The Seattle Department of Transportation (SDOT) is working with other city departments and regional partners to support EV adoption in shared mobility services. This case study as well as updates to the EVSE Roadmap for Shared Mobility Hubs highlight the evolution of this work throughout the course of the project and innovative ways in which the city has addressed roadblocks. This case study also provides a brief overview of Seattle’s role as the project’s prime recipient.
State of the EV and Shared Mobility Space in Seattle
Seattle is seeking to accelerate transportation electrification efforts and benefits from a supportive policy environment. Launched in 2017, the city’s Drive Clean Seattle initiative sets goals of electrifying 30 percent of all vehicles by 2030. This initiative also calls for municipal fleet electrification, electric utility investment in charging infrastructure, and increased public-private partnerships to accelerate transportation electrification. In May 2019, the city also required all new buildings with off-street parking to be “EV-ready” by installing charging infrastructure. This forms the basis of SDOT’s close partnership with Seattle City Light (City Light), the municipal electric utility serving the city, and shared goals to reach citywide carbon neutrality by 2050.
As a part of Drive Clean Seattle, the city also implemented the Electric Vehicle Charging the Right-of-Way (EVCROW) pilot. This pilot permitted the installation of EV charging stations at public curbside locations. Some of City Light’s charging stations deployed for this project will be deployed using the EVCROW permit pilot.
Project Structure and Core Goals
Seattle’s goals have adapted to shifts in the local EV market since the project proposal was approved in the fall of 2017. This section highlights the dynamic nature of the project and adaptations undertaken by Seattle in order to advance transportation electrification and raise EV awareness among TNC drivers in the region. First the initial goals and scope of the project will be covered followed by the current goals and scope.
Initial Goals and Scope
Seattle identified charging infrastructure and EV awareness gaps as key barriers to EV adoption among TNC drivers in the project proposal. To address these challenges, the city originally sought to explore the impact of hub-based fast charging on shared mobility electrification. In addition to charging infrastructure deployment and outreach efforts, Seattle originally sought to work closely with vehicle providers to test whether EV access was also an important barrier for ride-hail electrification. In the project proposal, the city initially set a target to deploy a total of 40 DC fast charging stations and 60 Level 2 charging stations as well as 200 carshare and private EVs throughout the city.
In coordination with outreach partners, Seattle sought to convene regular meetings between the stakeholders in the EV outreach space to ensure TNC drivers were connected with information that could help them make the switch to EVs.
The city designed their program to incorporate community feedback, address air pollution, improve access to transit, and reduce barriers to EV adoption. In addition to these broader focus areas, Seattle sought to leverage their strong public transit system to address the integration of shared mobility services. The hub-based approach and partner-led efforts to electrify shared mobility was designed to improve access and connectivity to public transit while reducing the dependency on private vehicle transport.
Current Goals and Scope
Seattle remains committed to charging infrastructure deployment and EV outreach despite unexpected project changes that have led to some restructuring of the original implementation plan. The withdrawal of carshare service ReachNow as a partner in the project due to the end of their service in the region led to the removal of the original project strategy to deploy electric vehicles. Tasks related to deploying vehicles have been adjusted to supporting the adoption of EVs in shared mobility services. The withdrawal of Eluminocity as a partner led to the removal of their commitment for charging station installations. City Light will lead charging station deployment and remains committed to installing 20 DC Fast Chargers for this project. Current goals include the following:
Seattle has gone beyond looking at shared mobility hubs for their charging stations and has included locations within City Light’s service area, which reaches beyond City of Seattle boundaries, for site location options. The city’s EV Dynamic Siting Tool provides guidance for charging station deployments. The tool converges on 11 metrics for site assessment, drawing on feedback provided by TNC drivers and other stakeholders to create an overall prioritization score. The tool also includes Equity and Environmental Justice as one of its considerations to help guide equitable EVSE deployments. The EV Dynamic Siting Tool also informed Seattle’s EVSE Roadmap for Shared Mobility (“EVSE Roadmap”). The EVSE Roadmap provides an implementation plan for regional partners. Seattle revised its EVSE Roadmap to reflect strategy shifts in the first quarter of 2020. For more on Seattle’s EVSE Dynamic Siting Tool, site selection process, implementation plan, partner roles, and evaluation plan, see the EVSE Roadmap for Shared Mobility.
As the project manager, Seattle is also working to ensure that all EV Shared Mobility Project partners make necessary changes following shifts and restructuring of the overall project and maximize shared learning across all cities involved.
Partnership Building and Contracting
* Indicates partners that have withdrawn from the project
Throughout the project, Seattle partners have leveraged existing relationships across different city departments to accelerate the deployment of charging infrastructure. For example, chargers installed as of June 2020 are on SDOT property (public right-of-way), Seattle City Light property, and Seattle Parks and Recreation property.
Challenges around partnership building have largely arisen from business developments and shifts stemming from activities outside of the EV Shared Mobility Project. The decision of original project partners Eluminocity and ReachNow to withdraw from the project were precipitated by the ending of service in the Seattle market. These developments led Seattle to shift their focus away from vehicle provision to assessing the impact of EV charging station access and supportive outreach and engagement among ride-hail drivers to increase EV shared mobility adoption.
Partnership has remained more consistent on the outreach front. City Light is responsible community outreach around EVSE deployment sites, in partnership with SDOT and OSE. According to the updated EVSE Roadmap, City Light works “to integrate community feedback in deployment plans, secure appropriate permits and host agreements with site owners and install and maintain” charging infrastructure once it is deployed. WWCC is leading direct engagement with TNC drivers and is supported by OSE which is conducting citywide stakeholder convenings with shared mobility providers. Feedback from these meetings and contribution from other partners has been integrated into the design of WWCC’s outreach campaign.
Data Collection and Analysis Strategy
To determine the impact of the newly deployed charging infrastructure, SDOT will work closely with City Light to collect charging station use data from stations installed through the project. One challenge will be identifying the ride-hail driver’s use of these stations since they will be open to the public. Atlas Public Policy is working to finalize data sharing agreements with the National Renewable Energy Laboratory to devise ways to analyze TNC driver charging behavior across all EV Shared Mobility project partners.
To measure the impact on EV adoption in shared mobility services, the city plans to leverage existing for-hire driver information to identify the current number of ride-hail drivers with EVs and assess EV adoption in for-hire fleets throughout the course of the project.
Outreach metrics have been standardized across the different EV Shared Mobility projects and the city will work with WWCC, the outreach lead, to ensure that the outcomes of their campaign are reflected in this shared framework.
Seattle is also working with Atlas Public Policy to coordinate quarterly reporting with project partners to ensure that metrics are being collected regularly to support requirements established by the DOE.
