Southern California Edison’s (SCE) Tehachapi Renewable Transmission Project (TRTP) is the first major transmission project in California being constructed specifically to access multiple renewable generators in a remote renewable-rich resource area. TRTP will consist of over 250 miles of new and upgraded high-voltage transmission facilities. The project will extend from eastern Kern County to the City of Ontario in San Bernardino County, traversing portions of the Antelope Valley, the Angeles National Forest, the San Gabriel Valley, and the western Inland Empire. When complete, TRTP will be part of a comprehensive program to provide the high-voltage transmission infrastructure necessary to interconnect and deliver the renewable wind resources being developed in the Tehachapi Wind Resource Area to SCE customers and the California transmission grid.

Completing TRTP is an essential component to meeting California’s renewable energy goals. California was the first state to set a 20% renewable energy goal. The California Renewables Portfolio Standard (RPS) was established in 2002 by Senate Bill 1078. The RPS requires investor-owned utilities, such as SCE, to increase their sale of electricity produced by renewable energy sources to 20% by 2010.
