The Cherokee Nation has set up a SODAR North of Newkirk, Oklahoma to evaluate a potential site for a wind energy project. The SODAR emits a phased array sound signal that is used to determine wind speed and direction and to characterize wind turbulence profiles. The SODAR, which operates on the principle of the acoustic Doppler effect, provides high-resolution measurement data from 15 meters to 200 meters above ground level. The SODAR's operating frequency and physical design minimize the environmental impact of noise pollution. The SODAR began operation in August of 2004. The purpose of the SODAR wind energy study is to examine the feasibility of developing the Cherokee Nation's wind energy resources. The Cherokee Nation proposed the study to take place at two locals, the first is located in north central Oklahoma near the town of Newkirk Oklahoma and the second is west of Tulsa Oklahoma near the town of Kansas Oklahoma, which was formerly a swine operation and is referred to as the "Hog Farm". Both rural locations possess the capability to aid the tribe and surrounding communities if a wind development project is carried through.
The Cherokee Nation's Newkirk location is where the current study is being held, this consists of approximately 4,000 acres that are being utilized for agricultural purposes. Two Small farming communities and one medium sized city are located in close proximity of the study area they are the town of Newkirk, OK, Arkansas City, KS, and Ponca City OK.
Funds generated from wind energy sales could be utilized to supplement other Cherokee Nation programs or used to develop more wind energy initiatives. Other Cherokee Nation wind energy projects could also be developed within the 14 county service area of the Cherokee Nation.
The SODAR unit was chosen to undertake this project due to the flexibility of the equipment and less space is needed to operate the equipment. The practical height limit for meteorological towers is about 150 m (500 ft). Most SODAR systems will obtain reliable data up to 200 m. Using a SODAR system instead of a tall tower will also avoid many liability issues. SoDAR Info
If the data collected indicates that the site being investigated is appropriate for a wind energy farm then the Cherokee Nation will analyze what options will be pursued.
