'Cost-effective solutions for clean transporation'

Advanced technology vehicle manufacturer Mobile Energy Solutions, LLC, announced today that the company's name is changing to Proterra. Proterra means 'for the earth' in Latin, which addresses the company's customers' needs for clean energy transportation and reduced reliance on fossil fuels.

Based in Golden, Colorado, Proterra manufactures the world's first hybrid- and all-electric, all-composite body transit vehicles built from the ground up to offer dramatic improvements in fuel efficiency while generating ultra-low or no emissions. Proterra offers all-battery and battery dominant vehicles using an array of auxiliary power units, including bio-diesel, gasoline, compressed natural gas, and hydrogen fuel cells.

"Proterra's mission is producing the world's most energy efficient transit vehicles while offering the lowest lifetime cost of ownership," said President Jeff Granato. "Our vehicles are the right choice for these times of skyrocketing fuel costs and economic uncertainty.

The company was founded in 2004 by the principals who designed, engineered and manufactured the 36 EcoMark 1, 45' CNG-fueled hybrid-electric shuttle buses built for Denver's 16th St. Mall. These buses are now in their eighth year of revenue service, and have carried over 130 million passengers. Dale Hill, Proterra's Chief Executive Officer, added, "The EcoMark buses produce only a fraction of the pollution of a comparably sized conventional bus while carrying twice as many passengers. This fleet continues to be the largest and most successful alternative fueled hybrid vehicle electric bus fleet in the world."
