The transition towards sustainable energy in the construction machinery sector is gaining momentum due to the urgent need to reduce greenhouse gas emissions and operational costs. Despite the benefits of electric construction machinery, challenges such as high initial investment costs, infrastructure requirements, and the practicality of battery swapping systems hinder widespread adoption. Understanding the economic feasibility and practical implications of implementing battery swapping in different construction scenarios is crucial for facilitating this transition. This study contributes to the existing body of knowledge by conducting a detailed Total Cost of Ownership (TCO) analysis for various energy sources —diesel, built-in batteries, and battery swapping systems — in two distinct construction settings: Big Quarry and Small Construction site. It provides a comparative evaluation of these options, highlighting the economic and environmental benefits of battery swapping. A comprehensive TCO analysis was performed, encompassing costs related to machine purchase, fuel/electricity consumption, maintenance, and infrastructure. Sensitivity analyses were conducted to identify critical cost drivers and assess the impact of fluctuating fuel and battery prices on the overall cost-effectiveness of each energy solution. The findings indicate that battery swapping is the most cost-effective option across both construction sites, offering substantial savings compared to diesel and built-in batteries. Sensitivity analyses further showed that even with increased battery costs, electric machinery maintained stable economic performance, underscoring its viability as a sustainable alternative.
