Project Name: Silvergate
Transmission Substation Project

Application Number:
A. 05-03-024
On September 7, 2006 the California Public Utilities Commission (CPUC) granted San Diego Gas and Electric Company (“SDG&E”) a Certificate of Public Convenience and Necessity for the construction of the Silvergate Transmission Substation Project. In September 2006, SDG&E will begin construction of the Silvergate Transmission Substation Project and complete the project by December 2008 to meet the electric reliability needs of customers in SDG&E's service area.

Purpose of Project: SDG&E is constructing a new substation to replace outdated and obsolete equipment to assure reliability to the customers in the downtown San Diego area. This new substation will provide increased substation reliability, increased transmission reliability, expansion capability to allow for future load growth and generation as well as working with local governments to achieve long-term land use goals.

Project Description: This project primarily consists of replacing SDG&E's aging 138/69 kV Main Street Substation with a new 230/69 kV substation across the street on the SDG&E owned Silvergate Power Plant site and on adjoining property that SDG&E has acquired. This new substation will be called Silvergate Substation. In addition, SDG&E will complete the following associated project: The undergrounding of one 138 kV circuit between SDG&E's South Bay Switchyard (located next to South Bay Power Plant) and the Sweetwater River. After the Silvergate Substation is constructed and operational the following associated projects will be completed: The removal of two 138 kV overhead transmission lines between SDG&E's South Bay Switchyard and SDG&E's existing Main Street Substation, and the removal of 18 lattice steel bridge structures between the South Bay Power Plant and the Sweetwater River.

Project Location: The Silvergate Transmission Substation Project is located in the Barrio Logan area of San Diego. The underground routes for the transmission line are located within SDG&E existing right-of-way along the Chula Vista bay front to the Sweet water River.

Electric and Magnetic Fields (EMF): SDG&E will employ measures to reduce public exposure to EMF in accordance with CPUC Decision 93-11-013 and SDG&E's “EMF Design Guidelines for Transmission, Distribution, and Substation Facilities”. SDG&E filed copies of its Magnetic Field Management Plan for this project as part of the approved Application.

Construction Activities: Starting on or about September 24, 2006, SDG&E contract crews will begin work on the undergrounding of the 138 kV transmission line located in the Chula Vista bay front which is estimated to be completed in approximately 12-16 months. Both SDG&E crews and contract crews will generally perform work between the hours of 7:00 AM and 7:00 PM (Monday through Saturday), or for a shorter period if so stipulated in the relevant local (City or County) noise ordinance. Exceptions shall apply only where nighttime and weekend construction activities are necessary to mitigate for traffic impacts or as required by the California Independent System Operator or other system outage requirements.
Starting on or about November 7, 2006, work will begin to demolish buildings at SDG&E's Silvergate Power Plant site. Work is currently underway at this location to dismantle and remove equipment inside the building in preparation for the demolition work.

Notifications: As SDG&E progresses with construction, property owners within 300 feet of the proposed project will be notified by door hangers with SDG&E contact information and relevant dates construction will occur. Construction related activities may temporarily increase local noise levels, dust and other construction disturbances. To help reduce noise or other disturbances, property owners should close windows and other openings facing the planned construction.

Additional Project Information: To obtain further information of the project, including information on the construction schedule for where and when SDG&E will be working in your area, please contact Ahmad Solomon at SDG&E at 1-866-658-1778.
