Proterra and UQM Technologies announce agreement

UQM Technologies, a developer of alternative energy technologies, announced that it has completed an agreement with Proterra Inc, a Golden, Colorado-based developer and manufacturer of electric and hybrid electric transit buses, to supply UQM PowerPhase 150 electric propulsion systems for use in Proterra’s all-composite fast charge battery electric transit buses.

The initial term of the supply agreement is one year. Deliveries totaling $627,500 are scheduled to begin in October. Additional deliveries permitted in the agreement during its one-year term could raise the total value of the contract to over $1 million.

Proterra has been developing and manufacturing energy-efficient commercial vehicle technologies since 2004.

Proterra’s latest transit bus, the zero emission all-electric EcoRide BE-35, holds 68 passengers (37 seated), and features a lightweight composite body. The bus also incorporates their TerraVolt fast charge energy storage system, which includes proprietary battery modules and packs and a battery management and energy optimization system that can be charged to full capacity in a matter of minutes using a Proterra on-route FastFill charging station.

“We are pleased to continue our multi-year relationship with Proterra as the propulsion system supplier for their state-of-the-art energy efficient transit buses as they begin the commercialization of this potentially game-changing vehicle,” said William G. Rankin, UQM Technologies’ Chairman and Chief Executive Officer.

“We expect transit operators to embrace this energy-efficient and environmentally-friendly bus over the next several years resulting in an expansion of our sales to Proterra as they grow their penetration of the transit bus market.”

“We are proud and excited to be working with UQM Technologies,” said Jeffrey Granato, President and CEO of Proterra. “Their PowerPhase propulsion system has proven to be highly reliable, which is critical to rolling out a new product, and its high efficiency contributes to the exceptional fuel economy of our EcoRide bus.”
