Twin Groves Wind Farm yields significant economic benefits to the community in the form of payments to landowners, local spending, and annual community investment.

Twin Groves represents a capital investment of approximately $871 million and has disbursed $34 million in cumulative payments to local governments through 2019. The project created 397 full-time equivalent jobs during construction as well as 34 permanent jobs. Through 2019, approximately $66.1 million has been spent within 50 miles of the wind farm.

Wind Turbine Magic Hour


Twin Groves Wind Farm saves more than 704 million gallons of water each year and displaces carbon emissions from fossil fuel power plants, a major contributor to climate change. Wind energy also enhances air quality by helping to mitigate the health effects of harmful air pollutants.



Twin Groves Wind Farm is compatible with other land uses and provides a stable form of income to local landowners. More than $29.3 million has been paid to the wind farm’s landowners through 2019. These supportive landowners participate in long-term lease and easement agreements that cover turbines, access roads, and transmission corridors.

Modern wind turbine generators are sophisticated, high-tech machines designed to capture the kinetic energy of the wind and convert it into electricity. A turbine’s blades capture the wind and rotate an internal shaft connected to a gearbox spinning a generator to produce electricity.

Twin Groves I Wind Farm consists of 120 Vestas V82 1.65 MW wind turbines, and Twin Groves II Wind Farm consists of 120 Vestas V82 1.65 MW wind turbines.
