WSDOT Zero Emission Vehicle Infrastructure Grants

WSDOT announced the availability of approximately $8 million in grant funding for the zero-emission vehicle infrastructure partnership (ZEVIP) program. The ZEVIP grant provides funding for installing new and upgraded EV charging equipment and hydrogen fueling infrastructure along priority corridors in Washington.

WSDOT seeks proposals that complete entire alternative fuel corridors, complete segments of corridors, or fill in gaps of existing corridors. Priority corridors include interstates, U.S. highways, and state routes.

  • For EV charging, stations should be located at least every 50 miles and within 1 travel mile of the priority corridor.
  • For hydrogen fueling, stations should be located at least every 150 miles and within 5 travel miles of the highway corridor.

The ZEVIP program website includes the grant notice and grant application guide, which details project requirements, instructions for submitting questions, and application requirements.

Eligible applicants include nonprofit organizations, tribes, and state and local government agencies such as cities, towns, counties, and districts. Potential grant recipients must have contributions from a private sector partner who stand to gain indirect value from the development of the project, such as automakers, retail stores, fueling stations, investor-owned utilities, or tourism stakeholders.

Eligible grant costs include site design, equipment purchases, electrical upgrades, installation, signage, operations, and maintenance. Projects must be operational and have final documentation submitted by June 30, 2023. Eligible projects are limited to:

  • New installations of EV charging infrastructure
    • For example, new DC fast-charging stations with at least four combined charging system (CCS) ports, supporting at least 150 kW per port simultaneous charging.
  • Upgrades to existing EV charging infrastructure
    • For example, adding new DC fast-charging stations with at least one CCS port, supporting at least 150kW per port charging, to a location that currently has only CHAdeMO plug(s). At least one CHAdeMO plug must remain where it is currently available.
  • New installations of hydrogen refueling infrastructure
    • For example, installation of a station capable of dispensing hydrogen at the mandatory H70-T40 (700 bar) that is designed, constructed, and operated in accordance with the latest standards for hydrogen refueling, including the National Fire Protection Association NFPA 2 Hydrogen Technologies Code and SAE J2601 fueling protocols for light-duty, gaseous hydrogen vehicles.

Important date

  • May 18 at 5:00 p.m.: Applications due.

Funding Results from Previous Opportunities

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.
