Diesel school buses significantly contribute to greenhouse gas emissions and air pollution, adversely affecting the climate and community health. This project, in partnership with Calgary's Southland Transportation, targets the efficient scaling of electric school buses at a depot, addressing a critical knowledge gap in charging infrastructure and management. Utilizing real-world data from over 50 buses, a practical, cost-effective charging infrastructure electrification blueprint encompassing various scenarios and their associated capital and operational costs will be developed. This initiative promises not only to showcase the technological and economic feasibility of electric bus fleet expansion but also to expedite an equitable industry-wide adoption.
