San Francisco International Airport to add 6 Proterra electric buses

Proterra announced that the San Francisco International Airport (SFO) purchased six 40-foot Catalyst® E2 electric buses and three 60 kW Proterra plug-in chargers, joining a growing list of airports across North America transitioning to electric buses for airport ground transportation. The new battery-electric bus fleet will reduce Bay Area emissions and support SFO’s goal of carbon neutrality by 2021 while cutting its bus operating costs.

As one of the fastest-growing airports in the U.S., SFO has ambitious plans in place to reduce its carbon footprint. SFO’s Five-Year Strategic Plan sets goals of carbon neutrality across airport-controlled operations by 2021 and the reduction of greenhouse gas emissions by 50% from a 1990 baseline.

Part of that plan includes the creation of a Clean Vehicle Policy to promote the adoption and deployment of low-emission vehicles by both airport departments and ground transportation providers. The new battery-electric Proterra Catalyst buses will replace six diesel buses in its current operating fleet and will eliminate more than 23 million pounds of greenhouse gas tailpipe emissions over the 12-year life of the vehicles. SFO expects to purchase additional battery-electric buses to replace its CNG vehicles, for a greener, more modern fleet.

The new electric buses will integrate batteries that are designed and manufactured down the street from the airport at Proterra’s Silicon Valley headquarters in Burlingame, California. With 440 kWh of battery capacity on board, the buses will be part of SFO’s fleet that currently provides buses to shuttle passengers between the terminals, long-term parking garages, and other airport locations along daily routes.
