Windmills along Tehachapi Pass, California.

The east and south area of the Tehachapi Pass has one of California's larger Wind farms, generating electricity. The turbines have been in place since the early 1980s and have been upgraded through the years. The original wind turbines were much smaller than the much taller and larger new version turbines now sited for use. They are easily seen from State Route 58 and from Tehachapi-Willow Springs Road.

In a recent move, Southern California Edison plans to secure 1,500 megawatts (MW) or more of power generated from new projects to be built in the Tehachapi area. The 2006 contract, which more than doubles SCE’s wind energy portfolio, envisions more than 50 square miles of wind parks in the Tehachapi region, which is triple the size of any existing U.S. wind farm.
