The Washington, D.C. Circulator system has deployed 14 battery-electric Proterra Catalyst E2 buses. The District’s electric bus rollout will make it the largest electric bus fleet in the DC region, the current largest electric fleet on the East Coast, and one of the largest electric bus fleets nationwide.

Formed through a partnership between the District Department of Transportation (DDOT), Washington Metropolitan Area Transit Authority (WMATA) and DC Surface Transit (DCST), the D.C. Circulator system services six distinct routes across Washington, D.C. and Rosslyn, VA.

Currently, the Circulator provides door-to-door transportation to more than 25 museums, monuments and memorials along the National Mall. Providing more than five millions trips each year, the Circulator only costs $1 to ride, ensuring that residents, commuters, and visitors alike have access to fast and affordable transportation.

With 14 Catalyst E2 buses, the D.C. Circulator will displace more than 88,900 gallons of diesel per year, and eliminate more than 243,980 pounds of CO₂ emissions annually. Over their 12-year lifetime, the 14 Proterra buses will result in fuel and maintenance cost savings of more than $6 million. The Catalyst E2 also holds the world record for an electric vehicle travelling 1,013.76 miles on a single charge.
