It’s time for clean, quiet transportation for all

Communities are growing and evolving, and with that, our transportation needs are changing. Now more than ever, we need safer, more reliable, and cleaner options. At Proterra, our mission is to advance EV technology to deliver the world’s best-performing commercial vehicles.

Proterra is a leader in the design and manufacture of zero-emission electric transit vehicles and EV technology solutions for commercial applications. Since 2004, Proterraregistered technology has been proven through more than 20 million service miles in heavy-duty applications.

From our own best-selling transit bus to electric school buses, delivery trucks, coach buses, and shuttles, Proterra battery technology is already powering commercial vehicles from world-class automakers and helping fleet operators reduce emissions while lowering operating costs.

As major cities convert to 100% electric fleets, Proterra vehicles have become the most popular electric buses on the road in North America. With more than a decade of experience delivering heavy-duty electric transit vehicles, Proterra has sold more than 1,000 electric buses to 130+ communities across 43 U.S. states and Canadian provinces.

To provide operators with a comprehensive set of products to deploy and scale their EV fleets, Proterra also offers a turn-key approach to delivering the complete energy ecosystem for commercial electric vehicles. In addition to high-power charging systems, Proterra Energy fleet solutions include charging infrastructure design, build, financing, operations, maintenance, and energy optimization.

With industry-leading powertrain technology, proven experience, comprehensive charging solutions, and unparalleled EV expertise, Proterra is the commercial vehicle electrification partner of choice for industry-leading manufacturers. Renowned automakers with Proterra Powered™ vehicles include Daimler’s Thomas Built Buses, Freightliner Custom Chassis Corporation, Van Hool, Optimal, and Bustech.

Together with our customers, we have prevented more than 100 million pounds of greenhouse gases from escaping into the atmosphere and avoided burning some six million gallons of fuel. From our state-of-the-art Silicon Valley R&D lab to manufacturing facilities in Southern California and South Carolina, Proterra is committed to powering the shift to 100% battery-electric fleets and delivering clean, quiet transportation for all.
