Wind Power in Oregon

In 2018:

              • ​3,383 MW of capacity
              • 44 operating facilities, 1 spans Oregon and W​ashington state line
              • 2,147 MW of additional capacity proposed, approved, or under review
              • Sites range from 1.6 to 300 MW
              • 13 largest facilities make up 69% of total capacity
              • 15 facilities, representing 590 MW, came online in 2009

Wind energy is captured when blowing wind moves turbine blades around a rotor, which turns a shaft that spins an electricity-producing generator.

Wind Industry

Oregon’s wind energy industry has developed mainly on the Columbia River Plateau in north central Oregon. Wind farms have also cropped up in eastern Oregon near Milton-Freewater and North Powder.

Through the first quarter of 2017, Oregon ranked 8th in the nation in installed wind capacity with 3,213 megawatts. (American Wind Energy Association)

Most wind projects consist of utility-scale wind turbines that each stand hundreds of feet in the air. Most of Oregon’s wind generation capacity comes mainly from large-scale wind projects that supply power directly to the electric grid. As of November 2018, Oregon has 34 wind projects of 10 MW or greater and another 10 facilities under 10 MW. Sherman County has 1,057 MW of capacity; Umatilla, Morrow, and Gilliam counties combined have 2,179 MW of capacity.

The state also has smaller-scale wind projects, including several community-owned projects consisting of a few mid-sized or large turbines, and numerous installations of small turbines that generate power on-site for homes and businesses. The industry for small turbines is less developed than the large, utility-scale wind industry.

With the increase of the Oregon Renewable Portfolio Standard to 50 percent renewable energy by 2040, more wind projects will likely be built in the state by independent developers and utilities.


Wind Projects

Developing wind projects is a complex process, particularly due to grid interconnection and transmission access issues. New utility-scale wind projects in Oregon will likely require significant transmission system investments. Small wind projects (<20 MW) have less impact on transmission but require complex system studies that may result in the need for expensive upgrades to the local grid.
