Abstract
The cogency of dry cooled concentrated solar power (CSP) plant to assess its odds or accretion against the wet cooled plant is investigated in this work in hot and cold desert regions. Dry cooling proves to be a flipside option over the wet cooling system in locations where water resource is scarce. In the current work, the Andasol Parabolic trough CSP plant in Spain, which has 50 MWel nominal capacity with thermal energy storage (TES) hours of 7.5 at full load, is considered a reference plant. Simulation is performed for both wet and dry cooling options using Greenius software initially at the original plant location in order to validate results by considering actual plant values. Simulations were performed at Jodhpur and Leh with the help of the local metrological data. The parameters such as annual mean overall efficiency, levelized cost of electricity and water consumption with dry cooling for the reference plant at study site Jodhpur stand at 15.6%, 0.13 €/kW h LCOE, and 74,793 m3/year, respectively, whereas the same for wet cooled reference power plant yields 17%, 0.11 €/kWh LCOE (levelized cost of energy), and 5, 71, 365 m3/year at an annual energy yield of 163.24 GWhel net. The net electricity generation is high at Leh compared to Jodhpur, India. It is observed that dry cooling has given higher turbine efficiency except for the summer season due to very low ambient temperatures in Leh.
