A new multigeneration system was proposed without cooling facilities or fossil fuel burning. The system produces power, cooling, heating, freshwater, hydrogen, and oxygen. Here, an economic evaluation of the system is performed to analyze its economic feasibility. Total annual costs (TAC), annual operating costs (AOC), and annualized capital costs (ACC) are determined using a nonlinear mathematical model. The model is developed based on the purchased equipment cost of the components, labor, insurance, engineering, and contingency costs. The results showed that TAC of the system coupled with 20,648 m3/d WWTP was 260,928 $ that 53 % belonged to AOC and 47 % to ACC.
