This document provides a feasibility analysis for a 100 MW solar thermal power plant. It discusses selecting a site with direct normal irradiation between 2200-2500 kWh/m2 in Southwest US states. The analysis justifies the selection of concentrating solar technology, heat transfer fluid and thermal energy storage. It evaluates costs using the System Advisor Model and optimizes the design variables like solar multiple and debt fraction to minimize levelized cost of energy. The optimized system configuration and results are described to assess feasibility.
