    Red Hills Wind Farm represents ACCIONA’s first renewable-energy project in the state of Oklahoma. Well known for its vast oil and natural gas reserves, Oklahoma will come to be recognized for its wind resources as well, currently ranking in the top 10 U.S. states for wind-energy potential. The surrounding community continues to build on its pioneering spirit through their support of Red Hills Wind Farm.


    Power generation

    The Red Hills Wind Farm delivers enough clean energy to power more than 40,000 U.S. homes. 

    Economic development

    Red Hills Wind Farm provides increased revenues for Roger Mills and Custer counties through investments in local infrastructure, lease agreements with local landowners and property tax revenues from the project over its lifetime. The wind farm also offers an annual scholarship to graduating seniors from Hammon High School.

    Community and environmental sustainability

    During the four-year site development phase, ACCIONA participated in an extensive county permitting and review process. The company also conducted biological assessments, bird and bat impact studies, and wetland delineation to address wildlife concerns. Public meetings held in Cheyenne, Oklahoma, the Roger Mills County seat, in February and June 2008, allowed local communities the opportunity to review the wind farm maps and pose questions regarding the results of environmental impact studies. Following these meetings, ACCIONA secured the permits required to begin construction.
