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 in June 2021 to identify the charging needs and gaps across Oregon.

Updates to TEINA report in 2022
The TEINA report was updated in August 2022 using a refined methodology to calculate charging port requirements for light-duty vehicles in 2025, 2030, and 2035 under all analysis scenarios. The major findings of the study are unchanged, illustrating the exponential growth needed for EV charging infrastructure in Oregon. Text, graphics and appendices in the report have been updated where necessary.

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 the Business as Usual scenario​. 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 (DAC). (In the PDF's below, Urban & Rural LDV are bundled together.)

​The heat maps for the Business as Usual scenario are included in the updated TEINA report and are included below. 

Heat maps for the disadvantaged communities use case show the additional number of chargers required in disadvantaged communities, beyond the estimates included in the urban and rural light-duty vehicle use cases (for the purposes of the heat maps, Urban & Rural Light Duty Vehicles are bundled together).
Heat maps for the micromobility use case show the reduced number of chargers required due to the transition of trips from light-duty vehicles to micromobility options such as bikes or scooters. For more information about the use case studies and three economic scenarios, please see the updated TEINA report​.​

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.  Study heat maps are avalible upon request.

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.

The refined methodology used to calculate charging port requirements provides a more accurate distinction between urban and rural areas, and their associated charging port requirements. The methodology also:
  • Distributes public Level 2 and DC Fast Charging ports based on the number of currently owned passenger vehicles.
  • Distributes workplace Level 2 ports based on the number of jobs. 
  • Corrects the “Corridor Light-Duty Vehicle” use case by removing duplicative counting of charging ports needed in each of the milestone years. 
Charts, figures, tables, and text have been revised throughout the report and the appendices to reflect the refined methodology, and to present the revised analysis results for these light-duty vehicle use cases: Urban, Rural, Corridor, Disadvantaged Communities, and Transportation Network Companies.

The use cases for Local Commercial and Industrial Vehicles, Transit and School Buses, and Long-Haul Trucking did not require updates and remain consistent with the original report.​

Advisory group 

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. The group will meet again in 2022 to consider updates and expansions of the TEINA work. See below for 2020-2021 archived and 2022 new meeting materials.

GO EV Chargeis a suite of online resources - including the Guide for Oregon EV Charging Deployment, the EV Infrastructure Planning Map and the TEINA Dashboard - to help Oregon planners and decision-makers deploy electric vehicle charging projects that are equitable, cost-effective and that meet community needs while supporting statewide goals for electrifying transportation. ODOT published these materials on August 31st, 2023. 

Hydrogen Pathway Study
Hydrogen may play a critical role in decarbonizing transportation. This study, published in Fall 2022, looked at how to prepare Oregon for hydrogen fuel cell electric vehicles over the next 15 years, and outlined a set of phased recommendations through 2035.

Electric Micromobility in OregonOregonians are using electric micromobility devices such as e-bikes, e-scooters, and others to get around. To better understand this rapidly growing sector, ODOT published its Electric Micromobility Study in early 2023.
