Tehachapi Wind Resource Area


The Tehachapi Wind Resource Area is a large wind resource area along the foothills of the Sierra Nevada and Tehachapi Mountains in California. It is the largest wind resource area in California, encompassing an area of approximately and producing a combined 3,507 MW of renewable electricity between its 5 independent wind farms.
The mountain pass acts as a venturi effect to air moving between ocean and desert, increasing wind speed.
This area is a net exporter of generation to other parts of the state of California. A state initiative to upgrade the transmission out of Tehachapi began in 2008 and was completed by 2016. This has opened the door to further regional wind power development up to 10 GW, and multiple solar and storage projects are installed to utilize that capacity. A prime location for viewing the turbines is off of State Route 58 and from Tehachapi-Willow Springs Road.

Tehachapi Renewable Transmission Project

The development of the Tehachapi Wind Resource Area began in 2009 in conjunction with the development of the Tehachapi Renewable Transmission Project. The transmission project was required to support new wind developments in the area at the time including Alta-Oak Creek Mojave Project which was part of Alta Wind Energy Center, the largest wind farm in the world as of 2013.
