Document Description
SDG&E is proposing to replace the aging 139/69 kV Mian Street Substation with a new 230/69 kV substation (Silvergate). The new Silvergate Substation would be located across the street from the existing Main Street Substation on SDG&E owned property and on adjoining property in the Barrio Logan community in the City of San Diego. In addition, SDG&E is proposing two associated projects: installation of a Special Protection System at transmission substations dispatching power from the South Bay Power Plant and 138 kV line undergrounding and removal of lattice steel bridge structures located within the SDG&E's right-of-way between South Bay Power Plant and the Sweetwater River.
