Segments 2 and 3 of SCE's Renewable Energy Transmission Project Approved

The California Public Utilities Commission (CPUC) today approved Southern California Edison's (SCE) application to build segments 2 and 3 of the Tehachapi Renewable Transmission Project.

When all phases are developed, the Tehachapi project will include a series of new and upgraded high-voltage transmission lines capable of delivering up to 4,500(a) megawatts (MW) of electricity from wind farms and other generating companies that are proposed for northern Los Angeles and eastern Kern counties.

SCE has proposed constructing the Tehachapi project in 11 segments to coincide with the development of independently owned wind farms. Segment 1 was approved by the CPUC on March 1 and is pending approval by the U.S. Forest Service. Segments 2 and 3 include four components: two new substations to be named Windhub and Highwind, located near Mojave and Monolith, a new, 25.6-mile, 500-kilovolt (kV) transmission line connecting SCE's existing Antelope Substation with the proposed Windhub Substation, and a new, 9.6-mile, 220 kV transmission line connecting Windhub Substation with Highwind Substation. The new line is expected to be operational in early 2009. SCE will file an application next June to build the remaining segments.

"The Tehachapi project will strengthen and enhance SCE's transmission system by creating a new path for renewable energy to meet the increasing electricity demand of Southern California," said Ron Litzinger, SCE senior vice president of transmission and distribution.

Litzinger said that this favorable decision is an important step in SCE's efforts to deliver electricity from wind farms in eastern Kern County in support of meeting California's greenhouse-gas reduction and renewable energy procurement goals.

The Tehachapi project is part of SCE's five-year, $4.3-billion transmission expansion program designed to ensure that Southern California has the robust power delivery system needed by a growing region.
