As transit agencies scale up zero-emission service, depot charging infrastructure is becoming one of the most critical pieces of the puzzle—especially in high-ridership systems where space and turnaround time are tight. CTE member Heliox, A Siemens Business, is working with King County Metro Transit on a pilot deployment of the Heliox Flex Pro™ 480 kW charging system in Seattle. The pilot is part of King County Metro’s broader transition to zero-emission bus service and will help assess high-power charging in a compact footprint, with flexibility to scale as fleet needs evolve. The system includes a single power cabinet that can support up to six dispensers. The project reflects broader industry efforts to better understand how charging infrastructure can support operational reliability, depot constraints, and long-term fleet electrification planning.

High‑ridership agencies like King County Metro have to keep buses moving through already‑busy depots as they electrify. They need to do this without creating new bottlenecks or risking service reliability. King County Metro, which serves Seattle and 34 surrounding cities, is piloting the Heliox Flex Pro™ system with Heliox, A Siemens Business. Heliox Flex Pro™ has a compact 12 sq. ft. footprint and delivers up to 480 kW of power. Designed for space‑constrained transit bases, it supports fast turnarounds in limited real estate. Paired with an overhead pantograph, it can charge battery‑electric buses from 20% to 80% in about an hour, helping keep vehicles in service and riders on schedule as the zero‑emission fleet grows. The system supports high‑power opportunity charging and can connect to multiple depot pantographs or plug‑in dispensers for off‑shift charging. Together, these capabilities give agencies like King County Metro a scalable, future‑ready path as they electrify their networks. #KingCountyMetro #ElectricBuses #TransitFleets #ChargingInfrastructure
