Analysis of the Impact of Electric Heavy Equipment Use on Carbon Emission Reduction in the Indonesian Mining Sector

2025-11-13T01:59:45+00:00

Indonesia’s mining sector contributes significantly to national carbon emissions, primarily due to the intensive use of diesel-powered heavy equipment. Electrification of heavy machinery is increasingly viewed as a strategic approach to achieve the national Net Zero Emission (NZE) 2060 target. This paper presents a technical and environmental assessment of the carbon emission reduction potential achieved through the adoption of electric heavy equipment in mining operations. Using simulation-based modeling and comparative analysis of diesel versus electric energy consumption, this study quantifies the CO₂ reduction potential, energy cost savings, and return on investment. Results show that replacing a fleet of 100 diesel excavators with electric equivalents could reduce emissions by 15,800 tons CO₂ annually, corresponding to a 68% reduction compared to baseline conditions. The study concludes that large-scale electrification of mining equipment could play a pivotal role in Indonesia’s decarbonization roadmap, provided that renewable power integration and infrastructure readiness are improved

Analysis Analysis of Energy Consumption Performance in Oil and Gas Utility Systems Using Baseline and Specific Energy Consumption (SEC) Approaches

Abstract

This study examines the performance of energy consumption in utility systems within Indonesia’s oil and gas industry by employing a baseline model and the Specific Energy Consumption (SEC) indicator. Using national secondary data, the research develops an operational energy profile, evaluates the relationship between production levels and energy demand through linear regression, and assesses potential energy savings under various conservation scenarios. The analysis shows that monthly energy consumption remained within 305,000–321,000 kWh, reflecting the continuous nature of oil and gas operations. SEC values ranged from 28.0 to 28.4 kWh/BOE, indicating relatively consistent energy intensity. The baseline model produced a slope of 29.504 kWh/BOE and an R² of 0.94, confirming a strong correlation between production and energy use. Two conservation scenarios demonstrated annual savings of 179,109 kWh (moderate) and 554,419 kWh (aggressive). These findings demonstrate that baseline and SEC analyses serve as effective engineering tools for identifying inefficiencies and supporting energy optimization efforts in oil and gas facilities.
