Introduction & Aim: Environmental pollutions are the side effects of industrial activities which put the environment in danger. On the other hand, by growing the population and increasing the electricity usage in the country, it’s necessary to construct new power plants. Power plants were prioritized based on different criteria. In this research based on the environmental, social and economical dimention , Kahak wind powerplant (the biggest wind powerplant) and Pakdasht Combined cycle powerplant (the biggest combined cycle powerplant in Iran) were studied. Methods: In this research, Multi criteria decision making methods such as AHP and Topsis were used .to select the priority of the power plants. These two are the most important and optimal decision making methods .Results: Among the five environmental criteria which were chosen by experts, water (weight of 0.451) was placed in the first rank . Other criteria like weather (weight of 0.223), social and economical effects (weight of 0.120), soil (weight of 0.114) and other environmental effects (weight of .081) were placed in second to fifth rank.Discussion & conclusion: As a result , based on the expert’s opinion ( Delphis` panel) construction of more suitable powerplants as Wind cycle powerplants are more suitable than combined cycle .because of less environmental pollution and degredation and also are moved toward environmental sustainability.
