Özet:

Electrical energy is an indispensable need of continuity of life in today’s world. Therefore energy generation sources are one of the most important topics of countries, so that every country develops a strategy to use them efficiently. At this point, necessity of involving sustainability of energy sources in strategies makes hydropower energy become prominent. On the other hand, rapid increase in number of hydropower projects causes losing control of environmental effects of them. In this sense, a decision making methodology including environmental and social evaluation of run-of river hydropower plants is developed in the content of this study. In the scope of the study multi-criteria decision making (MCDM) analysis is used as decision making tool. For the MCDM analysis, ten environmental and social criteria are determined; for the aggregation of these criteria “and”, “or”, “Ordered Weighted Averaging” (OWA) and “Linear Weighted Averaging” (LWA) methods are used. Developed methodology is applied on five hydropower plants in Artvin/ Şavşat. Case study showed that “and” and “or” aggregation methods do not give chance to compare results and make no contribution to decision making process while OWA and LWA methods give useful results. Also, according to the case study implementation Gana is the most acceptable hydropower plant among five selected projects while Armutlu is the least acceptable one. Acceptability results of the case study implementation areas change between 0.17 and 0.72.
