SamTrans Expands Electric Fleet Toward Zero-Emission Future
SamTrans operates 22 electric buses with 26 more ordered as part of $150M transition plan
SamTrans Adds Electric Buses to Fleet
SamTrans is expanding its battery-electric bus fleet as part of a long-term commitment to eliminate emissions by 2040, transit officials said. The San Mateo County agency currently operates 22 zero-emission buses with 26 more on order, representing about 7% of its 323-bus fleet. The transition involves an estimated $150 million investment funded through federal, state, and local sources, though officials haven't released a detailed breakdown of funding allocations.
California Mandate Drives Transition
The zero-emission initiative responds to California's Innovative Clean Transit regulation, which requires all transit agencies to transition to 100% zero-emission fleets. The state mandate requires all new bus purchases to be zero-emission starting in 2029, according to the California Air Resources Board. SamTrans began operating its first battery-electric buses in 2020, making it an early adopter among Bay Area transit agencies. The agency serves San Mateo County and portions of San Francisco and Palo Alto, though officials haven't specified which routes currently use electric buses.
Fleet Expansion Continues Through 2040
The 26 buses on order will increase SamTrans' zero-emission fleet to 48 vehicles once delivered, though officials didn't provide a timeline for when the new buses will enter service. The expansion is part of a phased approach to reach 100% zero-emission operations by 2040, according to information on the agency's website. Electric buses reduce greenhouse gas emissions by up to 70% compared to diesel buses over their lifetime, even accounting for electricity generation, according to the Union of Concerned Scientists. More than 5,000 electric buses are currently in operation or on order across the United States, according to the American Public Transportation Association.
Infrastructure Development Underway
The transition requires significant infrastructure investments including charging stations and maintenance facility upgrades, transit officials said. The agency is developing charging infrastructure at its operating facilities to support the growing electric fleet, though specific details about the number of charging stations or their locations weren't available. Officials said the infrastructure work is coordinated with the bus deliveries to ensure operational readiness.
Riders to See Quieter, Cleaner Service
The electric buses offer quieter operation and zero tailpipe emissions compared to diesel vehicles, improving air quality in communities throughout San Mateo County. Officials said the transition supports California's climate goals while maintaining reliable transit service. Riders can track real-time bus locations and service updates through Moovit, which provides current information for all SamTrans routes.
