Tehachapi Renewable Transmission Projects: The PUC approved construction of the Antelope-Vincent 500kV (Segment 2) and Antelope-Tehachapi 500kV and 220kV (Segment 3) Transmission Projects (A.04-12-008) on March 15, 2007. The Antelope-Pardee transmission line project in the Tehachapi area was approved by the PUC on March 1, 2007. When completed, the Tehachapi Renewable Transmission Project will provide 4,500 MW of capacity from the wind-rich Tehachapi resource area into the LA Basin. The Segments 1, 2, and 3 are projected to be on-line 2010, providing 750 MW of capacity at an estimated cost of $250 million. Southern California Edison (SCE) filed an application for a CPCN for the rest of the project (Segments 4-11) on June 29, 2007 (A.07-06-031). Those segments are projected to be constructed between 2011 and 2013 for an estimated cost of $1.8 billion. For information about the environmental review process on A.07-06-031, click here.
