Zero Emission Vehicle Infrastructure Partnerships

WSDOT manages an alternative fuel vehicle charging and refueling infrastructure program known as Zero Emission Vehicle Infrastructure Partnerships (ZEVIP). The program strengthens and expands the West Coast Green Highway network by deploying zero emission vehicle (ZEV) infrastructure, that is supported by private financing, along highway corridors in Washington state 

Feedback Wanted on Draft Program Rules

In 2019, the legislature made the program permanent and broadened it to include hydrogen fuel cell refueling infrastructure that is supported by private financing. WSDOT is revising the rules for the program to align with the legislation. 

Please review the revised draft rules for the program and provide your comments to by October 27, 2020. 

A public hearing to adopt the rules will be held:

November 5, 2020, at 2:50 p.m.
Transportation Building, Nisqually Conference Room
310 Maple Park Avenue S.E.
Olympia, WA 98504

Grant Funded Projects

Through a competitive process, WSDOT awarded $1 million in grants for the 2017-2019 program to leverage about $1.5 million in matching funds, for a total investment of about $2.5 million. The funds helped to install a total of 15 new electric vehicle charging stations near highway exits about 40 miles apart along I-5, I-90, and I-82/US-395/I-182. Grant funding was used for siting, equipment purchases, electrical upgrades, installation, operations, and maintenance. The new locations include dual fast chargers with connectors for both national standards and Level 2 equipment serving most makes and models of plug-in electric cars. 

Eastern Washington Project

Project Lead: Energy Northwest on behalf of Electric Vehicle Infrastructure Transportation Alliance (EVITA) in collaboration with Greenlots and EV4.
$405,000 State Grant
$1,071,000 Total Project
This project provides a network of DC fast chargers in 9 communities along I-82, I-182, US 395, and I-90. The network bridged a charging gap between Tri-Cities and I-90 to both the west and north-east of Tri-Cities. New stations are in Cle Elum, Connell, Ellensburg, Kennewick, Moses Lake, Pasco, Prosser, Richland, and Yakima.

I-5 Corridor Project

Project Lead: Forth in collaboration with EVgo
$595,000 State Grant
$1,461,689 Total Project
New electric vehicle fast charging infrastructure along I-5 by provides dual charging stations to fill gaps and provide redundancy. New stations are in Bellingham, Chehalis, DuPont, Lynnwood, SeaTac, and Tacoma.

When will the next round of funding be available?

WSDOT plans to issue a request for proposals for the next round once the revised program rules are approved.

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 about refueling stations for hydrogen fuel cell vehicles?

In addition to electric vehicle charging infrastructure, state funds may be used for investing in hydrogen fuel cell refueling stations. WSDOT is working with stakeholders to revise the program rules to make hydrogen fueling stations eligible for grant funding.

What are the priority corridors for investment?

Priority corridors for electric vehicle charging infrastructure include Interstate 5, Interstate 82, Interstate 90, Interstate 405, U.S. Route 2, U.S. Route 12, U.S. Route 101, U.S. Route 395, and roadways connecting midsize communities and major tourist destinations. 

Priority corridors for hydrogen refueling stations include, but are not limited to, Interstate 5, Interstate 82, Interstate 90, U.S. Route 2, U.S. Route 97, State Route 7, and State Route 167. These priority corridors may be updated over time and bidders may propose other corridors for consideration.

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. The majority of funds collected from this new fee are used for sales tax incentives on the purchase of new and used plug in electric vehicles

What other investments are underway for alternative fuel vehicle infrastructure along Washington’s roadways?

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 ZEV Infrastructure Partnerships (ZEVIP) program:

  • Successfully obtained national designation of I-5, I-82, I-90 and US 101 as Electric Vehicle Charging Corridors through the Federal Highway Administration (FHWA) Alternative Fuel Corridor Designation Program.
  • Submitted Pacific Northwest ZEV Investment Proposals for Cycles 1, 2 and 3 for Volkswagen's $2 billion Electrify America Investment Program. Electrify America is building electric vehicle charging in the greater Seattle area and along I-5 and I-90 in Washington and plans to expand the highway charging to the Olympic Peninsula.
  • Coordinating with Ecology on approximately $16 million available over ten years for light duty electric vehicle charging in Washington through the federal Volkswagen settlement.
  • Completing a research project with the University of Washington on a modeling tool to support investment decisions on highway corridor charging.

Why is the state investing in ZEV infrastructure?

Washington state reached its Results Washington goal to have 50,000 plug-in electric vehicles (PEV) on our roads by 2020 and zero emission vehicle adoption continues to grow. 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 zero emission vehicles will likely drive sales and use of these vehicles. The state needs more charging infrastructure to support the current EV drivers and the anticipated growth in alternative fuel vehicle 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 ZEV Infrastructure along highway corridors?

Electric vehicle charging and hydrogen refueling stations at key intervals along state and federal highway corridors are needed to support interurban, interstate, and interregional travel for clean alternative fuel vehicles. Publicly available charging and refueling sites give alternative fuel vehicle drivers confidence that they can travel between communities, make long-distance commutes, and go on road trips. Knowing that infrastructure is accessible and convenient helps encourage residents and businesses to buy and drive clean cars.

How does Washington benefit from zero emission 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 zero emission 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
  • contributing to the creation of green technology jobs
