The turbines were installed at altitudes ranging from 3,000ft come 6,000ft over sea level in Tehachapi.

The an initial phase that AWEC started in July 2010. It included units ns to V, which to be completed in April 2011. Building and construction of devices VI and also VIII started in at an early stage 2011 and also was perfect in late 2011, and also building the the units VII and also IX began in April 2012 and also was perfect in December 2012.
