Proterra Announces the Largest-Ever U.S. Order of Altoona-Tested Electric Buses

Current Proterra customer Foothill Transit to buy 12 new buses to fully electrify a major route

GREENVILLE, S.C., September 5, 2013 – Proterra Inc., the leading provider of zero-emission battery electric transit solutions, has completed the largest-ever U.S. sale of Altoona-tested heavy-duty electric buses to Foothill Transit, a joint powers authority of 22 member cities in the San Gabriel and Pomona Valleys in Southern California. In 2011, Foothill Transit became the first transit agency in the United States to use on-route charge electric buses by purchasing and operating Proterra buses. Based on strong performance and return on investment of those vehicles, the agency has decided to purchase an additional 12 buses from Proterra to completely electrify its 291 route, which travels between LaVerne and Pomona.


Although popular throughout the United States for reduced cost of ownership and sustainability, zero-emission electric buses are of particular interest in California, where there are many environmental non-attainment zones and California Air Resource Board (CARB) regulations in play.

"The Foothill Transit order is a clear vote of confidence and confirmation that Proterra buses truly deliver the lowest total cost of ownership and smallest carbon footprint of any transit bus on the market," said Garrett Mikita, president and chief executive officer, Proterra Inc. "Foothill Transit was our first customer and the first U.S. transit agency to go electric with on-route charging, so we are thrilled that they have seen the value of expanding their electric fleet and will use Proterra buses to do so."

The Foothill Transit sale is the latest in a wave of new orders for Proterra, with the company's last three sales to transit systems coming from repeat customers. Recently, StarMetro of Tallahassee purchased an additional three EV buses from Proterra, increasing their EV fleet size to five, and the Worcester Regional Transit Authority in Massachusetts doubled its initial three bus order to six.

"We had high hopes when we first made the decision to use these innovative fast-charge EV buses," said Foothill Transit executive director, Doran Barnes. "These electric buses have more than delivered on our expectations in terms of cost savings and sustainability. We're looking forward to launching ourand our region'sfirst all-electric bus line. This is the future of zero-emission buses, and we're proud to be on board."

To keep pace with this growing demand, Proterra has doubled its production workforce, installed a second production line, added a second shift and grown its sales staff significantly.

RBI Solar - Dahlia Has You Covered

What if you could maximize the Ground Coverage Ratio (GCR) on your next project and not have to worry about the complicated variables that come with a tracker system? With a low tilt and clearance design, Dahlia® has the highest GCR of any fixed-tilt system in the marketplace. The system is available in three tilt options (7.5, 10 and 12.5 degrees) and designed to accommodate any sized PV module. The lightweight system is engineered with fewer components, several of which are shipped to job sites pre-assembled. This design feature reduces freight costs and rapidly trims the amount of on-site installation time required to complete construction. Maximizing PV coverage on a site can lead to an increase of production, which creates greater financial return for project owners. Over 100 MW of Dahlia® projects have been deployed across the United States, in regions of variable snow and wind loads. How much can Dahlia® cover and save you on your next project?
