The first phase of Southern California Edison’s massive renewable energy transmission project is ready to go, the utility said Tuesday.

Right out of the gate, the segment will be able to deliver 700 megawatts from far-flung wind farms, solar installations and other alternative energy sources. The utility revealed the completed portion Tuesday morning at its Windhub substation facility in Mojave.

The entire Tehachapi Renewable Transmission Project, once completed, will span from eastern Kern County to the city of Ontario in San Bernardino County, passing through parts of the Antelope Valley, the Angeles National Forest, the San Gabriel Valley and the western Inland Empire.

With more than 250 miles of infrastructure, the system will be able to carry 4,500 megawatts of electricity, or about enough energy to power 3 million homes.


The project is the first in the state to be built specifically for transmitting clean power.
Southern California Edison, whose parent company is Rosemead-based Edison International, said it expects to invest $5.5 billion on the transmission grid over the next five years.
