In the most recent demonstration of its national leadership role in renewable and alternative energy, Southern California Edison (SCE) has begun construction of the largest wind transmission project in the
When all phases are developed, the Tehachapi Renewable Transmission Project will include a series of new and upgraded high-voltage transmission lines capable of delivering 4,500 megawatts of electricity from wind farms and other generating companies in
The first three segments include the following components: two new substations — Windhub and Highwind — located near Mojave and Monolith; a new, 25.6 mile, 500 kilovolt transmission line connecting SCE’s existing Antelope Substation with the new Windhub Substation; a new, 9.6 mile, 220 kilovolt transmission line connecting the Windhub Substation and the Highwind Substation; a new, 21.0-mile, 500 kilovolt transmission line connecting SCE’s existing Antelope and Vincent substations; and a new, 26.7-mile, 500 kilovolt transmission line connecting SCE’s existing Antelope and Pardee substations. The new lines are expected to be operational in early 2009.
“Southern California Edison is the nation’s leader in renewable and alternative energy, and we are continually looking for ways to expand our renewables portfolio,” said Alan J. Fohrer, chairman and chief executive officer of Southern California Edison, the utility subsidiary of Edison International. “The Tehachapi project is an example of the company finding a progressive way to meet increased energy demands of our customers and meet state officials’ desires to enhance the state’s renewables portfolio.”
The Tehachapi project is the first major transmission project in
“Construction of the Tehachapi project will create the single largest power block of wind energy in the
Other phases of the project are in the regulatory and approval stage. The project, if completed in 2013 as proposed, would be capable of carrying 4,500 megawatts of electricity, enough energy to supply nearly 3 million homes at peak output. One megawatt is enough power to serve about 650 average homes at a given point in time.
“The Tehachapi project not only will facilitate the interconnection of new wind generation, but also will improve grid reliability to help meet the state’s growing demand for electricity with renewable energy,” said Dian Grueneich, the lead CPUC commissioner on the Tehachapi project.
In addition to bringing significant wind energy resources to the

The Tehachapi project is part of SCE’s five-year, $5 billion transmission expansion program designed to ensure that
SCE is the nation’s leading purchaser of renewable energy. In 2006, SCE delivered about 13 billion kilowatt-hours of renewable energy, 17 percent of its total power deliveries — enough renewable energy to serve 1.8 million homes for an entire year. Energy contracts signed by SCE from 2002 through 2007 account for approximately 4,200 megawatts of SCE’s renewable energy portfolio, the equivalent of about four major power plants.
