Northern San Joaquin 230 kV Transmission Project

PG&E's proposed project for electric updates in Northern San Joaquin County

PG&E submitted the project application and Proponent’s Environmental Assessment (PEA) to the California Public Utilities Commission (CPUC) Energy Division. View PG&E’s Application and PEA on the CPUC Energy Division CEQA Project Website (PDF).

Project status

PG&E is proposing a series of electrical upgrades in Northern San Joaquin County, known as the Northern San Joaquin 230 kV Transmission Project. This project was formerly called the Lockeford-Lodi Area 230 kV Development or Northern San Joaquin Power Connect. It will help us continue providing safe and reliable electric service. We submitted a permit application for this proposed project to the California Public Utilities Commission (CPUC) on September 1, 2023. The CPUC will conduct an environmental review under the California Environmental Quality Act (CEQA) and will review the project need and costs before making a decision on the proposed project. Visit the CPUC project website for the latest project news.

Project details

  • The project will connect an existing electrical 230 kilovolt (kV) line into our Lockeford Substation.
  • We will also rearrange connected portions of our electric 60 kV system in the area.
  • A new 230 kV electrical line will connect our Lockeford Substation to a new switching station in Lodi.
  • The City of Lodi’s Electric Utility will construct a new substation to connect to the new switching station.

Our work with the community

To help us identify potential electrical line routes for the project, we gathered information through desktop studies, field studies, and input from the public and agencies. We then assessed each potential route based on three questions:

  1. Does the route meet the basic project objectives?
  2. Is it feasible?
  3. Does it avoid or lessen environmental impacts?

This assessment helped us identify the proposed project that was submitted to the CPUC. The CPUC is responsible for siting and routing this type of project. The CPUC may or may not select the project we are proposing.

Next steps

The project is now in the hands of the CPUC. They will conduct an environmental review process with opportunities for public input before making a final decision. To be sure your voice is heard, we urge you to learn about the CPUC’s process. You can find out when there are opportunities for public input and get more information at the CPUC’s website. For more information about the CPUC’s regulatory and environmental review process, including the CPUC-led public participation program, visit the CPUC website. The CPUC will now serve as the primary point of contact for comments on the project, and you can contact the CPUC by email at: NSJTP@ascent.inc or mail to the CPUC’s Project Manager, Boris Sanchez, California Public Utilities Commission, Energy Division - Infrastructure Permitting & CEQA, 505 Van Ness Avenue, 4th Floor, San Francisco, CA 94102, or by email at: boris.sanchez@cpuc.ca.gov To obtain additional information on the proposed project, please visit the CPUC Energy Division CEQA project website.
