The mining industry, as one of the most energy-intensive an‎d emission-heavy sectors, plays a crucial role in the global transition toward sustainable development. In recent years, increasing environmental regulations an‎d economic constraints have highlighted the necessity of adopting low-carbon technologies in place of conventional systems. This study presents a techno-economic assessment of replacing diesel haul trucks with electric alternatives in the Sarcheshmeh Copper Mine, using the Net Present Value (NPV) method. The analysis comprehensively eva‎luates all cost components—including initial investment, energy, maintenance, an‎d operational downtime—over a 15-year period. Results indicate that electric haul trucks not only require a significantly lower initial investment but also reduce the total net present cost by approximately 60% compared to diesel trucks. Moreover, the share of energy-related expenses decreases from 27% in diesel trucks to about 12% in electric ones. Reduced unplanned downtime an‎d improved operational reliability further enhance the productivity of the electric option. Overall, the findings demonstrate the clear economic an‎d environmental superiority of electric haul trucks, suggesting that their adoption can serve as an effective strategy to lower life-cycle costs, improve energy efficiency, an‎d align with decarbonization goals in Iran’s mining sector.
