King County Metro is progressing toward a 100% zero-emission fleet by 2035. As existing diesel hybrid and older diesel-only buses are retired, Metro is replacing them with battery-electric buses. This program will transition Metro’s bases to accommodate battery-electric buses and install battery-electric bus charging stations. Metro is also developing future strategies and assessing the implementation of a larger, long-range electric bus fleet.

Working with King County Metro, Parametrix provided planning, engineering, cross-discipline/department coordination, power service and electrical engineering, sustainability assessments, cost estimating, scheduling, and project control services to facilitate the transition. To date, we have worked on bus rapid charging stations at the Eastgate Park-and-Ride, Redmond Transit Center, South Base, and Bellevue Base.
