Buffalo Bear Wind Farm

Buffalo, Oklahoma

Situated on the eastern edge of the Oklahoma pan handle, Buffalo Bear sits in a remote location. The landscape is accentuated by rolling hills and steep ravines comprised of layers of rock and elevation changes of up to 200 feet. The rough terrain required close coordination of various construction activities.

Due to the remote location, a portable concrete batch plant was brought on site for pouring the foundations. Excavation through layers of rock from three to four feet thick was required to install

the power cable. Mobilizing the crane from site to site through the steep elevation changes also increased the complexity of the project.

Thorstad’s role on this project was an EPC contractor. Thorstad designed and constructed the roads, foundations, and substation, erected the wind turbines and installed the collection system for this project.

Project was completed in October 2008.
