The California Air Resources Board has set goals for all public transit fleets in the state to be zero-emission by 2040. To meet that target, transit agencies are required to begin shifting to battery electric and fuel cell buses now. In 2019, the Schatz Energy Research Center developed a model for the system-wide electrification of Humboldt County's public transit. This Battery Electric Bus Optimization (BEBOP) model cost-optimizes a one-to-one replacement of all buses on existing routes, generates recommendations for charging infrastructure, and calculates the electricity consumption profiles for each station. This model significantly expands the available development tools for rural planning agencies.
