In this work we make the feasibility study of a 10 MW Dish/Stirling engine solar thermal plant for Juana Diaz, Puerto Rico, and Santo Domingo, Dominican Republic are done. The purpose of these studies is to determine the economic feasibility of this technology. Clearness index correlation by Erbs and the Collares-Pereira and Rabl equations are used to determine hourly estimations of direct solar radiation for Juana Diaz and Santo Domingo respectively. Realistic scenarios are developed by taking into account the renewable energy policies, financial parameters, incentives and cost for each location. These scenarios are simulated in Sola Advisor Model (SAM) obtaining the first year Power Purchase Agreement (PPA) price for an Internal Rate of Return (IRR) target of 7%. The first year PPA price was found to be 20.96c/kWh and 20.59c/kWh for Juana Diaz and Santo Domingo respectively.
