The investment aims to support the transition to a fully zero-emission fleet by 2032.At the core of the project is the deployment of new battery-electric buses alongside the construction of advanced charging infrastructure. Plans include an overhead gantry charging system designed to support up to 195 buses, enabling efficient depot charging at scale. The agency currently operates 34 battery-electric buses, with further vehicles set to be added in the coming years.Santa Monica officials said construction began just 18 months after funding was secured, highlighting the pace of implementation. California Secretary of Transportation Toks Omishakin described the project as a model for execution, stating: “This is what it looks like when investment turns into impact.”The electrification programme is expected to deliver a range of operational and environmental benefits. By replacing diesel vehicles with battery-electric buses, the city aims to reduce greenhouse gas emissions, improve local air quality and lower noise levels. Electrification is also expected to reduce long-term fuel and maintenance costs while strengthening system resilience through modernised energy infrastructure.Santa Monica Mayor Caroline Torosis emphasised the broader impact of the transition, stating: “This is what progress looks like. It’s practical, it’s measurable and it’s moving us forward.”She added that reliable and accessible public transport supports a ‘healthier, more sustainable city.’From an operational perspective, the project is designed to transform the delivery of public transport services.“This project represents more than an infrastructure investment—it’s a transformation of how we deliver transit service,” said Anuj Gupta, Director of the Santa Monica Department of Transportation. “We’re building the foundation for a cleaner, more efficient system that benefits our riders, our workforce and our community.”santamonica.gov, smdp.com
