Project Profile

Dempsey Ridge: wind energy farm

The Dempsey Ridge wind project is located in Beckham and Roger Mills counties, in western Oklahoma, approximately 10 miles southwest of Cheyenne. The wind energy farm sits on over 7,500 acres of agricultural and grazing land. The project has a capacity of 132 MW, consisting of 66 wind turbines.

This project is also known as the “Big Smile” wind farm, named after an employee of the project developer who lost a battle with cancer.  



The project provides enough clean energy to power 46,000 homes. Each year, this renewable wind energy source saves the planet from nearly 225,000 metric tons of carbon dioxide. 


The wind farm created over 150 temporary jobs during construction and the on-going operation of the wind farm has created 13 new full-time, skilled local jobs.


The project will generate more than $20 million in tax revenue for Roger Mills County and provide supplemental income to participating agricultural landowners through its 99 lease agreements.
