Everett Transit/ Motor Vehicle Division Experiences by Tony Cademarti

  1. 1. Everett Transit / Motor Vehicle Division Experiences Tony Cademarti Fleet Program Manager City of Everett, Motor Vehicle Division/Everett Transit tcademarti@everettwa.gov
  2. 2. Choices That Were Made • Funding: FTA partnership grant with Proterra for 40 ft. electric buses • Depot Charging over On-Route Charging: • High cost and land ownership issues with on-route charging • University of Texas Austin study for extended range buses with depot charging
  3. 3. Why Choices Were Made • Need to replace a number of buses (six 1996-vintage Orion buses, six 2001-vintage Orion buses and three 2002-vintage Orion buses) in short order • Only grants available at the time were for electric buses (had experience with diesel-electric hybrid buses already) • Later, public declaration of transition to fully electric fleet of 36 electric buses by 2030 (50% electric by 2023- 18 buses)
  4. 4. How Implemented Solutions • Buses- Order process for buses with Proterra (at the time, Configurator) • Infrastructure- Work with local electric utility (SNOPUD), Bid process for installation of conduit, wiring, and chargers, lay groundwork for future expansion of charging infrastructure (extra conduit) • Chargers- switched from ChargePoint CPE250s to Proterra PCS and Dispenser system due to slowdown in production of CPE250s. • Training- Drivers (Train the Trainer-style) and Mechanics training by Proterra fly-away trainers • Fall Protection System- Miller SkyOrb
  5. 5. Lessons Learned • Not just another bus purchase- complete “system” • Shop design, i.e. in-ground lift design modification to work with independent suspension (possibly Proterra-only) • Need for “shop charger”- extra expense and infrastructure needs • New PPE required (arc-flash gear, EH-rated shoes/boots, etc.) • Unique parts/labor requirements, i.e. large-one piece windshield replacement • https://www.wired.com/story/electric-buses-havent-taken-over-world/ • Get ready to possibly hear “no” from manufacturer on desired configuration • Irregularities between units (quality issues) • Driver buy-in necessary (training, mindset, etc.)
  6. 6. Lessons Learned • Electromagnetic radiation concern by drivers (perception, not a real concern, as proven by testing) • Interference with AM radio reception during acceleration • Composite body and 20-ply tires- harsher ride (other buses in fleet have 16-ply tires and metal frames) • Charger unreliability (at first) • Need a dedicated Project Manager for initial purchase requirements- don’t split duties of infrastructure and bus procurement (Tony’s opinion) • Not an island- lessons learned from other agencies • Pierce Transit: https://www.piercetransit.org/electric-bus/ • King County Metro: https://kingcounty.gov/depts/transportation/metro/programs- projects/innovation-technology/zero-emission-fleet.aspx
