Welcome to the California
Public Utilities Commission (CPUC) website for the California
Environmental Quality Act (CEQA) review of proposed construction of
Southern California Edison (SCE) Triton Substation Project. An
application for this project was submitted to the CPUC on November 21,
2008 (Application
A.08-11-019). This site provides access to public documents
and information relevant to the CEQA review process.
Background
Southern California Edison (SCE) has filed an application with the CPUC
to construct the Triton Substation project for a new 56 megavolt ampere
(MVA) 115/12 kilovolt (kV) unattended substation (Triton Substation)
that would serve the cities of Temecula, Murrieta, and unincorporated
southwestern Riverside County. The Triton Substation is proposed to be
built on an approximately 10-acre parcel at the southeast corner of
Nicolas Road and Calle Medusa in Temecula, California. Click
here for a map showing the location of the proposed site.
The proposed project would also include construction of a 115 kV
loop-in from the existing Valley-Auld-Pauba 115 kV subtransmission line
into the new substation, two new underground 12 kV distribution duct
banks, and a telecommunications system to connect the proposed Triton
Substation to the existing Auld and Moraga substations. SCE’s existing
Canine 33/12 kV Substation in Temecula would also be retired when the
Triton Substation is operational. SCE has designed the Triton
Substation to eventually expand to 112 MVA at some future date,
depending on need.
SCE currently forecasts that the demand in the service area may exceed
the designed operating limits of the existing distribution facilities
as early as the summer of 2010. SCE has designed the project to meet
the long-term forecasted electrical demands of the cities of Temecula,
Murrieta, and adjacent areas of unincorporated southwestern Riverside
County while maintaining system reliability and enhancing operational
flexibility. SCE initially proposed to construct the project from
approximately October 2009 to May 2010. If the CPUC approves the
project, the earliest construction would begin would be spring 2010. If
approved, construction is estimated to take 8 months. The estimated
cost of the proposed Triton Substation is approximately $29.9 million
in 2008 constant dollars.
Application and Proponent’s Environmental
Assessment (PEA)
The application
and PEA
for the Triton Substation Project are available to view.
The CPUC sent SCE a deficiency letter on December 22, 2008. The CPUC
found the application and the additional information that SCE submitted
in response to satisfy the Commission’s Information and Criteria List
and determined it to be complete on April 30, 2009.
Environmental Review Process
As the lead CEQA agency, the CPUC circulated a Draft Mitigated Negative
Declaration (Draft MND) and supporting Initial Study (IS) on November
18, 2009. The Draft MND/IS describes the project, evaluates potential
environmental impacts, identifies impacts that could be significant,
and presents mitigation measures that would avoid or reduce potential
impacts to less than significant levels.
