- In-Depot Charging Design
Foothill Transit’s commitment to electrification is among the first projects of this scale in the nation, designed to be completed a decade ahead of the State of California’s mandate that all transit vehicles be “zero emission” by 2040. The transit agency serves 22 cities in Los Angeles County, supporting 39 routes with more than 350 buses.
Our team provided consultative planning and conceptual engineering services for the effort in partnership with ebusplan, Greenlots and AMMA Transit Planning.
Developing a fleet electrification roadmap required a thoughtful and thorough consideration of a number of variables. The team modeled the energy consumption of more than 350 bus routes to determine the capability of all-electric buses to complete each route and outlined the resultant charging needs at two centralized depots. Major considerations included:
- Charging equipment to reliably provide a full day’s worth of charge overnight.
- Optimizing equipment layout given limited space at each depot.
- Utility coordination to ensure significant power demands could be met.
While this was a landmark shift for the transit agency, the transition needed to remain nearly imperceptible to the riders who count on Foothill Transit buses every day to get where they need to be. Our team delivered a comprehensive plan that helped Foothill Transit move toward 100% electrification while minimizing impacts to their current operations and level of service.
