Innovative Partnerships - Electric Vehicle Charging Infrastructure


WSDOT manages a program to strengthen and expand the West Coast Electric Highway network by deploying electric vehicle (EV) fast charging infrastructure along highway corridors in Washington state.

Grant Awards

Through a competitive application process, WSDOT awarded $1 million in grants for the 2017-2019 Electric Vehicle Infrastructure Partnerships Program (EVIPP) of about $1.5 million, for a total investment of about $2.5 million.

The funds are helping to install a total of 15 new charging locations near highway exits about 40 miles apart along I-5, I-90, and I-82/US-395/I-182. Grant funding is used for siting, equipment purchases, electrical upgrades, installation, operations and maintenance. All new locations include equipment serving all plug in cars with Level 2 equipment and duel fast chargers with both standards.

How is the program funded?

Based on the success of the pilot, the state legislature included the program in the Green Transportation Package, HB 2042, and provided $1 million per year for ten years to continue the program. This is one of the initiatives funded through a new $75 annual registration renewal fee for plug in electric and hybrid vehicles. Other funds collected from the new fee are used for sales tax incentives on the purchase of new and used plug in electric vehicles

When will additional program funding be available?

Depending on funding availability, WSDOT aims to request proposals in 2020.

What about refueling stations for hydrogen fuel cell vehicles?

The legislature broadened the program to support the deployment of clean alternative fuel vehicle charging and refueling infrastructure that is supported by private financing. In addition to electric vehicle charging infrastructure, funds may be used for investing in hydrogen fuel cell refueling stations. WSDOT will work with stakeholders to revise the program rules to add the option to fund hydrogen fueling stations for future investments.

Who is eligible for WSDOT's EV infrastructure grants?

WSDOT awards grants to non-profit organizations and to state and local government agencies such as cities, towns, counties, transit agencies and tribes. Potential grant recipients are strongly encouraged to partner with private sector companies to develop and implement projects.

What are the priority corridors for investment?

EV charging is needed at retail businesses along I-5, I-90, US 2, US 101, I-82, US 395 and other key corridors in Washington State.

What other investments are underway for highway electric vehicle charging?

WSDOT is taking a careful and thoughtful approach to building a program that will maximize the state's investment. WSDOT is exploring several opportunities to leverage the state funds to bolster the EV Infrastructure Pilot Program:

Why is the state investing in EV charging infrastructure?

The state's Results Washington goal is to have 50,000 plug-in electric vehicles (PEVs) on our roads by 2020 and we have already reached that goal. The Department of Licensing publishes electric vehicle registration numbers monthly on the state's open data portal. The sales tax incentives on the purchase of new and used plug in electric vehicles will likely drive that number up. The state needs more charging infrastructure to support the current EV drivers and the anticipated growth in EV adoption.

The Joint Legislative Transportation Committee (JTC) conducted a study on Electric Vehicle Supply Equipment (EVSE) Business Models. The committee found that, until there are more electric vehicles on our roads, the state needs to provide incentives to encourage investment in charging infrastructure.

Why do we need charging along highway corridors?

Fully electrified transportation corridors—with stations every 40 to 70 miles on long-distance routes—will give EV drivers confidence that recharging is available when they travel between communities, make long-distance road trips, and commute to work. Knowing that charging is easy and convenient helps encourage residents and businesses to buy and drive EVs.

How does Washington benefit from electric vehicles?

Vehicles that run on electricity drawn from the state's clean-energy mix of hydro, wind and solar energy are far cleaner than petroleum-dependent cars. In Washington, the transportation sector accounts for nearly half of the state's greenhouse gas emissions. Encouraging a shift from petroleum-based fuels to fuels with low or no carbon emissions contributes to a set of strategies needed to reduce the transportation sector's impact on the environment.

How do citizens benefit from electric vehicles?

Drivers of electric vehicles benefit by:

  • having more vehicle choices
  • saving money on gas and vehicle maintenance
  • reducing dependency on foreign oil
  • helping meet greenhouse gas reduction goals
  • creating green technology jobs
