Electric City and Transit Buses

Finding

Transit electrification is limited by depot power and route blocks, not by bus range: the expensive decisions are the size of the depot's grid connection and whether to buy smaller packs plus terminal pantographs

A 12 m battery bus in city service uses roughly 1.0-1.5 kWh per km, rising toward 2 kWh per km with electric heating in a cold winter. A 250 km block at 1.4 kWh per km needs 350 kWh; with a 20% reserve and allowance for battery aging, that points to the 450-600 kWh packs New Flyer, Gillig, Mercedes and MAN now sell.

Depot power is the bottleneck. A depot of 100 buses each drawing 150 kW at the end of service is a 15 MW load; spreading 100 recharges of about 400 kWh across a six-hour overnight window still needs about 6.7 MW, which few legacy garages have. Agencies answer with managed charging software that staggers start times by block, on-site battery storage that shaves the peak and the demand charge, and new utility service that can take two to four years. Opportunity charging trades pack size for street infrastructure: 300-450 kW roof or inverted pantographs at terminals (SAE J3105 in North America, the OppCharge interface in Europe) let a 150-300 kWh bus run all day on 5-10 minute top-ups, but each terminal needs land, a utility feed and uptime that matches the schedule.

The US market is a short list. New Flyer's Xcelsior CHARGE NG and Gillig's Low Floor Battery Electric take most orders, both Buy America compliant; Phoenix Motor builds the former Proterra ZX5 in Greenville, South Carolina, at low volume; Nova Bus sells the LFSe+ in Canada only after leaving the US market. BYD builds buses in Lancaster, California, but cannot sell to agencies using FTA money. Fuel-cell buses (New Flyer Xcelsior CHARGE FC, Solaris Urbino 12 hydrogen, Wrightbus StreetDeck Hydroliner) serve agencies with long blocks and no room for depot power, at a fuel cost that has kept them niche.

Europe buys from everyone. Yutong was the top seller in the first half of 2026, Solaris, Iveco and Heuliez, MAN and Mercedes hold the home market, Wrightbus and Alexander Dennis build double-deckers for the UK, and Volvo now sources its 7900 Electric from MCV in Egypt. Autonomy is entering through the busway: Connecticut's CTfastrak has run a New Flyer Xcelsior AV pilot, and Karsan's driverless e-ATAK runs public routes in Norway, while Stagecoach's CAVForth autonomous bus in Scotland ended for lack of riders.
