Geronimo began development on Audubon Wind Farm in 2010 and has since collected over four years of wind data. The project includes 55 landowners and a supportive surrounding community. Audubon is unique in that it offers flexible interconnection options, including the option to connect on-site to the MISO grid or to connect at a gas peaker plant as a net-zero project.


The Audubon Wind Farm is located in the middle west region of Iowa, approximately halfway between Des Moine, IA and Omaha,
NE. The average wind speed, measured at 80 meters, is 8.4 meters per second, which is just under 18.7 miles per hour. The prevailing wind direction is from the northwest and south.
