Electric Buses Are Headed to North Carolina

Riders in Greensboro, North Carolina, will be among the first in the Tarheel State to board electric buses. The city's transit authority is buying four 40-foot Proterra electric buses for around $3.84 million. 

The buses will replace fossil fuel buses that are being retired. Over their 12-year lifetime, the new electric buses are expected to save more than $1.7 million in O&M costs. 

To recharge the buses, the city is building a fast-charge battery station. It will be able to charge a bus battery in six to 12 minutes as the bus drops off riders and waits for new ones to board. 

Proterra says its batteries have a range of 350 miles and can be charged with plug-in chargers or overhead charging systems. The drivetrain includes a 220kW peak permanent magnet drive motor and a 2-speed auto-shift EV transmission. 

It's no race car, but the bus can go from 0-20 mph in 4.5 seconds. Its powertrain also includes regenerative braking technology.

Proterra designs and manufactures zero-emission heavy-duty vehicles. To date, it has sold more than 480 vehicles to 60 different municipal, university, airport and commercial transit agencies in 25 states. 

The vehicles are designed, engineered and manufactured in the U.S., with around three-quarters of its components sourced from U.S. locations. Corporate offices are in Silicon Valley, and the company has manufacturing facilities in South Carolina and Los Angeles.
