Electric Vehicle Charging Infrastructure


WSDOT is launching a pilot 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 Pilot Program. WSDOT leveraged the funds with matching commitments 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. See the map of proposed highway charging locations.

How is the program funded?

The state legislature provided $1 million in seed funding to encourage private investment in EV fast charging along highway corridors. The funds are collected from plug-in electric vehicle drivers through a portion of the annual $150 electric vehicle registration fee that went into effect in July 2016.

When will additional program funding be available?

In order to continue, the program will need an appropriation in the transportation budget. If funded, the next round of grants would be for 2019-2021 projects with proposals due in Spring 2019. Applicants will have several weeks to submit proposals. After the closing date, an evaluation team will review the proposals and select projects for funding. Then, WSDOT and the grant recipients will negotiate statements of work and sign legal agreements.

Who is eligible for WSDOT's EV infrastructure grants?

If funding is continued, WSDOT would award 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. There are currently about 27,000 PEVs registered in Washington and the state needs more charging infrastructure to support the anticipated growth in EV adoption.

The Washington State Electric Vehicle Action Plan recommended developing an EV Infrastructure Program to encourage private investment in charging equipment to strengthen and expand the state's West Coast Electric Highway network.

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
