A series of new and upgraded transmission facilities equaling 250 miles (spanning an area of approximately 173 miles) is being built to deliver electricity from renewable wind energy generators in Kern County south through Los Angeles County and east to the existing Mira Loma Substation in Ontario, San Bernardino County.
by renewable power sources such as wind. The Tehachapi Renewable Transmission Project, which would interconnect renewable wind energy to the existing electric system, would help meet an important state requirement concerning renewable resources. State law requires that at least 33 percent of the electricity SCE delivers to customers be produced by renewable sources by 2020. New and modified transmission facilities are needed to help the state meet that target. TRTP can help meet these targets.
In order to increase its ability to deliver this renewable wind energy to customers, SCE must upgrade its transmission lines and substations south of the Tehachapi Wind Resource Area by constructing the TRTP. These upgrades are also necessary to serve Southern California’s overall growing demand for electricity. (Southern California Edison, IQRA Associates)
