Transportation Electrification Infrastructure Needs Analysis

The TEINA study highlights gaps in the electric vehicle charging infrastructure and proposes solutions to help accelerate widespread transportation electrification in Oregon.

The ODOT Climate Office, in partnership with the Oregon Department of Energy, completed the Transportation Electrification Infrastructure Needs Analysis study to identify the charging needs and gaps across Oregon.

Heat maps: The TEINA study produced several heat maps representing needed charging ports for several use cases and scenarios. See the below drop-down menu ‘Study heat maps’ for PDF’s of each map. 

About the study

Convenient, accessible charging infrastructure is a critical driver in accelerating the widespread adoption of electric vehicles (EVs) and other types of electric transportation (such as electric buses, delivery vans, freight trucks and e-bikes) and to achieve the state's greenhouse gas emissions reduction goals, particularly in the transportation sector.

Governor Brown's Executive Order 20-04 directed ODOT to lead the study, in collaboration with other agencies and entities.


  • ​Highlight charging infrastructure needs for light-duty zero-emission vehicles (ZEVs) in support of the statewide adoption targets for 2025, 2030, and 2035 included in Senate Bill 1044​.
  • Provide a near-term and long-term high-level overview of the charging infrastructure needs for other vehicle classes and use types, ranging from medium and heavy-duty trucks and buses to e-bikes and e-scooters.
  • Develop a vision of the charging infrastructure needed to meet Oregon's transportation electrification goals over the next 15 years.
  • Assess the unique needs for charging infrastructure to support transportation electrification in all parts of the state.
  • Propose policy options and identify ways to expand charging infrastructure in Oregon to accelerate statewide transportation electrification.
  • Position Oregon to develop an overall ZEV charging infrastructure strategy that can inform development of EV charging infrastructure in Oregon and support the state in meeting its transportation electrification and greenhouse gas emissions reduction goals.​


The TEINA study produced heat maps to help identify where chargers are needed for several use cases and scenarios. The maps include four time intervals: 2020, 2025, 2030, and 2035.

The nine use cases: urban light-duty vehicles; rural light-duty vehicles; corridor light-duty vehicles; local commercial and industrial vehicles; transit and school buses; transportation network companies; long-haul trucking; micromobility; and disadvantaged communities. (In the PDF's below, Urban & Rural LDV are bundled together.)

The three scenarios: business as usual; rapid recovery; and slow recovery. The scenarios refer to the U.S. economy post the COVID-19 pandemic. “Business as usual" pretends the pandemic never happened, in order to produce a baseline to measure the recovery scenarios against. “Rapid recovery" assumes the economy recovers from the pandemic downturn by the end of 2021. “Slow recovery" assumes the pandemic downturn persists through 2024, then the economy slowly recovers through 2035.

There are two special categories of heat maps: “reduced" and “additional." Both categories were created with assumptions that in some scenarios, users can share chargers. Sharing affects the final data, so standalone maps were created to reflect that. There's a more specific explanation of what both categories mean on the individual “reduced" and “additional" heat maps.  ​

Electrification goals per SB 1044

  • 2020: 50,000 registered ZEVs in Oregon.
  • 2025: 250,000 registered ZEVs and 25% of new state agency light-duty fleet vehicle purchases and leases are ZEVs, where feasible.
  • 2029: all new state agency light-duty fleet vehicle purchases and leases are ZEVs, where feasible.
  • 2030: at least 25% of registered vehicles are ZEVs and at least 50% of new vehicles sold annually are ZEVs.
  • 2035: at least 90% of new vehicles sold annually are ZEVs.

Advisory group - archive

We created an advisory group to guide the TEINA study. The  group's members represent utilities, local governments, nonprofit groups and the auto industry.

The group met four times between November 2020 and May 2021. See below for archived meeting materials.
