MidAmerican Wind has acquired the 168-MW Alta Wind VII and the 132-MW Alta Wind IX projects. California Highwind Power, a subsidiary of Terra-Gen Power, LLC, developed the projects, which are located near Tehachapi, California, U.S.

Terra-Gen is developing the proposed 1,550-MW Alta Wind Energy Center in 11 phases in Tehachapi. Seven phases totaling 1,020 MW were completed by the end of 2011. The 138-MW tenth phase and 90-MW eleventh phase are expected to be completed by January 2015. Terra-Gen may complete the latter two phases early and sell the power on the spot market.

The projects will interconnect to and use Southern California Edison's Tehachapi Renewable Transmission Project, and they will use a total of 100 Vestas 3-MW V90 wind turbines.
