Miami-Dade County has announced a new fleet electrification project and is acquiring 42 Proterra Inc. ZX5+ electric transit buses, featuring a total of 19 megawatt-hours of battery storage capacity, along with plans to install 75 Proterra chargers across three bus depots. The first electric buses are slated to be delivered in 2022. At nine megawatts of power, the project is also one of the largest fleet charging installations in North America.

Designed and manufactured in the U.S., Proterra’s electric transit buses are equipped with the company’s battery technology systems. Proterra battery-electric buses feature zero tailpipe emissions. The company says its fleet of electric transit buses have displaced over 100 million pounds of CO2 tailpipe emissions.

In addition to the company’s Proterra Transit and Proterra Powered business units, Proterra Energy offers a turn-key approach to delivering the complete energy ecosystem for heavy-duty electric fleets through charging infrastructure design, build, financing, operations, maintenance and energy optimization, the company says.
