Public charging stations

Performance analysis

2022

To help ensure electric vehicles have ready access to power when needed, Washington has worked with its EV partners to increase the number of EV charging stations and ports. As of 2022, the state had:

  • 1,462 Level 2 charging stations (Level 2 Charging: 208-Volt to 240-Volt). Depending on the vehicle, this takes around eight hours to completely charge.
  • 226 Direct Current fast charging stations (Fast Charging: 400-Volt to 900-Volt). Fast chargers allow most vehicles to recharge in minutes as opposed to hours.

Washington state's Interagency Electric Vehicle Coordinating Council along with the National Electric Vehicle Infrastructure Formula Program are leveraging state and federal resources to the ensure electric vehicle incentives, infrastructure, and opportunities are available and accessible to everyone.

2021

To help ensure electric vehicles have ready access to power when needed, Washington has worked with its EV partners to increase the number of EV charging stations and ports. As of 2021, the state has:

  • 1,605 Level 2 electric vehicle supply equipment units with 3,404 ports (Level 2 Charging: 208-Volt to 240-Volt). Depending on the vehicle, this will take around eight hours to completely charge.
  • 217 Direct Current fast chargers with 726 ports (Fast Charging: 400-Volt to 900-Volt). Fast chargers allow most vehicles to recharge in minutes as opposed to hours.

In the past five years, the total number of charging ports (both Level 2 and DC fast chargers) has increased 131% from 1,790 to 4,130.

Because not all electric vehicles use the same type of fast charger to plug in and recharge, WSDOT works with partners to ensure a variety is offered. Increased EV adoption is expected to help the state progress toward its goals of reducing greenhouse gases, protecting public health and the environment, and promoting economic growth.

2020

To help ensure electric vehicles have ready access to power when needed, Washington has worked with its EV partners to increase the number of EV charging stations and ports. The state has:

  • 1,262 Level 2 electric vehicle supply equipment units with 2,528 ports, and
  • 181 Direct Current fast chargers with 591 ports

In the past five years, the total number of charging ports (both Level 2 and DC fast chargers) has increased 133% from 1,337 to 3,119.

Because not all electric vehicles use the same type of fast charger to plug in and recharge, WSDOT works with partners to ensure a wide variety is offered at locations across the state. Increased EV adoption is expected to help the state progress toward its goals of reducing greenhouse gases, protecting public health and the environment, and promoting economic growth.

2019

WSDOT completes fast charging network to the Tri-Cities

EV drivers traveling from Seattle or Spokane to the Tri-Cities on I-90, I-82 and US 395 can now access public fast chargers every 40 miles along their routes. WSDOT invested about $2.5 million in grants and partnership matching funds into new EV charging infrastructure during the 2017-2019 biennium through WSDOT's Electric Vehicle Infrastructure Partnerships Program.

EVIPP contributed to the installation of fast charging equipment within a mile of highway exits in 15 communities throughout Washington state. Nine new stations in eastern Washington bridged the charging gap between the Tri-Cities and I-90 to both the west and the northeast of Tri-Cities. Six new charging sites on the I-5 corridor strengthened the existing fast charging network. These new stations and other charging infrastructure investments increased the number of public charging ports in Washington 206%, from 949 in 2015 to 2,905 in 2019.

The EVIPP grant funding encouraged private sector investment by sharing costs for finding sites, equipment purchases, electrical upgrades, installation, operations and maintenance. WSDOT aims to continue expanding the state's network of EV charging stations along major highway corridors in Washington

2018

Washington's fast charge network expanding to new corridors

WSDOT has awarded $1 million in grants through its Electric Vehicle Infrastructure Partnerships Program, which in addition to $1.5 million in partnership matching funds, is investing about $2.5 million into new EV infrastructure during the 2017-2019 biennium. These funds are being used to install 15 new charging locations near highway exits about 40 miles apart along I-5, I-90, I-82, US 395 and I-182, expanding the EV network even further. The number of public charging ports in Washington has increased 282% from 629 in 2013 to 2,401 in 2018.

EVIPP grant funding pays for siting, equipment purchases, electrical upgrades, installation, operations and maintenance. WSDOT continues to work with partners across the state—such as Energy Northwest, Greenlots, EV4, Forth, EVgo, local utilities, host site business and car dealerships—to expand its network of electric vehicle charging stations along major highway corridors in Washington.
