Tehachapi Wind Resource Area


Tehachapi Wind Resource Area, also known as TWRA, is considered the largest wind resource area of California.

Geography

The resource area is located in Kern County at the southern end of the San Joaquin Valley and spreads through Tehachapi Pass into the adjacent Mojave Desert. It is the home of many large scale wind farms which collectively produce more power than any other wind development in the United States.

Tehachapi Renewable Transmission Project

The development of the Tehachapi Wind Resource Area has been in the planning since 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.
