Taking public transit into a more sustainable future with ZEBs

Straddling the Gold Country and High Sierra regions of California, the County of Calaveras has seen a lot of changes—and climate change is the latest concern. Looking for a more sustainable public transit solution, Calaveras Transit Agency (CTA) engaged us to develop a study and provide a Zero Emission Bus (ZEB) Rollout Plan for fixed-route revenue fleet conversion by 2040. By identifying a comprehensive and sustainable plan for CTA that complies with the CARB (California Air Resources Board) regulation, our study findings support the ZEB rollout plan.

Our analysis considers the operational and financial impacts of a full fleet conversion by examining the difference in the capital and operating costs of new battery electric bus technology versus a fossil-fuel powered bus. We looked at the capital cost of associated ZEB infrastructure, the capital cost of rehabilitation or purchase of interim non-ZEB vehicles and infrastructure, and the overall operating cost impacts—the financial analysis considered lifetime and life cycle costs. Of special significance was the need for a rigorous analysis of fleet scheduling and operations with the various range limitations of ZEB buses.

With this plan for a zero emission bus fleet, we’re helping CTA curb emissions in their community.
