Proterra executives presenting, chairing Bus Roadeo event, leading subcommittees

GREENVILLE, S.C., April 24, 2013 – Proterra Inc, the leading provider of zero-emission commercial transit solutions and maker of the world's first battery-electric fast-charge transit bus, the EcoRide™, will showcase its transit leadership with several prominent roles at the upcoming American Public Transportation Association's (APTA's) Bus and Paratransit Conference, which runs from May 5-8 in Indianapolis.

Proterra executives Marc Gottschalk and Reuben Sarkar will highlight the company's thought leadership and advanced technology in several on-site sessions. Proterra's Senior Director of Business Development, Sarkar will address advanced vehicle technology in his presentation "Vision and Technology" from 8:00 to 9:30 a.m. Monday, May 6. With more than a decade of experience in advanced fuel-efficient transportation technologies, Sarkar has redesigned Proterra's engineering processes, managed the company's intellectual capital and created technology roadmaps to meet future industry needs.

Gottschalk will participate in two sessions. "The Future of Mass Transit is Now: The Path to Electric Buses," Monday, May 6 from 4:00 – 5:30 p.m., will draw from Proterra's considerable expertise in working with transit agencies to focus on strategies for successful EV bus purchases and deployments and why there is no need to wait to move forward. On Tuesday, May 7 from 9:45 – 11 a.m., Gottschalk will also co-present on the topic of clean fuels with Ralph Wilder of StarMetro, a Proterra customer located in Tallahassee, Fla., on the topic of clean fuels. Gottschalk's presentation will focus on building operationally and environmentally sustainable bus transit fleets.

The clean fuels event and several other committee sessions will be moderated by Proterra's Joshua Goldman, who chairs the APTA Clean Propulsion and Support Technology Committee.

Proterra battery-electric EcoRide buses will also be used to shuttle attendees to and from hotels and the convention center during the event. The only full-size battery-electric bus to ever pass Altoona testing, the EcoRide will also be on display during the Bus Roadeo. This high-profile event will be chaired by Proterra regional sales director Mike Hennessy, who joined Proterra last year after spending almost 30 years at the Chicago Transit Authority.

"The level of Proterra's presence and that of our customers at this key industry event is further evidence of our leadership in the electric bus and EV transit space," said Ian Shackleton, Proterra's vice president of sales and marketing. "We work tirelessly every day to create the technology and features transit agencies need to operate the most sustainable, cost-effective fleets possible. Our American-made buses meet all 2030 transit bus requirements now, and, since they have been thoroughly tested and finance packages are available, there is no need for transit agencies to wait. Truly, the future IS now, and we encourage everyone at APTA to come and experience our bus, talk to our team and customers and learn more about the EcoRide's unique environmental and value proposition at the show."
