Renewable energy sources are clean energy sources and have a much lower environmental impact than other energy sources. Energy production from biomass allows the storage of energy raw materials, unlike other renewable energy sources. Some factors and criteria affect the site selection of biomass power plants. Determining the significant levels of these conflicting criteria is vital for investors in choosing a biomass power generation facility location. Location selection of biomass power plants is a multi-criteria decision problem for decision makers. The relative importance of the criteria includes quantitative evaluations and is an uncertain process. In this study, a comprehensive literature study determined the criteria to be considered in selecting biomass energy production facility locations. The fuzzy analytical hierarchy process was used to determine the importance levels of the criteria to be used to select the bio-mass power plant establishment location.
