The San Mateo County Transit District (SamTrans) has ordered 10 new 40-foot Proterra Catalyst E2 electric buses. SamTrans operates 77 routes throughout San Mateo County, including Proterra’s home city of Burlingame. The agency has set a goal of electrifying its entire 312-bus fleet by 2033.
The 10 Proterra Catalysts will begin service in 2019, replacing 10 diesel buses. Over their 12-year lifetime, the e-buses are expected to deliver cost savings on maintenance and operations of nearly $4.5 million.
Proterra’s new Burlingame battery production facility is currently ramping up production to meet demand, and can produce over 500 MWh of E2 battery packs yearly. Proterra claims that its E2 battery packs represent the heavy-duty industry’s highest pack-level energy density, at 160 Wh/kg and 260 Wh/L.
