CSTEP developed the E-bus Depot Electrification Planning and Operational Tool (E-DEPOT) to support India’s electric bus (e-bus) transition under the Faster Adoption and Manufacturing of (Hybrid &) Electric Vehicles, or FAME, scheme. E-DEPOT assists state transport undertakings (STUs) and electricity DISCOMs in planning and managing the charging infrastructure required for depot-based e-bus operations. By providing evidence-based guidance on charging infrastructure, schedule viability, and cost estimation, E-DEPOT offers a robust planning framework to help cities scale up their e-bus deployment efforts efficiently and sustainably. The tool was showcased to STUs in Bengaluru, Kochi, Pune, and Chennai, where it generated significant interest because of its practical utility. CSTEP also took part in a capacity-building workshop and demonstrated the tool and its features to technical engineers from various STUs. The workshop equipped the engineers with the skills to utilise the tool for fleet electrification planning, tender preparation, and negotiations with e-bus operators.
