As part of a greater effort to battle climate change, the City of Seattle in 2019 committed to a 100% fossil-fuel-free fleet by 2030. Fleet electrification is a key component of this initiative that leverages the rapid technological advancements of the electric vehicle industry with Seattle’s access to low cost, green electricity. The Electric Vehicle Supply Equipment (EVSE) systemwide assesment anticipates the increased availability of electric duty fleet options, fast charging systems, increased vehicle driving ranges, and reduced vehicle ownership costs as key components for meeting City targets.
MAKERS and DKS Associates worked with Seattle’s Department of Finance and Administrative Services to document existing vehicle, charger, and fueling locations; develop planning-level costs to implement citywide charging infrastructure for 100% fleet electrification; identify power and fleet management strategies to reduce project costs; and develop a multi-year phased electrical infrastructure implementation strategy aligned with Seattle’s electric vehicle acquisition cycle.

The recommendation envisions charging infrastructure that provides electricity to each fleet vehicle where it parks and fast charging infrastructure at strategically-located key sites. An investment strategy is aligned to support fleet use and electric vehicle deployment, build resiliency and emergency response capacity into the system, and reduce overall cost, energy use, and greenhouse gas emissions.

This plan is intended for use in capital investment planning to allocate adequate and timely resources that will lead to the infrastructure needed to realize Seattle’s commitment to carbon neutrality.
