WSDOT Zero Emission Vehicle Infrastructure Partnership Grants

WSDOT’s ZEVIP grant provides funding for installing new and upgraded EV charging equipment and hydrogen fueling infrastructure along priority corridors in Washington. WSDOT published a Notice of Proposed Awards for projects that help complete entire alternative fuel corridors, complete segments of corridors, or fill in gaps of existing corridors. The ZEVIP notice of proposed awards for the 2021-2023 biennium represent an investment of $9.8 million in new and upgraded EV charging stations. For more information see the ZEVIP Notice of Grant Opportunity and Grant Application Guide (PDF 322 KB).

Funding Results from Previous Opportunities


The Washington State Department of Transportation (WSDOT) announced the Zero-emissions Access Program (ZAP) grant funding opportunity for 2021-2023. ZAP grants fund zero-emissions carshare pilot programs in underserved and low- to moderate-income communities that have limited access to public transportation or are in areas where emissions exceed state or federal standards.

The 13 projects awarded a total of $2.2 million for the 2021-2023 biennium are listed at the bottom of WSDOT’s ZAP Grant webpage.

Ecology administers the Clean Diesel Grants program. Funding is available for the following entities:

  • Air Quality Clean School Bus Grant Program 2022-2023 School bus owners that transport students to Central and Eastern Washington K-12 schools overseen by the Washington Office of Superintendent of Public Instruction (OSPI) for the 2021-2022 school year.
  • Air Quality Clean Diesel Grant Program 2022-2023 Cities, counties, public utility districts/co-ops, ports, transit authorities, school districts, state government, tribes, nonprofit organizations, tribes, and local clean air agencies.

Commerce Electrification of Transportation Systems (ETS) Program

Commerce is accepting grant applications for the Clean Energy Fund – Electrification of Transportation Systems (ETS) Grants program. PHASE ONE applications were due on September 15, 2022.

ETS grants provide funding for local governments, federally recognized Tribal governments, small utilities, and state agencies to integrate and manage electrical load from EVSE. Funding covers innovative projects that prepare communities to construct and/or expand EVSE through early-stage consultant studies, engineer designs, or direct capital asset investments and infrastructure upgrades.

WSDOT Green Transportation Capital Grants

New opportunities through this program are anticipated in summer 2022.

The Washington State Legislature Green Transportation Capital Grant (RCW 47.66.120) is awarded to transit agencies to fund capital projects to reduce the carbon intensity of the Washington transportation system. Examples include electrification of vehicle fleets, capital facilities to facilitate fleet electrification and/or hydrogen refueling and upgrades to electrical transmission and distribution systems.

These nine 2021-2023 Green Transportation Capital Grant winners were awarded nearly $16.5 million for July 2021 to June 2023.

Zero Emission Vehicle Infrastructure Partnerships

For the 2017-2019 program, WSDOT selected two projects through a competitive process to install 15 new EV charging stations near highway exits about 40 miles apart.

Electrification of Transportation

Commerce awarded $9.8 million for EV charging infrastructure through the Electrification of Transportation Systems Program to promote the continued transformation of the electric transportation market in Washington. Commerce prioritized projects in communities disproportionately impacted by climate change and pollution from transportation systems, many of which are often low-income and communities of color, and communities underserved by existing electric transportation infrastructure. The following proposed projects were conditionally awarded grants.

Workplace Charging

During fall 2019, Ecology offered grants to provide up to $2,250,000 to install Level 2 and direct current (DC) fast charging equipment for employee workplace charging at government-owned facilities in Washington. Eligible applicants included state, county, and city governments in Washington. The maximum amount for an individual grant award was set at $200,000.

Award recipients are listed below. Details of each project are not yet available.

Corridor Charging

In December 2019, Ecology opened a grant opportunity for DC fast chargers along high-traffic transportation corridors in Washington. About $4 million was available on a competitive basis to state, local, or tribal governments; private businesses and incorporated nonprofits. Ecology prioritized projects in communities disproportionately impacted by VW vehicle diesel pollution and those located within 1.5 miles of a high-traffic corridor. The maximum amount for an individual grant award is $600,000.

Over 50 entities submitted applications for nearly $4 million available to install DC fast chargers along Washington’s transportation corridors. Award recipients are listed below.

VW Settlement for Tribal Governments

In 2015 Volkswagen was cited by the U.S. Environmental Protection Agency and the California Air Resources Board for violating emissions standards by selling diesel vehicles equipped with "defeat devices." These devices allowed the cars to pass federal emissions tests, but during actual driving conditions they emitted significantly more air pollutants than allowed by the Clean Air Act. The federal government sued the company, and in 2016 VW settled the cases for $14.7 billion.

As part of the settlement, $2.8 billion was set aside for states and Tribes to fund diesel emission mitigation projects. $55 million of this money is earmarked for Tribes, in a trust called the "Volkswagen Diesel Emissions Environmental Mitigation Trust for Indian Tribe Beneficiaries," or just the "Tribal Trust." Any federally recognized Tribe can apply for funding from the Tribal Trust, which they can use to replace old, polluting diesel vehicles or equipment with new, cleaner models, or even install electric vehicle charging stations.

Electric School Buses

In one of the largest such investments in the country, the Washington Department of Ecology offered grants during fall 2019 for about $12 million statewide to help school districts purchase all-electric school buses. To help offset the cost difference between electric and diesel buses, Ecology would provide up to $325,000 per electric bus. Grant recipients could elect to use up to $50,000 of the $325,000 grant to help pay for the associated electric charging infrastructure. The results of this grant offering were announced in April 2020.

The grants fund the purchase of 40 new electric school buses in 22 districts around the state.

For more information, contact Mike Boyer, or 360-407-6863.
