Proterra Inc. announced a new collaboration to power ENC’s second-generation electric transit buses with Proterra’s battery technology.

Under a new, multiyear supply agreement, Proterra will supply its S-Series battery system to power ENC’s Axess Battery Electric Bus (EVO-BE) that will be available to transit agencies in 32-foot, 35-foot, and 40-foot models.

Delivery of the first Proterra Powered ENC Axess EVO-BEs is expected to begin in 2023.

“Public transit is at the forefront of electrification. Along with our partners at ENC, we’re delighted to help power this critical transformation with our battery technology and help bring cleaner air to cities and towns across the United States through zero-emission transportation,” said Chris Bailey, president of Proterra Powered & Energy.

ENC's EVO-BE and Axess Hydrogen Fuel Cell Electric Bus (EVO-FC) are also now in development. Both buses utilize the Axess platform and have advanced technology enabling longer ranges. 

The next-generation Axess EVO-BE will have 738 kWh of battery energy storage. The battery system and energy storage for the bus are supplied by Proterra Powered.

The next-generation Axess EVO-FC bus is designed to have a range up to 400 miles, based on application, and will build on the legacy of ENC’s Hydrogen Fuel Cell Electric bus.

Both the Axess EVO-BE and EVO-FC buses leverage a common structural platform, propulsion system and technologies, with over 90% commonality.

“ENC is excited to work with Proterra to provide the next-generation Axess EVO-BE with best-in-class battery technology as part of our ongoing focus on delivering zero-emission transportation solutions,” said Jason Moore, VP/GM, ENC.
