This website provides information about the California Public Utilities Commission’s (CPUC’s) review of the Northern San Joaquin 230 kV Transmission Project pursuant to the California Environmental Quality Act (CEQA).
CPUC Review Process
Pacific Gas & Electric Company (PG&E) filed an Application for a Certificate of Public Convenience and Necessity Authorizing the Construction of the Northern San Joaquin 230 Kilovolt (kV) Transmission Project on September 1, 2023 (CPCN Application No. A2309001). Following receipt of a complete application, the CPUC conducts two parallel processes when considering development proposed by a regulated utility: an application process, in which the CPUC reviews the utility’s proposal and considers whether the project is needed and is in the public interest; and an environmental review process pursuant to CEQA. The CPCN application process focuses on utility ratepayer and public benefit issues and is undertaken by the CPUC’s Administrative Law Judges Division. The CEQA process for utility applications is led by the CPUC’s Energy Division.
Through Decision 26-07-042, the CPUC granted PG&E’s request for a CPCN authorizing the construction of the Northern San Joaquin 230 kV Transmission Project subject to the mitigation measures identified in the Mitigation Monitoring and Reporting Program. This decision finds and certifies that the Final Environmental Impact Report (EIR) for the Northern San Joaquin 230 kV Transmission Project meets the requirements of the CEQA.

Project Overview
Location
The project would be located primarily in northeastern San Joaquin County and in the City of Lodi, with remote-end facilities in Contra Costa County, Linden, Lodi, Rio Oso, and Sacramento.

Project Summary
The proposed project entails construction and operation of a new 230 kV transmission system with approximately 10.6 miles of new double-circuit 230 kV transmission lines, an expanded substation, a modified substation, a new substation, a new switching station, reconfiguration of four existing 60 kV lines, relocation or extension of two existing 12 kV lines, and upgrades at four remote-end substations and one repeater station.The project would loop PG&E’s existing overhead Brighton-Bellota 230 kV transmission line through PG&E’s Lockeford Substation and install a new overhead double-circuit 230 kV transmission line between PG&E’s Lockeford Substation and PG&E’s new Thurman Switching Station at the City of Lodi’s existing Lodi Electric Utility (LEU) Fred M. Reid Industrial Substation in Lodi, California. LEU would construct the LEU Guild Substation, a new 230/60 kV substation, between the existing LEU Industrial Substation and the new PG&E Thurman Switching Station. At the LEU Guild Substation, the new PG&E 230 kV transmission line would terminate, and LEU transformers would step down the power to 60 kV to connect with the LEU Industrial Substation. When the new 230 kV system is operating, the existing local PG&E 60 kV system would be reconfigured within existing alignments, including disconnecting as a source to LEU at the LEU Industrial Substation. Existing LEU and PG&E 12 kV service/feeder lines and a third-party telecommunication line within the City of Lodi would be modified during construction to allow reuse of an existing alignment, continuation of existing service, and construction new permanent secondary station service.
Applicant Objectives
The purpose of PG&E’s Northern San Joaquin 230 kV Transmission Project is to address reliability and capacity issues identified by the California Independent System Operator (CAISO) on the existing PG&E 230 kV and 60 kV systems serving the area between PG&E Lockeford and PG&E Lodi substations.As identified by PG&E, the objectives of the proposed project are to:
- Meet PG&E’s legal obligation to implement the CAISO-approved project.
- Improve system reliability for PG&E’s approximately 10,000 electrical customers, one of which is Lodi Electric Utility, which itself serves approximately 27,750 customers.
- Increase capacity to accommodate projected growth in demand and minimize future reliability issues.
- Address thermal overloads and voltage concerns on PG&E’s 60 kV transmission system identified during P1 contingencies and maintain compliance with North American Electric Reliability Corporation (NERC) standards.
- Address thermal overloads on PG&E’s 60 kV transmission system identified during P6 contingencies and maintain compliance with NERC standards.
- Reinforce the PG&E 60 kV system in the Lodi area by constructing a new 230 kV double-circuit line to provide an additional source of power.
- Construct a new 230 kV switching station to receive the new 230 kV double-circuit line and provide power to a new 230/60 kV substation to be constructed by LEU.
- Separate PG&E’s 60 kV system at the LEU Industrial Substation from LEU’s 60 kV system.
- Construct a safe, economical, and technically feasible project that minimizes environmental and community impacts.
Construction Progress and Mitigation Monitoring, Compliance, and Reporting
Notice to Proceed
PG&E must obtain a Notice to Proceed from the CPUC prior to initiating construction activities. No notice to proceed has been issued.
Mitigation Monitoring, Compliance, and Reporting
CPUC will develop a Detailed Mitigation, Monitoring, Compliance, and Reporting Program in coordination with PG&E that provides guidance and procedures for environmental monitoring during project construction.
Minor Project Refinements
CPUC's Energy Division may approve requests by PG&E for minor project refinements that may be necessary due to the final engineering of the project, so long as such minor project refinements are located within the geographic boundary of the study area of the EIR and do not: (1) result, without mitigation, in a new significant impact based on the criteria used in the EIR; (2) substantively conflict with any mitigation measure or applicable law or policy; or (3) trigger an additional discretionary permit requirement. A change to the approved project that has the potential to create significant environmental effects will be evaluated to determine whether supplemental CEQA review is required. Any requested changes to the project evaluated in the certified EIR that do not warrant supplemental CEQA review will be subject to CPUC review through the minor project refinements process. No minor project refinement requests have been submitted.
