Introduction
Welcome to the California Public Utilities Commission (CPUC) website for the environmental review of proposed Sanger Substation Expansion Project. The proposed project will expand Pacific Gas & Electric’s (PG&E) existing Sanger Substation to accommodate a new breaker-and-a-half (BAAH) bus configuration. The substation is located southeast of the City of Fresno in unincorporated Fresno County, at the northwest corner of the intersection of East Jensen Avenue and South McCall Avenue. The application for the Permit to Construct (PTC) was submitted on September 30, 2015 (A. 15-09-012). This site provides access to public documents and information relevant to the CEQA review process. Additional project information and documentation will be posted as it becomes available.

Project Description
Sanger Substation, which was built in 1920, is integral to the Central Valley 115 kV transmission system because it serves as a strategic hub for routing Fresno’s hydro- and natural gas-generated electricity to the Manchester, Barton, Airways, California, Malaga, McCall, and Reedley substations. Sanger Substation’s twelve 115 kV power lines have the capacity to carry approximately 200 MW of generation annually, providing a critical energy path between Fresno metropolitan north and south areas. Sanger Substation will be expanded onto approximately 7 acres adjacent to and generally north and west of the existing substation.
PG&E is proposing to expand the existing Sanger Substation in unincorporated Fresno County, California, to contain a new breaker-and-a-half bus configuration. As proposed by PG&E, the project includes:
- Substation Expansion: PG&E would install equipment including circuit breakers, switches/disconnects, steel support structures for disconnect switches, bus supports and Capacitor Coupling Voltage Transformer equipment, two Modular Protection Automation Control (MPAC) buildings, and a microwave tower for communications. PG&E would also elevate the existing transfer bus and make alterations to interconnect reconfigured power lines.
- Substation Equipment Removal: PG&E would remove obsolete circuit breakers, switches, steel support structures, and the concrete control building at the existing substation.
- Power Line Reconfiguration: PG&E would rearrange existing power lines leading to the substation by removing existing lattice steel towers (LSTs) and wood poles and installing tubular steel poles (TSPs) in a different alignment. Existing power lines would be relocated to change their angle.
- Existing Substation Changes: On transformer bank 1, PG&E would remove wood poles that support a temporary line from the dead end structure and would replace them with a new TSP to terminate the new 115kV line for bank 1. On transformer bank 3, PG&E would relocate the existing dead end structure to terminate at the new 115kV line for bank 3 using new TSPs.
- Telecommunications Receiver: PG&E would install two antenna dishes on an existing microwave tower at the Fence Meadow Repeater Station.
The proposed project would increase reliability of electric service by upgrading the equipment at the existing substation to be in conformance with PG&E internal design standards as well as industry standards.
Project Location
The proposed project is located in unincorporated Fresno County, approximately 2 miles west of Sanger, California and approximately 3 miles southeast of Fresno. The existing Sanger Substation occupies an approximately 4.5-acre parcel at the northwest corner of East Jensen Avenue and South McCall Avenue. The expansion would cover approximately 7-acres adjacent to and generally north and west of the existing substation. The surrounding area is predominately agriculture and the existing substation is surrounded by vineyards and row crops. The closest rural residence is 200 feet north of the proposed expanded substation.
Application and Proponent’s Environmental Assessment
PG&E filed an application (A.15-09-012) for a PTC and Proponent’s Environmental Assessment (PEA) on September 30, 2015. The PEA provides information to begin the independent environmental review process conducted by the CPUC.

The mitigation measures and applicant-proposed measures (APMs) described in the Final MND were adopted by the CPUC as conditions of project approvals. A Notice of Determination was submitted to the State Clearinghouse (SCH #2017012039). The Commission Decision (Decision 17-07-008) can be viewed here.
Construction and Mitigation Monitoring
The first phase of construction began on November 5, 2018. The Notice to Proceed (NTP) approved for the project and is posted below and monthly compliance reports will be posted to this website are posted below.
Mitigation, Monitoring, Compliance, and Reporting Program
The CPUC developed a Mitigation Monitoring, Compliance, and Reporting Program (MMCRP) in coordination with PG&E to provide guidance and procedures for environmental monitoring during project construction. The MMCRP is a tool to ensure compliance with the applicant proposed measures (APMs) and mitigation measures approved in the Final EIR. The MMCRP was approved in May 2018. Version 2 of the MMCRP, with minor revisions, was approved on October 10, 2018.
The original MMCRP can be viewed here.
The revised MMCRP (version 2) can be viewed here.
