Apex Clean Energy is exploring the potential to develop Great Pathfinder Wind in Boone and Hamilton Counties, Iowa. Our initial focus is on landowner outreach, putting an emphasis on understanding the needs and culture of each individual community and resident.

Many of the details about the proposed Great Pathfinder Wind project are yet to be determined. For example, it's far too early to determine which wind turbine model we will use and exactly how many there will be within the project. However, as we continue to develop this project, more of these details will be determined, and we will share project updates with you here on this site.


  • Project size: Up to 225 MW 
  • Enough energy to power up to 85,230 U.S. homes
  • Turbines will be spaced approximately 1/4 mile apart
  • Existing high-voltage power lines and highways would limit the need for new infrastructure
  • Up to 200 local construction related jobs and significant local spending during construction
  • 15-20 full-time jobs created for operations and maintenance



Great Pathfinder Wind will represent a significant private investment in Boone and Hamilton Counties, boosting the local economy in the near term with construction jobs and local purchasing of materials and services. In the long term, the project promises to bring sustained tax revenue to the county for the local government and schools, as well as 30 years of local purchasing, employment, and investment.

The project site was selected by Apex Clean Energy after a thorough examination of many candidate sites within Iowa for the following reasons:

  • Verified wind resource
  • Existing high-voltage power lines
  • Expansive private land
  • Proximity to state highways


The cost of wind energy has dropped more than 50% over the past five years, providing a cost-competitive source for clean electricity across the nation. Wind powers the equivalent of 20 million American homes each year.* Wind energy comes with many benefits, including reduced pollution, increased domestic employment, consumer cost savings, water conservation, nationwide availability, and increased community revenues.** Wind turbines compliment working farms, because they allow for existing agricultural operations to continue around them. They also help farmers by diversifying the rural economy and providing a consistent, drought-resistant new harvest.


We are early in the development process for Great Pathfinder Wind, and there are many steps remaining in the process to complete the project. Apex is currently working to develop a project layout, and studies will continue for several years before construction can begin. This process typically takes about three years, which means construction is planned for 2021. Apex will be working closely with Boone and Hamilton Counties on the project planning and permitting of Great Pathfinder Wind, offering additional opportunities for the public to provide input throughout the process.
