Tehachapi Renewable Transmission Project Segments 1-3

The Tehachapi Renewable Transmission Project (TRTP) Segments 1 to 3 is a series of new and updated electric transmission lines and substations that will deliver electricity from new wind farms in the Tehachapi area to SCE customers and the California transmission grid. TRTP is a vital part of meeting California’s renewable energy goals. The California Public Utilities Commission (CPUC) approved project Segments 1 to 3 in March 2007 and construction is now underway.
California is the first state in the nation to set a goal that renewable energy must account for 20 percent of customers’ energy needs by 2010. Today, there exists the potential to tap thousands of megawatts of energy from renewable sources including wind, solar and geothermal. SCE is dedicated to utilizing these renewable energy sources to provide power to our customers.
At-A-Glance
Project description
220 kilovolt and 500 kilovolt transmission line upgrades and new substations between the Tehachapi Wind Resource Area in southern Kern County and Los Angeles County.
- Segment 1*: 26.5 miles of 500 kilovolt transmission lines from Santa Clarita to Lancaster
- Segment 2 **: 21.0 miles of new 500 kilovolt transmission line and 220 kilovolt transmission lines and modifications at the Vincent substation to Lancaster
- Segment 3a**: 25.6 miles of 500 kilovolt and 220 kilovolt transmission lines connecting SCE's Antelope Substation in Lancaster to a new substation west of Mojave in Kern County
- Segment 3b**: 9.6 miles of 220 kilovolt transmission lines from Mojave to east of Tehachapi
* Segment 1 was originally filed as Antelope Pardee Transmission Line.
** Segments 2 and 3 were originally filed as Antelope Transmission Project.
Communities potentially affected:
- Segment 1: Santa Clarita, unincorporated Los Angeles County, Angeles National Forest, Lancaster
- Segment 2: Unincorporated Los Angeles County (Vincent), Palmdale, Lancaster
- Segment 3: Lancaster, unincorporated Los Angeles County, unincorporated Kern County (Rosamond, Mojave)
Project status
Segments 1, 2, and 3a of the Tehachapi Renewable Transmission project are completed and energized. Work continues on the restoration plans for these segments.
Antelope – Pardee: Segment 1, complete October 2009
Antelope – Vincent: Segment 2, complete November 2009
Vincent – Windhub: Segment 3, complete December 2009
Segment 3b – 9.6 miles of 220 kilovolt transmission lines from Windhub to a new substation Highwind. The Highwind substation and connection to Windhub are a part of the project intended to meet interconnection needs by Renewable Generators. The construction of these non-network transmission facilities will begin when sufficient capacity on the lines is requested by generators.
