresnel reflector and the PTC, under Indian weather conditions. They found that the levelized unit cost of electricity is minimal for the solar multiple (SM), ranging between 1.4 and 1.6 for a DNI of 950 W/m\({}^{2}\) for the PTC power plant, while the SM for that of the LFR is 1.8-2.0. The literature provides a considerable number of studies that have been conducted globally on CSP technologies. However, from the literature survey, studies based on CSP technologies in the Indian context under different weather conditions across the country are limited. This is important since India is vast with different weather conditions, and hence a study at a particular location cannot be used to predict the performance of such systems across the country. Therefore, in this present study, we examined the techno-economic feasibility of a CSP based on STPP for six different locations in India in order to fill this current research gap, which is useful for research directions and policy interventions [13; 15]. According to [PERSON] et al. [27], a dry-cooled CSP plant is modelled at sites far away from a water source, while a water-cooled CSP plant is modelled at sites near water resources. Since the type of condenser used has an effect on the performance of the power plant, as shown in the literature reviewed supra, this study, as part of its objectives, assessed both dry-cooled and water-cooled models at all of the six selected locations across the country to help in future planning for the sector. With the government of India's intention to cut down on the GHG emission intensity of the country's gross domestic product by 45% by 2030, and its long-term goal of reaching net zero by 2070 [40,41], we also evaluated the impact of the implementation of the CSP technology on the country's GHG reduction targets. This was accomplished by assessing the avoidable emissions that would have been generated if other conventional power plants relying on fossil fuels had been used to generate the same amount of electricity as that generated by the modelled CSP systems across all study sites. In addition, major potential barriers that hinder the development of such power plants in India are discussed in this paper using information reviewed from several research works.
