A new report identifies key actions for Seattle City Light to take to expand its market presence and strategic vision as electric vehicle adoption grows. Actions include the provision of 20 direct current fast chargers (DCFCs) that Seattle City Light is already deploying in areas underserved by private-sector charging networks.
But with battery pack costs expected to fall to an average $150 per kilowatt-hour this year, it will soon be economically advantageous for numerous market segments to switch to electric vehicles. Seattle City Light knew that it would need to start preparing for a surge in electricity demand on its system, so it partnered with RMI to assess the demand that transportation electrification would impose on its system.
RMI identified several state- and citywide efforts that will continue to drive strong demand for vehicle charging infrastructure in Seattle:
- Washington state’s passenger vehicle market continues to see strong growth, with the share of EVs having increased 31% from 2016 to 2017. To support this, private charging developers, with support from the Washington State Department of Transportation and the Seattle Department of Transportation, are investing heavily in EV charging stations.
- Seattle’s major public transit agency, King County Metro (Metro), has established a goal to fully electrify its fleet of more than 1,400 buses by 2040. To date, Metro operates 11 all-electric buses and plans to procure 120 more by 2020.
- In 2017, the Port of Seattle (the Port) established a strategic objective to be the greenest, most efficient port in North America, including carbon neutrality by 2050 on both direct and indirect sources of greenhouse gas emissions. Supporting this effort, the Port has implemented a Clean Truck program, as a partner in the Northwest Seaport Alliance.
- The City of Seattle has set an ambitious target of 30% EV adoption, along with a commitment to a fossil-fuel-free municipal fleet, both by 2030.
- Recently passed state legislation (HB 2042) extended a tax credit for electric vehicles, enabled utilities to invest in electric vehicle charging infrastructure, provided funding for electric car sharing in low-income communities, provided grants for transit agencies to transition to electric buses, and funded additional fast charging stations across the state.
The report’s key recommendations for Seattle City Light include:
- Invest in charging infrastructure, including utility-owned DCFCs and grid upgrades needed to support private-sector DCFC networks, to make fast charging available to all residents.
- Support deployment of nonutility-owned DCFCs for ridesharing drivers and for residents of multiunit dwellings and underserved communities.
- Provide incentives and technical expertise for installing Level 2 chargers at residences and workplaces.
- Explore and pilot electricity rates that make electric transportation cost-competitive with transportation by conventional vehicles, and that make it possible to operate profitable private-sector DCFC networks.
- Improve customer service to offer streamlined and transparent interconnection and service upgrade processes for new charging stations.
- Develop digital content to help customers make informed decisions about buying EVs.
- Establish standards to encourage “smart charging” during low-cost hours and to support the use of EVs as flexible grid assets.
- Prepare for heavy-duty electrification, and support the electrification needs of partner agencies such as Metro and the Port, by offering responsive rates, incentives, grid infrastructure, technology demonstration and siting analysis.
- Prepare to support urban fleet and freight operators and develop packaged charging solutions, including financing, make-ready investments, smart charging and incentives for charging depots.
