Energy in Oregon

​​​The Oregon Renewable Energy Siting Assessment will assess data and develop a mapping tool about renewable energy and transmission development in Oregon.  

The ORESA project is funded through a $1.1 million U.S. Department of Defense Office of Economic Adjustment grant awarded to the Oregon Department of Energy, working with the Department of Land Conservation & Development and Oregon State University's Institute for Natural Resources.

The project will collect data and informa​tion through assessments and a mapping tool to build an understanding of the opportunities and constraints that come with renewable energy and transmission development in Oregon. ​

We'll post regular updates about the project on th​is website. You can also sign up for email updates.

Project Purpose and Need

ORESA-Map.pngContinued renewable energy development is anticipated in Oregon in the coming decades, particularly solar energy, wind energy, and associated transmission line development (see drivers for renewable energy development in ODOE's 2018 Biennial Energy Report). ​

Developing these energy resources involves balancing issues related to natural resources, land use, environmental impacts, noise concerns, and cultural and archeological artifacts (among others) through processes at all levels of government – federal, state, and local.

Renewable energy and transmission projects also have effects on military training areas in Oregon and adjoining states, and may have a potential future effect on necessary military uses to prepare for future threats. Potential effects could include radar interference from wind facilities; low-level flight obstructions from tall structures such as wind turbines; electromagnetic interference from high-voltage transmission lines; and glint and glare from solar photovoltaic arrays near airfields. Meanwhile, there are parts of the state that have substantial renewable energy resources and facility potential. Local governments have benefitted from increased tax base and local economic growth through renewable energy project development.

This project will collect information about locations for current and future renewable energy and transmission development, and build an understanding of the opportunities and constraints that come with specific locations. The state can use this information to continue to support compatible renewable energy growth and economic development.

Project Summary

The project area covers the entire state of Oregon, including marine waters. The key elements of the project involve:

  • Compatibility assessments on renewable energy, military needs, and development opportunities and constraints that incorporate state and federal agency, Tribal, local government, military personnel, renewable energy developers, utilities, and additional stakeholder engagement and input. Assessments will be supported by consulting services secured via state procurement processes. Procurement opportunities will be listed under "Resources" in the right sidebar of this page.
  • Inter-jurisdictional collaboration across federal, state, and local entities to gain a deeper understanding of these issues through increased data and information.​
  • Reviewing and analyzing relevant state and local siting and permitting requirements and processes as they relate to military coordination and notification procedures. 
  • INR leading development of a mapping tool through GIS, which will include relevant compatibility data (like environmental or military considerations). The mapping tool will be part of the “Oregon Explorer​" online resource.
  • Sharing the assessment report and mapping tool with military personnel, renewable energy developers, utilities, Tribes, local governments, state agencies, stakeholders, and the public. 

Key Deliverables

  • ​Oregon Compatible Renewable Energy Siting Assessment Report
  • Oregon Compatible Renewable Energy Siting Mapping Tool and associated GIS data layers (hosted by INR)

These deliverables will raise awareness of renewable energy compatibility needs and will provide educational tools to identify potential project areas that have less conflict and could support economic development.
