Environmental Assessment of Yazd Combined Cycle Power Plant Using the LCA Method

There exists pollution Emissions throughout the life cycle of power plants and Life Cycle Assessment Method, as one of the environmental impact assessment, can be useful in measuring and determining the amount and source of pollution Emissions during the electricity generation process. So In line with the importance of evaluating the effects of thermal power plants, the current study with the aim of Environmental impact assessment of electricity production in Yazd Combined Cycle Power Plant is done through Life Cycle Assessment Method (LCA). For this purpose, First of all, all materials, environmental resources, technologies used and emissions of various substances into the environment were estimated in 1 MWh of electricity per functional unit (inventory). Finally the impact of each of these inputs in the form of environmental indicators, were Quantitized. In this study we evaluated the environmental impact of electricity generation using Simapro8 software and CLM2000 evaluation method in 10 floors of potential effects. The results showed that the production of one megawatt hours of electricity in Yazd Combined Cycle Power Plant has a significant environmental impact In terms of offshore aquatic toxicity, acidification, depletion of fossil fuels and global warming. According to obtained information fossil fuels have created the most negative environmental impacts among other inputs. Global warming potential over the life cycle to producing 1 MWh of electricity in power plant of Yazd, In the process of operation of power plant using 623 kg And in the construction phase ./54 kilograms of carbon dioxide equivalent emissions were calculated.
