Pathfinder’s managers are currently developing two innovative projects in Wyoming. Please see detailed descriptions for these projects below.

Pathfinder Wind

Pathfinder Zephyr Wind

Pathfinder began working with ranchers in Platte and Laramie counties in 2009 to lease their wind rights and begin development of the Pathfinder Zephyr Wind project. Please see the Ranchers tab to learn more about these pioneers of the Pathfinder story. To date the project includes over 100 landowners and 150,000 privately-owned acres. We are conducting baseline habitat resource surveys and monitoring the wind resource with 15 met towers. This project, when completed, could be 2,000 – 3,000 MW.

In 2010, Pathfinder successfully bid to 70% of the capacity on the Zephyr Power Line, which will transport the project’s output to California and the Southwest. Zephyr is owned by a JV between Duke Energy and American Transmission Company (DATC). To learn more about DATC’s development and plans for Zephyr, please visit the project website at

Whirlwind I

In 2011 Pathfinder partnered with Whirlwind, LLC to develop the Whirlwind I project. Located near Rawlins, WY on private and federal land, this project is located near the proposed terminus of the TransWest Express line being developed by the Anschutz Corporation. Pathfinder is conducting baseline environmental assessments, monitoring the wind resource, and working through right-of-way permitting with the BLM. When the TransWest Express holds its open season, Whirlwind I will be positioned to bid on available capacity.

Sweetwater River Conservancy

Located on over 600,000 acres of ranches owned by Pathfinder, the Sweetwater River Conservancy will repair and preserve some of Wyoming and the West’s most critical habitats. Please visit the project’s website at to learn more.
