Scoping Report (14 MB)


SDG&E filed an application for a Permit to Construct the Salt Creek Substation Project (project) with the CPUC. The proposed project consists of the following components:

  • Construction of a new 120 MVA 69/12 kilovolt (kV) distribution substation in the City of Chula Vista 
  • Construction and operation of a new 69kV single circuit powerline, approximately 5 miles in length, running between the proposed Salt Creek Substation and the existing Miguel Substation
  • Construction and operation of an underground loop-in of the 69kV powerline to the proposed Salt Creek Substation
  • Installation of a new 69kV powerline position at the existing Miguel Substation to connect the new powerline

The proposed substation site and the majority of the proposed powerline are located in the City of Chula Vista. Approximately 1 mile of the northernmost portion of the powerline is located in unincorporated San Diego County.

The proposed project is needed to serve the rapidly growing communities of Otay Ranch and Eastlake, and the  foreseeable future development of currenlty undeveloped land in the eastern portion of the City of Chula Vista.

Application and Proponent's Environmental Assessment (PEA)

On September 25, 2013, SDG&E submitted an Application for a Permit to Construct, including a proponent's environmental assessment (PEA) for the Salt Creek Substation Project and is available here. The PEA is a starting point for the independent environmental review process conducted by the CPUC. 

SDG&E's Application and PEA were deemed complete by the CPUC on May 19, 2014.
