Abstract：Skid-mounted mobile substations are a new type of power equipment capable of rapid deployment, immediate operation, and mobility (towability). Strengthening the analysis and research on the carbon emissions throughout their entire life cycle holds significant importance for implementing the philosophy of green and low-carbon development, transitioning traditional substation construction models to eco-friendly and low-carbon practices, and advancing China’s dual-carbon goals (carbon peaking and carbon neutrality). This study employs the life cycle assessment (LCA) method to establish a carbon emission accounting boundary for skid-mounted mobile substations. By integrating their unique characteristics in production, manufacturing, construction, and operation, a life cycle carbon emission analysis model and computational workflow are developed. Taking a real project as a case study, data on carbon emissions across all life cycle stages are collected, calculated, and analyzed. The results provide a scientific reference for accurately understanding the carbon footprint of skid-mounted mobile substations throughout their life cycle.
