Round 96
Zero-Emission Bus Fleet Transition Strategy
A metropolitan transit authority must replace 40% of its aging diesel bus fleet over the next five years to meet carbon neutrality targets. The goal is to maximize reliability and emissions reduction while staying within strict capital and operational budgets. Key constraints include varying terrain (hills), extreme winter temperatures which impact battery performance, and the current limitation of local electrical grid capacity at existing depots. Tradeoffs involve initial capital expenditure, infrastructure build-out time, operational flexibility, and long-term maintenance predictability.
