TriMet in Portland, Oregon, is making significant strides in expanding its zero-emission bus fleet. The addition of 24 battery electric buses from GILLIG on Line 9-Powell represents a commitment to sustainable public transportation. These buses, equipped with six lithium-ion battery packs and an extended range, aim to enhance operational efficiency. The incorporation of 24 charging stations at the Powell Facility reflects TriMet's dedication to supporting electric bus operations. Furthermore, plans to introduce 14 hydrogen fuel cell electric buses along the 82nd Avenue corridor by the end of the decade showcase TriMet's forward-thinking approach. Federal grants totaling $64 million will facilitate the transition to a more sustainable bus fleet, including infrastructure upgrades and training programs. The move towards zero-emission buses aligns with TriMet's goal to achieve a fully electric fleet by 2040, signifying a positive step towards environmental sustainability and enhanced public transportation in the Portland metropolitan area.
