This research gives a region-based technology, economic, and environmental assessment of biomass power production in Yalova, Türkiye. The assessment includes an inventory of biomass resource data, how well the materials can be converted to electricity, assumptions regarding the transportation cost of biomass, and a financial analysis of the biomass project. The study will assess if a utility size biomass facility can be constructed in Yalova. In addition to the revised feasibility framework, a MATLAB-based optimization layer was introduced to determine the feedstock blend that minimizes delivered feedstock cost per unit of electricity under regional availability constraints. The compiled inventory indicates a total biomass potential of 610,498 t/year in Yalova, equivalent to 55,040 toe/year, with forestry residues forming the dominant resource class. The configurations of mixed waste stream (forest residues) resulted in the highest yield of electricity. Based in part on this data and optimizing the feedstock allocation by an annual period (to favour chicken litter/forest residues), the potential for generating electricity from a 220,000-tonne-per-annum biomass facility in Yalova is 40.37 GWh/year; approximately 0.184 MWh is produced for each tonne of feedstock delivered at a cost of 286.8 USD/MWh. As evidenced by these results, biomass energy is a technologically feasible means of contributing to emissions reductions in Yalova through implementing data-supported feedstock allocation methodologies that enhance the reliability of investment and operational planning.
