Los Angeles wants to field a completely electric fleet of buses by 2030, and it just took a large step toward making that a reality. The city's Department of Transportation (which runs the largest municipal transit in the county) has acquired 25 of Proterra's smaller 35-foot Catalyst buses, all of which should arrive in 2019. That may not sound like much, but it's a significant chunk of the DOT's 359-bus fleet. The deal promises real savings, too -- it should eliminate 7.8 million lbs. of greenhouse gas emissions per year and save $11.2 million in energy and maintenance over 12 years.
