The environmental and economic life cycle assessment of a real-life run-of-the-river type hydroelectricity power plant in Turkey has been performed by considering the following stages: raw material acquisition, construction (including waste management), and transportation. CCaLC2 software and CML2001 methodology were used to calculate six different environmental impacts, whereas the economic impact was chosen as the levelized cost of electricity (LCOE). Functional unit was 1 MWh of electricity generated. The environmental impacts were found to be on average 95% lower than those of the Turkish grid, and the LCOE was calculated as $58.4/MWh. This outcome is understandable considering the high share of fossil fuels, especially low-quality lignite, in Turkish electricity grid. The results were compared to those of a similar study conducted abroad and all the impacts were found to have the same order of magnitude, proving that this study is methodologically consistent with the literature. The main conclusion is that hydroelectricity produced by run-of-the-river type plants in Turkey is environmentally friendly and economically viable compared to grid electricity. This is the first study in Turkey on the life cycle impact analysis of hydroelectricity and one of the few studies that consider economic and environmental factors simultaneously.

土耳其径流式水力发电厂的环境和经济生命周期评估

土耳其一个真实的河流型水力发电厂的环境和经济生命周期评估已通过考虑以下阶段进行:原材料采购、建设(包括废物管理)和运输。CCaLC2 软件和 CML2001 方法用于计算六种不同的环境影响,而经济影响被选为平准化电力成本 (LCOE)。功能单位为 1 MWh 发电量。发现环境影响平均比土耳其电网低 95%,计算得出的 LCOE 为 58.4 美元/兆瓦时。考虑到土耳其电网中化石燃料的高比例,尤其是劣质褐煤,这一结果是可以理解的。将结果与国外进行的类似研究进行比较,发现所有影响具有相同的数量级,证明该研究在方法上与文献一致。主要结论是,与电网电力相比,土耳其河流型电厂生产的水力发电对环境友好且经济可行。这是土耳其第一项关于水电生命周期影响分析的研究,也是少数同时考虑经济和环境因素的研究之一。主要结论是,与电网电力相比,土耳其河流型电厂生产的水力发电对环境友好且经济可行。这是土耳其第一项关于水电生命周期影响分析的研究,也是少数同时考虑经济和环境因素的研究之一。
