Abstract
The Burning of fossil fuels, such as coal, fuel oil, natural gas, and diesel in power sector, has become one of the major sources of air pollutants, namely COX, NOX and SOX. These are thought to adversely affect the environment and human health. This paper assesses the external cost of electricity production from fossil fuel power plants in Iran using the Extern-E study. In addition, the future of average amount of emissions and their external cost was predicted according to the development of Iran’s power generation system. Investigation of power generation planning in Iran from 2013 to 2023 shows that the average emissions of PM10, SO2, CO, and CO2 will reduce by 26.7%, 54.2%, 65.4%, and 20%, respectively, in fossil power plants. Moreover, it was predicted that the average external cost of power generation in 2023 would decrease up to 28.9%, 27.6%, and 23.1% in low, medium, and high scenarios, respectively. Moreover, analyzing the trend of Iran’s electricity exportation and considering the prospect of Iran’s energy sector, we claim that substitution of old gas power plants with high throughput combined cycle will help achieve the goal of Iran’s power generation development more sustainably.
Highlights
World gross electricity production by an average annual growth rate of 3.4% has almost triplicated during 1974 and 2015, reaches to around 28000 terawatt hour (TWh) in 2019
This study showed that by enhancing governmental support from renewable sources, the total external cost of power generation could decrease (Štreimikienė, 2020)
The external cost of emission such as CO2, NOx, SO2, Carbon monoxide (CO), and PM10 from power generation in Iran was investigated in this study
Summary
World gross electricity production by an average annual growth rate of 3.4% has almost triplicated during 1974 and 2015, reaches to around 28000 terawatt hour (TWh) in 2019. The assessment of health impacts and external costs of a natural gas power plant in Iran was performed using the ExternE method (Fouladi Fard et al, 2016). The study investigated the impact of trading electricity on the external cost of power generation Those countries that relied on electricity imports were outsourcing the grid’s stability to other countries and induced environmental damage beyond their borders. Environmental damage is an inevitable output of an energy system that depends on fossil fuel sources, the impact of this damage on the countries’ electricity trading plan has not been considered seriously. The aim of the present is to quantify the environmental damage through a power generation system that highly depends on fossil fuels and investigates its impact on the electricity exportation plan. The results will clarify the real amount of government’s benefit from generating and exporting electricity to the neighborhood countries
