Santa Monica, in California, has launched a $56 million investment program to expand zero-emission bus infrastructure and fleet capacity.
The Santa Monica Department of Transportation held a ceremonial groundbreaking on April 9, 2026, marking the start of construction for Big Blue Bus’s zero-emission fleet expansion and associated charging infrastructure, according to a press note by the City of Santa Monica. The initiative is supported primarily by a $53.3 million allocation from the State of California’s Transit and Intercity Rail Capital Program and represents a key step in the agency’s transition toward a fully zero-emission fleet.
The project moves into the construction phase approximately 18 months after funding was secured, with infrastructure works already underway. The program combines vehicle procurement planning with depot electrification measures designed to support large-scale battery-electric bus operations.
Santa Monica towards deployment of 195 e-buses
Central to the project is the deployment of an overhead gantry charging system designed to support up to 195 buses. The system is intended to provide high-capacity, centralized charging at depot level, enabling operational continuity for a fully electrified fleet.
The infrastructure component includes electrical upgrades and integration of charging equipment within existing transit facilities. The development is structured to accommodate future fleet expansion as additional battery-electric buses are introduced into service.
Big Blue Bus currently operates 34 battery-electric buses. Additional vehicles are planned as part of ongoing procurement activities, aligned with the agency’s target of achieving full fleet electrification by 2032, as stated in the press note by the City of Santa Monica.
The total investment of $56 million covers both infrastructure and system upgrades. The funding structure is largely based on state-level financial support, with the Transit and Intercity Rail Capital Program providing the majority share.
The project includes construction, engineering, and electrical works, alongside workforce development components linked to zero-emission vehicle technologies. Training initiatives are included within the program scope to support operational and maintenance requirements associated with electric bus systems.
The electrification plan is integrated into Santa Monica’s Sustainable City Plan, which defines targets related to emissions reduction, air quality, and transport system modernization. The program also includes provisions for upgrading operational resilience through new energy systems and depot configurations.
The charging infrastructure under construction is dimensioned to support full fleet conversion, with completion milestones aligned to the 2032 target for systemwide zero-emission operations.
The project timeline includes ongoing construction phases and subsequent commissioning of charging systems, enabling progressive integration of electric buses into daily operations.
