May 30, 2008 May 30, 2008 ROSEMEAD, Calif., May 30, 2008 — Southern California Edison (SCE) today applied to the California Public Utilities Commission for authorization to build the Cross Valley Loop Transmission Project, a new, 19-mile, 220-kilovolt transmission line that would allow SCE to increase its capacity to deliver electricity to Tulare County during periods of high electricity demand. The county is one of the fastest growing regions in California. SCE proposes to build the new transmission line to connect two existing transmission lines from SCE’s hydroelectric facilities in the Sierra Nevada Mountains to SCE’s Springville Substation, east of Strathmore, Calif., and SCE’s Rector Substation, southeast of Visalia, Calif. The project would go through the city of Farmersville, Calif., and the community of Lemon Cove. The project SCE is seeking to build is similar to a project proposal that was shared with Tulare County residents in late 2006 and early 2007. While SCE has identified three potential routes for the project, the first alternative is SCE’s preferred route because it has the least amount of environmental impacts and is the least costly. Les Starck, SCE’s vice president, Local Public Affairs, said this much needed project would allow SCE to increase its capacity to deliver electricity from SCE’s hydro-electric facilities in the Sierras to the Rector Substation to serve Tulare County. “The construction of the Cross Valley Transmission Project would provide new facilities that would help minimize the likelihood of unanticipated outages in Tulare County,” Starck said. “Completing the proposed project is essential to meeting the region’s energy needs.” During the next five years, SCE will invest approximately $5 billion to expand its system-wide transmission grid and access new economical and renewable resources for its customers to ensure that Southern California has the robust power delivery system needed by a growing region.
