SDG&E Supports San Diego Transmission Link

LCG, Oct. 8, 2001--San Diego Gas & Electric Co. on Friday filed with the California Public Utilities Commission testimony strongly backing construction of its proposed $271 million, 31-mile Valley-Rainbow Interconnect transmission power-line.

The line, which could be completed by 2005, would link SDG&E's system at Rainbow and the Southern California Edison Co. system in Romoland.

"Whether or not new power plants are built in the region, the construction of the proposed project remains critical to the state's future electric reliability," SDG&E said in a statement.

"Due to the ever-changing landscape of the state's electric picture, we decided to test the need for the 500,000-volt Valley-Rainbow Interconnect by carefully exploring several different scenarios involving the need for the line," said James P. Avery, senior vice president of fuel and power operations for SDG&E.

"In each case, the common conclusion was that this project is required in 2005 and grows in importance every year thereafter. In our view, SDG&E's CPUC-mandated obligation to serve its customers with a reliable source of energy must involve the construction of this project."

Once completed, the Valley-Rainbow Interconnect could connect the state's sources of power with a pathway that can accommodate as much as 1,000 megawatts.

"Providing an enhanced electric pathway linking power sources to the north and south should help put downward pressure on electric costs by enhancing competition while bolstering reliability for all electricity users in the region," Avery said.

In the event that Southern California Edison's existing 500 kilovolt transmission system is interrupted, the Valley-Rainbow Interconnect would serve as an emergency backup for southwest Riverside County, Avery added.
