San Diego Gas & Electric (SDG&E) have announced details of its proposed route for the Sunrise Powerlink.
The proposed routes use SDG&E’s existing transmission rights-of-way, as well as land under the jurisdiction of a number of local, state and federal agencies, and some private property.
In certain areas, SDG&E plans to remove or consolidate lower-voltage transmission poles and wires with the new line, and is considering placing portions of the line under ground where there are no facilities now or where SDG&E’s rights-of-way are not wide enough.
SDG&E has divided its preferred path for the line into four segments Desert, Central, Inland Valley and Coastal to help facilitate ongoing discussion of the proposed and alternate routes.
Desert: This part of the 500-kilovolt (kV) line runs about 55 miles through a mostly uninhabited area from an existing substation in the Imperial Valley along a utility right-of-way through a portion of the Anza-Borrego Desert State Park.
Central: This portion of the project includes both 500-kV and 230-kV segments and travels another 35 miles to end at a proposed new substation on property owned by the Vista Irrigation District near the junction of S-2 and SR-79. Alternate substation sites are near the Santa Ysabel area.
Inland Valley: This 230-kV portion travels about 25 miles along SDG&E’s rights-of-way or roads in the community of Ramona, but also includes potential underground options through some populated areas.
Coastal: This 230-kV portion of the project runs about 15 miles through existing utility easements in the communities of Scripps Ranch, Rancho Penasquitos and Torrey Hills.
