Thomas Built Buses Electric School Bus Powered by Proterra Technology Receives Full CARB and HVIP Certifications

Commercial production of the Saf-T-Liner C2 Jouley set for next year

High Point, N.C. – July 26, 2019 – Thomas Built Buses Inc. has received full California Air Resources Board (CARB) and Hybrid and Zero-Emission Truck and Bus Voucher Incentive Project (HVIP) certifications for its Type C electric bus, the Saf-T-Liner C2 Jouley powered by Proterra electric vehicle technology. This certification officially qualifies Jouley for state vouchers.

“With these certifications, we are one step closer to making electric school buses viable for the school bus market,” said Caley Edgerly, president and CEO of Thomas Built Buses. “While this milestone is worth celebrating, we continue to work with proven leaders in the industry like Proterra and our parent company Daimler Trucks North America to create the best product possible for the school bus market. Over the past few months, we’ve been piloting Jouley with individual drivers, engaging with school districts and local agencies to shape the future of our electric vehicle offerings. We are very excited about what Jouley has to offer today and where we are heading.”

In addition to the same vehicle quality, durability, performance, safety and comfort as the popular Saf-T-Liner® C2, Jouley offers quiet operation and zero emissions. The Jouley has 220 kWh of total energy capacity and can charge in about three hours with the Proterra DC charging system. Operating range can be up to 120 miles depending on various operating conditions. To date, Thomas Built Buses is the only OEM to offer a DC fast-charging power option.

“School buses are a great application for battery-electric vehicle technology and we’re excited to bring our industry-leading battery systems to the most popular Thomas Built Buses vehicle,” said Proterra CEO Ryan Popple. “In addition to greater efficiency and lower operating costs, electric school buses have zero tailpipe emissions, which eliminates exhaust emissions and benefits our communities and our children.”

The Saf-T-Liner C2 Jouley electric school bus, powered by Proterra electric vehicle technology, will be assembled in High Point, North Carolina, in Thomas Built Buses’ zero-waste-to-landfill facility. Proterra’s industry-leading battery systems are designed and manufactured in Burlingame, California. Electric school bus production for demonstration and innovation vehicles begins in 2019 and commercial production begins in 2020.
