1663090 - Converting a Conventional Bus Fleet to Electric Bus Fleet: Economics, Financing and Implementation

Abstract: The public transport market in most global cities is dominated by diesel buses, which can have significant adverse impacts on the environment and human health. To reach carbon neutrality, many public transport operators are attempting to replace their existing bus fleets with electric buses (EBs). This presentation discusses the key considerations in diesel bus fleet renewal to an electric bus fleet and the economics, finance and implementation issues involved. In particular, a generic bus replacement model to help public transit (PT) operators progressively renew their existing bus fleets so as to reach particular electrification goals within a given planning horizon was proposed. A case study for Singapore is presented on how Singapore PT operators and agencies has approached the economics and finance issues of the conversion and how the electric bus conversion implementation was performed by the National University of Singapore from 2021 to today.
