New York MTA has leased five Proterra Catalyst E2 buses, which will go into service this December and initially serve routes in Brooklyn, Queens, and Manhattan. The lease program aims to evaluate the combined economic, environmental and performance benefits of deploying an all-electric bus fleet. Over the three-year lease, Proterra expects MTA to reduce 2,000 metric tons of greenhouse gas emissions and save approximately US$560,000 on maintenance and operating costs.
