Welcome to the California Public Utilities Commission (CPUC) website for the
environmental review of proposed construction of the San Diego Gas & Electric
(SDG&E) Mira Sorrento Distribution Substation Project (proposed project) located
in the northwestern portion of the City of San Diego, California. SDG&E submitted an
application for this project to the CPUC on October 14, 2011 (Application
A.11-10-015 ).
The proposed project is subject to review under the California Environmental Quality Act
(CEQA). This site provides access to public documents and information relevant to the
CEQA review process.
Background
SDG&E filed an application for a Permit to Construct the Mira Sorrento
Distribution Substation Project with CPUC. The CPUC, as lead agency under
California law, will prepare a mitigated negative declaration (MND) to comply with CEQA.
SDG&E is proposing to construct a new 120-megavolt ampere (MVA), 69-/12-kilovolt
(kV) distribution substation with the loop-in of an existing 69 kV electrical transmission
line (TL665). The proposed 1.4-acre substation would be situated on a 3.7-acre parcel with
a 10-foot-high screening wall that would enclose the substation area.
The proposed substation at full buildout is planned to have 120 MVA capacity
with four 30 MVA transformer banks; four 69 kV tie lines; sixteen 12 kV circuits;
four 12 kV capacitors and four bays of standard steel rack approximately 30 feet
tall of 69 kV bus and 69 kV transformer; and one 40-foot-long x 20-foot-wide masonry
block control shelter. In addition, on the northeast side of the substation site, two tiered retaining walls would be constructed that would be approximately 32 and 20 feet in height. Access to the substation will be via two 30-foot-wide driveways from Mira Sorrento Place to the west of the substation.
Power would be supplied to the new substation by an existing SDG&E 69 kV
transmission line (TL665) that would require installation of underground transmission
facilities into the substation site. Initially, six 12 kV underground distribution
circuits would be installed and would be routed to Mira Sorrento Place to tie into the
existing underground system serving the area.
Project construction is expected to require approximately 18 to 24 months to complete.
SDG&E is proposing to construct the Mira Sorrento Distribution Substation in
the vicinity of Vista Sorrento Parkway and Mira Mesa Boulevard in the Sorrento
Mesa area within the Mira Mesa Community Plan area of the City of San Diego,
California. The proposed project site is situated approximately 9 miles north
of Downtown San Diego (see Regional Map
and Project Vicinity Map).
Application and Proponent's Environmental Assessment (PEA)
The application and PEA for the Mira Sorrento Distribution Substation
Project were filed with the CPUC on October 14, 2011.
