Aligning Golden Gate Transit with California efforts to meet federal air quality standards and climate protection goals

Golden Gate Transit (GGT) needed to develop a comprehensive zero emission bus (ZEB) rollout plan to comply with California Air Resources Board’s (CARB) Innovative Clean Transit mandate. However, 54 percent of GGT’s fleet are motor coach buses which brought a challenge as this is a relatively undefined segment in terms of ZEB.

Working with GGT to create a plan to submit for CARB approval, we calculated the fleet’s total power requirements, fueling and charging scheduling windows, and cost of ownership. By conducting an in-depth analysis of the agency’s four facilities and existing routes, we helped GGT determine the optimal fleet composition of battery electric buses and/or hydrogen fuel cell electric buses. We are also conducting a survey of all ZEB alternatives in the market, assisting with resiliency planning, and helping identify technology options for maximizing the use of renewable energy.

To support proper implementation, we’re also assisting with training plan and schedule development for ZEB operators and maintenance and repair staff. Once complete, the final ZEB rollout plan will help inform priorities, key decision points, and other critical considerations.
