The city of St. Louis, Missouri fleet plans to deploy 18 electric buses on the city’s busiest routes. Charging infrastructure for the 60-seat New Flyer buses will be provided by Swiss/Swedish electronics giant ABB.

St. Louis transit agency Metro Transit says it expects the e-buses to reduce carbon emissions by 100 to 160 tons per year, and to deliver up to $125,000 in maintenance savings and $400,000 in fuel savings over their 12-year lifespan.

ABB will provide 23 Buy America-compliant chargers, with a total of over 4.35 MW of charging capacity. ABB’s sequential charging system consists of 20 plug-in depot chargers, each with 150 kW of power, and three additional pantograph chargers. St. Louis’s buses can be fully charged in one hour. ABB says its fast-charging system easily integrates with existing transit schedules, so cities can switch to zero-emission buses without disrupting existing routes.
